Corsair SF1000 ATX 3.1 PCIe 5.0 Platinum Power Supply Review
Peter Donnell / 5 months ago
Efficiency
Unsurprisingly, the efficiency is excellent, as this is a platinum rated unit, but even more impressive is that it’s still pretty high even by that standard, having better efficiency than a lot of full-size ATX platinum units.
PFC (Power Factor Correction)
This is reflected in the PFC too, which scored strong throughout, but really hit its stride from 60% load upwards, with very little power factor correction, resulting in better efficiency and less waste heat generation.
Voltage Regulation
Voltage regulation is also superb, scoring just -0.72% to 1.42%, and well within the +/- 3% we want to see on a good quality power supply.
