Dual 4 Pin Molex to ATX 8 Pin Video Card GPU Power Supply Cable 8.6'' 22cm

Bottom line: The Dual 4 Pin Molex to ATX 8 Pin Video Card GPU Power Supply Cable 8.6'' ($5.59 on Amazon as of 2026-10-06): Adds an 8-pin PCIe feed to PSUs that only have 4-pin Molex outputs; main trade-off: short 8.6in (22cm) reach limits routing in larger cases.
