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.
Chieftec BPS-750C
After an outstanding performance in our 400 W PSU roundup, we were particularly anxious to test a gaming PSU from Chieftec. The manufacturer sent us a power supply from its Nitro series, this time with a power rating of 750 W.
It is 80 PLUS Bronze-certified, sports impressive manufacturing quality, and the two +12 V rails can each handle loads of up to 30 A.
The price of around $120 is not low enough to be this stingy with included connectors compared to the competition, however. The two CPU and four PCIe connectors are suitable for gaming, but the BPS-750C lags behind with just four Molex and six SATA connectors. Most cables are modular and of sufficient length.

xxsk8er101xx Because it failed a few of the tests.Reply
FLanighanWhy not Corsair? I jizz at my tx850w -
p1n3apqlexpr3ss Corsair has a gamer series... whyd they test one of the units from the top line aimed more at enthusiasts?Reply -
V8VENOM 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.Reply
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. -

JamesSneed 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.Reply -
boiler1990 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 :)Reply -

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

random1283 agreed no reccomendation for an x series seasonic, you guys must be mssing something, every other review of the x series said that they are simply amazing much better then any nxzt or anything.Reply
