The Xigmatek NRP-PC402, although basic, is a well-built unit using quality materials and all finished off with a grey metallic paint job.
Like many power supplies, the back panel has a honeycombed exhaust grill, IEC mains input and on/off switch. The front of the power supply showing the cable outlet and an extra set of exhaust outlets, which may be an unwelcome feature for some users because of their tendency to introduce warm air back into the PC case.
One side is blank and the other carries a label bearing the specification and agency approvals.
The Xigmatek NRP-PC402 uses a large 140mm cooling fan, which is unusual for a power supply in the 400W class. As such, it should help keep the unit cool and quiet.
The Xigmatek NRP-PC402 cables are hard wired, as can be seen in the photograph. Unlike many power supplies, the cable sleeving goes all the way into the unit, which makes for a more professional looking finish.
The cooling fan, manufactured by Fan Young Lin Tech Co Ltd, model number DFS132512H, is a 12V DC 3.0W brushless type. The printed circuit board is tidy and well laid out with plenty of room to allow for good airflow, and hence more efficient cooling. The heatsinks aren't very heavy for a 400W unit, so perhaps the efficiency is as good as claimed, leading to lower heat losses in the power supply. The electrolytic capacitors, at least the ones I can see, are by Teapo with a temperature rating of 105°C. The printed circuit board is marked HEC-550TE-2WX, which leads me to believe this is the same board used in the Compucase HEC-400TE Green Earth and some Netzteil power supplies.
The Xigmatek NRP-PC402 400W power supply is a well made unit with a basic set of accessories, so let's move on and have a look at the specification and features.
