Efficiency is Bronze and the maximum operating temperature at which the PSU can deliver its full power is restricted to 40°C. Definitely not the best combination, but this is a mainstream unit so our expectations have to be low. That said, we will still test the unit at up to 45°C to see if it can handle heat. Protections only include the basic ones. OCP (Over Current Protection) hasn't been included since it useless to a PSU with a single rail, but nor has OTP (Over Temperature Protection). The unit's fan is thankfully equipped with ball-bearings for an increased lifespan, and the dimensions of the unit are compact—fully compatible with the recommendations of the ATX spec. Finally, the provided warranty is long enough for this category, but its MSRP price is definitely stiff.

There is only one +12V rail. It is strong enough with 50 A max-current-output. The minor rails also have sufficient power with 120 W maximum combined power output, and the 5VSB rail puts out 2.5 A, which is typical for a contemporary mainstream PSU.

Cables & Connectors, Power Distribution

Native Cables
ATX connector (535mm)20+4 pin

6+2 pin PCIe (500mm+140mm)4

4 pin Molex (500mm+150mm+150mm) / FDD (+150mm)3 / 1


The number of connectors is satisfactory for the capacity of the PSU, but one more EPS connector would be welcome. Regarding cable lengths: Its main ATX connector should be closer to 60 cm long, and its EPS connector should be installed on a 65 cm long cable. However, current cable lengths will not be a problem in a medium-sized chassis. The distance amongst connectors is also adequate. Finally, all connectors use 18AWG wires, which is in accordance with the ATX spec.

Since this PSU features a single +12V rail, we do not have anything to comment on about its power distribution.
