The Real Power 550 SLI performed admirably during stress testing over the duration of a week. The unit showed extreme stability even when we overclocked and was quiet until under heavy load when the fan became audible over the other fans in the test system. The only aspect that was really missing was protective sleeves on the peripheral connector wires. Overall the power supply was well within tolerance levels throughout our testing and is worthy of the DH Silver Medal.
