i need a low power server 8 sata port motherboard ecc memory 1 pci slot

If you’re aiming to build a low-power NAS using the Jonsbo N3 case with 64GB ECC memory support, an 8-SATA-port motherboard, and a single PCIe slot, here are a few things to prioritise given your $350 budget:

You’ll most likely need to go with an AMD platform if ECC support is essential and you’re keeping to budget. Some AMD consumer boards unofficially support ECC when paired with Ryzen Pro or certain regular Ryzen CPUs, though it depends on board firmware. If you’d prefer guaranteed ECC support, then a workstation-grade board or used server platform might be the better route.

Currently, there are three main options worth exploring:
1. ASRock Rack B550D4U or X570D4U – These are workstation/server-grade micro-ATX boards with full ECC support, IPMI remote management, and often 8 native SATA ports. They’re reliable and designed for NAS/home server builds. The X570D4U may exceed your budget slightly, but the B550D4U occasionally dips into your price range second-hand.
2. Supermicro X11SCL-F or X12STL-F (used) – LGA1151 or LGA1200 server boards with 6–8 SATA ports, full ECC support, and IPMI. Paired with a Xeon E-2200 or E-2300 CPU, these are very efficient and stable. These setups are common in low-power NAS builds and can often be found in the used market under $350 total.
3. Consumer AM4 board + SATA expansion card – If you can’t find an 8-port board within budget, consider a reliable 6-port AM4 motherboard with ECC-tolerant BIOS (e.g., ASRock B550M Pro4) and add a SATA HBA (like an LSI 9211-8i or 9207-8i flashed to IT mode). This adds flexibility and can keep the overall cost lower, especially if you already have a Ryzen CPU with ECC support.
