Intro
Most people, when they are building a computer, dont really think about power supplies.
Usually, it's guys like us (modders, gamers, overclockers) think about power supplies. The one type of person
who really keep this foremost in mind are overclockers. Having
a rock solid steady power output that gives those high voltages which allows high overclocks can make the
difference between a fried cpu and one that lives to tell the tale. Today we have up on
the test bench an Enermax Noisetaker EG475AX-VE 475W.
Package
Upon recieving the FEDEX box, I gave it a quick look over and took some pictures and noticed a little bit of damage on the side. You know what is really funny is that it has fragile written on it, go figure. So after that trauma I decided to open up the case and see what kind of damage was done to the box. Upon opening I found this sight:
This left me speachless, I could hardly believe a company like MaxPoint would ship a product out without using any protection. No shipping peanuts or bubble wrap...NOTHING!!!! A few minutes passed while I collected my thoughts together. I reached inside to pull out the box and well... it looked good. As you can see below it came out unscathed and even had the plastic still around the box:
Well after that I felt it would be a good idea to continue on and open it up. Once opened I found this. Here they finally used some bubble wrap, to protect the PSU. Open opening the white box I found only a power cord, screws, and two case badges. I was vary fortunate this time that there was no damage to the Power Supply.
Specs
Complimentary features list and specs ripped from the Maxpoint website:
Features
Active PFC Function
PF Value 0.99 under condition of 230VAC/50Hz at full load.
Separate 12V rails
Independent 12V rails supply to MB/CPU and drives in order to provide stable and clean current to noise-sensitive devices, such as: CPU, add-on cards.Meet UL 240VA safety requirements
ATX 12V V1.3 compatible
Support latest P4 and Athlon 64 platforms. For P4 platforms use 865 (Springdale) & 875 (Canterwood) chipset's and even new P4 Prescott and AMD Athlon 64 or later CPU.
S-ATA connectors
Connect your system to the faster S-ATA interface for better performance.
Manual and automatic fan speed control
8cm & 9cm fans automatically controlled by thermostat plus rheostat control over 8cm fan. Enable users to keep the balance between cooling effect and acoustic noise.
Extra Power connector
Extra 4-pin power connector provides high-end graphic card with stable current.
Reliability
OCP, UVP, OVP, OLP, OTP, and SCP circuits ensure system well-guarded from any dangers. Maximize safety for your hardware and valuable data.
Copper-shielding
Effectively reduces electro-magnetic interference that might affect MB and CPU from normal operation. (Valid for models with 370W and higher total power)
Dual Fan
The best cooling method for PC system, and is strongly suggested by AMD.
Silence
Acoustic noise is successfully reduced with two fans giving more airflow in less rpm and smooth mechanical design of fan guards.
FM & FC functions
RPM signal of 8cm exhaust fan is provided; EG xxx AX-VE SFCA/FCA models allow
MB to on/off control 8cm exhaust fan.

(Note from the editor on the importance of the Active PFC Feature: AntiM recently did a review on a nice QTechnology PSU which also features this technology and did a great job describing what it is. Here it is again for your benefit.)
"Active PFC or Power Factor Correction allows for much better power efficiency, up to a 95% theoretical limit. It diminishes total harmonics and automatically adjusts for AC input. This translates into more stable voltages across the line and a lower operating cost. It's much cheaper, and more commonplace, to use the capacitive method or Passive PFC to regulate voltage. Although active PFC circuitry adds to the cost of a power supply, it will pay for its self several times over during the power supplies life span."
