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 ..

I love that it's modular
This power supply is super nice and I love the fact that it's modular. It comes with a ton of extra cables and was super easy to install. I never realized that the other power supply units that I worked with were not modular and they all just had a wiring harness hanging out the back. It's definitely nice being able to customize what you want out of it that way you don't have a million extra wires hanging out. It was instantly compatible with my build and functions as should. I'll be buying another one for my girlfriend's computer shortly.

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.

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.
