Introduction

Plenty of power on hand is second nature to anyone even considering high power fans, a fistful of neon, or other high tech geek extras.  The accepted minimum wattage for a power supply has grown to 400 watts now.  A box I'm building now for something else, has four neon case fans, a cold cathode, and a Tt CoolMod Fan in addition to the normal components in a computer that need power.  This illustrates my point into the need of a strong power supply.  Today we are fortunate enough to have one of Kingwin's newest products, a 450 watt PSU of their new "Devine Power" line.  There are several notables about this PSU that set it aside other units on the market.  Before we take a closer look, we want to extend our thanks to the Kingwin folks for making this review possible.

The Unit

Two things stand up and grab your attention right off with the Kingwin unit, the paint job and the number of fans.  The pictures below showing the clean shine of the black casing really doesn't do it justice.  It looks much better up close.

     

The other biggie that gets you is the fans: All four!  The front and rear of the unit sport 80mm variable rate fans while the base shows off two 70mm jobbers.  The rear exhaust fan is a four LED fan that may or may not make some of you case modder types happy.  By the way, what's up with the Bug Bunny steamer trunk style stickers all over the place?

On the rear of the unit is a three position selector switch.  These three settings are position 1 which is 'T'urbo, position 2 being 'A'utomatic, and position 3 which is 'L'ow.  Automatic is governed by a temperature probe reading off the internal heatsink.  The Turbo setting was not exactly loud but enough to mildly annoy me (I'm turning into a crotchety old guy.)  The Automatic and Low settings were barely if at all noticeable.

Here is a snapshot of the fan speed / temperature graph.
