Tuniq Potency 550W PSU

3.3V Rail

Tuniq Potency 550W PSU

The 3.3v rail’s voltages certainly aren’t the best of the bunch with them nearly being the worse. They’re not high enough to cause any damage though so are perfectly fine.

5V Rail

Tuniq Potency 550W PSU

The voltages of the 5V rail are pretty reasonable but they fluctuate slightly when more power is needed. This is quite common.

12V Rail

Tuniq Potency 550W PSU

The 12V rail’s voltages are slightly high and fluctuate by 0.3v. The voltages from many of the other power supplies tested also seem to have high 12V rails though.

By looking at the Power Factor you can see the Tuniq has reasonable efficiency throughout states. Although they’re not the best results, they are perfectly adequate to maintain an energy efficient system.

The watt usages are relatively low compared to the other PSU’s on offer. This is completely fine as they’re nowhere near dangerous or problematic levels.

Noise

The 550 Watt Potency is very impressive when it comes to noise output. Throughout testing I couldn’t hear it at all; it was only when I got very close I could hear a very slight whisper.

Cost

The Tuniq Potency 550W will set you back $80. That’s about £55 with today’s poor exchange rate. This is a very competitive price for a 550 Watt unit and works out at just £10 per 100 watts.
