Epilogue
The FSP VITA GM 1000W has high build quality, except for the terrible Yate Loon fan, which I would change ASAP with a Hong Hua one, and in general, its overall performance is not that low, staying close to other similar spec units. With some fixes, this platform could perform notably better and achieve a higher overall performance score. My main observations about the platform’s performance are listed below:
- Load regulation should be tighter on the minor rails.
- The transient response at 12V is good overall, but I spotted a “glitch” in the 180% transient load test, which needs to be fixed.
- The 3.3V rail drops low in the high-load transient tests. It has to remain above 3.2V in all cases, as in the “normal” transient load tests.
- Efficiency with a 20W load at 115V is very low for some reason. This is not the case for 230V input and the same load level.
- The average power factor readings are dead low. The APFC converter needs tuning!
- Vampire power is high at 230V.
Staying with the positive aspects of this product, it is excellent to see correctly set protection features, including overcurrent protection on all rails and conservatively set overpower protection triggering points. If fan failure protection were implemented, it would be ideal! However, only a few manufacturers have started providing this crucial protection feature, and in high-end, thus expensive, platforms.
Overall, depending on the street price, the VITA GM 1000 can be a decent choice, which needs to be notably lower than the MSRP one. FSP should also replace its fan with a higher-quality one. If it irons out the issues found, it will get way better and meet the competition eye-to-eye.
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.

- MSRP is on the high side
- Lower than 17ms hold-up time
- Loose load regulation on the minor rails
- APFC converter needs tuning for higher PF readings
- 12V rail’s voltage drops dead-low in the 180% transient load test (still, it is above the limit)
- Low efficiency at 20W with 115V input
- Mediocre transient response at 3.3V (high-loads)
hello 🙂
in the description is stated it is a “Platinum certified” PSU, but in the image and the official website you can only see “Gold certification” 🤔
FSP chose to downgrade them to Gold, from their own reasons. The official rating is Platinum
What exactly means “terrible” fan? Is it about the noice it produces or about it’s overall reliability and term of service?
build quality
Hey, thank you very much for your informative and professional reviews. I’ve found a lot of useful information on this site, and it’s clear that you know what you’re doing. I’m currently using this power supply, but I’ve also had several other ATX 3.0 / 3.1 power supplies in the past, from Corsair and Superflower.
I’ve had and still have the following problem with all of them: I hear a static high-pitched noise that drives me crazy. With some power supplies, it even hurts my ears. I have very good hearing and seem to be very sensitive to this. I’m slowly getting desperate. Either the problem lies with the wiring in my apartment, or I can’t handle this LLC switching. I’ve already swapped motherboards, tried different cables, power strips with filters—I’m at a loss. Can you recommend a power supply between 850 and 1000 watts that has good filters and produces little to no noise during operation? And yes, you’re right, the fan on that FSP is terrible 🙂
Try a be quiet, high-end one. They usually take good care of issues like coil whine.
Thanks for the tip. At the beginning of the year, I had a BeQuiet Pure Power 850, and it was absolute garbage. The fan wobbled, there was noticeable coil whine—much worse than what I’m currently dealing with—and the cables were terrible: sharp-edged and not particularly well-fitting. I remember struggling for about 30 minutes just to plug in the 24-pin motherboard cable, almost destroying the motherboard in the process. The 12V high-power cable was so stiff that I couldn’t close my big tower anymore, and when I tried to plug in the other side, the connector on the PSU itself got pushed inward. I remember it so well because I thought to myself, ‘Never again BeQuiet.
I’m not exactly rich or anything, so spending €300 on a power supply, especially when I’ve only got a 13600K in my system, is a bit too much for me. Do you maybe have another alternative recommendation?
Pure Power is the low-end from be quiet! Look typically Corsair and Super Flower are the best in this section, if you tell me that you had issues with them too, not many other brands remain to suggest. It is more like a trial and error case then.
You’re probably right; I’ve come to the same conclusion. Maybe the problem lies elsewhere, but I just can’t figure it out. Superflower has been the best in every respect so far.
Can you recommend a good, quiet, and smooth-running fan for the power supply? I believe it’s 120mm. I noticed that the connector is two-pin.
You should use a fan that cover’s the PSU’s needs, not just a random fan. Also the two pin connector, you will have to install it on the new fan.
I saw somewhere a presentation of this power supply and analysis of the interior, as Bulk Caps there was Toshin Kogyo (450V 680uF 105*C).
In your case I see nippon is it possible that you got a better sample or FSP released a revision in such a short time and all VITA GM units have caps from Nippon Chemicon?
I realize that both are Japanese capacitors, but still Chemicon is famous for being more reliable than TK.
This presentation also said: “There are Elite capacitors on the rectifier.”
Greetings and thanks for the test.
Everything is possible, unfortunately, but the fact is that “Japanese” caps don’t offer better performance. Still, they do keep their good performance longer, so for a review’s purpose, they don’t affect the overall performance significantly.
For me the main issue is the fan.
Ok, thank you for your reply.
Greetings and have a nice day.
