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.
Enermax Modu 87+ 700 W: Results
Efficiency meets 80 PLUS specifications:
Efficiency under different load profiles:
The Enermax Modu 87+ runs through our tests almost without a hitch. Not only does it offer respectable manufacturing quality, but also convinces with its electrical quality. In the 80 PLUS Gold measurements it barely misses the 87% efficiency mark at 100% load, but not by more than our measurement margin of error. It was very convincing in all the other measurements, particularly by not losing as much efficiency at low loads as its competitors.
There is also a slip up with the ripple measurements. Instead of the maximum allowed 50 mV, the Modu 87+ misses this ATX specification limit with 52 mV on the 3.3 V rail. The 74 mV and 20 mV results on the 12 V and 5 V rails are exemplary, though.
Overall, the Enermax Modu 87+ is a powerful and solid PSU which meets the demands of a gaming environment. Features like running the fans for a minute after system shuts down set it apart from its competitors, and the five-year warranty is confidence-inspiring.

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
