Specifications

All available protections are present including the rare Over Temperature Protection, which will be useful with the low maximum operating temperature of 40°C. The cooling fan is equipped with sleeve bearings so its lifespan will be not be as long as a ball bearings one, but at low RPMs it will produce less noise. Here we should stress also that for a PSU with 200mm of depth a 120mm fan looks strange. We wonder why the manufacturer didn't use a 140mm fan instead, which would operate at lower RPMs, producting less noise. Finally for merely 900W, the unit has very large footprint. Better make sure that your case supports such a long PSU before you purchase it.


There are five +12V rails present, with two having 3 Amps high max current. The max power each +12V rail can provide is relatively small for power hungry VGAs (e.g. an o/ced GTX580), but thankfully the OCP trigger point is much higher so there won't be any problems. Also the combined power that all +12V virtual rails can deliver is close enough to the max capacity, thus greatly enhancing the PSU's usability. Finally the minor rails are pretty strong with 166W max power and the same applies to the 5VSB rail which can deliver up to 4A.

Cables & Connectors, Power Distribution

As you can see, the unit is equipped with lots of connectors. The problem is that all cables are relatively short, especially the EPS and the PCIe ones, so in large cases users may face problems. Also the distance between the PCIe connectors is really short and we faced problems even while we were connecting the connectors to our test fixture, where PCIe sockets are really close to each other. Thankfully the distance between the peripheral and SATA connectors is the recommended one, by ATX spec. Finally, all connectors use the normal 18AWG gauges but we would prefer at least the native cables to have 16AWG wires.


As you can see the EPS and PCIe connectors are powered from different +12V rails. The only problem is that, in to our opinion, two EPS connectors on only one +12V rail with 25A max power (at least on paper) is too much. However this was the best option, based on the number of PCIe connectors and the available virtual rails.
