Vszerda Dual PSU 24-Pin Extension Cable 12in 18AWG

SKU CH-976A-62KC7

Connects a second ATX power supply to a 24-pin or 20+4-pin motherboard using 18AWG cables with 12-inch main and secondary lengths

  • Connect a second PSU with a single 24-pin adapter cable
  • Supports both 24-pin and 20-pin ATX motherboards via 20+4 male connector
  • Twin 12-inch 18AWG leads keep secondary PSU placement flexible
  • Powers main and secondary supplies simultaneously for mining or gaming rigs
  • Brand-new condition ensures reliable dual-PSU operation

Dual PSU adapter for ATX boards

This 24-pin extension cable lets a single motherboard draw power from two separate power supplies at once. It fits both 24-pin and 20+4-pin ATX connectors, making it suitable for mining rigs or multi-GPU workstations that need more current than one unit can provide. Builders who only have a single PSU will not need this adapter.

Sustained load behaviour

The 18 AWG conductors carry the combined current from both supplies through a 12-inch main lead and a 12-inch secondary lead, totalling 30 cm each. Because both PSUs are switched on simultaneously, the motherboard receives stable power without the voltage droop that can occur when a single unit hits its limit. Systems that never exceed one PSU’s rating will see no difference.

Thermals noise and power draw

The cable itself adds no active cooling or noise; it simply passes whatever power the connected supplies deliver. Wire gauge and length are chosen to keep resistive losses low during continuous high-current operation. Users must ensure each PSU is adequately cooled, as the adapter does not change the thermal load of either unit.

Questions about this item

Does the 18AWG wire handle continuous mining loads without overheating?

The 18AWG cable is rated for standard ATX currents and the 12-inch length keeps voltage drop minimal during sustained high-draw mining sessions.

My motherboard only has a 20-pin ATX socket; will the 20+4 male connector fit?

The 20+4 male plug splits so the 20-pin portion seats directly in your board while the extra 4 pins hang clear.

Can I keep my existing 24-pin PSU cables and just add this adapter for a second unit?

Yes, the kit provides two 24-pin female ports so your original PSU stays connected while the secondary PSU plugs into the other port.
