Corsair RM750x (2018) 80+ Gold Fully Modular Power Supply $119 Delivered @ Amazon AU

790

Previously $139, Amazon has now dropped the price to $119, matching the now-expired eBay deal.

This is an excellent-quality power supply with Japanese caps and hydraulic bearing fan.

As for the differences between the RM750 and the RM750x, TomsHardware says this:

it uses Chinese Elite caps and a Hong Hua rifle bearing fan. The slightly more expensive RM750x comes with Japanese caps and the high-quality NR135L fan. Although those differences are notable, still the provided warranty is the same, at ten years, for both models.

Corsair released a new 2021 model so it looks like these are being cleared out, so stock probably won't last too long.

    Obligatory Modern Standby mention, which will become important if you wish to move over to Intel's Alder Lake (12th gen) CPUs, as well as future AMD CPUs, possibly as soon as Zen 4 (Ryzen 7000).

      If you are after those, is it really necessary to buy a PSU right now? What else do you need to stock up now?
      Also, honestly, if you are really after modern standby, is a desktop system a good idea? With majority of laptops not supporting modern standby yet, why is it such a big deal now? Furthermore, if Intel and AMD don't get their acts together, Apple M1 power usage is so impressive, no amount of modern standby will help.

      •  

        I'm not assuming what people are doing with their system builds and parts buying schedule, just chucking info in that wasn't included here.

        Smart builders will be using the same PSU for 10 years, so it's critical info for those purchasing today.

        •  

          There are other far more important aspects where the 2021 model is better, modern standby isn't really a factor.

          Furthermore, let's say you purchase a PSU with modern standby NOW, how are you going to test it to make sure it actually works. You expect people to already have the knowledge and the applications necessary to test?

            @netsurfer: We've already had the architecture discussion previously, and from a global perspective, reducing average power consumption helps your bills and helps your environment, and should be encouraged where economical and reasonable.

            As for the notion that the technology isn't tested and you'll just wind up with something that does nothing? C'mon now.

            •  

              @jasswolf: We are talking about 750W PSU…. Come on, seriously? We've been through this ALREADY.

              Current modern standby implementation on laptops put the laptops in even lower power usage level at hours which they don't expect you to be using the laptop (i.e. 3AM to 5AM). Thus, modern standby on its own isn't the best way to save power.

              Reducing average power consumption - honestly, IF that's what you are after, then you should only use desktop when you really need to. That's what I do, if I am just doing basic Web surfing, I don't need to use a heavy desktop (which wastes more power) and later on, use modern standby (to put it in low power usage mode).

                @netsurfer: Again, this is the worst possible series of defences you could ever use for this. Alder Lake changes the situation for desktops. If you think the software isn't going to catch up with the hardware, you're absolutely kidding yourself.

                As for not making the tiniest bit of effort and cost to reduce power consumption in your household? Grow up… look around you, look around the world. What are you doing to help?

                  @jasswolf: Come on, people going for 750W and 800W PSU, what do you think they are getting? Are they really getting the most power efficient GPU?

                  Honestly, it is more important for laptop makers to adopt modern standby first. Let's be honest here, both Intel and AMD are NOT after best power consumption. They are after profit - hence 14nm from Intel still and 7nm from AMD. 5nm is available now but the cost is high.

                  Are you doing your bit and actually purchase the most power efficient components? Given that M1 is the most power efficient desktop CPU, should we ALL get Apple M1 based setup and forget about Intel or AMD?

                      @jasswolf: It's all a lot of marketing hype. Where is PCI express 5.0 that Intel hyped up? So, it turns out we get PCI express 4.0 still from Intel.

                      Big.LITTLE from Intel - honestly, Intel has bigger woe and if we are looking at Intel's 10nm, the LITTLE cores won't be that efficient. Intel has lost that race long time ago.

                      The move to AMD currently for most people is that they deliver better performance per watt so in a way, people are doing the right thing. Is Alder Lake going to really deliver?

                      Please don't assume things. Most of the time, my family and I use power efficient devices. We only have 1 beefy desktop systems. All the other devices are power efficient type. Honestly, you are ASSUMING everyone needs Alder Lake.

                      @jasswolf: Before we get too carried away, let's look at a current implementation of modern standby on laptop, shall we?

                      This is from a Dell support article: The Battery drains quicker than expected on a Dell notebook with Modern Standby mode enabled

                      The whole article is long, but basically the cause provided by Dell is:

                      With Modern Standby, the system wakes when there is real-time action required, such as OS maintenance, or a user wakes the system.

                      The article then proceeds to guide user on how to turn off some of the modern standby features (which basically would disable OS update under modern standby). It also warns users things to watch out for (otherwise you could get Black Screen or Blue Screen).

                      Believe me, I want to support better power saving on PC. However, given the mess in the past attempts, I am not so sure it will be a smooth ride this time. On a laptop, all components are chosen so they should work. However, there are still software issue (basically we are NOT there yet).

                      When Modern Standby is fully ready and all our components are all ready for it (and the apps are all ready), then there should be a lot of PSUs available with modern standby. If you insist on getting a PSU with that now, you are limiting your choices. It's fine if you believe it is future proofing big time. However, it's also okay for people to be pragmatic and don't make it sound like the PSU is the most expensive PC component which shouldn't be upgraded for 10 years.

        Corsair RM750x (2021) - supports modern standby and further improves on the 2018 model

        However, the real attractive part of 2021 is actually those other improvements. There is no desktop system currently that supports modern standby.

            @jasswolf: So, let's think about it… RM750, you are going for inferior components. The 2021 model isn't available.

            The issue is that modern standby ISN'T the super duper power saving you hype up to be. Don't forget the word standby. It is about putting things on standby. Now, IF YOU WANT TO SAVE POWER, why is standby such a great idea? I told you that even the current implementation does try to put the laptop into even deeper sleep.

            If you are the type of person who will ensure you get modern standby on your laptops RIGHT NOW, then you have a point. You are talking about things which will happen in the future for PC and you are assuming people will re-use their PSU for Alder Lake CPU.

            I have a PC that has a bronze level PSU right now, I think by upgrading to gold level, it will help. I've tried and tested my intel PC and there is simply no modern standby, I just don't see how getting a PSU right now with modern standby will help. Perhaps you can explain THAT to me. I am not saying don't get one when it is available, I am just saying it is not a factor right now.

              @netsurfer: I just turn my PC off so I don't get what the hype is about.

              Might pick up one of the 2018s unless there's an actual benefit to the new one.

              @netsurfer:

              RM750, you are going for inferior components.

              AFAIK, this is actually pretty marginal, and mostly plays into Western stereotypes.

              The issue is that modern standby ISN'T the super duper power saving you hype up to be. Don't forget the word standby.

              Ah yes, because the other hardware in the chain don't need to properly support remaining suspended on wake or have lower-power modes either.

              If you are the type of person who will ensure you get modern standby on your laptops RIGHT NOW, then you have a point.

              People buying today, will mostly likely be using this PSU for 5-10 years. It's absolutely relevant for desktops.

              Don't reply to me further, because I've explained the entire argument. The hardware standard comes before the further implementation and software, that's how these things work.

              •  

                @jasswolf: People buying PSU now for their current PC. Now, for the people who can afford Alder Lake and will upgrade right away, I am pretty sure they can afford to get a new PSU then.

                Also, buying RM750 now isn't really that attractive. The 2021 model of RM750x is better in several ways. Thus, WHY is there a need to get RM750 NOW if modern standby is such a big deal?

                I just don't get why RM750 is such an attractive offer right now and being so wonderful.

                No matter how much you want to hype up modern standby, the real issue now is PC currently is not competitive at all in terms of power usage. Modern standby cannot save it. The M1 power usage is so low that I don't really think intel's LITTLE can beat it. The GPU part of it, from what I read, has really really low power usage and basically blows all embedded GPU in current AMD offerings. PC CPUs currently have really big issue power usage wise. It needs heaps more than modern standby.

      Of course, that's assuming one requires background app syncing during sleep, and quicker wakeup times. I thought about it and decided it wasn't a big deal for me. When I put my PC to sleep I expect it to sleep and use barely any power, rather than continously syncing in the background when I'm not around.

      Different people have different use cases of course; if modern standby is desired then the 2021 model would be the way to go, when it's available here.

        It scales a lot more than that, especially with big.LITTLE designs… you should have researched more.

          No need to be condescending. In any case, ATX12VO might be a desireable option by the time modern standby is widespread.

          All that is basically catching up to mobile devices. There is nothing modern about modern standby. You really wondered why it is taking PC so long to go down that path.

          big.LITTLE designs have been around for quite some time. How much is that is to basically make PC catching up to Apple? Furthermore, how much of that is for laptops? Sure, desktops can benefit from big.LITTLE. However, by the time they are available for desktops, are we sure we won't have better choices? By then, the 2021 model of the PSU should more readily available.

          How much can you actually save on idle power? The issue is that with SSD being ubiquitous, I am not so sure about whether it is worth it to put desktop PCs on standby a lot.

          For people who were on el cheapo PSU, upgrading to this could actually save electricity. By the time modern standby is really available (and honestly, are you 100% sure AMD will support it in the next round of CPUs?), then we look at it then. There are also apps which need to be changed.

            •  

              @jasswolf: So, the idea is, get a new CPU, motherboard, DDR5 memory, new SSD when they are available BUT get the PSU now?

              I don't understand the logic there. We use devices that support big.LITTLE a lot already: mobile phones, tablets. Honestly, only Apple desktop and/or laptop users need to decide whether to embrace big.LITTLE right now because the option is already available.

              You are assuming most people will jump right into Alder Lake with modern standby. Alder Lake needs to beat AMD by a decent margin for people to even consider it. You are better off pushing AMD to implement modern standby, rather than asking people to buy PSU with modern standby now.

                No, this is just a simple decision tree when you buy a PSU and you're thinking about trying to save $10-$20, for a unit you will use for 10 years.

                I don't understand how this is so challenging for you, and I'm not going to explain it any further, as I think it's doing both of us a disservice.

                •  

                  @jasswolf: Have you used a PSU for 10 years? I tried. I ran into so many issues I got fed up and got a new one. It was a bad idea to overspend on that PSU.

                  It wasn't just one issue, it was a lot of issues.

                  $119. Honestly, when PC modern standby is fully ready and it's time for me to build another desktop, I would just get a new PSU at the time. The chart we are basing our decision on PSUs is also getting dated. ATX12VO - gosh… is Intel really going to play that card?

                  RM750x (2021) is $10-$20 more? Or, you are trying to sell people RM750 again?

                  When you buy an Alder Lake system, you will need a PSU. I don't get the logic that you buy everything new except taking the PSU from an existing system. What happen to that old system? Toss it in the bin? Buy an el cheapo PSU?

                  I certainly hope the leaked benchmark for Alder Lake is wrong because if it is correct, it would mean we won't get competitive CPUs from Intel yet again and AMD will be laughing all the way to the bank again.

                  Let's be realistic, Intel has been milking customers for far too many years now (went from a market leader to the last position). If all intel is going to do is big.LITTLE with modern standby, then Intel can keep their Alder Lake. It'd better really have significant jump in performance.

      I turn my PC off when I'm not using it.
      Am I doing it wrong?

      •  

        No that's 100% right with today's hardware, this is a feature that will be built upon over time, that along with related features on upcoming hardware, will essentially set your PC up so it can complete background tasks with the least amount of power possible.

        It means the desktop PC that would basically be off, instead can sip power periodically to run updates, check for mail, notifications, etc. Similar to a phone, so that standby, resume from wake, idle, and low-power consumption (this part requires further hardware advancement beyond the PSU) is remarkably improved over time.

        If you're using a PSU over multiple builds, it's a factor to consider.

          Ah right, yeah just reading up on it now, never heard of it before.

          I'm going a pretty cheap built 11400f + B560m + 16GB RAM, with all my money going on a 30XX GPU when they become available.
          My current PSU is 10 years old so figure I could use an upgrade and this particular model fits the bill.

          Probably won't be upgrading for another 5+ years anyway as like to wait for tech to get better/cheaper.

          •  

            @putshan: I wouldn't worry about it at the moment (especially for desktop). Reasons are:

            • Modern Standby isn't trouble free. See my comment above. Dell has an article basically telling user how to turn parts of it off if it is causing excessive battery drain (basically, we are not ready for modern standby yet).
            • It's common sense. No matter how good the standby power drain is, it is still going to drain power. Whereas, if your PC is off, it doesn't drain power.
            • That's why most modern standby implementation has a scheduler which puts the computer into even deeper sleep because at the modern standby state, the power drain, while lower than current active standby, is still high enough that deeper sleep is preferred.
            • With SSD and fast boot, for most users, boot up a PC isn't that slow nowadays.
            • Big.LITTLE, frankly, will new CPUs all come with an efficient GPU core embedded? Otherwise, if we all go for external GPU, will the GPU makers embrace modern standby big time?

            Since when do people go for PC for its "superior" sleep, standby, resume, wake features? It has always been a weak point for PC and you seriously expect a new standard from Intel (with AMD not committing to support it) will magically fix?

        • -1 vote

          Is your desktop right now doing modern standby? Are you going to agree to let Microsoft perform every upgrade behind the scene? Wouldn't that mean you could be beta testing updates?

          The main issue I have with modern standby is that we have not actually seen it working 100% on the laptop side yet (so it's not trouble free yet). So, it is still work in progress. Let's not forget the laptop actually wants to go into even deeper sleep state than the modern standby state because even at that state, if it is not really doing anything, it is still sipping too much power.

          Also, at this price point, compared to several other PC components, the PSU isn't that expensive. Let's not forget why people are now after 750W and 800W PSUs.

      Modern Standby - Things to note:

      • Quite a number of laptops already support it. Some Intel NUCs support it for a few years now.
      • Intel NUCs default to S3 standby whereas newer laptops default to modern standby (with or without an option to switch).
      • When you switch from S3 standby to modern standby, you get a warning that it may not work and will require a reinstallation of the OS.
      • When things don't work well in modern standby, it can get frustrating. An example: Please fix modern standby issues!(dell.com)
      • The modern standby sources and rules aren't simple. You also have AC vs DC (battery) differences. Microsoft dictates / decides how it operates.

      So, assuming all motherboards for Alder Lake CPUs will support modern standby, make sure you decide whether you want it or not right away. It's likely M/B makers will default to S3 (on the safe side). Best to start with a fresh Windows install if you want to change.

      For a desktop PC, it's hard to make sure every component will work well with modern standby. You also need apps to take advantage of it. Is that so important that even if Alder Lake CPUs are slower than AMD ones, you will go for them because of modern standby?

  •  

    Good price, too bad just bought a second hand evga 1000w.

  •  

    Definitely good to get a decent PSU like this one, since they can last decades. 750W might seem like too much given most PCs, even with a big flagship CPU and GPU, won't need anywhere near that much, but these beefy CPUs are cool and efficient at lower wattages, and so can turn their fans off, making them quieter and cheaper over the life of the product.
