Specifications

Efficiency is Platinum, currently the highest efficiency certification available, with Titanium waiting around the corner. The unit is also compatible with Intel's new sleep states Haswell introduced and features a semi-modular cabling design and a maximum operating temperature of 50°C, which complies with the ATX specification. The cooling fan uses a Hysint bearing, an upgraded type of the sleeved bearing with a longer lifetime and less noise output than ball-bearings.

The P700 has is small enough since it is only 5 mm longer than normal, and its weight is pretty standard. Xigmatek lists it as ATX v.2.31 compliant, though we think it could easily meet the newer ATX v.2.4 requirements. With only three years, its warranty is on the low side, while its MSRP is too high, which will most likely cripple its price/performance ratio.


There are two +12V rails, which, combined, can deliver the full capacity of the PSU; however, the OCP is set rather low, and our tests couldn't squeeze more than 670 W out of the +12V rail during the CL2 test (maximum load at +12V and minimum on the other rails) without triggering it. The minor rails have enough power for every modern system that can be fully supported by a mid-capacity PSU, which is also true for the 5VSB rail.

Cables & Connectors, Power Distribution

There are enough connectors for the 700 W this PSU can deliver, but we have a few complaints when it comes to cable length. The main ATX cable should at least be 50 mm longer, and the length of the EPS cables might lead to problems in larger cases. Xigmatek should also make the second EPS cable modular since very few users will use both. The length of the modular cables should suffice in most instances, and the distance between connectors is enough, though some would prefer the SATA connectors to be a bit closer to one another. All three native cables use thicker 16AWG gauges, with the modular cables utilizing normal 18AWG gauges.


Power distribution isn't optimal and can be described as pretty bad since both EPS connectors are fed by the same rail taking care of the PCIe connectors, which can lead to OCP triggering and unwanted shutdowns at full load. Both PCIe sockets on the modular PCB are also only fed by four +12V wires while all four peripheral sockets are powered by two +12V wires - Xigmatek was apparently short on cables.
