On the contrary, its performance is pretty good in almost all areas and, on top of that, it has amazingly high efficiency levels under super-light loads. This unit is also compatible with Microsoft’s new sleep states so it can reliably wake up a PC that it is equipped with a compatible mainboard, in less than five seconds.
On top of this, the RM850 has some solid performance. Voltage regulation is within 3% across the board for all rails. DC output quality is relatively good as well, staying under 40mV at full load. Even the efficiency is spot on for 80 PLUS Gold just as it is rated.
