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.

Just got this unit with Toshin Kogyo LGWA 450v 680uF. It whines decently loud when i do the psu turn on test without a load. Might be a heads up for anyone which are sensitive to these whining sound.
I let it turn on for few minutes with the included jumper, nothing explodes so its non-issue for the most part.
Without load it works in burst mode which can cause such issues. Most modern PSUs have this problem I am afraid and it also has with the rest system parts.
I see. Thanks for the insight. I have one more question, how important is TVS diode on the 5VSB circuit? Most psu doesnt have it, only this VITA GM line and Nzxt c1200 (which im aware of). Or does the MOV already took care most of the input transients?
Hi,
I noticed that this unit has only 2 PCIE 8-pin slots. Is there a recommended configuration (pigtail) for a 3x8pin GPU?
Thank you
You just use both; you cannot do other wise. Or you move to a PSU offering 3x dedicated PCIe cables
Why did you mention fan being terrible yet according to noise levels its on the top of the list having lower dBA than some more premium units such as Corsair Shift. Also considering the PSU has 10 year warranty I’m sure they will replace it multiple times if it happens to die often, after 10 years well it’s time to replace PSU altogether anyway.
I don’t like its manufacturer.
Bought this psu after reading this review. My only concern is that my unit have coil whine when on idle from time to time.
Check if the coil whine is from the PSU or other parts in your system. It also has to do with the situation, for example in some game menus where FPS are unlimited, it is natural to have coil whine (from the GPU)
What about compare to hydro g pro series? Is there significant difference in term of quality and performance?
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.
