ASUS ROG LOKI 850W Platinum SFX PSU Review

Efficiency
Efficiency is obviously important, as the better the efficiency, the less power input is required to make the required output. This unit is rated for 80 Plus Platinum and it hit that mark very well, especially at 20-40% loads where it actually sits closer to the Titanium rating, but always stays above 90% throughout all loads, which is exceptionally good.
The PFC is excellent too, hitting a sweet spot at around 60-80% load and this is going to result in less heat being generated by the PFC hardware in your most common gaming-type load scenarios too.

Voltage Regulation
Voltage regulation is excellent on the 12v rail (split over 3 rails on our load tester, but it is in fact a single rail on the PSU), and on the vital 3.3v and 5vsb rails it has some of the most accurate readouts I’ve seen to date, very stable, very consistent.
