Efficiency is Gold and the unit can deliver its full power continuously even at 50°C, something not to be taken lightly since we are talking about a 1400 W monster here. Moreover, all available protection features are present in this PSU, including the rare OTP (Over Temperature Protection), which is always nice to see.
The 140 mm cooling fan can reach pretty high RPMs, at least according to Thermaltake, something that is not beneficial to noise output, but most likely the fan controller will keep its speed low, at least in most cases. Regarding the unit's footprint, this is very large since the length reaches 200 mm! Nevertheless, this is something expected in such a high-capacity PSU. Finally, the warranty is very long at 7 years, while the price looks highly intimidating at $370.

There are two +12 V rails with uneven power distribution. The first can deliver up to 50 A, while the second has 20 A more capacity. The minor rails are pretty strong too, with 150 W max combined power. Finally, the 5VSB rail can deliver up to 4 A, a sufficient power level considering the unit's total capacity.

There are numerous connectors available including eight PCIe, two EPS, six peripheral, and 16 SATA! The only problem is that the main ATX cable and especially the two native EPS ones are too short at 520 mm. Ideally, the ATX cable should have 550-600 mm in length and the EPS ones over 600 mm. As you probably know, such a beastly PSU will most likely be installed in a full tower case, so for proper cable management it will need long ATX and EPS cables. Thankfully, the distance between connectors, in cables that have more than one, is ideal at 150 mm. Regarding gauge size, the 24-pin ATX connector uses a mixture of 16, 18, and 20 AWG wires; the EPS/PCIe connectors use 16 AWG wires since high current passes through them, while all other connectors use the standard for desktop PSUs, 18 AWG gauges.

Power Distribution

Power distribution is good since the EPS connectors are separate from the PCIe ones. Also, the latter are fed from a much more powerful rail, since their number is quite large.
