Price Per the Watt:

Power Supply Thermaltake Toughpower Grand 750W at $173.99 = $0.23/Watt (10-2010)


The Thermaltake Toughpower Grand 750W power supply certainly looks the part and comes well packaged with a great set of accessories. The inclusion of Velcro cable wraps and the plastic snap-on cable ties should make cable management a little easier and installation of the two anti-vibration mounts may ease the noise. The build quality is on the whole of a good standard, but the cable sleeving on the captive cables is a little untidy and the stitching of the modular cable bag left a little to be desired.

The DC voltage load regulation is excellent but it is let down by what I would consider high noise/ripple levels on most of the rails, although they still met the requirements of the ATX12V V2.2 specification. It should however be noted that the measured ripple/noise levels were taken at 104% DC loading, effectively an overload, but I'm fairly certain there would be little if no difference at 100%. The efficiency of the Thermaltake Toughpower Grand 750W is up there with the best and will certainly save a few pennies on the utility bills.

The Thermaltake Toughpower Grand 750W is a capable power supply let down by a couple of what are really minor problems, but the enthusiast power supply market is very competitive and the little things make a difference. There's no reason not to buy this power supply, as it will certainly do the job, but there are equally capable power supplies with better performance for less of your hard earned money.
