    The cables make this power supply too difficult to install. The heatshrink makes the cables stick 4 inches straight from the connectors. I tried the corsair replacement cables and they are not great. Find a PSU with flat cables instead.

    Very quiet. Good build quality. Only minor complaint is that the PCI-E cables are thick making cable management difficult.

    If you dont run a corsair you run a evga. You want a quiet and reliable unit under stress well buy a Corsair. you wont regret spending the money. Dont buy a cheap rosewill some stuff you dont want to cut corner.

    After 7 months it died and had it replaced and come to find out it took my CPU with it. Corsair pretty much said tough luck. Stick to EVGA

    Dead on arrival (box slightly damaged). Turned into a 5 hour project trying to figure out why my computer wouldn’t turn on, ended up frying my SSD card on accident messing with it. Really unfortunate and will just be returning.

    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.
