Interface Card Qoltec 55501

The Qoltec 55501 interface card is a PCI-E riser cable assembly designed to improve stability and connectivity for mining rigs and systems using multiple graphics cards. It includes a PCI-E 16x (female) socket, a USB cable, a PCI-E 1x (male) connector, a PCI-E/SATA power plug and a 6-pin power plug to provide additional power to the graphics card and reduce stress on the motherboard when several GPUs operate simultaneously.

Advantages

This PCI-E 1x–16x riser offers a cost-effective way to distribute power and reduce motherboard trace overloads, helping prevent blown circuits during heavy multi-GPU use. The design enables better airflow and positioning of graphics cards, while the included power connectors (SATA/6-pin) provide stable auxiliary power to the GPU.

Suitable for (tasks / use cases)

• GPU mining rigs with multiple graphics cards
• Systems where improved GPU ventilation and spacing are required
• Motherboards with limited full-size PCI-E slots but available PCI-E 1x sockets

Key specifications

• Type: PCI-E 1x to PCI-E 16x riser cable
• Connectors: PCI-E 16x (female), PCI-E 1x (male), USB cable
• Power options: PCI-E/SATA power plug and 6-pin power plug
• Purpose: Offloads power draw from motherboard and enables remote GPU placement

How to use

Install the PCI-E 1x (male) connector into an available PCI-E 1x slot on the motherboard, attach the PCI-E 16x (female) socket to the graphics card, and connect the USB cable between the riser board and the adapter. Plug the SATA or 6-pin power connector into an appropriate power supply line to provide supplemental power to the GPU. Ensure all connectors are firmly seated and the system is powered off while installing.

Usage recommendations

Use the Qoltec 55501 riser in well-ventilated rigs and verify power supply capacity before adding multiple GPUs. Avoid forcing connectors and periodically check cables and power plugs for secure connection and signs of wear.
