Efficiency is 80 Plus Gold certified, and we couldn't find any information on the operating temperature range, but this won't stop us from conducting our tests at 40 - 45°C. After all, if anything goes wrong, OTP (Over Temperature Protection) will save the day and the PSU.

According to Aerocool, the cooling fan has a 139 mm diameter, but it is actually only 135 mm across. Some companies avoid installing 14 cm fans, which is the usual size, not because of space restrictions, but due to a patent that a company holds for the use of specific diameter fans inside their PSUs! Talk about crazy patents here! Thankfully, the dimensions of the unit are compatible with the standard ATX ones, so it will easily fit into every normal chassis. Also, the PSU is only compliant with the v2.3 ATX spec, not v2.31, which is the latest ATX spec, but it has the minimum of two +12V required by the latter spec. This is not that important, since it doesn't affect the unit's overall performance. Its warranty is set at three years. We expected a longer warranty from a unit of this category. The price looks quite stiff, even by EU standards. Finally, at the time of the review, we were unable to locate this specific model in a US online store.

Two +12V rails combine to almost deliver the full power of the unit together, something normal to all good PSUs nowadays. The minor rails are strong enough for today's standards/needs, and the 5VSB rail will easily cover every need with 3.5 A maximum current output.

Four PCIe and two EPS connectors make an excellent number of connectors for the capacity of the unit, and all of them are available at the same time. Also, the length of the fixed ATX and EPS connectors is sufficient; however, we would like a little more headroom on the native PCIe cable. The same applies to the modular PCIe cables: the distance to the first connector should at least be 55 cm. Thankfully, the distance amongst all connectors is adequate and the mixed SATA/Peripheral cables may prove handy to some while troubling others. Finally, the 24 pin ATX connector is equipped with thicker gauges of AWG16 size, while all the other connectors, both native and modular, consist of AWG18 wires.

The two +12V rails handle all the connectors, so the first rail inevitably mixes both EPS connectors with the modular PCIe socket to which a cable with two PCIe connectors is connected. If you only need two PCIe connectors, you better use the native ones, or at least connect the modular cable to the bottom PCIe socket of the modular panel.
