Tuniq Potency 550W PSU review

Introduction and Specification

Up for review today is a PSU from Tuniq, a name that is more often associated with high quality air cooling for CPUs but they are now branching out into PSUs and cases. It remains to be seen if this will be a wise move but given the standard of their CPU coolers I have distinct hopes for the PSUs.

The product in question is the Tuniq Potency 550w which is a fairly standard looking non-modular PSU. The features and specification are as follows.

Features :

* 80 PLUS Certified
* SLI Certified
* Active PFC
* Support 9800 GX2
* Full Circuit Protection (OCP/UVP/OVP/SCP/OLP)
* Silent 120mm Sleeve Bearing Fan
* 3-year Warranty: we will replace new one when the power supply was broken within 3-years.
* Size: 140x150x86 mm

As we all know the PSU is one of the most important yet under-estimated components of the modern PC, it is pleasing to see that most of the nominal wattage is available for the 12V line as it should be with a modern PSU. The sharper amongst you may also have noted that the 150w from the 3.3V and 5V lines plus the 450w from the 12V lines doesn't add up to 550w so the ratings might be slightly on the conservative side which is no bad thing, I'm inclined to believe that the 12V lines have been slightly over-estimated in that both lines cannot produce 25A and still be only 450w. The only way to see how good it is is simply to test it now.
