    Great price, good PSU - currently using one myself & being modular it makes things look nice & tidy (Corsair also includes a bag for the spare cables which is handy).

    Ridonkulously cheap!
    Don't need one but would consider getting this just for the future PC I'll eventually build.

  • Amazing price, Nothing really compares at this price.

  • Better fans and caps than the RM750 but no support for modern standby, so not sure how that works out once Intel's 12th Gen drops as you might have higher than expected idle power draw and slow resumption despite having an always on machine.

    • +1

      Are you positive about modern standby? There is a newer revision of RM750x (which some OZBers reported it has that feature). Also, do most people have systems ready to use modern standby on laptop?

      With their new RMx series of power supplies, Corsair uses a new mesh design (to better match their latest case designs), supports "Modern Standby" to deliver fast system wake-from-sleep times and heightened low-load efficiency, and a full 10-year warranty.

      Obviously, not ruling out this is not the latest series / revision.

      • Also, do most people have systems ready to use modern standby on laptop?

        Alder Lake should be ready to take full advantage of all the low power states as it will switch to power sipping cores at idle and near-idle/video, and that will be true for the desktop series too.

        not ruling out this is not the latest series / revision.

        I believe the second revision was 2018, so yeah, that's the concern here.

        EDIT: checked the model numbers, this is the 2018 version. The different design on the casing makes it easy to spot too.

          Alder Lake should be ready to take full advantage of all the low power states

          Are most of us willing to switch to Intel for this feature? So, buy a PSU that will work well with future Intel system, hoping Intel sort out their 10nm and 7nm woes and make a big comeback? Also, get a 750W PSU and care about modern standby? If power usage is a big concern, is desktop with modern standby the right way to go about it?

          It's good we know why this one is cheaper, because this is 2018 model.

          • @netsurfer: I mean the first meaningful use of the feature in an x86 design will be Alder Lake, but AMD will likely follow straight up with Zen 4.

            10nm+ should be highly competitive from them against Ryzen 5000 on TSMC 7nm Enhanced. Either way, you're looking at a new motherboard.

            • @jasswolf: Nah, modern standby isn't a feature that's important to desktop systems. The feature you are talking about could be big little CPU design. Basically, that and modern standby are both having mobile device features implemented to laptops and desktop PCs.

              Intel better blow Apple m1 CPU away with Alder Lake, and PCIe gen 5.0 support needs to be there (with PCIe gen 4.0 on chipset PCIe lanes at least). No point hyping up modern standby. It is a catch up so customers / we won't be impressed. Mobiles phones / tablets are doing that already.

              • @netsurfer: I am talking about big.LITTLE, but it doesn't do much without appropriate power states. Always-on computing is a huge step up in the user experience, and not because of the shorter time to resume.

    • It will probably take hardware manufacturers and Microsoft quite a while to get modern standby working well.

      Since this is a high power usage device primarily for gaming machines the feature would not be as important as for an office productivity computer which would benefit from always on.

      • The future power savings pay for the extra $9 you'd pay for the RM750 in this sale, so that's a weird argument. Gaming machines typically don't spend that much time gaming.

        As for modern standby support, Windows is ready to go, and there's no way Intel will fluff the advantages of Alder Lake that badly. It's the start of any potential comeback for them.

        • Modern Standby is more useful for laptops. Accepting voice commands when in low power state is fair enough for laptops, but do you really need that for a desktop? Furthermore, are you really going to save power this way? Instead of hibernate to disk/SSD, you keep the PC components running in low power state.

          Gaming machines typically don't spend that much time gaming

          Um… (then are they really gaming machines?) even if that's the case, at the end of the day, it is the time you actually use the PC that counts. It is active usage where more power saving can be achieved. Also, for family members not needing gaming PC, it is better to have them using low power PC (i.e. mini PC using 65W max or simply let them use laptops).

          Do bear in mind with laptops which already implemented Modern Standby, they do put the laptops in hibernate mode in hours where most people are deep asleep and return back to modern standby roughly 30-60 minutes before people wake up (to save power). You really need to be an active desktop standby user to benefit from this. Also, you need supported apps.

  • Any 850x deal?

  • I got the white one in a sale. Super quiet, no issues.

    This is probably the best price yet. So jump on it if you were waiting.

    • How much did you get the white ones for?

  • Good deal.

  • My PSU is the old version of this and it's 11 years old. Should I replace it?

    • +4

      IMHO, not if it works, why create landfill?

      • +3

        I think Bunny is asking if there is a risk of an 11 yr old psu blowing up his/her current machine and causing even more landfill.

    • +1

      Is the old one Silver or Gold rated? I'm in a similar situation, my old PSU is 11 years old and only 80 Plus (White) rated, moving to Gold would save me about $30 a year in electricity bills, so this will pay itself off in 4-5 years. So grabbed one anyway.

      • +1

        i thought I was the only one with the 11 year old PSU model

        so tempted to jump on this…………..oh dam…..wife is going to be cranky again….and its done

      • Mine's gold but PSU's lose efficiency over the years.

        • At this price, I'd still say change it.

    • Yes. PSUs degrade.

  • I heard someone just bought a SF750 psu with $191.xx. I think it's really a good deal.

  • Picked up a 550w 80 Bronze for 47 on eBay .. great little test PSU

  • For upgrading components in the future is fully modular the best one to get when building as opposed to semi modular?

    • It makes cable management easier - either one will be fine for future upgrades.

      • Modular PSUs aren't any better for cable management than semi-modular. Most semi-modular PSUs only have the critical cables attached (motherboard and CPU) while the others are removable.

        Only real advantage modular PSUs have is for high-end cases with custom cables.

  • I’ve also got a 10+ year old PSU (Corsair HX620W) & am in two minds…

    Starting to think it may be limiting my overclocking of the 6700XT (& 5600X) system? Overclocking isn’t essential though, so not sure if now is best time to get a new PSU?

    This PSU should ‘future proof’ the PC for the next 10 years right?

    Or should I wait until prices drop for the 850W models?

  • Price increased to $154.53
