Dx PS30SWII Switching power supply - review

The additional power supply arrived yesterday and I had chance to connect it to the HF rig and try it out.

DX PS3-SWII Front Panel
Construction
The power supply is housed within a black coloured compact aluminium box which is essentially a huge heatsink. 
It measures 190 W x 69 H x 181 deep (millimetres) and weighs approximately 2.3 kg. The front panel housing all the controls and some connectors is held to the box with 4 screws.
The rear panel comprising a pair of screw terminals, a fuse, a selector switch, mains power connector and a small extract fan is similarly attached.

Watson W-30AM Power Supply

I've had this great linear power supply for a number of years now and it has served me well. Since getting higher powered rigs I've come to the conclusion that the fan noise is now unacceptable.

Supplying 10 Amps to the FT-450D whilst it was
transmitting 35 watts.

The Watson W-30AM is a bench power supply supplying 30 amps continuous (35 amps peak) at 13.8 Volts.
