AeroCool’s Zerodba 620W

The Aerocool Zerodba PSU

AeroCool’s Zerodba 620W power supply offers Ultra-silent operation with high performance. This unit is also a modular power supply which means you can better manage your cables by plugging in the lines you need to use. Almost all power supplies have a cable or two that you just don’t need to use and with modular power supplies, you can eliminate that lingering cable altogether. This PSU is considered ATX 12V 2.02 compliant, so you know it is compatible with today’s current platforms.

Unique Features

Zerodba: AeroCool’s Zerodba technology consists of an ultra-silent fan, with a 4-step speed switch. The ‘Auto’ setting will start rotating the fan when the system is powered on, the ’50C’ setting will start rotating the fan when the PSU temp is between 45C and 50C, the ’60C’ setting will start rotating the fan when the temp is between 55C and 65C, and the ’70C’ setting will start rotating the fan when the temp reaches above 65C.

3-pin Fan Modular Connections: This power supply ups the other modular power supplies by offering three 3-pin fan connections right on the power supply. This is a great feature for those of you who have a motherboard with limited 3-pin fan headers!
