The Thermaltake ToughPower Grand 750W PSU is an extremely impressive unit which met and exceeded 80 PLUS Gold requirements throughout the full range of our testing.
Aesthetically the Toughpower Grand rates highly with the curved edges, sexy black graphite colour with overlayed red accented stripe (shame we had to tear it to open the chassis however). It proves to be both sexy in appearance while remaining subtle enough to fit into a wide range of system builds.
On a performance level it is difficult to be unimpressed with such a fantastic set of results. Efficiency levels are very high, rating over 92% at 50 percent load. Additionally the ripple results are right up there with the class leading Corsair AX power supplies which we reviewed recently.
Internally, no corner has been cut with high quality 105c rated Japanese electroytic capacitors combined with solid state capacitors. The 140mm ball bearing YSTECH ‘flower' shaped fan is both capable of keeping the heatsinks cool and the exhausted air is always firmly within check, maximising at 9c higher than ambient. The special fan shape also helps to ensure that noise levels are kept to a minimum, even when under 100% load.
We have yet to receive firm UK pricing for the Toughpower Grand 750W however if they can manage to get the retail price around £130 then we feel they are onto a firm winner. With a full 7 year warranty it is clear they are as confident as KitGuru that the product is going to last a very long time indeed.
KitGuru says: One of the finest supplies at this specific power point that we have tested.
