Today's computer components are demanding more and more power in order to run at their full potential. Video cards and processors have advanced so fast in the last two years that their power requirements have barely been met by power supply manufacturers. Consumers have to make a very tough decision when choosing which power supply to trust with their new system, while keeping a close eye on the power specifications of each PSU to ensure they will get the stability they are looking for while keeping in mind their overclocking possibilities as well. The bottom line is whether you overclock or not, you need to invest in a quality power supply.
Before I get to the review, I would like to provide some background on Aerocool.

Packaging and Contents
The AeroCool 620W Zerodba PSU comes packaged in the now normal large box with a graphic and detailed appearance.
The PSU is stuffed into the box on the inside though, rather than put into a foam ‘harness’ of sorts, which may make create some problems during rough deliveries. Yet, the PSU was in a bag, like normal, to protect from scratches.
The AeroCool 620W Zerodba PSU comes with more than enough cables to power any system, all of which are sleeved.
Besides the standard internal cables, AeroCool has included three 3-pin fan cables which are perfect for those of us that can never seem to find a fan header on the motherboard where we need it. Four screws and a power cord are also included. The only thing I see missing is a manual. While this is a review sample, I would hope that the retail version of this PSU offers a short little manual to fully explain the features and show beginner PC builders how to install their PSU, although I realize most people don’t even know what a manual is…
What is 0 dBA Technology?
AeroCool’s Zerodba technology basically means the internal PSU fan only runs when it needs to. There are four different settings: Auto, 50C, 60C, and 70C. The ‘ultra-silent’ fan will run when you are within 5C of your set temperature. The auto setting keeps the fan spinning as long as the power source is running. This feature is very welcoming in the PSU market, as I’ve never seen user set options before.
A deeper look…
The method I chose to test the AeroCool 620W Zerodba is a common one. I connected the power supply to a test system and measured the voltage of the rails using a DMM. As this is one of the best ways to test one. After gathering the info for idling, I ran rounds of Prime95 and SuperPI and then measured temps again. I took three different readings and then averaged them out.
Test RigAerocool Zerodba rail readings
3.3v: 3.44 Idle, 3.44 Load
5v: 5.10 Idle, 5.10 Load
12v: 12.12 Idle, 12.10 Load
The rails on the AeroCool 620W Zerodba barely moved when under load. I checked once and then twice and then again. I even ran several other applications as well, yet the Zerodba gave me the same readings each and every time.
This is a very impressive power supply. The voltages didn't budge one bit. With the modular connections, I was expecting more fluctuation, yet all l I got was rock solid voltages on the Zerodba's rails. The power supply meets all of the criteria for all of the newest technology, it supports all of the dual video card formats as well as the dual core CPU power requirements, plus you get a little bling thrown in for free, minus flashy lights. This power supply will more than meet your needs for your system. Aero-Cool has done an amazing job on their new power supply, by creating stable rails, a nice and clean look and by adding a little innovation into the power supply market.
