There are hundreds of power supply units currently on the market ranging from the cheap to the expensive, from the beautiful to the ugly and they all come with various output ranges in classic or modular design. Only a few of them however offer special features and functions which can make them that little bit different. Today we will take a look at a unit from NorthQ which comes supplied with a remote control. A pioneering feature for a power supply unit, meaning you do not have to keep your case close to you (or even a case at all) in order to turn the system on and off. Let us have a close look at this and see how the whole package performs.

Packaging and bundle

We received one of the initial 4800-400 units, supplied in an OEM package, a simple white box. Inside the packaging, except the typical AC Power cable, we found an initial version of the manual and a small remote control. The remote control is very simple, with only two buttons on it.

The unit

The 4800-400 is very similar to the 4775-400 unit which we reviewed a while back. The unit is a grey-black metallic colour and is cooled by a massive 140mm fan. The bottom of the unit is entirely occupied by the massive fan, while the rear is perforated for the air to escape. Apart from the typical on/off switch, there also is an antenna at the rear of the unit. The side of the unit houses the sticker with the power specifications, which are identical to the 4775-400 unit as well.

The power cables of the 4800-400 are all entirely covered with black sleeving (much like the 4775-400 as well) which will make your system look much tidier. As well as the ATX/EPS 12V power cable and the 12V power connector, there are two cables with two SATA connectors each, a single 75W PCI-E power cable and two cables with three Molex connectors and a floppy connector on each. Finally there are two small cables, one for attaching the power button cable of the case and another to attach it to the power switch jumper on the keyboard.

Once again the fan is made by Yate Loon Electronics, a common occurance with the NorthQ supplies we have had in our labs. The heatsinks are quite large for a 400W unit cooled by a 140mm fan and good quality components appear to be used throughout. There is a small PCB towards the rear of the unit as well, with 8 dip switches and a small speaker, which is used to give audible notification when you are using the remote controller. The dip switches are there to adjust the frequency which the remote communicates with the unit. Of course it is unlikely that you will need to adjust this if you only have a single unit, however if you have multiple PC’s being powered by the same model this will allow you to turn them off and on individually.
