SXDOOL ATX CPU 8 Pin (4+4) Male to Female Extension Cable 30cm (2-Pack)

Extension cable for ATX CPU power

This two-pack provides 30 cm male-to-female extensions for the standard 8-pin (4+4) CPU power connector. The cables use UL 1007 rated 18AWG tinned copper wire for reliable conductivity. They suit builders who need extra reach when routing power from the PSU to the motherboard socket. The 9.5-inch length helps tidy cable runs in larger cases or behind motherboard trays.

Sustained current delivery

The 18AWG conductors are rated for continuous operation at typical CPU power loads without significant voltage drop across the 30 cm span. Tinned copper resists oxidation that could increase resistance over time. The connectors maintain a secure fit through repeated thermal cycles in a running system. Builders who need longer runs or higher current capacity than 18AWG supports should consider a different gauge.

Thermals and power draw

The cable assembly adds negligible resistance so it does not measurably increase system power draw or generate noticeable heat under normal loads. No active cooling is required and the wire insulation remains within its temperature rating during sustained use. The flexible UL 1007 jacket allows clean routing without stress on the motherboard or PSU connectors. Users requiring in-line temperature monitoring will not find that feature here.
