2 Pack SATA Male to 8 Pin (6+2 Pin) PCI-E Female Power Adapter Cable 20CM

Two-pack SATA-to-PCIe power adapter

This two-pack converts a 15-pin SATA male connector into an 8-pin (6+2) PCI-Express female connector for graphics cards. Each cable measures 20 cm and uses PVC insulation with pure copper conductors. The split 8-pin end detaches to serve as a 6-pin plug when needed. It suits builders adding a GPU to a system whose power supply lacks native PCIe leads.

Sustained-load behaviour

The adapter passes whatever current the SATA source provides, but the SATA plug is rated at 12 V × 4.5 A for a maximum of 54 W. An 8-pin PCIe socket can demand more power than that limit, so continuous heavy GPU loads risk overheating the SATA connection or melting the connector. The cable itself does not regulate current; it simply bridges the two interfaces.

Build and daily use

Black-and-yellow PVC sheathing protects the copper wires, and the detachable 6+2 pin head locks into the graphics card with a standard latch. Firm seating on both ends prevents intermittent contact that can cause instability. The short 20 cm length keeps cable routing tidy inside compact cases, but it also means the SATA power port must sit close to the GPU. Users needing longer reach or higher safe wattage should choose a power supply with native PCIe cables instead.
