Tuniq Potency 750W PSU

2. Opening the box

TheTuniq Potency 750W retails for around $120 (including VAT), which is reasonable for the PSU in the 750Watt category.

Below you can see the retail box. Besides the obvious infrmation on it, there are two big logos: The 80Plus Bronze award, and the Nvidia SLI certification, which however is not listed at the official Nvidia website... According to the PSU's specs, you should not have any problems ysing it to power a dual VGA configuration but for a 3ple graphics cards setup you should go for something more powerful.

The Tuniq Potency 750Watt has all the cables attached to the main unit and it comes with a massive 140mm rotating fan. Tuniq has added a special feature that keeps the fan operating until a built-in detector show that the temperature inside your PC box is lower than 50degrees Celsius. This means that no matter if you have alerady powered down you PC, the PSU fan will be probably rotating for some additional minutes.

In the box you will also find a printed user manual, a power cord, several mounting screws, some zip ties and a Molex extension/splitter cable in case you need it.

The main unit is compact enough following the typical dimensions of the category. This means that you will be able to esily install it in any type of PC case except from small desktop or very basic tower designs.


The power supply has a matte black finish like the majority of the power supplies we have recently have tested in our labs. All the edges are not sharp making handling easy and safe.

The rear side of the device has a honeycomb design that keeps the PSU's internal temperature as low as possibe. The PSU's specs and ratings are also available on the sticker found on the side of the unit:

The power supply has four +12V rails with 0-18Amps output summing a total Wattage of 650W. The +5V boosts an impressive 30A, while the +3.3V rail offers 28A. Finally, the +5VSB contributes to the overall nominal Wattage by some additional 15W.

The Tuniq Potency offers a 20+4 and 4+4ATX pin power connectors, meaning that the these connectors are not bonded together. While this may be handy for older motherboards, 24-pin and 8-pin connectors would be more convenient.

Below you can see all the available power cables.

Connectors Included #

ATX 24 pin & 20 pin compatible

EPS/ATX12V 4+4 pin

PCI-E 6 pin

PCI-E 6+2 pin


4 pin Peripheral


The number of the available power connectors is typical for this category of PSUs. You will find 6 molex and 6 sata cables. The PCI-e 6pin and the 6+2 pin connectors are very useful if you are having a new graphics card. The cables are also long enough to cover the needs of a midi case.
