This is my 2nd Corsair PSU coming from a CX850m on my main rig, ive had no issues with this and works well with low noise and no issues.

I know, this PSU is not very good, not very reliable, but for now looks fine and I have no complaints..

This is was the best bed for a good PSU without going all out and gold rated.

It's a power supply and 80+ Gold rated. Not much to say here. Oh some might say it's not enough Juice for my set up. But believe me, it's way more than enough. Skylake and Pascal is very power efficient, it just boggled my mind.

Goth this on sale on newegg, pretty easy to work with being semi-modular. Just with the non-modular cables were all black. I ended up plasti-dipping the ends and they turned out pretty decent.

Gives me the watts I need, quiet, looks great in the tower.

For my PSU I grabbed a Refurbished Corsair CS650M semi modular. Its the first refurbished piece I've bought and it fired first try. Runs everything fine and first month no issues. Not loud at all either.

Quiet, efficient and reliable, this PSU is a great choice. It is modular, making for very easy cable management (not that I bothered). The one disadvantage of using this PSU is that the mesh sleeving for the 24-pin ATX power cable reveals the coloured wires, possibly ruining a black theme.

For being refurbished this was great!
