  • Rated for systems up to 2000 W to stop GPU throttling

Dual PSU adapter for high-draw systems

The myVolts ADD3PSU connects two power supplies to one motherboard using a 24-pin main connector and two 24-pin secondary connectors. It supports 20+4 pin configurations for 24-pin or 20-pin use. Builders running power-hungry graphics cards can add capacity without replacing existing units. The 85 cm cable length suits full-tower layouts.

Sustained load behaviour

The adapter links supplies so they share the system load continuously rather than in brief spikes. It is rated for combined units up to 2000 W, letting multi-GPU or overclocked configurations draw steady current without triggering protection circuits. The thin-wire design maintains stable transmission across the 85 cm run. No active components are present to introduce latency or failure points.

Thermals noise and power draw

The passive ABS and metal construction adds no fan noise or heat of its own. Power draw is limited to the negligible loss across the connectors and 85 cm of wire. Operating temperature follows the power supplies themselves, with no additional thermal load on the motherboard. The compact form factor keeps airflow paths clear in crowded cases.

Questions about this item

Does the 85 cm cable add noticeable heat or power loss when the system runs all day?

The adapter uses a thin-line design for stable transmission and does not generate heat itself; total draw stays within the 2000 W rating of the connected supplies.

What must I already own to use the 24-pin 20+4 main and dual 24-pin secondary connectors?

You need one primary ATX power supply and one or two additional ATX units, each with a standard 24-pin output, plus a motherboard that accepts a 20+4 pin main power plug.

Will the adapter work with an older 20-pin motherboard and legacy power supplies?

Yes, the 20+4 pin main connector separates to fit 20-pin boards, and the secondary 24-pin plugs accept standard ATX outputs from older units.
