We have come to expect clean, reliable and robust power supplies from Thermaltake and the Toughpower XT 775W certainly does not disappoint. Appearing very much like other units in the Toughpower XT series, the 775W features a compact, rugged frame, semi-modular design and includes all of the amenities of previous models such as S.P.T. status monitoring, quiet temperature/load controlled fan, 80 Plus efficiency and nVidia/ATI multi-gpu certification.
When it comes to performance in operation, the Toughpower XT 775W is simply outstanding. Measuring only a 0.01V variance in the +3.3V and +12V rails from idle to load state, and a mere 0.01V fluctuation over time, this power supply is rock solid stable and maintains its cool and quiet demeanor under load. With Active Power Factor Correction, high quality components, robust switching circuitry and status monitoring indicators, the Toughpower XT series offers true top-of-the-line function.
The only complaint I had about the 775W XT is the 6+2-pin PCI-E connector design. I found it somewhat difficult to hold the two pieces together while inserting into the video card and would like to see a clip or other attachment to lock these in place, similar to the 4+4-pin +12V CPU connection.
The Toughpower XT 775W power supply is available online in the $125 to $135 range, whereas most quality 750W power supplies, such as Thermaltake's own TR2, start around $100 and go up from there. A good number of 800W to 850W units are over $150 in cost, so the in-between 775W seems to be priced appropriately for its size.
OCIA.net awards the Thermaltake Toughpower XT 775W power supply our Gold Seal of Approval.
