Open Box · Never Installed ASRock H510 Pro BTC+ Mining Motherboard LGA1200 · Intel 10th/11th Gen · 6 GPUs direct-mounted, no risers needed What it is
A purpose-built multi-GPU board from ASRock. Six full-length, steel-reinforced PCIe slots are spaced far enough apart to mount graphics cards directly on the board, so you skip the riser cables that cause most rig instability.
This unit is open box and has never been installed or powered on. It is in its original retail box.
Please read the slot details below before buying. All six slots are physically x16, but only Slot 1 runs at full x16. Slots 2 to 6 run at x1. That is how ASRock designed the board, and it is normal for mining boards.

Needs an open-air rig frame, not an ATX case Built for GPU racks
Each PCIe slot has its own independent power rail, and two extra 24-pin connectors let you split the load across multiple power supplies. During boot, the POST screen shows which slots detected a card, so a dead GPU or loose connection is easy to find.
Where it earns its keep
GPU mining and compute rigs. Up to 7 cards (6 direct-mounted plus 1 on the mining port) on one low-power platform.
GPU test bench. Plug in several cards at once and see at a glance which ones the board detects. Handy for anyone buying or reselling used GPUs.
Multi-GPU local AI. Works for running a large model split across several cards, where the x1 slots mainly slow down model loading. It is not a good fit for workloads that need full bandwidth to every card.
