The front shows the power plug and switch. Note that the back is almost completely unobstructed for air flow – the grid covers the full back.


The back shows the power ports for the various cables:


The power ports light up when connected:

The plugs are held in place by screwing the plugs into the ports:


The motherboard plugs can handle all current ATX power schemes:


The 150 mm cooling fan pretty much fills up the case:


When powered up, there are four LEDs that illuminate the blades:


Opening the top shows the hefty components to deliver the goods:


In use, I found it very quiet, most likely because I do not have a system that can stress this power supply to its max output – the fan barely ticked over. The fan monitors temps so as the load increases, the fan will speed up – even under stress (such as it was), the fan was not noticeable.


Kingwin’s’s Mach 1 1000 Watt Power Supply appears to be a sound addition for those power hungry PCs that are loaded with extras.

Thanks again to Kingwin for sending this our way – a nice unit!
