Efficiency Normal, Light & Super-Light Loads
The platform achieves high enough efficiency levels. It looks to perform best at light loads.
The average efficiency is satisfactory.
Given that this is a top-performing platform, I expected high PF readings at both voltage inputs I tried.
Average Efficiency 5VSB
The 5VSB rail is highly efficient.
Vampire power should be a bit lower at both voltage inputs I applied.

Another excellent review, Aris – thank you! It’s safe to say that I wouldn’t even consider buying a PSU without your thorough review. I do wonder though, I noticed that the unit is actually Platinum rated according to:
Perhaps this was a marketing choice by Corsair, but even so, an odd one!
I’m currently torn between the Corsair SF1000L (noise isn’t a concern as long as the fan does its job), the Thermaltake Toughpower 1000W, and the ROG-Loki. However, I’m hesitant about the ROG-Loki due to reported coil whine issues. If you could only recommend one SFX-L 1000W+ PSU, which would you choose (even if not listed)?
Thanks in advance for your insights!
It is Platinum in Cybenetics, because of the different methodology that it uses compared to 80 P.
I don’t have an Asus Loki review sample so far and this troubles me. Asus marketing in general is so so, rarely sending out review samples.
I would go for the Corsair SFX-L. Currently it is the best option, especially if you don’t care about noise at high loads.
Thank you very much Aris – I’ve gone with the SF1000L!
Glad I helped!
