Pros

  • Excellent ripple suppression
  • Efficient
  • Can handle more than 400W
  • Quiet below 250W Load

Cons

  • Low quality capacitors (-2)
  • 12V voltage regulation has room for improvement (-0.5)

Final comments: The PoweRock 400W offers a lot for a unit around the $40 mark. It’s quiet, looks good, has enough cables, and is more than capable of delivering its rating in spec. We consider it to be fair competition to the Corsair VS450 and In Win IP-S400EQ3-2.

Score: 7.5/10
