    Being fully modular made my cable managent easy as ever hide. Great build quality and great certification level, so I know my pc parts are in good hands.

    Very happy with this PSU overall. Was looking for a 750W unit, but stock has been inconsistent the past 6 months so when this one became available I jumped on it. Loads of modular cables included allowing you to power 3x 8-pin PCIe graphics cards as well as up to 2x 8-pin (2x 4+4) CPU. Its a little annoying to have the pigtails on the PCIe cables and the 24 pin is very thick and stiff, but given the quality those are reasonable compromises.

    Unbelievably quiet. Most of the time I cant tell my PC is turned on between this and a liquid cooler for the PC. I have the case right next to me on top of my desk and seriously never hear it. By the time the fan is on, whatever game Im playing is more than overriding the noise.

    Was afraid of it frying my cpu but those other ppl probably put the pci e cables into the cpu. No problems so far, fan doesn’t spin most of the time. My 2nd Corsair psu.

    the psu makes a clicking noise normally when booting up but 3 weeks in for 2 days it started immediately shutting off after turning on with a double click noise but then it went back to normal. Besides that its extremely stable power wise and works extremely well for gaming.
