myVolts Dual PSU 24-pin Starting Cable 30cm

SKU CH-EZ43-XG6FN

A 30 cm dual-PSU adapter that lets two power supplies up to 1300 W each start together via a single 24-pin motherboard connector, using UL1007 cable rated for 2000 W total

  • TypeAT
  • Connect two PSUs to one motherboard with a single 24-pin cable
  • 30 cm length keeps dual-PSU mining builds tidy inside the case
  • UL1007 wiring rated for 500 W to 1300 W power supplies
  • Separate 24-pin outputs prevent mixing power rails between units
  • Supports combined loads up to 2000 W for high-demand components

Dual PSU cable for ATX motherboards

This 24-pin adapter connects two power supply units to a single motherboard, allowing them to start and shut down together. It is aimed at mining rigs or high-power builds that need more current than one PSU can deliver. The 30 cm length keeps the link short inside the chassis. Only the primary PSU should feed the motherboard; the secondary PSU powers drives and peripherals separately.

Thermals noise and power handling

The cable uses UL1007 standard wire rated for high current and is described as suitable for 500W to 1300W power supplies with a connector rating below 2000W. No active cooling or fan is present, so the assembly adds no audible noise. Heat dissipation depends entirely on the wire gauge and the load drawn through the two PSU connections. Proper seating of both 24-pin plugs is essential to avoid resistance and localised warming.

Build integration and cable management

One male 24-pin plug attaches to the motherboard while two female 24-pin sockets accept the PSU cables, replacing a single PSU-to-board link. The short 30 cm run helps reduce clutter and supports cleaner routing for modding enthusiasts. Mixing outputs from the two supplies on the same rail is explicitly discouraged, so the builder must keep motherboard power on one unit and drive power on the other.

Highlights

  • Connect two PSUs to one motherboard with a single 24-pin cable
  • 30 cm length keeps dual-PSU mining builds tidy inside the case
  • UL1007 wiring rated for 500 W to 1300 W power supplies
  • Separate 24-pin outputs prevent mixing power rails between units
  • Supports combined loads up to 2000 W for high-demand components

Questions about this item

How do I install the 24-pin dual PSU starting cable so the motherboard only draws from the primary PSU?

Plug the single 24-pin male end into the motherboard, then connect each 24-pin female end to its own PSU. Use the primary PSU's 24-pin outputs for the motherboard and the secondary PSU only for drives or peripherals — never mix the two supplies' outputs.

What maintenance will the UL1007 cable need over time?

The UL1007 standard wire is rated for long service life; inspect the 30 cm cable periodically for kinks, cracked insulation or loose pins, and replace it if any conductor is exposed or a connector feels loose.

At what power level does the 2000 W connector rating become the limiting factor?

The cable's connector is rated below 2000 W, so sustained loads approaching that level will hit the connector limit before the 1300 W PSU headroom does.
