The capacity of the unit has a rather strange value at 1275W. Definitely the most eye catching feature is the Platinum efficiency, which is something not to be taken lightly in a such a high wattage unit. All protection circuits are available, except OTP (Over Temperature Protection), but thankfully the unit can deliver its full power continuously even at 50°C and Platinum units have much lower internal temperatures anyway, thanks to the highly decreased power dissipation. The fan is equipped with ball bearings so its lifespan will be long and the dimensions of the unit, along with weight, classify it in the mega PSUs category. Finally the warranty is long, ensuring your piece of mind, but unfortunately the high price will lighten your wallet. As it seems the technology needed to meet the Platinum specs doesn't come cheap and the TPX-1275W uses all modern tricks to provide the highest efficiency possible (interleaved PFC, full bridge topology and an LLC resonant converter).

There are two +12V rails with mismatched power distribution. The minor rails are rated at 150W combined, a more than sufficient level of power for any contemporary system and the 5VSB have 17.5W capacity. We would prefer to see over 20W at 5VSB, from such a strong PSU, but 17.5W will easily cover most of the needs of a demanding user.

This unit has enough connectors (and power) to easily feed two high-end systems and not only one. It's the first time, as far as we can remember, that we encounter a unit with 16 SATA connectors! Also with eight PCIe connectors at your disposal four way SLI/Crossfire won't be a problem, if your budget can handle it of course. However you also have to figure out how you will utilize four VGAs!

What doesn't look so good here is the somehow short length of the EPS cables. In large cases, where this beast most likely will be installed, only 550mm of length might be a problem. Also we would like to see the 24pin ATX connector and the PCIe ones to have at least 600mm length. Finally the 24pin ATX connector uses a mix of 16, 18 and 20AWG gauges, the EPS/PCIe connectors use 16AWG wires since high current goes through them while all others connectors use the typical 18AWG wires.

Power Distribution
12V1ATX, EPS*2, Peripheral, SATA
12V26+2pin PCIe*6, 8pin PCIe*2

Power distribution is fine since the two EPS connectors draw power from a different rail than the PCIe ones. Also the 12V2 rail which feeds all PCIe can deliver more juice than the 12V1 rail, which powers less power hungry connectors in total.
