Test Results

Our load tests utilize a couple of FAST ATE active load testers and a variety of other equipment such as an oscilloscope, power conditioner, temperature probe and a power consumption meter. You can read more about our standard testing approach here.

The tests performed are based around six conceivable setups that are out there and progressively load down the PSU up to the power supply's limits or 1000W, whichever comes first. Since our test equipment's limits are greater than the Thermaltake TPG-750M, we can test it to the maximum.

The performance shown by the TPG-750M is almost pure perfection. It comes extremely close to reaching voltage regulation within 1% across the board and does so on the 12V rail. Checking the 12V rail with the oscilloscope shows very low ripple as well, reaching a maximum of 20mv under full load. Topping everything off is the excellent efficiency shown, proving that it is deserving of its 80 Plus Gold rating.

Final Thoughts

What is there to say about the Thermaltake Toughpower Grand 750W modular power supply that it doesn't say for itself? It is stunning to look at, boasts quality inside and out, and performs on a nearly flawless level. Of the top notch power supplies that we've had a look at lately, the TPG-750M outperforms them all.

There is a small price premium for the TPG-750M, but excellence rarely comes without a cost. While power supplies in the similar output range as the Toughpower Grand might cost a little less, it will be nearly impossible to find one that performs as well. At least Thermaltake packs the box full of goodies and backs your purchase for a whopping 7 full years.

If you're looking for a top notch power supply in the 700W-800W range, you're sure to hit a grand slam with Thermaltake's Toughpower Grand TPG-750M.
