$60 - Had no clue what full modular, semi modular etc. meant until I was installing this guy. Easy enough to figure out but was definitely a surprise

Helps to get a branded PSU to ensure that your hard worked parts are safe in case of a power disruption.

It supplies power, and I don't think I've ever heard it. Cables are HARD though, like they're wrapped in steel

Read a JohnnyGuru review that says it is one of the best PSUs currently, plus a $15 rebate from Newegg. No complaints here.

A 550w gold certified power supply for this price? Can't beat it! The materials and build quality of this thing are top notch. I would highly recommend

You cannot go wrong with this unit. It receives high praise in professional reviews. It's performance is akin to that of the mighty SeaSonic PRIMEs. The Cables are sufficiently long for ATX towers.

It comes with plenty of zip ties and Velcro straps for cable management. Everything is packaged nicely. Nothing more I can add here.
