PCIe Slot Specifications Overview
The HP EliteDesk 800 G3 SFF features a well-designed motherboard with multiple PCIe slots. Primarily, it includes one PCIe x16 slot for high-bandwidth cards like GPUs, one PCIe x4 slot for expansion cards, and additional x1 slots for peripherals. All slots are PCIe 3.0 compliant, delivering up to 8 GT/s per lane for optimal data transfer rates.
- PCIe 3.0 x16: Full-length, ideal for discrete graphics
- PCIe 3.0 x4: Mid-sized for RAID controllers or sound cards
- PCIe 3.0 x1: Low-profile for Wi-Fi or USB expansion
Compatibility and Limitations
While versatile, the SFF chassis imposes size restrictions—only low-profile or half-height cards fit. Power supply is 250W, so high-end GPUs may require PSU upgrades. Check BIOS settings for slot bifurcation options to split x16 into x8/x8 for multi-GPU setups.
Common compatible cards include NVIDIA Quadro series, AMD Radeon low-profile models, and NVMe adapters. Always verify physical dimensions and power connectors before purchase.
- Max card length: 208mm
