Efficiency is Gold, something that will satisfy most users out there. Unfortunately, there is no information about its operating temperature range. We can easily assume that the max operating temperature is much lower than the 50°C that ATX recommends, or Akasa would mention it. Nevertheless, we will follow our typical testing procedure by cranking the heat inside the hot box up to 45 °C.

The PSU's protection features only include the basic ones, and Akasa, strangely enough, states that OCP is utilized, although it is meaningless in a single +12V rail PSU of such high capacity. Moving on to the unit's cooling fan, we find a medium speed, sleeved-bearing fan that will easily cope with the task since Gold efficiency leads to decreased energy dissipation.

The unit's footprint matches the standard ATX one, so there won't be any compatibility problems with a normal chassis, and the warranty is short at only two years, while the price is considered high, at least for the states, which means that the PSU will meet some serious competition. Nevertheless, that is the MSRP and the final retail price will, once the PSU hits the stores, most likely be significantly lower.

The PSU features a, according to Akasa, single +12V rail (There are, in fact, four +12V rails with a 40 A OCP trigger point) that can output almost the unit's full capacity: a clear indication that DC-DC converters are utilized for the generation of the minor rails, which are, incidentally, quite strong as well. Finally, the 5VSB rail has 3 A max current output and is, as such, a little stronger than the average.

Cables & Connectors, Power Distribution

Native Cables
ATX connector (570mm)20+4 pin
4+4 pin EPS12V/ATX12V (620mm)1
8 pin EPS12V (620mm)1
Modular Cables
6+2 pin PCIe (510mm+150mm)4
SATA (505mm+150mm+150mm+150mm)8
4 pin Molex (505mm+150mm+150mm+150mm) / FDD(+150mm)8 / 2


The native cables are few and could be fewer if Akasa attached the second EPS connector, which will not be utilized by most users, to a modular cable. There are, unfortunately, only four PCIe connectors, although the unit's capacity could easily support two more for a total of six. Strangely enough, the 4 pin connectors are many for today's standards, and we would definitely prefer some more SATA connectors instead, but eight of the latter will be enough for most systems.

All cables are long enough, and buyers won't have any problems on their behalf, even in full tower cases. The distance amongst connectors is adequate. Finally, all connectors adhere to the ATX spec and use 18AWG gauges.

The distribution of the +12V rails follows.

Power Distribution
12V1ATX, modular peripheral and SATA sockets
12V2EPS 4+4 pin
12V3top PCIe modular socket
12V4EPS 8 pin, bottom PCIe modular socket


Power distribution is not optimal since the 8 pin EPS connector shares the same rail with a PCIe socket of the modular panel. This means that an EPS connector and two PCIe connectors are mixed up. Thankfully, the OCP trigger point is set quite high (40 A), which means that there should not be any problems unless, of course, you are powering a highly overclocked graphics card set-up.
