The Power Supply Unit (PSU) is a critical system component, however, it is often overlooked when building a system. An inferior power supply, or an underpowered one, can cause interference with other components, automatic system rebooting, drive errors and other problems than can be very hard to diagnose. An inferior PSU can also cause trouble if you expand your hardware, such as an upgrade to a new high-en Athlon XP or a Pentium 4, which may require more current than the cheap supply can provide, or the board may even need certain connections not currently available.
The Raidmax Aluminum Series PSUs are very quiet and well-built aluminum Power Supplies. They come in three ?flavors?: Gold (500W), Blue (400W), and Silver (320W) and are perfect companions for those of you who like to modify their cases, or just want add a colorful accent. Today we will be looking at the Blue 400 Watt Power Supply from Raidmax, which we purchased recently.
Out of the Blue?
As the pictures show, the 400 Watt version comes in a bright, anodized blue, and has two transparent built-in 80mm Ball Bearing fans, each of which is has a very low noise output (25db) and spin at 2200 RPM. It has six four-pin Molex connectors, two floppy drive connectors, and the three additional 12c power connectors needed for most Pentium 4 mainboards. The Molex connectors extend almost a foot and a half from the PSU, so there?s should be no problem reaching any where within your PC, even in larger full towers. It?s such a good looking PSU that it?s almost a shame to place this in a standard case where you wouldn?t normally get to see it.

The unit is constructed of a heat-flake aluminum covered crust, which allows for more heat to be transferred out of the PSU. This extends the life of the components within the unit, and gets more heat conducted out of the chassis. It also has built-in line conditioning and independent regulation of the lines, which should keep the voltage tolerances tighter than average power supplies.
There is not much that I can really say here since the process is pretty straightforward. Remove the connections from the old PSU to the drives and motherboard, and unscrew it from the back of the chassis. Then put the new unit into the same location, screw it into place, and attach the connections as necessary. Plug in the supplied power cord, and move the cutoff switch from the off to on position.
