    Works great, 1000w sounds a little overkill but you never know when tech bumps up again. Only thing that I didn’t hate but not a fan of was the thick, stiff cables; and all three of the pcie cables were daisy chain 8x2. I don’t like daisy chaining power to high spec graphics cards but luckily there’s 3 pcies; but all 3 are 8x2 so your going to have a lot of insightly split ends hanging around untill you replace them or add extensions.

    Had to upgrade my power when I installed my new 3080gpu which my little 750 power supply couldn't keep up. Heck so good has me thinking about adding a 4th monitor for work.

    Coil whine

    Great but 1 HUGE flaw

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Is a great product, amazing compatibility, only flaw is that it has coil whine. Might not bother some but to others who care about quiet operation, especially when buying a 0db fan psu, it should not advertise to be silent on the fan only but then have audible coil whine. If you dont care about that its a good item.

    No, I would not recommend this to a friend

    Best 1000w PSU for the money. Works flawlessly, stays cool and runs quiet. Easy modular design and comes with more high quality cables than you’ll most likely ever need
