Introduction:

Power supplies are probably the most important part of your PC. Without a good source of power the rest of your system can suffer, especially when overclocking. We have looked at other power supplies in the past, most noticeably the very high end PC Power and Cooling 475W PSU, but also a more reasonably priced TT420 SS. Today we take a look at the TT420 SS's bigger brother, the TT520 SS. With the slightly higher price tag comes a TRIPLE fan design (as opposed to the dual fans on the TT420 SS), an extra 100W of power, and more connectors to support dual Athlon & Xeon boards.

Features and Specifications:

• +5V stand by 3A, the largest current in the market!
• Fully Support ALL Intel and AMD series demand
• Triple two-ball bearing fans, long life, noiseless and fastest cooling time
• High-Quality gold-coated fan cover and connectors (better conduction)
• (Tube-tide) design, Tidy your wires
• All DC output wires have 50 cm length
• Fan-speed control adjustable. (Auto, Middle, Low) (optional)
• Over voltage protection, Short circuit of on all output levels

The power supply is packed in bubble wrap and it comes with a power cable to go to the electrical outlet and some screws to mount it to the case. Also included it a 24pin-20pin ATX power adapter. This power supply was designed to support both dual Athlon & Xeon boards, so that is why there is the larger power connector, as well as a couple others that you probably wouldn't use on a regular system. There is the usual 4pin 12v connector for P4's, as well as the 6pin aux connector, an 8pin 12v connector I think is one specific to dual Xeon boards. There are ten (10) 4pin power connectors, as well as two (2) floppy connectors.

On the power supply are three globe fans. They are dual ball bearing so they have longer lifetime. The fan on the front & bottom draws air away from the CPU and the rear fan blows air out of the case. In AMD’s cooling guidelines, they suggest that this is the best for cooling. A switch on the back of the unit can control the fan speeds. The user may choose Auto, Low, or Middle. Auto is quiet and the fan speed in controlled by the power supply temperature. Low is obviously quiet all the time and middle is a little louder than most want to hear. It is nowhere near the noise level of a Delta or Vantec Tornado but it could get on some peoples nerves.
