Ruth's sister TF400 ATX 400W RGB 80 PLUS internal power cable

SKU CH-C12G-2DX46

A 400 W ATX power supply with RGB lighting, 80 PLUS efficiency, and a 20+4 pin mainboard connector for desktop and server builds

  • 80 PLUS certification reduces energy waste
  • 400 W output powers mid-range gaming builds
  • Active PFC stabilises input from 164 to 220 V
  • RGB fan adds customisable lighting
  • Non-modular design keeps cabling simple

Product identity

The Ruth's sister TF400 is a non-modular ATX power supply rated at 400W with 80 PLUS certification. It targets desktop and server builders who need a basic unit with integrated RGB lighting and a fixed cable set.

Installation notes

The unit fits a standard ATX bay and uses a single 12 cm fan for cooling. Because cables are fixed, routing the unused 20+4 pin, 4+4 pin CPU, 6+2 pin graphics, four SATA and two IDE connectors can be tight in compact cases; plan cable paths before securing the PSU.

Compatibility check

Verify that your motherboard accepts a 20+4 pin main power connector and an 8 pin CPU connector. Confirm the graphics card requires no more than a single 6+2 pin feed and that the 164-220V input range matches your local mains supply.

Questions about this item

How do I confirm the 80 PLUS certified 400W unit is running correctly after installation?

The system should power on with stable voltages on the 20+4 pin mainboard and 4+4 pin CPU connectors, and the single fan should spin without abnormal noise.

What cables come in the package and which ones must I source separately?

The box includes 20+4 pin mainboard, 4+4 pin CPU, 6+2 pin graphics, four SATA and two IDE connectors; any additional SATA or PCIe cables would need separate purchase.

Which version of the TF400 ATX 400W RGB should I choose for a desktop build needing two 6-pin GPU connectors?

This model provides exactly two 6-pin graphics connectors, four SATA ports and two IDE ports, matching the listed specification for desktop or server use.
