cheers, claimed price protection
Thanks bought one. Hopefully get a new GPU by the years end.
Not this year 2021 and im quite sure, i bought 6700xt red devil last week on pccasegear for 999+15 delivery, now it's 1149…
Still rocking a AX860 from 2012, voltage is stable as but I have started to wonder how long it's safe to keep a PSU for.
PSU's actually last quite a long time. It is not uncommon to see ten year warranties on PSU's from top manufacturers now.
I looked and the AX860 had a seven year warranty when released. So the manufacturer didn't anticipate any issues within at least seven years and typically warranties are shorter than the actual expected product life. I'd say you're likely good for a few more years yet. Just make sure to clean any dust out of the fan and give it enough air so it doesn't overheat.
Yeah it's always been behind a dust filter in a Cosmos S (oldest part of my build - 2009!), so no dust. I'm only concerned about it going pop and taking half the system with it but I'm trusting Seasonic made it well enough so will likely sweat it a few more years.
Same boat as you, my 2011 non-modular Corsair PSU is begging to be replaced.
I'm always worried the PSU will short my entire rig due to age..
If you upgrade you can at least get modular
If you're old PSU isn't 80+ Silver or higher, the power savings alone can be worth it.
My old PSU is 80+ "White" and moving to a Gold unit will save me about $30 a year on the loads I use. I grabbed the RM750X from that eBay sale the other day so the thing will pay itself off in 3~ years. Tempted to grab this and sell the 750 now…. lolIt's a 80 Plus Bronze lol
@Keeegs: You'll still see a 5% benefit on loads above 20%.
I should've mentioned that the rig the new PSU is going into is a 24/7 NAS, so you'll probably won't see as much of a savings unless you run the thing for long periods of time.Basically savings are very use case dependent.
Same thing as all the other v2/2018 models: this does not support modern standby, so if you plan on buying a new CPU/motherboard combo in 2022 and beyond, you will be missing out on significant power saving and always-on features that will pay for themselves over time with energy savings.
Additionally, such hybrid designs should offer far greater gaming performance in the same power budgets by being to offload background tasks to low energy cores, which in Alder Lake (Intel 12th gen) will offer Skylake-level performance at 0.5 W per core, all while only taking up the equivalent of 2 big cores on the silicon.
Why are you quoting Intel CPU if you care about efficiency lol
Alder Lake will be on Intel 10nm+, which should fall somewhere between TSMC 7nm and TSMC 5nm, except that how AMD utilises those processes is miles behind what you would even expect from a HPC design (eg. Ryzen 5000 chiplets are 50 MTr/sqmm).
Early Ice Lake (first 10nm chip) was 60 MTr/sqmm, and Alder Lake is way in advance of that, so it should be fairly competitive in terms of density, thermals, and power.
If I might ask someone so well versed in Intel, when can I expect to see consumer grade Intel CPUs with ECC RAM support?
@[Deactivated]: DDR5 seems to be leaning into a fair bit of ECC support, so I guess we'll find out in the coming 18 months? I haven't been looking into such things.
Alder Lake, needs a lot of things going right. Modern standby is the least of the concern. Will MB makers release DDR5 boards right away or we will be seeing DDR4 boards first?
The Big/Little design also needs Microsoft Windows scheduler updated to utilise it well (as Windows currently isn't designed to work with mixture of cores with different performance levels). Leaked benchmark isn't very impressive. Also, it is a big assumption that Intel finally solved the 10nm issue after all these years, yet Intel couldn't release any decent 10nm products this year so far yet.
There is so many marketing hype on it. Lastly, if you looked at already implemented modern standby laptops, you can tell it still uses deep hibernation to save more power while you are sleeping. You use a PC for its power, not how much extra % of power you could save while it is in standby mode.
If Intel cannot get their CPUs to perform well, AMD and Apple will soak up the market and modern standby (which isn't really THAT modern - it is more catch up to mobile devices) won't save Intel.

You might want to communicate this to everyone involved with Windows on ARM, because they don't seem to have gotten the memo.
You use a PC for its power, not how much extra % of power you could save while it is in standby mode.
You use a PC for its capabilities and form factor, and you don't want it whirring away in a living space wherever you can, even when it needs to be on 24/7 for performance tasks or for availability. You also want a world where we're saving as much energy usage as possible in order to minimise pollution, household energy budgets and allow for more of a transition to renewable energy.
There's absolutely nothing wrong with bringing this into the desktop arena for the same amount of silicon as you'd typically put two Intel big cores… it's actually a performance increase, especially if the scheduling is solid. In a way, this argument is similar to the whole debate about tensor cores on a gaming GPU being a waste.
If Intel cannot get their CPUs to perform well, AMD and Apple will soak up the market and modern standby (which isn't really THAT modern - it is more catch up to mobile devices) won't save Intel.
I agree, but modern standby at this point is about catching up to Qualcomm and Apple, it's not some wild tangent.
It does support Modern Standby i asked a Corsair rep, i don't know why people keep saying this even the older RM series supports it
People are claiming this because that's what Corsair claims. Live chat support agents mess this stuff up all the time.
That doesn't say anything about RMx not supporting Modern Standby it just say RM does support it which is true. Personally i've seen a corsair page/image saying RMx does support Modern Standby & i have the email from a Corsair customer service saying RMx does support it with a link to the RMx 850w PSU. I think people have just seen the old RM series flyer with Modern Standby painted all over it & jumped to conclusions
"Corsair's new RMx series of power supplies come with a new external aesthetic, an updated fan design and official support for features like Windows 10's Modern Standby."
https://overclock3d.net/reviews/power_supply/corsair_rm750x_…
Yes the 2021 series will, but this was for the 2018 series which doesn't.
No i've already asked Corsair customer support months ago they say the 2018 series is supported. I've also just asked them a second time for laughs awaiting their reply. Again
@frodoballbaggins: Yeah, nah. They 're wrong, they're probably just blindly reading the 2021 RMx spec sheet, considering it's now available in the US.
A differentiating point made when the RM line came out in 2019 was that it had modern standby over the 2018 RMx line.
And to think I paid $260 for this a couple of months ago…
2021 lineup coming up, hence the price reductions.
I just paid $199 from centrecom
ThanksOP, been looking for one.
Does bigger power capacity 850W mean it will draw higher power than the smaller 750W model when the PC is sitting idle?
No it's still only going to supply what your computer components need
Depends on where you sit on the efficiency curve. But the difference is negligible, like 1-2% on where sub 20% loads don't overlap, so 1-3W in the 150-170W draw range. Doubt you'll sit at sub 10% loads for long for it to matter.
My PC just randomly shuts down on idle… could it be my PSU? CPU and GPU temps are normal and the PSU is not even warm to the touch. I don't have another PSU to test my theory… I got the Corsair HX750i, it's about 5 years old. Any ideas?
What processor/ram are you using? Have you checked eventviewer to see the error logs?
6700K Corsair 2400 16GB. Eventviewer doesn't really show anything definitively relative.
Try replacing your cables if you've got spares. Worked for me.
Ohk never heard of that tip but I'll give it a go thanks.
I know I thought why would it be my cables, I never touch them and they're high end sleeved cables too. But I swapped them and no more black screens.
psu usually flake with high loads rather than low. could be a power saving setting somewhere.
Not power saving setting mate… thanks though.
In the bios on my x470 gigabyte, it has an option for legacy PSU compatibility. The description reads something about preventing just this sort of thing. Maybe have a look in bios?
Thank you, I'll give this a go.
Thought this was another RM750X deal just from looking at the price, dang what a deal.
I got one as an upgrade from a cheaper cooler master and it was totally worth it. This is a good price.
Got one of these put in my new pc just built by centrecom, always had corsair psu’s never had an issue, at this price it’s a solid buy.
Got this just over a year ago as a replacement under warranty for a HX650 with only a few months of its 7 year warranty period remaining. Not that I need that much power for my pc. Still a great solid PSU.
Worth the wait, thank you OP.
Just need a deal on X570 Tomahawk now.
