    Bought this psu because my cooler master masterwatt750 started going bad and causing my pc to restart while playing games and while the covid 19 has been going on I can’t get cooler master to RMA my old psu so I ordered this and it was fast shipping and the product has been working great

    I got this to put in a new gaming build with an intel i9 9900k. I especially liked the cables with ability to add only the cables needed instead of all cables hard wired to the PS. The cables had good lenghts and fit neatly in the cable management system in the NZXT H510 ATX case from Best Buy.

    It's pretty quiet, but the one it replaced had developed a terrible clicking noise, so anything quieter than a window box fan would sound pretty good by comparison. It's also vastly overpowered for my system, so I can't speak to how it performs under serious load. Nevertheless, Best Buy asked for a review, so here it is.

    Absolutely fantastic PSU. Drives my rig with no problems at all and PLENTY of cabling and power for any expansion I throw at it. Love the modular cabling. Would have liked a straight SATA cable though (only has right-angle). Intel i7-10700 2070S GPU

    So you just bought a bunch of new components... cool... now why would you go and buy any off brand, cheap power supply? Right... don't do that. Buy a Corsair PSU and know that your power you are delivering to the components is clean and reliable.
