JSER EP-107 PCI-E Riser Adapter

The JSER EP-107 is a PCI-E 1x to 16x extender riser designed to connect graphics cards to a single-lane slot. It includes a 60 cm USB 3.0 cable, a SATA 15-pin to 6-pin power cable, and four FP solid capacitors for stable power delivery. The board measures 10 cm by 10 cm by 1 cm and weighs 0.05 kg. A locking 16x slot secures the installed card.

Suits multi-GPU builds needing slot separation

This adapter suits builders running multiple graphics cards who want to reduce the load on the motherboard power plane. The independent SATA power feed and solid capacitors help keep voltage steady across several cards. It is not for systems that lack a free SATA power connector or a physical 1x slot. Buyers needing an internal cabled connection without external power should look elsewhere.

Check slot clearance and power headers before

Verify the motherboard has an open PCI-E 1x slot with enough surrounding space for the 10 cm board and the 60 cm USB cable bend radius. Confirm the power supply provides a spare SATA 15-pin connector for the included 6-pin adapter. Ensure the chassis can accommodate the card once it is mounted on the riser. No driver installation is required for the adapter itself.

Questions about this item

Do I need a free PCIe 1x slot on my motherboard to install the EP-107 riser?

Yes, the riser board plugs into a PCIe 1x slot, while the 16x adapter holds the graphics card and locks it in place.

Will the 60 cm USB 3.0 cable reach a GPU mounted outside a standard mining frame?

The 60 cm cable gives enough length to position the card away from the motherboard in most open-air frames.

How can I verify the four FP solid capacitors are delivering stable power after setup?

The system should POST normally and the GPU should appear in device manager without power-throttling warnings.
