  • What's with Corsair cheaping out on pcie cables lately?

    My rm850x only came with 2, so I would have to daisy chain for a 3x8pin card, or shell out for a third dedicated cable.

    Seems this one also only has the 2.

    Albeit it's got the 12v one, if using NVIDIA 4000 series.

  • Isn't this the one that just failed on LTT Labs??

      I don't think LTT Labs have tested the Corsair SF750.

  • How much better is it than the first generation?

      Main difference is that it's ATX 3.1 compliant and PCIe 5.1 ready, so it includes a 12VHPWR cable meaning if you are using a GeForce 40 series GPU you don't have to use an adapter.

    FWIW Scorptec have this also for $250 and qualifies for free shipping to metro areas. I believe you have to pay shipping at mwave making it more expensive.

    • I'm pretty sure free shipping is only for orders over $250, so you'd have to add something else to cart. Still could work out cheaper than Mwave though.

        I ordered one last week from Scorptec at this price and got free shipping

    It's frustrating Corsair don't seem to want to restock the lower-wattage versions of this PSU, as I've been wanting one for a NAS but 750W seems like overkill.
    These things are usually happiest at ~40% of their rated power draw, right? Not that I'm very knowledge of the considerations, re: efficiency curves but with the cost of power these days there's potentially a big difference between picking 750, vs. 600 or 450W for something that's generally idle and runs 24/7 if those are most efficient around 300, 240, and 180W respectively.

    Equally frustrating, is I would have very much liked to take advantage of Scorptec's free shipping would that they had the Fractal Node 304 in stock.

      As someone who bought SF450 for a low power NAS and now has a SF750, I thought so too. The reality is at that low power levels, there is a tiny tiny difference in Efficency (i.e. <4% difference at the 20W load range) so you'd be hard pressed to calculate a meaningful dollar savings on power use over the life of the PSU.

      This new 2024 ATX 3.1 version is better than the old SF750 model, and is almost exactly on par with the SF450 in the "light load tests" section of these tests. In fact the new SF750 appears to be more efficient than the SF450 from about ~79W and up it seems.

  • 5090 is 600w itself. So we need 1000w

    • +1

      at one point 4090 was '600w' so we'll see, although i doubt itll actually be 150w more
