We tested this power supply by pitting it against its older, but higher wattage sibling, the Corsair HX620W. We also threw in an Antec TruePower 550W EPS12V power supply to see how a fairly “standard” power supply design stands up. We tested the power supplies by recording their AC watt usage with a dedicated hardware watt meter which monitored total system power consumption.

Ideally, we want the power supplies to consume as little power as possible. Lower wattage levels show the efficiency of the power supplies in these various scenarios. Lower power consumption generally also leads to less heat production and less noise creation (fans don’t have to spin as fast to cool the unit).
