Love the fully modular PSUs. Only problem I have been having is it that it seems that the motherboard cord seems a bit fragile. Had to rearrange a couple cords so it would turn on with the case closed.

Solid, fully modular and made by Seasonic. Decent price. No issues at all in the 6+ months I've had it.

I have two of these now. I think that the PSU is the most important part in the computer. Then the motherboard. You need clean power and a quality PCB for your parts to be based on.

I really don't have to do another review on this PSU. Everyone knows. Modular, clean power, SeaSonic, blah blah blah.

The only good modular PSU that doesn't cost £75+ It gives good clean power and was recommended by the pros such as JonnyGuru.

It's the best and well reviewed product! 520w with 80+ bronze that will keep my components well juiced. It has a nice flat styled cables and all of them are black. I think this can also support a single 1080 just in case i upgrade my current GPU.
