      real deal is in the comments of course. i wish more people were aware of super flower branded units because they're usually at fantastic prices, not to mention the amazing quality.

        Why would you buy an ATX PSU if you needed an SFX one?

      • garetz on 23/04/2022 - 10:48

        Super flower dominated the market in the mid 90s to the early 2000s, then they fell off cause their quality suffered greatly, they were exploding and taking out the whole system left and right.

        • iseeyou1312 on 23/04/2022 - 11:04

          Super flower are an OEM, they mostly make PSUs for other brands who slap their logo on it. This same unit is rebranded as the EVGA P2 1000W, which retails for ~$500.
          But both the EVGA unit and this model have been out for a while now and have both excellent reviews and user ratings. It's rather bizarre to avoid a PSU OEM because some entirely different PSUs they made in the early 2000s were bad. You've also probably used super flower PSUs since then without even realising super flower made them.

          Someone building and/or replacing a crucial part of their system, that literally powers everything, is likely aware of the difference between ATX and SFX PSUs.

          Either way, not a reason to neg the deal.

            @Oxxy: I didn't neg the deal? I just pointed out an alternative. Obviously it's not a like-for-like comparison so negging it wouldn't have been appropriate.

            You could very easily buy a SF PSU without realising it. A lot of people are probably not even aware that small-form factor PSUs exist and how they differ from larger models.

            Plus, even if you did want a SF PSU, a 750w unit basically prevents you from a 4080 or 4090 upgrade.

        • Axelstrife on 23/04/2022 - 11:10

          O11 Mini one of the most popular cases right now uses SFX PSU's and supports Full ATX down to ITX.

            @Axelstrife: The O11 Mini got terrible reviews and is being heavily discounted to clear stock. The far more positively reviewed O11 Air mini supports ATX. Neither are good cases though, but the later is a significant improvement over the glass aquarium where PC components go to be cooked to death.

                @Axelstrife: Okay, well if you want to believe an ITX case larger than most ATX cases, but locks you into SFX PSUs, mediocre thermals, no included fans, limited air intake and a $110 USD MSRP is a great buy because a few reviewers desperate for samples mercifully gave it 4 stars, then don't let me stop you. But I'll just look at the facts. Steve from GN said it sucked, but it doesn't seem they ever published a full review.

                BOTH the O11Air Mini and the standard O11 Mini discounted to the SAME PRICE.

                That was a great deal on the Air Mini, the Mini is on sale for cheaper elsewhere. But still not worth it due to the aforementioned drawbacks.

      • iseeyou1312 on 23/04/2022 - 11:25

        A 750w psu (especially a sfx psu) won't support a 4080 either. It should be okay to do a 4070 on the reference TPD, but maybe not overclocked AIB models.

    • [Deactivated] on 23/04/2022 - 23:44

        The people buying $200 PSUs.
        Also, this PSU won't manage the likely much cheaper 4080 either, so it'll really only be for the 4070 and below.

          450 watts GPU with a very efficient 100 watts 5800X3D should still do fine. Especially if you undervolt both, you should be manage within 500 draw limit for both - which most itx guys will do.

          https://wccftech.com/amd-ryzen-7-5800x3d-cpu-undervolting-mo…

          There is also the Radeon advantage which much less powerhungry for the next gen.

            Not at all. The 3080 has transient load spikes close to 500 watts, which if the PSU can't handle (and even your standard 750w gold would struggle) the whole system shuts down. Now imagine a 450w card with the same spikes (which seems likely as the Ampere/Lovelace Turing architecture looks to be very similar) even 1000 watt PSUs might struggle.

            Right now, Nvidia is more power efficient than AMD, despite being on Samsung 8nm (which is more like TSMC 12nm). So in the low and midrange Nvidia will likely kill AMD in terms of power efficiency, it remains to be seen how they compete against the MCM design of Navi 31 and 32.

              @iseeyou1312: There are many people running 3080 successfully on a 650 watts. Loads of people are happily running thier 3090 in itx cases on 750 watts. A little undervolting is necessary. A 1000 watts is absolutely not required to run a 450 watts GPU if you dont have a 12900K overclocked.

              I dont know where you are getting your facts. Right now its AMD thats more power efficient in most scenarios where a higher end PSU is required. Read here - https://www.tomshardware.com/features/graphics-card-power-co…

              And if rumours are to be believed its only going to get worse with next gen for nvidia.
              I rest my case here.

              • iseeyou1312 on 25/04/2022 - 17:11

                @[Deactivated]: I mean if you're willing to drop the power draw or voltage, then just about any GPU can run on any PSU. I don't understand paying a price premium to not get the stock performance you just purchased, especially on something as marginal as a higher tier of PSU, but technically you're not wrong either. We'll just have to agree to disagree.

                I dont know where you are getting your facts. Right now its AMD thats more power efficient in most scenarios where a higher end PSU is required

                They're testing at 1440p, not 4k. AMD have an advantage at lower resolutions where CPU bottlenecks may occur, but Nvidia pulls ahead substantially in tests that incur only GPU bottlenecks. For instance, they're claiming the 3070 has an average of 116.6 FPS, and the 6700 XT is at 112 FPS, but in Hardware Unboxed's latest 50-game GPU review, the 3070 was 19% faster than the 6700 XT at 4k. But even then they were around 13% faster at 1440p IIRC, so the benchmarks that site is using are very inaccurate.

                Also, the 3060 Tis TDP is 200 watts, and the 6700 XT is 230 watts. Yet the 3060 Ti is using 205.5 watts and the 6700 XT is only using 215.5 watts. So at least for that card they're comparing an overclocked BIOS of Nvidia to the stock BIOS of AMD.

                AMD also aren't really competing at the high end (they don't have an answer for the 3080 Ti, 3090 and 3090 Ti) so it's also rather unfair to compare these cards to slower AMD cards, as power efficiency has diminishing returns.

                AMD are going to overclock RDNA 3 as much as they can, the same they did with RDNA 1 and RDNA 2. But this time they're going to be on TSMC 6/7nm and Nvidia will be on TSMC 4/5nm. Right now they're losing in power efficiency to a node comparable to TSMC 12nm. The MCM GPUs they make (Navi 31 and 32) can potentially beat Nvidia in power efficiency (remains to be seen), but it's not really possible to win for their monolithic cards (Navi 33 and below).

    Looks like it's back in stock at $179.

    There are 850W SFX units out there, but the SF750 is widely regarded as the best SFX PSU currently available. However, you may want to wait for more powerful SFX units to be released (with the PCIe 5.0 16 pin connector) if you're planning on buying a high end next-gen graphics card (which have been rumoured to use 450-600W). Some examples of these would be the Cooler Master V1100 and V1300 SFX Platinum which were announced in February but not yet available.

    That being said, this unit should work with basically any configuration available on the market right now - see Optimum Tech's video testing 600W SFX units running with the RTX 3080.

    Hope this helps for anyone considering picking up an SFX power supply.

      While next gen top tier GPUs may go up to 600W, it's pretty unlikely you would want one of these in a SFF build anyway.
      The next gen mid-range will probably outperform 3090Ti at 250W anyway.
      But it is useful to keep in mind I guess.
      Personally, I've been running a Ryzen 5900x and RX 5700 on an SF450 PSU for 1.5 years without issue.
      These Corsair units punch well above their weight.

        it's pretty unlikely you would want one of these in a SFF build anyway.

        Probably true for most, but it seems that more recent SFF/ITX cases coming out have 3-fan, 2.5/3 slot graphics cards specifically in mind

  • Espi on 24/04/2022 - 00:02
    +1

    You're absolutely right; working with a 450-600 watt graphics card is going to introduce a whole range of other problems for SFF builders in terms of thermals and whether the card will even physically fit in the case. Many models of the 3090 Ti (450 W) are up to 3.5 slots in width, which would rule out ITX cases such as the NR200.

    The enthusiast who is waiting to put a 1000W+ SFX power supply in their ITX build with a 450-600W graphics card knows who they are.

    The only other advantage of waiting would be that newer ATX 3.0 PSUs will probably come with native support for 12/16 pin connectors. That being said, next gen midrange cards will likely either stick to 2x8 or 3x8 pin connectors or come with an adapter for current PSUs.

    It's awesome that you've got an R9 5900X and RX 5700 working with an SF450, Corsair has really done a great job with their SFX PSU line-up.

  • grackfight420 on 24/04/2022 - 00:22

    Wondering if I should bite the bullet and grab this now, or wait for other lower-wattage PSUs to go down in price? Considering 5600x or 12600k paired with a 3060ti, and running both at stock or undervolted.

    • Espi on 24/04/2022 - 01:44
      +1

      You would definitely be able to run those components on an SF450 or SF600.

      Moving up to an SF750 Platinum will give you a bit more room for future upgrades (higher wattage, extra EPS/PCIe connector) and also remain more silent during typical use (zero RPM fan up to 300W of load). That being said, you would likely notice noise from other components much sooner. Depends whether you think these features are worth paying more for!

      As an interesting aside, I've heard that the SF600 Platinum is the only PSU from Corsair that isn't ATX 3.0 compliant (when disregarding the new PCIe 5.0 connectors). This is unconfirmed though, so make of that what you will.

    • Lonestar80 on 24/04/2022 - 11:33

      I highly recommend this over the 450 and 600. Yes, you won't need 750 watts but with your components you will run this PSU in the optimal efficiency range even under heavy load. My 5900x and 6700xt don't push the 750 platinum and it runs without fan.

      How much are you going to save over the 600? $20 perhaps for a component that you likely keep for many years. In my view not worth agonizing over.

  • Lonestar80 on 24/04/2022 - 11:25
    +1

    Fantastic PSU for SFF cases. I got this in my CoolerMaster NR200 to power a 5900x and 6700xt. The fan almost never runs in my setup and I have plenty of headroom for future CPU or GPU upgrades.

    At $179, this is a bargain for a component that you likely keep for many years. My previous ATX PSU was a Silverstone which I used for 9 years.

  • aleminium on 24/04/2022 - 13:47

    Great deal so just grabbed one! I have a SF600 with GTX3080 which has been fine (gaming/mining), but always good to have a little more headroom for future upgrades. Thanks OP!

  • MissKitty on 26/04/2022 - 11:11

    Waiting for the 4080 actual specs to see if I need the announced (but not yet released) Cooler Master V1100 and V1300.
