Thermaltake  ToughPower XT 775w PSU Review

 

Conclusion

Once again Thermaltake has proved to be a worthy contender in the high-end power supply market. The Toughpower XT has everything you could want in a PSU....and then 25w more! Starting with voltage stability, the XT managed to hold good levels all the way up to its maximum output of 775w. Even during the cross-load tests the voltages stayed well within specifications showing that this unit is one of genuine power, unlike some competitors that require perfectly balanced loads in order to maintain acceptable voltages. Further reinforcing this fact was the results from the MAX-Load test that had the XT 775w running at a continuous 990w with a 50°C ambient temperature - and voltages still well within ATX spec. Simply excellent.

Ripple suppression was equally as good, which came as somewhat of a surprise considering the competitive pricing of the unit. Most manufacturers tend to save their pennies going for cheaper/fewer capacitors if they're intending to compete on pricing, but not Thermaltake with the XT. Nippon Chemicon and Teapo grace the unit along with two VRM's using solid state caps. This kept ripple on the +3.3v and +5v rails below 25mV and the +12v rail below 55mV in every single test thus ensuring the longevity of the hardware that it will be powering.

Efficiency was above expectations too. Considering that the XT 775w is 80PLUS Bronze certified I was expecting results around the low to mid 80's. But based on the test results Thermaltake really shouldn't have had any issues meeting the requirements of a Silver certification. 90% efficiency was hit at a 392w load, which will more than likely be the kind of wattage that most users of this PSU will be running at unless a seriously power hungry graphics card is used.

Finally the appearance of the unit is quite unique. I'm not 100% sure if I like the idea or looks of the integrated fan grill as I can imagine it to be quite restrictive in comparison to a wire one. However, the tough grey powdercoated finish is a refreshing change from black, and the status LED's at the side of the unit is a novel idea that will undoubtedly give users of windowed PC cases something new to look at.

Available from Yoyotech for £87 all inc, it is actually quite a steal.

The Good
- Solid 5v and 12v rails.
- Awesome ripple suppression.
- Above rated efficiency.
- Reasonably quiet
- Excellent value for money.

The Mediocre
- 3.3v output could be tighter.
- Fan grille looks quite restrictive.

The Bad
- Absolutely nowt.

The XT may have 25w more power than its 750w competitors, but does it have what it takes to impress OC3D?

Isn't the 775W version silver certified?Quote

Stefan, I've been hearing mixed things. Apparently the website says silver, but the box most definitely says bronze

Maybe they re-submitted after the first batch went out. :/Quote
