Target City/Region: Toronto, Canada
Toronto PC builders know the frustration: you buy a sleek custom cable, plug it into your PSU, and the system won‘t boot—or worse, sparks fly. The culprit is often pinout incompatibility.
Power supplies from different brands (Corsair, Seasonic, EVGA, be quiet!) use different pin assignments on the PSU side, even when the GPU side is standardized. A cable designed for a Corsair Type 4 PSU may deliver 12V to a ground pin if plugged into a Seasonic unit. Always verify compatibility charts from the cable manufacturer or the PSU brand itself.
For those building with high-end GPUs like the RTX 5090, the 12V-2x6 connector requires cables specifically rated for 600W. Look for 16 AWG wire gauge and connectors with visible sense pins. When in doubt, use the cables that came with your PSU—they‘re guaranteed to match. A few extra minutes of research saves hundreds of dollars in components.
