Taking A Closer Look
The main feature that separates the Topower power supply from the competition is that it features an aluminium casing. Due to the fact that aluminium conducts heat much better than steel, this helps to decrease operating temperatures. The fact that it looks stlyish is just an added bonus!
Unlike most units that feature just two PSU fans, the Topower unit boasts a whopping three clear fans! - One on the top, one on the front, and one on the back. Each of the fans are covered by shiny silver grills that complement the silver casing nicely.
The unit is compatible with both AMD and Intel processors and features the ATX12v connector that the Pentium 4 requires for stable operation. With a maximum output current of 520watt, the unit is also capable of supplying more power than your average PC user will ever require. This is both a positive and a negative, however, if you don't feel that you need the full 520watt (most people), you can always purchase a lower rated model.
Located on the back of the unit is a "Power On" rocker switch, a 115/230v power selector switch and a fan speed switch. Obviously, the lower you set your fan speed, the less noise that is produced by your power supply. However, this in turn will decrease the effectiveness of the cooling. Another interesting feature of the unit is that its AC power socket is switched, meaning that if your PC is shutdown the power socket is turned off. When this occurs, power is no longer being supplied to your peripheral devices, which could save you quite a bit of money on your electricity bills.
The power supply features a total of nine MOLEX connectors, two FDD connectors, one 24-pin ATX connector, one 8-pin connector, one 4-pin connector and a 24-20 pin ATX converter cable for those with motherboards that require more power than usual, such as the Tyan 2462 and 2468 boards. To ensure maximum airflow, Topower has bound all cables with zip ties and encased the ATX power lead in a tight nylon mesh.
For those of you that own massive full-tower cases, the power supplies' cables are all extremely long. This is both a good and bad feature, because if you own a mini-tower case you may find yourself having to deal with annoying "cable-clutter".
