Thermaltake's Toughpower XT 1275W Platinum Snow Edition PSU

Ever since the 80Plus energy efficiency rating system came into play, PSU makers, in this case Thermaltake, have been in a race to see who could make the least energy-wasting PSUs.

Thermaltake has formally launched a power supply unit called Toughpower XT 1275W Platinum Snow Edition. The name does a reasonable job of saying how much power the PSU provides and how efficient it is. The wattage is, obviously enough - 1,275W - while the energy efficiency is the pretty much the best achievable today. The 80Plus Platinum rating allows for nothing less. For those who want numbers, the 1275W Platinum Snow Edition provides an efficiency of up to 94%.

The Full Bridge and LLC resonance with DC-DC module and interleaved PFC circuit designs are responsible for this, and for the high reliability of the unit. The 100% 105°C Japanese electrolytic and solid capacitors contribute much to the latter as well. “Who says PC system could not be trendy from within? Now, with the availability of Toughpower XT 1275W Platinum Snow Edition, enthusiasts could own a magnificent system with style from the interior,” the company says in its announcement.

Thermaltake's PSU has a dual +12V rail design and a 3-mode LED status indicator (S.P.T indicator for Standby/ Power good signal/ Temperature). Active PFC (Power Factor Correction) exists as well, as does 140mm dual ball bearing fan with and Smart Fan Control system that responds to PSU ambient temperature (chooses from fanless, silent and cooling modes). Finally, the company chose a modular cable system, so that owners needn't have more cables cluttering the inside of their cases than necessary. If we were to guess, only in 4-way SLI or CrossFire multi-GPU configurations will all wires have to be used. As for why the name includes the word “Snow.” the reason is clear even from just a look at the product photos: the PSU is painted white all over. The price shouldn't be different from that of the “normal” Platinum edition: $280 / 223.68 Euro.
