excellent PSU
good power and quiet. high-quality modular wiring. It's a pity that it doesn't support PCI-e 5.0

I wish if it has 3 PCIe cables
Unfortunately the power supply came with 3 - 8 pins cpu cables instead of 3 PCIe cables .. because it’s highly recommended for higher end graphics cards to use 3 separate PCIe cables to power it ..

Great PSU, great cables
I didn't expect this to come with white cables but it did! Makes my all-white PC looks great, and has sufficient power for a 3090. Note that you'll probably need to get an extra PCIe cable if you have a GPU with 3 pins though, and PSU cables are NOT universal so you'll need to make sure they're designed for the RM.

Great buy! Easy to install everything. Idiot proof :P
I honestly know nothing about building pcs nonetheless fixing one. My PSU went out after exactly 2 years of having it (Thanks CyberPower). I was extremely intimidated but last night I sat on the floor with my pc and cut the zip tied off and unplugged everything that needed to be unplugged with the old PSU and I worked on the Corsair PSU one by one till I had it all connected. Took about an hour for me mostly because I was being so careful with everything. Everything clicked in perfectly and was a breeze setting up. It even came with zip ties which was nice because I had to cut the previous ones off. I plugged it in and pushed the button and WA-LA it turned on! I've been on it all day today and it's running great. It's also a lot quieter than the one that came with my pc originally. Highly recommend! I've been using a Corsair headset for years so I knew I could trust Corsair again with this. I got the 850w for $109. Well worth the cost and I love that the wires are white which matches my pc case ;)

FUENTE DE PODER TOTALMENTE RECOMENDADA.
Excelente fuente, dudaba mucho en comprarla, pues ya es algo antiguo el modelo, pero funciona de manera impecable. Silenciosa, y con muy buena potencia para prácticamente cualquier equipo de alto rendimiento. Sin duda, recomendada al 100%.

Works as I expected it to
I replaced an aging EVGA550 into a home build. With such a mess of connections I releasd the old one but kept connectors in place the disconnecte one at a time and connecting the new on in its' place. All went well and this corrected the noisy startups I was having with the old one. The old one would make a couple of popping noises and delay the boot process. This one gets right into the boot and soundlessly as it should be. I am noticing a bit of a clicking fan noise, but haven't investigated yet; it's not that noticeable and it may be a case fan.
