Does what it needs to and the packaged cables are nice. Does make a concerning high-pitch humming noise that annoys the ever-living crap out of my sound-sensitive friend. Gotta get on that.

Can't give it more than two stars due to the misconfigured OPP and prone-to-fail fuse, which makes this unit a significant fire hazard. On top of this issue revealed in professional testing, my unit, in particular, must be unplugged for five minutes after loss of power or it won't turn back on. I know the issue lies in the PSU as it's followed me across builds with completely different equipment and components.

If you're shopping around this budget, I'd recommend you go with a Corsair CXM PSU. It's not fully modular, no, but it's much more reputably constructed.

550W 80+ Bronze PSU. That's what I got. Quiet and Modular.

Modularity is a huge convenience for me.
