PCIE 5.0 Riser Cable




Is it backward compatible with Gen4 or Gen3 motherboards?
Yes. Slots negotiate the highest common rate; a buyer paired RTX 3080/3090 over this cable on a Gen4 x4 slot.
Is the power delivery enough for an RTX 5090?
Yes - the 40-pin connector dedicates 10 pins to 12V for up to 78W, sized for RTX 5090-class flagship cards.
Which length should I choose for my case?
Measure slot-to-GPU distance first. Short sizes suit vertical mounts; 400mm to 1m cover full towers, benches and servers.
How should I route and secure the cable?
Seat both ends fully and route gently - never pull hard or fold sharp. Support the card; rough handling can damage the PCB.
Does it need drivers, power or a specific OS?
No drivers and no OS limits. The 78W feed comes through the slot-side connector, so no external power is needed.
