Introduction


We would like to thank Thermaltake for supplying the review sample.

Although Thermaltake states that the Toughpower Grand series is their flagship, strangely enough they decided to add three new members to the Toughpower XT series with such high-end characteristics, that easily place them on top of all Thermaltakes PSUs. The most powerful addition is the TPX-1475M which has gold efficiency and as its model number implies can deliver 1475W of power. The second model has 1375W capacity and Gold efficiency again while the last, which will be the test subject of today's review, has 1275W capacity with even higher, Platinum, efficiency. So far only Enermax managed to release a PSU with over 1200W capacity and Platinum efficiency (Platimax 1500W), as it is very difficult to retain low energy losses as the load increases.
It will be quite interesting to see if Thermaltake's unit, despite is high capacity, will manage to reach Platinum levels even inside the hotbox. However regardless of Platinum, Gold etc. we should not forget that in a PSU efficiency alone isn't the ultimate goal, since other factors like voltage regulation, ripple suppression and response to dynamic loads are even more important, so through our tests we will see how the TPX-1275M stands against the fierce competition which day by day increases, since more companies join the newly created Platinum club.

The TPX-1275M has two +12V rails with unequal power distribution (12V1: 45A, 12V2: 65A), it is equipped with eight PCIe and 16 (!) SATA connectors. It is cooled by a 14cm fan and its length is quite large at 200mm. Finally in its internals it uses cutting edge technology to achieve Platinum efficiency even at high loads, namely a full bridge topology along with an LLC resonant converter are utilized and before them an interleaved PFC shapes the current waveform. All that sounds very interesting so let's cut to the chase.
