Tuniq Potency 750 W is a 80 Plus Bronze-certified power supply that can be found costing USD 100 (or only USD 70 after a mail-in rebate). The price is good, but what about performance? Let’s see.

Tuniq Potency 750 W isn’t a long power supply, being 6 19/64” (160 mm) deep, using a 135 mm fan on its bottom and featuring active PFC, of course.

No modular cabling is provided. All cables have a nylon protection, but only the one used on the main motherboard cable comes from inside the unit. All wires are 18 AWG, which is the minimum recommended gauge, with the main motherboard cable using thicker 16 AWG wires on the +12 V and +3.3 V outputs, which is always nice to see.

 This cables included are the following:

• Main motherboard cable with a 20/24-pin connector, 18 1/8” (46 cm) long.
• One cable with one EPS12V connector and one ATX12V connector, 20 7/8” (48 cm) to the EPS12V connector and 5 7/8” (15 cm) between the EPS12V and the ATX12V connectors.
• Two cables with one six-pin and one six/eight-pin power connectors for video cards each, 18 1/8” (46 cm) to the first connector and 6 1/8” (15.5 cm) between connectors.
• Two cables with three SATA power connectors each, 18 1/8” (46 cm) to the first connector, 5 7/8” (15 cm) between connectors.
• One cable with three standard peripheral power connectors, 18 1/8” (46 cm) to the first connector, 5 7/8” (15 cm) between connectors.
• One cable with three standard peripheral power connectors and one floppy disk drive power connector, 18 1/8” (46 cm) to the first connector, 5 7/8” (15 cm) between connectors.

Although the number of cables is satisfactory, here we could clearly see where the manufacturer saved money: we think that the video card power connectors should use individual cables and it would be better if this unit came with a total of at least nine SATA power connectors instead of six.
