  • Reduces strain on motherboard and drive connectors

Power Adaptation for Legacy PSUs

This two-pack converts dual SATA 15-pin connectors into a single PCIe 8-pin (6+2) female plug, letting older power supplies feed modern graphics cards without dedicated PCIe leads. It targets builders upgrading GPUs on systems that only offer SATA power outputs. The 20 cm length keeps routing tidy inside compact cases.

Sustained Load Behaviour

Each cable uses UL 1007 18 AWG tinned copper rated for 300 V and 176 degrees Fahrenheit, with UL VW-1 flame testing for continuous operation. The dual-SATA design draws from separate rails, spreading current to reduce voltage drop during extended gaming or compute sessions. Correct polarity alignment is essential to avoid component damage under load.

Build Quality and Daily Use

Male-to-male terminals and a lightweight jacket simplify installation in tight drive bays or behind motherboards. The 19 cm span reaches from standard SATA headers to GPU sockets without excess slack. Users must verify PSU wattage headroom and distinguish the 8-pin PCIe plug from similar CPU 4+4 connectors to prevent misconnection.

Questions about this item

Does the 20 cm cable run hot when it powers a graphics card all day?

The 18 AWG tinned copper conductors are rated for 176 °F and 300 V, so normal GPU loads stay well within the cable’s thermal limits.

What power supply connectors must I already have free to use this adapter?

You need two unused 15-pin SATA power plugs from the PSU to feed the single 8-pin PCIe connector on the card.

Will the 19 cm length reach an older motherboard’s CPU 4+4 pin header if I try to repurpose it?

No — the pin-out on the 8-pin PCIe female end differs from the EPS 4+4 pin CPU header, so it cannot be used for that purpose.
