Good for gaming PCs that don't break the bank. Modular system ensures there is no wasted ports. 80 Plus Gold is nice, and the size is pretty good, making installation a breeze. Only downside is the quantity of slots (4x4 pin and 4x3 pin) which favors SATA over CPU/GPU. Still its a good buy.

Does what a power supply needs to do. The modularity makes it easy to install and manage cables, making for a tidy PC. I have yet to hear any noticeable noise from it either, no coil whine or intense fan whirring.One thing I would note down is that all the SATA power connectors are right-angled, meaning if you have a drive that's flat against something you may have issues getting them to fit (cablemod may be a help here).Powers my RTX 3080 and Ryzen 9 5900x perfectly, no issues there!4/5 :)

Corsair sets a high standard when it comes to power supplies.
I bought this to replace a failing PSU that was not modular and I wanted to save on cable clutter.- The cables were an excellent length for a mid-tower and ATX board for reaching the CPU ports as well as all other critical areas on the motherboard while passing behind the case to reduce clutter.- The total number of cables was more than I required for this system however some people may need all that SATA and other leads.- It is very quiet as advertised.
Plenty of juice and it seems pretty quiet and stable so far. The modular cables are nice, but they're quite thick at each end so it can be difficult to bend them and get them how you need them to, especially if your case is like mine and doesn't have a lot of room behind where the PSU goes and where the cables would get plugged in.
Quiet. Cheap
The RM series is my go-to PSU. It's efficient, lasts forever, the fan only spins under load and it's very quiet.
Top tier brand good price and high quality
Used in a mid level build on my friend's computer. Does everything required, came with all bits needed for it's install.
