Testing the 550W Tuniq PSU

Features & Specifications:

As of late there has been a few companies that have branded their PSUs with "SLI Certified" logos that weren't actually certified.  We decided to see if this feature was accurate so we went over to the SLI Zone and were not able to find the Tuniq Potency 550W PSU in any list for any SLI setups.  While I don't believe that an "SLI Certified" PSU is better than one that isn't actually certified, Tuniq either needs to remove the "Certified" sticker or make sure that NVIDIA puts it in their list.  On Tuniq's product page, they state that this PSU can handle a 9800 GX2 which is almost a real SLI setup, but nowhere on the SLI Zone is it mentioned that we can find.

The values on the label look pretty good and Tuniq is quite conservative with their "Total Power" rating based on the amperage available to each rail.  Simple math says that the 3.3v and 5v rails should actually be capable of 207.5W.  The combined wattage of both +12v rails is 600W max and the -12v and +5vsb is 16.1W.  Total max output is theoretically 823.6W, and the conservative 550W rating of the entire unit should be pretty accurate.  Tuniq has rated this PSU at 80 PLUS and even it if is around 75% efficient, it should be able to fulfill the requirements on the 5v and 12v rails.  Even though we add the match to exceed 800W, Tuniq states that maximum total power is 550W and we have to treat and evaluation this PSU in this light.
