Flexible PCI-Express Riser Cards

BTX Desktop PSU


-These PCI-Express extenders are essential for standard computer building as well as for intensive gaming and Litecoin, Bitcoin, Dogecoin mining rigs.

-These High Quality Powered Riser cards are powered via a double wired Molex connector. This helps reduce the power usage from the motherboard preventing GPU and Motherboard damage when using multiple high spec GPUs.

-The smoothing solid capacitor also increases GPU stability by regulating the voltage.

-The gold plated contacts provide a better conductivity and a longer product life.


A PCI-Express riser card is only a serial point-to-point connection between the motherboard and the card. Compared to a small x1 riser card, a larger x16 riser card has additional communication lanes in parallel allowing higher speed. 

Conveniently, any size of PCI-Express card (x1, x4, x8, x16) can be plugged in any kind of PCI Express motherboard slot.

A small card x1 can be plugged in a x1, x4, x8 and x16 motherboard slot. Obviously, the bandwidth available will only be x1.

A large x16 card can also be plugged in a smaller slot (x8, x4, or x1) providing the slot has an open end to allow the card to be pushed all the way down. Again, the bandwidth available will be limited by the number of lanes of the slot.

Note that sometimes a PCI-E slot operates with fewer data lanes than it is supposed to. For example, a x16 slot may have a data connection of only x8, in which case a x16 card plugged in will only have an x8 bandwidth available. Have a look inside the slot to see how many contacts it actually has.

PCI-E 1x to 16x HQ Powered Ribbon Riser Card:


This powered flexible riser card allows the connection of a PCI-E 16x card to any PCI-E slot on the motherboard (1x, 4x, 8x or 16x).

Total length: 20cm (8inches).


PCI-E 16x to 16x HQ Powered Ribbon Riser Card:


This powered flexible riser card allows the connection of a PCI-E 16x card to a PCI-E 16x slot on the motherboard.

Total length: 20cm (8inch).Please tell us in the remark box if you prefere the longer 24cm (9.5inch) version.


PCI-E 1x to 16x Powered USB Riser Card. With Molex connector & Solid Capacitor:


USB cable length: 33cm (13inches)

USB3 allows fast data transfer.

This must-have item is ideal:

-to make use of any type of PCI-E motherboard slots (The small 1x connector can be plugged into any PCI-E slot (1x, 4x, 8x or 16x).

-when the card is placed far away from the motherboard,

-to increase air flow (The USB cable does not obstruct the air flow as much as a ribbon riser card).
