About two years ago we started seeing a push towards 80 PLUS Platinum rated power supplies. At the start these were limited to power supplies capable of 1000W or less. Those who were seeking high efficiency with high wattage units were just out of luck until the last six to eight months.

We've seen a recent surge in the number of units capable of high efficiency above 1000W and today we taking a look at one from Thermaltake.

The power supply in question today is the Thermaltake Toughpower XT Platinum 1275W. Launched back in June, the Toughpower XT Platinum 1275W comes in two colors; standard black and Snow Edition for those seeking a white power supply.

Along with the two colors comes 80 PLUS Platinum efficiency and a ton of power spread across two rails to power up to four GPUs.

Everything sounds great for enthusiasts so let's dig into the specs and see how things fair.

Specifications, Availability and Pricing


I/O specifications look very good for the Toughpower XT Platinum 1275 power supply. The majority of the power is supplies via the two 12V rails. 12V1 is rated for 45A while 12V2 is rated for 65A. Unfortunately Thermaltake doesn't list a combined maximum output for the Toughpower XT Platinum 1275. Both the 3.3V and 5V rails are rated for 25A each with a combined maximum output of 150W. The power supply also features a rather strong 4A 5VSB rail for 20W of power when on standby.


Thermaltake almost scores a solid list of checks for the feature summary. We were quite surprised when Thermaltake informed us that while the power supply does feature SCP, OVP, OCP and OPP, there is no over temperature protection included in the unit. The power supply is however rated for 100% continuous output at 50C and can handle high temperatures. The Toughpower XT Platinum 1275W power supply features both native and modular cabling, all of which is fully sleeved. It is rated for 80 PLUS Platinum efficiency.

Thermaltake has an MSRP of $339.99 on the Toughpower XT Platinum 1275W power supply. That might seem a bit steep for some, but some quick shopping will yield much better prices. Currently, MWave has the power supply in stock for $259.99 plus shipping which will cost around $10 depending on where it is shipping to.

This makes it much more competitively priced and better priced than many 80 PLUS Gold rated units. Thermaltake backs the Toughpower XT Platinum 1275W with a fantastic seven year warranty.
