Roundup: 12 Gaming Power Supplies Compared

Gamers demand a lot from their computers, starting with the PSU. Therefore, almost every PSU manufacturer sells products optimized for gaming PCs. We introduce ripple and noise testing in this roundup to further improve our power supply evaluations.

Cooler Master Silent Pro Gold 700: Results

Efficiency meets 80 PLUS specifications:

Efficiency under different load profiles:

We recently tested another product from the Silent Pro Gold series, the 800 W model. It achieved very good results, and this 700 W version is not inferior to that unit in any way. It even manages to establish itself as the best finisher in this roundup's efficiency tests, living up to its 80 PLUS Gold certification.

The efficiency of the Cooler Master Silent Pro Gold 700 does not drop very much, even at low loads, and at 25 W it is still at an impressive 71%. The ripple and noise tests reveal no weaknesses; the PSU is well within the norm. All other test results are unremarkable as well. Even the noise level under high loads is good.


The Cooler Master Silent Pro Gold 700 is a PSU with very high electrical quality. It is well-made and stands out for its high efficiency.

    Corsair has a gamer series... whyd they test one of the units from the top line aimed more at enthusiasts?

  • Odd, why isn't Silverstone reviewed at all? Most of the power supplies they looked at are junk for anyone with more than one GPU and overclocking. I dumped my PC Power & Cooling 1000 Watt PSU because it couldn't handle two ATI 5870's and overclocked CPU to 4Ghz with 1600 FSB. I put in a Silverstone 1500Watt PSU and my system has been rock solid ever since.

    The article doesn't appear to measure noise from during switching and how much noise is introduced to the CPU and bus.

    Anyway, it will be a cold day in hell before anyone gets me to switch out my Silverstone 1500 Watt PSU.

    Nice tests but I came to a different conclusion. The seasonic X-750 is close to the most effiecent in the bunch and did you see that voltage ripple it looked like it was flat lining.

    For the ~$20 price difference between the Corsair 850HX and the AX850, I think I'll get the AX. It never hurts to invest in a great PSU :)

    I call BS. I could run your setup with my PC power & cooling 750w unit.
