X-Power 400W ATX PSU Power Supply Unit ATX-400TD 20/24-Pin

For help in identifying your power supply connectors please use the following guide:

               20-pin ATX Connector – 2 rows of 10 pins that connect straight to the motherboard.

                             24-pin ATX - 2 Connector - Same as a 20 Pin Connector but with an extra 4 pins - 2 Rows of 12 pins that connect straight to

                             the motherboard.

                             12-pin AT Connectors – 2 separate plugs of 6 pins that plug into a 12 pin socket on the motherboard

                     4 Pin Molex P4 Connector – A square plug that connects direct to the motherboard, used specifically for P4 motherboards -

                               Intergrated directly into the pwer connector for an ATX-2 (Normally 2 yellow wires and 2 black wires).

                     6-pin Aux Connector – 1 row of 6 pins that normally connects directly to your motherboard (Normally 3 black wires, 2

                              orange wires and 1 red wire.  Dell Power supply supplies sometimes have 3 back and 3 blue/white wires instead)

                 4 Pin Molex Connectors – These are for supplying power to your Hard Drives and Optical Drives (CD/DVD) and occasionally

                              to some motherboards and graphic cards for additional power.  (Normally 2 red, 4 black and 2 yellow wires and the last

                              Molex connector on the circuit will only  1 red, 2 black and 1 yellow wire)  Some Dell power supplies have short stubby

                              Molexes – but function in the same way as the normal ones.

                              Multi Pin Connectors - These are for the later SATA Hard Drives.

                     4 Pin Berg Connector – These are for supplying power to small form factors such as your floppy drive – they normally spur

                               of a Molex connector. (normally 1 red, 2 black and 1 yellow wire)

                               Some of the older AT power supplys have a separate power supply direct from the PSU to the On/Off Switch – these are

                                normally  1 white, 1 black, 1 blue and 1 brown wire.

                               Occasionally there are other ones that are unique to a particular function - normally additional hardware.

ATX Power Supply Pinouts
Below are pinout diagrams of the common connectors in ATX power supplies.

If this is the correct power supply that you are looking for but there are not enough Molex or floppy connectors please ask - I have splitters available, that plug directly on to the connector to give you either more Molex or floppy connectors. 

If you still can not find what power supply unit you need - please check my other power supply units that I have for sale.  I always have over 200 in stock.

Remember - many makes and models are exactly the same - just different **Manufacturers' numbers and stickers - as long as the following match:

1.    Max Output Power is the same or greater.

2.    The replacement has the right style of connectors to match your one.

3.    The replacement unit has the same or greater number of a particular connector (ie your requirements need 3 Molex connectors, but the replacement has 5 - that does not matter)

4.    The dimensions are the same.   

**Packard Bell, E Machines, I Machines mainly use FSP Group Power Supplies, most of Sparkle, Fortron, Powerman, AOpen power supply units are made by FSP (if you check their manufacturers' number they nearly all start with FSP)

Enlight / Chieftec / Jeantec all use the same manufacturer for their Power Supply Units (Their numbers nearly always start with HPC)

Courier costs are for mainland UK (Less Scottish Highlands) and mainland Western Europe - for outside these areas please contact me 

For Accurate Description Purposes – Second user Power Supply Units maybe a little dusty.
