$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.
