Thermaltake Toughpower Grand RGB 850W Power Supply Review

When it comes to power supplies there are only a few basic form factors and the Toughpower Grand 850W is slightly smaller than most at 160mm deep and yet is still fully modular meaning that all of the power cables are removable.  A modular design is an important consideration for any PSU as it allows you to control cable management by using only the cables you need and gives you an easy opportunity to swap the cables for individually sleeved units at any time.

One of the special features was the venting of the PSU.  As you can see from the photos the chassis is fully stamped with venting located across the entire face of the fan, at the back and along the top edges of the PSU.  While I still prefer wire fan grills this method of venting is very elegant.

I had mentioned that the Toughpower Grand is fully modular and in terms of connections you’ll get a standard 24-pin main power connector and a single 8-pin for the CPU.  Three 8-pin connectors for PCI Express power and four connections for peripherals such as internal drives, fans and anything else requiring four pin Molex power.  

At the back of the PSU you’ll find the main input power connection along with a main power switch, an LED lighting button and Smart Zero Fan switch.

The internal 140mm RGB Riing fan cannot be controlled by software however you can cycle through the various color modes by pressing the RGB Lighting button and waiting for your color combination to come up.  Or, if you would rather run off all RGB lights simply press the button until the LEDs are disabled.

One of the Smart features of the Thermaltake Toughpower Grand RGB is the ability to adjust the fan speed in relation to how hard the PSU is working.  If operating load is lower than 10% the cooling fan will be disabled.  This switch disables that mode allowing the fan to spin constantly and provide additional cooling for your chassis.
