Tuniq Potency 750w PSU A number of the cables connectors have extra plugs to give the Tuniq Potency a wider appeal and application. The main ATX power cable for instance is a 20+4 type. This way it can be used in an older 20 pin ATX board or a newer 24 pin board. The same is true of the PCI-E power cables. One of the two PCI-E connectors on each PCI-E rail has ability to be used for six or eight pin uses in the same way. This gives the end user the option of having two 6 pin PCI-E connectors and two 8 pin PCI-E connectors.
The Potency is not a modular unit as we have already mentioned. But 750 watts for $120 is hard to beat. The native cables however are all wrapped in black mesh with matching black shrink wrap for a very finished look. Two 6+2 pin PCI-E and two 6-pin PCI-E lines are here with a variety of other connector types. Before we go any further, here's a quick overview on what you have in the way of connectors and how long each line is. Native cables
A quick shot of one of the EZ-Grip Molex power connectors we were talking about. The EZ-Grip is the only way to go. I'm sure a number of you have had more than your fill of trying to "rock" standard connectors in or out of a port. No more of that for me.
Sleeves and matching shrink wrap cuffs for all give a very pro look.
Performance Testing the Tuniq Potency 750w power supply will be done by monitoring power output via mainboard sensors in addition to external measurement with a graphical multi-meter to ensure we are getting accurate readings. The use of the external multi-meter serves as an independent check that voltage measurements are accurate and more importantly, stable over time and under varying load conditions. Our testing will be done under idle and under variable load conditions in an 'average' real world environment. Load conditions being our doing some DVD back ups while doing some jungle fighting in Far Cry 2 for an extended sessions. Ambient room temperature during testing was 21' C.

Results and Conclusion Idle and load voltage readings for the 3.3v, 5v and 12v lines showed a maximum variance of 0.2 volts no matter what conditions we put to it. Each individual rail was checked with our graphical multi-meter and proved clean and within spec. Clean stable power is the first and foremost job of any PSU. Installation went without incident. Some of you are saying, "It's a power supply, what kind of install issues can you have?" Take it from me, the oversized PSUs out there can be a real bear in some cases. So much so that when I see a high output standard sized PSU, I can't feel happier. The lines of the Potency proved to be of sufficient length to not pose any problems in our midtower case. I don't expect problems for tower case users either unless they get crazy with their cable routing. We had plenty of connectors to ensure that 99% of users out there will have zero worries. (There's always that one person who says they have to have eight SATA hard drives.) Operation was exceptionally quiet as a power supply should be. Now, I never could get the fan to stay on after shut down but I also don't believe the unit ever got/stayed beyond 50 degrees Celsius at time of powering off. All in all, I'm very pleased with Tuniq's new Potency power supply. Gamers looking for plenty of connectors, Active PFC, NVidia SLI Certification along with a Bronze 80 Plus rating and affordable price tag need look no further. Also, don't forget the Fan Delay Off feature which is a very nice extra. Another well made and easy to recommend product from Tuniq. Pros
