Extension kit for PSU cables

This Monoprice RM kit adds 30 centimetre sleeved extensions for a 24-pin ATX motherboard connector, one 4+4-pin EPS CPU connector and two 6+2-pin PCIe GPU connectors. The 18AWG UL1015 wires are rated for power supplies up to 800 watts. Four combs per cable keep the braids aligned inside the case.

Build integration and clearance

Male-to-male terminals plug directly onto existing modular PSU leads, so the original cables stay in place and no rewiring is required. The soft nylon braid bends easily around tight routing channels and behind motherboard trays. Each extension ships with three standard combs plus two alternate styles to match different aesthetic preferences.

Thermals noise and power draw

Passive cables add no fan noise and generate no measurable heat under normal loads up to the 800 watt rating. The 18AWG gauge keeps voltage drop negligible across the 30 centimetre length. Compatibility spans RTX 20, 30 and 40 series plus RX 5000, 6000 and 7000 series graphics cards without adapter changes.

Questions about this item

Will the 18AWG wires handle an 850W PSU under continuous load?

The kit uses UL1015 18AWG wire rated for power supplies up to 800W, so an 850W unit exceeds the specified limit.

Do the nylon-braided cables and combs stay cool and quiet during all-day operation?

The extensions are passive cables with no moving parts; they add no noise and the soft braided sleeve does not generate measurable heat under normal use.

Which existing PSU connectors are required for the 24-pin ATX, 4+4-pin EPS and dual 6+2-pin PCIe plugs to work?

You need a modular PSU that already provides a native 24-pin ATX, an 8-pin EPS and two 8-pin PCIe outputs to plug these extensions into.
