Dual PSU adapter for high-power builds

The myVolts Dual PSU Adapter lets you connect two power units to a single motherboard through one main 24-pin female 20+4 connector and two secondary 24-pin female connectors. It supports a combined capacity within 2000 W and works with both 24-pin and 20-pin motherboard sockets. The 85 cm cable length gives flexibility for routing inside large chassis. This adapter targets builders who need extra wattage for demanding graphics cards without replacing existing power supplies.

Passive design with no added heat or noise

The adapter contains no active components, so it adds no fan noise and generates no measurable heat of its own during normal operation. Power draw is limited to the negligible loss across the connectors and the thin-cable conductors. Because it simply splits and combines the ATX power lines, system thermals and acoustic profile remain identical to running a single power supply. The ABS and metal construction keeps the assembly compact and portable for service work.

Sustained load stability depends on the supplies

Under continuous heavy load the adapter passes whatever current the two connected units deliver, so stability is determined entirely by the quality and rating of those power supplies. The thin-line design keeps voltage drop low over the 85 cm run, but the adapter itself has no protection circuits or monitoring. Builders who need redundant or hot-swap power, or who require certified current-sharing between dissimilar units, cannot rely on this passive cable alone.

Questions about this item

How do I install the adapter and which connector mistake should I avoid?

Plug the 20+4 pin end into the motherboard, then connect each PSU to one of the two 24 pin female sockets; the common error is leaving the 4 pin section unattached when the board needs a full 24 pin connection

What maintenance or replacement will this adapter need later?

No scheduled maintenance is required; replace the cable only if the ABS housing cracks, pins bend, or the thin wires show insulation damage after repeated handling

What limit appears first under sustained use with this adapter?

The combined draw of the connected PSUs must stay within the 2000 W application ceiling; exceeding that rating will trip protection or overheat the thin cable before any other limit is reached
