Roundup: 12 Gaming Power Supplies Compared

Antec TP-750: Results

Efficiency meets 80 PLUS specifications:

Efficiency under different load profiles:

Having an 80 PLUS Bronze certification naturally means that the Antec TP-750 will not blow away the rest of the competition in this roundup, but at least it does not have any problems reaching the required values for the Bronze logo. The efficiency is 80% at loads all the way down to 100 W, where it starts dropping a little, though still remaining satisfactory.

The PSU performs brilliantly in the noise and ripple tests, and it is actually among the very best models in the entire roundup. The 18 mV value on the 12 V rail is particularly outstanding. In the other tests, the Antec TP-750 performs on par. The only criticism we have is a rather loud fan noise when under full load.

The Antec TP-750 is a gaming PSU with high electrical quality at a reasonable price. It naturally cannot compete with the Silver- and Gold-certified PSUs in the energy efficiency department, but we can still comfortably recommend it.

    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.
