With this price tag the EPM1200EWT better performs really good to achieve a decent price/performance ratio. Currently it is one of the most expensive 1200W units and receives heavy competition from other Platinum PSUs. The warranty is long enough, however we have seen similar high-end units equipped with seven years.
The unit's dimensions are normal for a 1200W unit and this applies to its weight too. For those of you wondering about the strange fan diameter this is due to a patent for the use of 140mm fans in PSUs. Yes it sounds crazy but someone actually holds this patent!

Enermax EPM1200EWT Power Specs
Max. Power25A25A30A30A30A30A30A30A2.5A0.5A
Total Max. Power1200W (1440W Peak Power)

The unit is equipped with six +12V rails which combined can deliver the PSU's total power, something very convenient since mainly the +12V rail is used in contemporary systems. The minor rails combined are restricted to 120W but you won't need more anyway. The 5VSB are kind of weak at 3A, for the category of the PSU. At least one more Ampere at this rail would be enough to make us stop complaining. Finally, the peak power of the unit is way too high at 1440W. Apparently the components used in the internals can easily handle the heat but pay attention, peak power should be applied only for short periods of time else you risk bricking your PSU. Especially at high operating temperatures.

Cables & Connectors, Power Distribution

Modular Cables
ATX connector (600mm)20+4 pin
8 pin EPS12V (650mm)1
8 pin EPS12V (600 mm) / 4 pin ATX12V (600mm) 1 / 1
6+2 pin PCIe (500mm) 8

SATA (450mm+150mm) / 4 pin Molex (150mm+150mm) 2 / 2
4 pin Molex ( 450mm+150mm+150mm+150mm) / FDD (+150mm) 8 / 2

The number of cables will cover every user/need. In total eight PCIe along with two EPS connectors can be used at the same time. Also 14 SATA along with ten peripheral connectors will power every drive and cooling fan you have installed in your system. All cables are fully sleeved of course but unfortunately they are very stiff, making cable management extra difficult. This stiffness is caused by the thicker 16AWG wires used in the 24pin ATX, PCIe and EPS connectors for decreased voltage drops. The remaining connectors use normal 18AWG wires. Regarding cable length, we have only one complaint, we would like additional 100mm at the PCIe cables in order to reach 600mm. All other cables have sufficient length and the distance among the connectors is ideal.

Since the PSU has many +12V rails we thought that it would be better if we used an illustration (courtesy of Enermax) to show you the power distribution on the modular panel.

Power distribution is exactly the same as the Platimax 1500W, so if you want to use the second EPS connector you should connect it to the sockets that are fed by 12V4 or 12V6. Otherwise you will mix the EPS connector with two PCIe ones and at full load situations OCP could be triggered causing an unwanted shutdown/restart.
