PC Power & Cooling Turbo-Cool 510: Very Loud At Full Load

The loudest power supply in our testing pool was the Turbo-Cool 510 by PC Power & Cooling. Its long warranty of 5 years is a good thing.

The graphic above shows the power supply connections and their length in centimeters. A cornucopia: like the second power supply from PC Power & Cooling, the Turbo-Cool offers 6 SATA connections. Drawback: only one floppy connector.

Features

This candidate comes from PC Power & Cooling for the 500 watt class, the Turbo-Cool 510 ATX-PFC, an actively cooled power supply unit from the up-market league. According to the manufacturer's details, the power supply unit emits a combined output of 510 watts. Two 12 volt runners belong to the standard equipment in accordance with the new ATX specifications. There are no special features which would surprise the buyer. The more demanding user will miss pluggable leads, which can lead to space problems in PC housing due to cable chaos. The Turbo-Cool 510 makes a good impression, due to its relatively compact construction, something not all that common in this performance class.

Test Results

This candidate, the Turbo-Cool 510 ATX-PFC, survived for 24 hours at maximum load without failures. The following data were extracted:

Input: 647 watts (212 volts, 3.09 amperes, cosphi 0.98)

Output: 510 watts (26 amperes/3.3 volts, 22.8 amperes/5 volts and twice 12 amperes on 12 volts, 20 watts on -5 /-12 volts, 5 volts standby)

Efficiency at full load: 78.8 percent (137 watt dissipation increases the air temperature by just under 11 Kelvin)

Noise reading at full load: 72 dB(A) in 12 centimeter gaps

In summary, the following can be said about the Turbo-Cool 510 ATX-PFC from PC Power & Cooling: Under full load the power supply unit gets very loud, but it can be taken seriously, and has quite a high degree of efficiency. Pluggable cables would be helpful for installation into smaller housing units. It should be clear to everyone that a model in the 500 watt class does not come cheap. Nevertheless, the close to 150$ price tag is not to steep, as the product is warranted to be free from defects in material and workmanship for a period of five years from the date of purchase.
