The Riser PCI-E 1x-16x guarantees more stable operation of mining systems. It is made from a PCI-E 16x socket (female), a USB cable, a PCI-E 1x socket (male), a PCI-E/SATA plug, and a 6 PIN plug, which allows you to connect additional power to the card. You can reduce the load on the motherboard and avoid bloated components while multiple graphics cards operate simultaneously. It is the cheapest way to improve ventilation while allowing the use of all available PCI-E 1x slots.
