The 12V rail’s OCP triggering points are set low and differ enough between cold and hot conditions, so everything is good here. The same goes for the over power protection’s conservatively set triggering points, which have a high enough difference between cold and hot conditions. Moreover, the minor rails have correctly set OCP triggering points. Lastly, all other essential protection features are present and work well, except the fan failure protection. Manufacturers should start implementing this protection because it is crucial!

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.
