Product Overview This SQC118 power adapter cable features a 12VHPWR 12-pin male connector (for GPU) on one end, and 2 8-pin (6+2) male PCIe connectors (for PSU) on the other. The 20cm braided cable uses 18AWG copper cores, with reinforced joints and a wear-resistant nylon jacket. It's designed to bridge older PSUs (with dual 8-pin outputs) to PCIe 5.0 GPUs, delivering stable power while fitting neatly in PC builds.

Safety & Usage Tips

For safe, reliable use of your SQC118 12VHPWR cable:

1.Check PSU Power

Make sure your PSU's dual 8-pin (6+2) ports can supply at least 600W total (this cable's max support). Insufficient power risks damaging your GPU/PSU.

2.Confirm Compatibility

Only works with:

.PSUs with 2 free 8-pin (6+2) PCIe ports
.GPUs with 12VHPWR 16-pin ports (e.g., RTX 40 Series).
Not for 6-pin/single 8-pin PSUs or non-12VHPWR GPUs.

3.Secure Connections

Push both ends until you hear a “click” — loose fits cause power cuts, overheating, or hardware failure.

4.Handle Carefully

.Avoid high heat (＞60°C) or humidity (prevents aging/short-circuits).
.Don't bend sharply at connectors (protects internal wires).

5.Warranty Note
This is a third-party cable. Some brands limit warranty for non-OEM parts — check your GPU/PSU's warranty terms first.
