    Best bang for your buck

    Bought this because I upgraded to a 5070ti and my factory 650w psu was not gonna cut it. Came with every cable i needed (in cool case too)and the install was extremely simple even if you're not a pc builder. Took maybe 15 minutes to swap it out and since its fully modular, you only hook up the cables you need. Its so convenient. Came with a 12vhpwr cable too so you don't need an adapter for newer gpus. Makes no noise from my experience and had a zero fan button to keep noise down even more. Love it and will highly recommend it for someone whos upgrading to a current gen gpu and needs the power.

    So Far, Things Have Been Going Well

    After over five years, my EVGA SuperNOVA 850 G3 850 Watt Gold Power Supply was showing the early signs of failure, so I opted to replace it with the NZXT C850 Gold 850 Watt 80 Plus Gold Fully Modular Low-Noise ATX 3.1 Power Supply. It had all of the power connections that I needed for my computer, and it even included a power connection that I could utilize with my ASUS TUF Gaming GeForce RTX™ 4080 SUPER 16GB GDDR6X OC Edition without needing any adapters. So far, things have been going very well, and overall, I'm very pleased with the purchase.
