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.

I know I’m late to the party, but I bought the VITA GM 750W yesterday. My unit comes with only a 300W-rated 12V‑2×6 cable. I expected a 600W cable, although I think a 450W cable would be sufficient for a 750W PSU. The 300W cable feels a bit underpowered.
Did FSP silently change the cable, or did only the review units come with the 600W-rated cable?
A 300W cable is the standard for a 750W PSU. The review unit came with a 600W set one. Both cables are rated for 600W but the setting differs.
First, thanks for the reply!
If I’m right, you’re saying the cable is capable of 600W throughput, but the sense pins are configured differently.
My problem with this whole thing is that there is no clear indication that this PSU only comes with a 300W 12V-2×6 cable. There is no mention of it on the manufacturer’s website, not even in the manual. Cybenetics and this review state it’s 600W, so it’s safe to assume it’s 600W.
The PSU can handle a GPU like the RTX 5080, but the native 12V-2×6 cable can’t. Using an adapter is the solution, which can go up to 600W, but then why do we even have the native cable? Like in the review, 600W is overkill, but a 450W one is sufficient for a unit like this; there is still plenty left for other components if it’s a safety concern.
I just feel a little scammed because the reviewer’s unit is different from the retail ones, and again, this is not stated anywhere.
normally a 750/850W unit should come with a 300W set cable and NOT higher. If you want 600W you should go with a 1050W PSU or higher. This is according to Intel’s rules.
FSP was in the past not known for silent PSUs, looks like it changed. I hope the Non-modular variants also silent?
Does it have fan-stop feature?
With Fan i can change that terrible in stack? I now its 120mm, but its 3pin or 4pin?
brother i want to ask
right now i have 650 rmx 2018 version of corsair psu
my system was 7900 gre hellhound standart clock
7800x3d standart clock
6400mhz expo ram
3 hdd 2.5 inc
1 ssd 2.5 inch
2 nvme drive
and a lot of fans like 6 fans
is this psu decent ? i am planning to get 5070 in future
this psu was very2 cheap because promotion please answer is it good?
The PSU is more the decent. If your system works ok, no need to change it.
Hello, do you think this psu can handle a 7900xtx?
depends on the CPU also
lets say a 7600x, with a 7900xt
I believe it will be ok.
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.
I’m in Indonesia and bought 1000w version. Bulk caps is Toshin Kogyo. The box said it’s Korean version. Perhaps some region in Asia using TK caps instead Nippon Chemicon to reduce price.
