PIYANYO 8-pin to 4-pin CPU Power Adapter

This adapter converts a single EPS12V 8-pin female connector into both an ATX12V 8-pin male and an ATX12V 4-pin male connector. It suits builders whose motherboard requires dual CPU power inputs but whose power supply provides only one 8-pin CPU cable. The 20 cm length keeps routing tidy inside compact cases.

UL1007 18AWG cable with 34-strand tinned copper

The 18AWG wire gauge and tinned copper strands are rated for continuous current delivery to the CPU voltage regulators. Under sustained load the cable resists heat build-up better than thinner alternatives, maintaining stable voltage to both 8-pin and 4-pin sockets simultaneously. The 20 cm run minimises voltage drop across the adapter.

Replaces a missing second CPU power cable

Use this when upgrading to a motherboard with 8+4 pin CPU power while retaining an existing power supply that lacks the extra connector. It is not a substitute for a native PCIe power cable and must not be used for graphics cards. The jump is worth it when the PSU has sufficient 12 V capacity but lacks the physical 4-pin CPU lead.

Questions about this item

Does the 18AWG tinned copper wire run hot when the CPU draws full power all day?

The 18AWG UL1007 tinned copper conductors are rated for the current a CPU 8-pin socket delivers, so they stay cool under normal sustained loads.

What power-supply connectors must my PSU already have for this adapter to work?

Your PSU needs one free EPS12V 8-pin CPU cable; the adapter splits that single connector into an 8-pin male and a 4-pin male for the motherboard.

Will this work on an older board that only has a 4-pin CPU socket?

Yes — the 4-pin male connector (Connector C) plugs directly into a legacy ATX12V 4-pin socket while the 8-pin male can stay unused.
