Thermaltake Toughpower Grand 750W Power Supply Review

Price: $173.99


Thermaltake, founded in 1999, are now a major global supplier of computer accessories with offices worldwide.  Their product line is now extensive and includes PC enclosures, desktop and server power supplies, CPU coolers, HDD enclosures and docking stations, cables, DC cooling fans and gaming accessories.

Their power supply range is extensive from the Litepower and EVO Blue series to the Toughpower, Toughpower XT and Toughpower Grand series.

The Toughpower Grand series of power supplies is designed to meet the requirements of the extreme PC enthusiast and includes a modular cabling system, 80 Plus Gold certification and a rated operating temperature of 50°C making it “the Toughest power supply on the block”. The Thermaltake Toughpower Grand is available in only two varieties, a 650W and 750W model and this time around OCC will be having a look at the latter.

Closer Look:

The packaging of the Thermaltake Toughpower Grand 750W is predominantly satin black with coloured illustrations used to good effect. The top face of the box carries a photograph of the power supply with the Thermaltake logo in the top left hand corner and a cardboard sash giving the power supply wattage with small pictograms to illustrate the power supplies seven year warranty, eco-friendly features and 80 Plus Gold certification. The bottom of the box provides all the interesting stuff which includes the specification table, connector types and quantities, a short sentence with photograph to illustrate the main features and agency approval logos.











The front, rear and side panels carry the Thermaltake logo and Toughpower Grand trademark.



The top face of the box lifts like the page of a book and gives further information on the main features including Auto FanDelayCool, the use of high quality components and DC to DC convertors, dual ball bearing fan, AC push button and finally the inclusion of vibration absorbent gaskets.



The power supply is contained in a satin black box within the box that carries the Thermaltake Toughpower Grand trademark at its center.


Lift the lid and the user manual sits on top of the foam enclosed power supply with the captive and modular cables and a bag of Velcro cable straps stored neatly down the side. The top foam cover lifts off to reveal the black felt drawstring bag enclosed power supply.



The bag covered power supply along with full box contents which includes a black modular cable pouch, cardboard box enclosed power cord, cable ties, user manual and a small black drawstring bag whose contents will be explained latter. I neglected to show were the small black bag is stored but for your information it actually sits in a small cut-out in the foam underneath the user manual.



The packaging of the power supply is up to Thermaltake's usual high standard - it protects the unit during transit and includes a great set of accessories so let’s move on and have a closer look.
