Antec TRUE550 PWR W/ADJUSTABLE VOLTAG 5.25 PANEL ADJUST +3.3 +5.12V (ANTEC-TRUECONTROL550)

Adjust it: The TrueControl 550 comes with a control panel (top).In the hierarchy of computer components, the power supply--which delivers juice to the motherboard, drives, and other parts that need it--generally commands slightly more respect than the lowly floppy drive. But smart computer builders and upgraders know that a PC is only as good as the dependable power supply used to run it. For these savvy folks, Antec offers the TrueControl 550, with variable voltage outputs and fan speeds.

The shipping unit I looked at was ATX12V compliant and had a whopping 550 watts of total power, plus dedicated circuits for the 3.3- (40 amps max), 5- (24 amps), and 12-volt (24 amps) rails. Geared toward tweakers with big power needs (think multiple hard drives, optical drives, and fans), the unit has a street price of $126, about $25 more than comparably powered generic units.

But a no-name power supply doesn't offer the same quality--including a three-year warranty--or the 5.25-inch control panel, which installs in an empty drive bay. Why adjust power settings? Because even good power supplies may wander from their optimum settings, which can impact system stability. Plus, some PCs require a little extra juice. Antec recommends that you use a voltage meter, not your chip set's monitoring tools, to measure output. You can also adjust speeds of the unit's dual fans: Barely audible at lower settings, the fans are louder at higher settings but offer better overall system cooling.

The TrueControl 550 is expensive and has more juice and adjustability than the average computer builder needs (Antec also offers less expensive, nonconfigurable units). But if you're building a monster system and you're a stickler for details, this is the power supply for you.
