Antec AR-350 (350W)

This PSU is shipped together with the Antec NSK1380 system case. The super-compact dimensions of the case couldn’t but affect this power supply.

The AR-350 is manufactured by Seasonic.

Having an odd L-shaped outline, the AR-350 resembles PSUs for microBTX system cases but it is just an outward semblance. MicroBTX power supplies have completely different dimensions and designs. The protrusion in the AR-350 was made only to accommodate a 120mm fan.

In the assembled system case the fan is pressed against the back panel to exhaust the hot air.

The mains connector is located right on the NSK1380 case. The PSU connects to it with three clamps – you can see them in the foreground of the photo above.

The intake vent holes are in the back part of the PSU. The cables are there, too.

Oddly enough, the protruding “pocket” for the 120mm fan is completely blank. It means the bottom part of the fan does no useful work although it might cool the hot near-CPU space of the NSK1380 if there was another vent grid in the side of the PSU.

The PSU is very compact, even cramped, on the inside. Funnily, its component layout resembles full-size Seasonic PSUs at a reduced scale.

The PSU features active PFC and joint voltage regulation.

The AR-350 is cooled with an Adda AD1212MB-A73GL fan (a rated speed of 2500rpm). This photo shows again that the “pocket” that has been made in the PSU case in order to accommodate a 120mm fan lacks any holes.

The PSU has a max output power of 350W. It can yield 300W (25A) across its +12V power rail which is split into two “virtual” output lines.
