    • Decent quality at a great price.
Style: MAG A550BN
This PSU might look like a cheap and crappy unit... BUT IT's not!!! The specs are there (I opened and analyzed the components.) While it is cheap, and the components are not top tier, they are of decent quality and perform up to spec even under extreme conditions. All the protections you need are there and they work correctly. All in all a decent quality power supply for a mainstream budget build. ... show more

    • Good entry-level PSU
Style: MAG A550BN
Quiet, efficient, cheap. If you're putting together a build with an older/lower power GPU, this is a great basic PSU.
