ENERMAX ULTRA COOL EG451P-VE 450w Power Supply

Features

Aside from the great inner workings of the power supply itself.  The number of additional features is where this power supply really outshines the competition.  I'm sure that I could sit here all day and ramble on about every minute detail of this power supply.  But, I decided to spare you the agony.  Here are a few features that I felt that really jumped out at me and I felt that I needed to touch on:

  • Enermax power supplies feature a clear plastic fans which allows you to actually see the high quality bearings.  A lot of other power supplies use shoddier sleeve type bearing fans that fail and seize much sooner. 

  • High quality chrome fan grills are used to improve airflow much better than the normal "punched out" air notches on other power supplies.

  • Thermally controlled "Super Noise Killer" feature which increases and decreases the fan speed based on the operating temperatures.

  • Motherboard fan monitoring header for use with programs such as Motherboard Monitor to keep tabs on power supply fan speed.

  • Dual fans (high quality dual ball bearing 92mm intake and 80mm exhaust fans)

  • Plenty of power leads:  Eight four pin Molex connectors and one FDD connector

  • Power leads are 1 meter (30") in lentgh to accommodate almost any type of case.

  • External ON/OFF switch & Toggle b/w 115v and 230v.

  • Exceeds Intel and AMD requirements.

  • Long life. Estimated 100,000 MTBF based on 70% constant load.

  • Meets Intel v2.01 & v2.03 ATX form factor.

In my last review I gave an ATX power pin layout for you to have for reference.  This time I took it a little further and added color to the pins to make it clearer.

All-in-all pretty damned impressive in my opinion!  Now, how easy was the installation?
