    Definitely a step up from older Corsair PSUs. They've moved from the unwieldy all-wires-in-a-single-sleeve cables to individually sleeved wires with combs. Makes for easier cable management and IMO it looks nicer. Length is 160mm and fits nicely in my Lancool 207 case which is notoriously awkward for large PSUs.

    Corsair makes great products and this is no slouch ! I purchase a 5070TI video card and my 750 power supply wouldn’t run it at all. I purchased this unit used provided cables and it fired right up. Runs all of the components of my system flawlessly. I’d highly recommend thi quality power supply.

    It works pretty well. The fan is unnoticeable, and also, if there's a Cybernetics platinum version of this PSU, because the box says Cybernetics platinum

    It powers things. I have nothing negative to say about it. There hasn't been any issues with this. I went with corsair to match the build. Rule of thumb, if it truly is Gold rating, it's just as good.

    Great PSU. Enough juice to power almost every PC build. Comes with all the cables needed to build and power your PC. Cybenetics Gold certification means that the PSU has passed rigorous testing and achieved an average power efficiency of 87% to 89%. It is a highly respected, modern alternative to the traditional 80 PLUS Gold certification.

    I’ve been using Corsair products and power supplies for years. They are very reliable and this one will likely last quite a while as well. In the event that it doesn’t, Corsair has a 10 year warranty and an excellent RMA process so you can feel safe with your purchase should any issues arise (which isn’t likely given their track record). I paired this with a 9950X3D, Corsair Titan 360 iCUE Link , 96GB DDR5 6000 CL 30, and an RTX 5070, and it handles it no problem.
