Does what it needs to and the packaged cables are nice. Mine in particular has some issues with coil whine, so I plan to RMA it soon.

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.

Solid power supply, would consider buying again for another low-to-midrange build like this. Only thing I wish it had was slightly longer SATA cables, but that could just be due my case's huge inner compartments.
