Testing the 750W Tuniq PSU

Features & Specifications:

As of late there have 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 750W 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" branding or make sure that NVIDIA puts it in their list.  The only PSU from Tuniq that we can find anywhere on the SLI Zone is the Tuniq "Miniplant" 950W PSU.

The values on the label look pretty good and Tuniq is again 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 242.4W.  The combined wattage of all four +12v rails is 864W max and the -12v and +5vsb is 24.6W.  Total max output is theoretically 1131W, and the conservative 750W rating of the entire unit should be pretty accurate.  Tuniq has rated this PSU at 80 PLUS efficiency, and it should run nice and cool without any issues delivering the rated output.

  • Silent 140mm Two-Ball Fan
  • 3-year Warranty: we will replace new one when the power supply was broken within 3-years.
  • Size : 160x150x86mm

As mentioned above, one of the interesting features of the Tuniq Potency 750W PSU is the Fan Delay-Off Function.  The idea with this 2 minute fan delay is that the fan can cool down the hot components inside the PSU as there is often a rise in temperature immediately following a system shutdown.  This fan delay helps protect your PSU from this overheating.  In reality, I'm sure the PSU won't overheat as it should be able to provide adequate cooling with the heatsinks inside.  If not, this PSU will be one toasty monster.
