Corsair SF750 Platinum Efficiency SFX Power Supply Review

Efficiency, PFC and Voltage Regulation

Voltage Regulation

Firstly looking at the voltage regulation, the Corsair SF750 gets off to an exceptionally strong start. Not only are the results across all load percentages consistent, but they are also remarkably close to the actual level. Seeing both sets of results being so strong already sets this power supply off in the right direction. It is, however, often indicative of further strong results to come!

This clearly shows that regardless of how much you ask of this power supply, it is capable of providing the ‘high-performance’ Corsair claims at a remarkable level.

Power Efficiency

For those of you unfamiliar with power efficiency ratings, Platinum is the 2nd highest efficiency rating available. As such, just from this declaration, the power supply is making it clear that in terms of power delivery, it meets an impressively high level. This is something that is more than confirmed in our own testing methodology.

While the Corsair SF750 isn’t hugely above the platinum efficiency requirement, it achieves it with a very comfortable margin. In fact, at higher levels, it almost tip-toes into Titanium levels. As such, despite its small stature, this is a huge performer in one of the most important factors of a power supply.

Power Factor Correction

While the PFC rating is a little low at 20% load, this isn’t usual. It equally isn’t surprising to see that when you start asking this power supply to work hard, it steps up it’s game to provide excellently strong results.
