EVGA has been building power supply units (PSUs) for about 10 years, but when the company entered the market they did it with a challenging goal—built the very best PSU that could be built, but charge no more than what’s available.
It was a goal, an aspiration, and those who learned about it thought the quality nut CEO Andrew Han was just that—a nut. You can’t do it, or it would have been done. Except Han didn’t know it couldn’t be done, so he did it.
This week EVGA has rolled out its latest PSU and it is equally unbelievable. Why? Because for one thing, it is incredibly quiet. The 650 w version, running at full power—i.e., the fan at max, only disturbs the air with 24 dB, and the 750 w version only gets to 27 dB at full power, still be orders of magnitude quieter than a normal conversation. (Normal conversation is about 60 dB, a lawnmower is about 90 dB, and a loud rock concert is about 120 dB. In general, sounds above 85 are harmful.)

This is a modern PSU. It has a totally modular power panel, plus it offers a 12 v output—the latest level for the newest GPUs.

The EVGA SuperNOVA is 80 PLUS Gold Certified. That rating ensures that the power supply is 90% efficient or higher.
A unique radial design fan grill, compact 150 mm length and width, and 1000 high-quality Japanese capacitors.

EVGA says the fluid dynamic bearing is used for silence, reliability, and a longer life expectancy.
|AC Input||100–240 vac ~10.5a, 60/50 Hz|
|DC Output||+3.3 v||+5 v||+12 v||-12 v||+5 vsb|
|Max Output||20 A||20 A||62.5 A||0.3 A||3 A|
