1 – Toughpower Grand 850W: Presentation

The PSU (or Power Supply Unit) is a key element when you want to build a stable and robust system. Especially if you run several high-end graphics cards under GPU-intensive applications. An under sized PSU can lead to system reboot if the power required by the graphics cards is too high. That’s why, a high quality PSU is very important.

In this review, I will stress Thermaltake’s PSU to the max to see if we can rely on this product to build a robust PC.

The Toughpower Grand 850W is one of the five models of Thoughpower Grand, Thermaltake’s new line of PSUs. Toughpower Grand line includes four other models: 650W, 750W, 1050W and 1200W.

Toughpower Grand 850W comes with a semi-modular cabling system:

The modular panel has four 6-pin connectors for devices such as HDD / DVD player and supports up to six PCI-E (6+2pin) allowing to build 3-way SLI/CrossFire systems!

But not all cables are modular. The PSU has 3 hardwired cables:
- two EPS (4+4pin and 8-pin)
- one main power connector (24-pin)

The PSU is cooled by a 14cm fan that operates at a very low noise level. Thermaltake has added a new feature called FanDelayCool: the fan continues to operate 15-30 seconds after system shutdown to ensure that all components are properly cooled.
