The new Toughpower Grand power supply series from Thermaltake has 80 Plus Gold certification, modular cabling system, and single +12 V rail. So far only two models have been released, 650 W and 750 W. Let’s see if the 750 W model is a good buy.
Power supplies from the Toughpower Grand series are manufactured by CWT.

The Thermaltake Toughpower Grand 750 W is 7.1” (180 mm) deep and comes with a 140 mm fan on its bottom (Thermaltake TT-1425, although the real manufacturer and model are Yen Sun Technology Corp. YD121425HB – the unexpected joke was that, instead of writing “Corp.,” the original manufacturer wrote “Copy,” making the company name to read as “Yen Sun Technology Copy”).
The Toughpower Grand 750 W comes with a Thermaltake logo on its rear that glows red when the power supply is on.
The reviewed product has a modular cabling system with eight connectors, four red for video card cables and four black for SATA and peripheral cables. Three cables are permanently attached to the power supply. The unit comes with the following cables:
- Main motherboard cable with a 20/24-pin connector, 21.3” (54 cm) long, permanently attached to the power supply
- One cable with two ATX12V connectors each that together form an EPS12V connector, 21.7” (55 cm) long, permanently attached to the power supply
- One ATX12V extension, 5.9” (15 cm) long
- One cable with one EPS12V connector, 21.7” (55 cm) long, permanently attached to the power supply
- Two cables with one six-pin connector for video cards each, 19.7” (50 cm) long, modular cabling system
- Two cables with one eight-pin connector for video cards each, 19.7” (50 cm) long, modular cabling system
- Two adapters to convert one eight-pin connector for video cards into one six-pin connector, 5.9” (15 cm long)
- Two cables with four SATA power connectors each, 19.7” (50 cm) to the first connector, 5.9” (15 cm) between connectors, modular cabling system
- One cable with four standard peripheral power connectors, 19.7” (50 cm) to the first connector, 5.9” (15 cm) between connectors, modular cabling system
- One cable with four standard peripheral power connectors and one floppy disk drive power connector, 19.7” (50 cm) to the first connector, 5.9” (15 cm) between connectors, modular cabling system
All wires are 18 AWG, which is the minimum recommended gauge, except the wires on the main motherboard cable, which are thicker (16 AWG).
The cable configuration is very good for a 750 W product, allowing you to have up to two high-end video cards without the need of adapters.
