FSP VITA GM 750W ATX v3.1 PSU Review

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.

 

 

Pros:
  • Delivered full power at 46°C
  • Silent operation
  • ATX v3.1 and PCIe 5.1 ready
  • Efficient platform
  • Correctly set protection features
  • Good transient response (normal loads)
  • 12V rail keeps its voltage high in the ATX v3.1 transient load tests
  • Within 1% load regulation at 12V
  • Good ripple suppression
  • Low inrush currents
  • Efficient 5VSB rail
  • Alternative Low Power Mode (ALPM) compatible
  • Good build quality (except for the fan)
  • Fully modular
  • Enough cables and connectors, including a high-power one (12+4 pin, 600W)
  • Long enough distance (150-155mm) between the SATA and half of the 4-pin Molex connectors
Cons:
  • MSRP is on the high side
  • APFC converter needs tuning for higher PF readings
  • Loose load regulation on the minor rails
  • Below 70% (69.19%) efficiency with a 2% load
  • Lower than 16ms power ok signal’s hold-up time

  1. 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.
