This second Silverstone device also earns a "Pass" from our testing efforts. It, too, survived the 12-hour endurance test without complaint, and all our measurements fell within the tolerance established in the ATX12V specification.

The efficiency rating under light load was just about 80% and increased to 83.2% at the higher load levels we tested. Bravo, Silverstone: That's how it's supposed to be!

This power supply will set you back about $130; at that price, it's a good choice.
