KHACHIMO RD540 RD640 ATX Power Supply

The KHACHIMO RD540 RD640 is an ATX form factor power supply built to the DPS-550AB-2 A specification. It arrives in new condition and has been tested working to confirm reliable operation. This unit is intended for desktop systems requiring a standard ATX power source.

Suitable for standard ATX desktop builds

This supply suits builders assembling or repairing a desktop that uses an ATX power supply and who value a unit verified as working. It is not for systems needing a different form factor such as SFX or TFX, nor for configurations that demand a higher rated output than the 550 W this model provides.

Questions about this item

How loud and hot does the RD540 RD640 DPS-550AB-2 A get when running continuously all day?

The unit has been test-worked and is described as good quality, but no noise level, temperature or power-efficiency figures are provided for sustained operation.

What existing parts or cables must I already have to install this ATX power supply in my system?

It follows the ATX form factor, so a compatible case and motherboard with standard ATX mounting points and power sockets are required.
