    Is this a good price and good power supply? Starting getting parts for my PC

      Yes and yes

    • Turgor on 26/04/2019 - 16:01

      Would depend on the other parts you're getting for your PC- but corsair is a reputable brand and I would recommend getting a good rated efficiency or higher.
      Use one of the online power calculators to determine what wattage power supple you require first.

    • Turgor on 26/04/2019 - 16:02

      *gold

    • Bigboomboom on 26/04/2019 - 16:03

      Yes and yes. I have one for my build 3 years ago for $175, it's extremely solid. It's also backed by 10 years warranty which is industry standard for higher end PSU (3-5 for normal/budget tiers).

    • sep1 on 26/04/2019 - 16:18

      This is good. With PSUs you will want to check the reputation of the brand, Corsair is reputable for reliable PSU. You will want to make sure the wattage satisfies the power requirements of your build, for example 750W might be pushing it if you want two GPUs and a sick liquid cooling setup. You will want to make sure that you are happy with the efficiency rating, gold is mid level, you can get platinum and titanium rated ones that obviously cost a lot more. And lastly make sure that the advertised metrics are not bogus by looking up the report on the 80plus.org website for that PSU.

      Power supply efficiency is a curve so ideally you'd want to aim for having the average system wattage to be at the peak of the curve. If the system doesn't draw enough power then you'd be wasting some energy and having paid extra for the PSU at the same time - a double whammy. One of the few situations when bigger isn't necessarily better. The CPU/GPU these days consumes a lot less power than the ones from more than 5 years ago so definitely look up the benchmarks of your target spec and size the PSU accordingly (rule of thumb is that peak efficiency is about 1/2 of the rated capacity).

      Personally I've got a 750W platinum (got it on the cheap) running a budget gaming build that hardly draws 220W at the max while gaming. So the efficiency is close to just 80-85% - a bit of a waste for my PSU.

    • gromit on 26/04/2019 - 16:47

      good PSU and a good price. But that doesn't mean it is necessarily the best or cheapest for you as it depends on specs of what you are building.

        Come on anyone who has built PCs knows Corsair PSUs are solid. The RM series is well reviewed.

          I've worked in IT a long time and played with / built computer a long time before that. From what I have seen Corsair are this company that makes great RAM, were well known for years for making basically the best consumer RAM. But then a few years back now suddenly you start seeing all these products with Corsair printed on them; headphones, keyboards and worse power supplies.

          Now you and other consumers can look at that how you want. I choose to see it as them just whoring their name to the highest paying OEMs. Corsair are a RAM manufacturer, not a keyboard maker, not a PSU maker so it is clear these products are not made by them but just get an expensive Corsair sticker put on them. I don't understand how I seem to be the only one that sees this, how everyone laps up their stuff ignoring established brands of manufacturers who actually design their own products.

          Yes "who makes the product" does get a bit ambiguous when things are made in the same Foxconn or similar factories, but to me there's a big difference between say Cooler Master (for instance) getting a power supply made in a factory, that they paid for to be designed and manufactured, and some OEM coming to Corsair and paying them money to use their name.

            @deelaroo: Corsair have never manufactured RAM.

            • deelaroo on 26/04/2019 - 18:18

              @Diji1:

              The company was founded as Corsair Microsystems in 1994 by Andy Paul, Don Lieberman, and John Beekley. Corsair originally developed level 2 cache modules, called cache on a stick (COASt) modules, for OEMs. After Intel incorporated the L2 cache in the processor with the release of its Pentium Pro processor family, Corsair changed its focus to DRAM modules, primarily in the server market. In 2002, Corsair began shipping DRAM modules that were designed to appeal to computer enthusiasts, who were using them for overclocking. Since then, Corsair has continued to produce memory modules for PCs, and has added other PC components as well.

              @Diji1: they make memory modules using other people’s dram.

              • Soothsayer on 26/04/2019 - 22:11

                @garage sale: This. He might have a point if we were talking about a PSU sold by Hynix but it makes no sense to apply this logic to Corsair, especially since they built up a PSU pedigree long before selling other components like cases and then peripherals. I used their HX-620 for over 10 years with no issues and it was the go-to enthusiast PSU in the mid-2000s.

        What a load of BS, just because they outsource the manufacturing to companies like seasonic (who are themselves also an excellent brand) doesn't mean jack. They don't rebadge junk. They have had an excellent reputation in PSU's for quite a lot of years now and the RM series is highly rated.

      • thatguyfromthatplace on 26/04/2019 - 18:02

        The RM series is built for Corsair by Channel Well Technologies. The only better OEM out there is Seasonic, who also build units for Corsair. You, sir, are talking out of your ass.

        • 4foxache on 26/04/2019 - 18:17

          Yeah best sick with Seasonic or EVGA (super flower). Personally I run a 650w platinum Seasonic 10yr warranty.

    • TheGoodPart on 26/04/2019 - 23:02

      This isn't a bad price but it is possible to get as good PSU's for cheaper. Also think about how much power your PC is going to be using. 500W may potentially be enough and can save you a bit of money.

  • azndraon on 26/04/2019 - 16:01

      If 550w is enough for your use, you really haven't missed out on anything.

      • scrambledeggs on 26/04/2019 - 17:12
        +3

        In fact, you want a PSU rated around 10-20% watts higher than your computer components require, this gives you the most energy efficient outcome. A 1500 watt PSU will use more electricity than a 750 watt power supply for most people for no benefit.

        • [Deactivated] on 26/04/2019 - 17:37
          +6

          It's actually untrue I believe. The usage of electricity is depending on the actual power draw from the other components. Having a bigger wattage PSU only means that the maximum power output can be higher if needed, doesn't mean your PC starts using more power.

          • toomuchdogfur on 26/04/2019 - 17:53
            +5

            @[Deactivated]: That's true, but eggs is referring to the efficiency of the PSUs when under the same load - as an example 80 Plus Gold guidelines state the PSU should be 90% efficient at 50% of their maximum rated load.

            So a 750W PSU would hit that efficiency with a 325W component load, drawing 325/0.90 = 361W power from the wall

            Put that 325W load on a 1500W 80 Plus Gold PSU = 25% loading. Guidelines state 87% efficiency at 20% load, so the 1500W PSU would draw about 325/0.87 = 374W of power from the wall.

            (This is probably an extreme example, but I hope you get the idea!)

          • garage sale on 26/04/2019 - 21:22

            @[Deactivated]: there is an efficiency curve and you want to run your setup on the sweet spot, and drawing 400w from a 1500w supply isn’t the sweet spot.

            • Soothsayer on 26/04/2019 - 22:28
              +2

              @garage sale: you are both right but clse945111 is probably more accurate to real-world usage for many modern PSUs, which can hit maximum efficiency from as little as 20% load. The PSU in this deal is actually most efficient between 200-400W , so for most single-GPU systems this would be ideal, but in either case the effect of wattage/rating on power draw is small compared to the other components in the system.

              Higher wattage PSUs also tend to have better build quality (but not always) and will often be much quieter due to slower fan ramp up and/or fanless light load modes.

              I get that it's good to remind newbies that you don't need to overspec a PSU but I feel in recent years it's gone too far the other way, due to people repeating each other over and over on reddit etc when they don't really understand. Annoys me a bit when people advise lower wattage PSUs are somehow better than higher wattage ones.

    Hey

    I’m building a mini itx in a nzxt 200 and I’m wondering whether it can accomodate a Atx power supply

    https://pcpartpicker.com/products/power-supply/?compatible_w…

    Reckon this would be good, I’m going I9 and 2080ti

    • ThePump on 26/04/2019 - 17:06

      The NZXT H200i can accomodate both ATX & SFX PSU units, this PSU would also be good for your i9 & 2080ti.

    CX750M is available for $135 from PC Case Gear. Mind you that's before shipping cost, so i guess this is a good deal. If the difference in price were significant, i'm guessing it'll take you many years (decades even) to recoup the extra $$ for Gold, if ever. As others have mentioned, efficiency is a curve so you need to be drawing power at peak of thew efficiency curve ideally. Depends how you use your PC and if you put it into sleep mode when not in use, as well. You can't go wrong with this PSU though.

    My Corsair HX650 died a few months before the 7 year warranty was up. HX650 was discontinued and Corsair offered to replace with RM650x or refund. I asked for another Seasonic-made unit but nothing was available at the price range so I went for the refund. They refuned me the cost of PSU and return postage for RMA (AU$60 to Taiwan).

    I will definitely buy Corsair again after this kind of warranty service.
