Efficiency Normal, Light & Super-Light Loads
Efficiency is high at normal loads and high enough at light loads. Lastly, with a 2% load, the PSU doesn’t exceed the 70% Intel recommendation.
Average Efficiency
The unit’s average efficiency is high.
Average PF
The APFC converter needs tuning for (way) higher power factor readings.
Average Efficiency 5VSB
The 5VSB rail is efficient.
Vampire Power
Vampire power is low at 115V but notably above 0.1W at 230V.

Hi, between FSP Vita 850w and XPG Core Reactor II 850W which one would you recommend?
The XPG is about $15 – $17 cheaper here
They have similar overall performance so I would get the one that is more affordable.
What about compared to Superflower Leadex vii Gold? It’s also about $17 – $20 more than XPG
Leadex is very good.
It’s now sold out everywhere in my region, alternative would be NZXT C850 for 230v? NZXT is $10 more than the XPG or the XPG might still be better choice?
I just got this PSU and am experiencing quite a bit of coil whine. Is this something you’ve had while performing your testing?
Thinking of either replacing my set or just living with it.
Nope if there are any coil whine issues, I mention them in the review. You should probably replace it.
