A4000D with micro ATX power supply and ATX to A4000 motherboard adapter

There are several original A4000D power supplies. They are all big and reguire about one fourth of the space in A4000D case. To have more space inside your A4000 going for tower case is not the only way to achieve that. It is possible to free considerable amount of space by adding a less space consuming power supply.

Requirements:
Instructions:

One of the original A4000D power supplies. LITEON PE-3151-5 151.6W


Check your original A4000D power supply OUTPUT voltage amps and write them down for later compare.


Then you need to buy or build ATX to A4000 motherboard adapter. Here is one ordered all they way from Australia (I guess someone there has a good source of those exotic A4000 PSU connectors).


By reading some PSU product specs and measuring A4000D case I found out that 12,5cm wide ATX power supplies can A4000 case pretty perfectly. FORTRON/SOURCE MODEL NO: FSP200-50SNV (PF) seemed to provide higher maximum -12V and +12V OUTPUT voltage amps than the original A4000 PSU and only +5V OUTPUT is a little less (16A compared to 20A). So I decided to give it a go.


Even the old 3.5" hard drive cradle can be used in its original place and even though there are no hole drilled for a screw, the cradle has enough support with its two left side screws.


Some nice storage space under the power supply and behind it is now available.


ATX to A4000 motherboard adapter has plenty of space to be connected. See the jumper sticking out of the wires of ATX connector. If this jumper is on its place, then you can power on A4000 from rear switch of ATX power supply. If this jumper is removed, then you need to install stand by voltage switch somewhere. I like A500 style power on/power off switching and left the jumper on its place.


Even the screw holes are on the same place on A4000D case and 12,5cm wide ATX power supply. This power supply model needed some plastic cutting in northeast corner of the power cord socket.


All that free space gives some nice possibilities like adding a custom cut back panel to fill up the hole and putting some connectors in it or even fitting DF2: or some other mass storage under power supply.
