Cable Extension Kit for Custom Builds

The Monoprice 187 kit adds sleeved 18AWG extensions to an existing modular power supply. It includes a 24-pin motherboard cable, two 8-pin CPU cables and two 8-pin GPU cables, all in a blue-black braid. The 500mm length and included combs suit full-tower cases where stock cables fall short. Builders seeking a coordinated look without rewiring the PSU will find the set complete.

Replacing Short or Mismatched Stock Cables

Stock modular cables are often too short for clean routing behind large motherboards or around thick radiators. These extensions bridge the gap without replacing the PSU loom, so the original warranty stays intact. The jump is worth it when cable combs cannot align factory leads or when a colour theme demands uniform sleeving across every visible wire.

Check Connector Compatibility and Clearance

Verify that your PSU uses standard female modular ports so the female-to-female extensions seat correctly. Confirm the 24-pin, 4+4 CPU and 6+2 GPU pinouts match your components, as some proprietary units differ. Ensure the 500mm reach fits your routing path and that the stiff braid can bend within your case’s cable channels without stressing sockets.

Questions about this item

What clearance does the 500mm cable length need inside a case?

The 500mm extensions add half a metre to each power run, so allow extra depth behind the motherboard tray and beside the GPU for the 24‑pin, two 8‑pin CPU and two 8‑pin GPU connectors.

How are the included cable combs installed on the braided sleeves?

Slide each comb over the 18AWG wires before routing, then snap it shut to lock the cables in a straight line; the combs grip the high‑density cotton sleeve without tools.

When should the 18AWG tinned‑copper extensions be replaced?

Inspect the UL 1015 insulation and braided sleeve annually; replace any cable showing cracked sheathing, melted pins or frayed braid to maintain safe power delivery.
