Epilogue
The FSP VITA GM 750W has good build quality if you take out the terrible Yate Loon fan, which I would replace ASAP. The PSU’s overall performance is decent, taking the lead from several similar-spec offerings, especially at 115V. Nonetheless, this platform has more potential, which FSP can exploit by tuning it more and improving performance in some areas:
- Load regulation should be tighter on the minor rails.
- The average power factor readings are dead low. The APFC converter needs tuning!
- Vampire power is high at 230V. It shouldn’t exceed 0.1W
Protection features matter the most in a power supply. FSP’s engineers did a fine job in the protection features, including overcurrent protection on all rails and conservatively set overpower protection triggering points. Only the fan failure protection is missing. However, only a few manufacturers have started providing this crucial protection feature, and in high-end, thus expensive, platforms.
If the VITA GM 750 is offered at a good street price and FSP decides to replace the fan soon, this unit will be a good choice for a not-so-power-demanding gaming system.
Before investing in a new power supply, read my Best ATX v3.x PSUs article to check all alternative PSU offerings. You help me a lot by using my affiliate links, which don’t increase the product’s price. I get a commission from Amazon every time you do it, which can make a difference for me, especially now that I am on my own, working exclusively for my media and not for someone else.

Hello Aris,
Thanks for the review.
Do you know when the next PSUs from FSP (MEGA, ADVAN) will be available ?
No clue, sorry.
Your in depth reviews of psu’s are amazing.
I hope you review the Lian Li Edge 1300 and new phanteks revolt 1200. I want one of those psu’s for my new built.
only the 750W used Toshin Kogyo caps b?
in the samples I got yes.
