Introduction

With the AMD T-bird's you need power, lots and lots of power for that matter. We take power for granted, most people think power is power and we need nothing better and nothing more. That's just not true. We keep upgrading hardware like hard drives and ect. but we never think about how much power the power supply can handle. Enermax has a excellent line of power supplies to fit anyone's need's, especially when it comes to powering Peltier coolers, water cooling setups, and AMD T-bird's. I have a Peltier and have it running on a seperate power supply because my main power supply just can't handle it, and the rest of my hardware. Today I'm going to attempt to hook my peltier up to this Whisper Quiet Enermax power supply along with the rest of my hardware.



The Package

Below is what you get in the package when your purchase one. Well of course you get the power supply. The power supply has lots of molex connectors and they are really long so that they can reach all of your hardware if you have a Full tower or server. Notice the gold fan guards :) That adds a really nice touch. It has two 80mm fans on it, to keep the power supply cool.
