JGINYUE B650 add-in card trades port count for unmeasured power
JGINYUE's B650 add-in card costs 388 yuan, or US$58, and puts four M.2 slots, a 10 Gbps USB-C port, and a 2.5 G LAN into one PCIe slot.

JGINYUE's B650 add-in card is priced at 388 yuan, or US$58, for the 10 Gbps Type-C version. The card puts four M.2 slots, two USB 3.0 Type-A ports, one 2.5 G LAN port, and a 10 Gbps USB-C port into a PCIe expansion slot. The Wccftech page says "blazing fast connectivity", but the X filing is the document I trust, and the number that decides it is 10 Gbps.

Port count is not the limit. The buyer is constrained by power and cooling. JGINYUE recommends the 6-pin PCIe connector even for SSD-only use, which means the card is not a passive slot add-on. The 4-pin fan header has no speed control, and the 40 mm fan is not included, so thermal behavior is left to the builder. That changes the buyer's cost: the $58 price excludes the fan and any measured proof that four NVMe drives can stay within the card's power budget.

What remains unmeasured is the actual PCIe lane allocation, SSD sequential throughput, sustained USB transfer, power draw, and fan noise. The 20 Gbps version is announced, but its price, timing, and port behavior are not in the document yet. The filing proves the port list and the 10 Gbps label; it does not prove that four drives can run at full speed without the auxiliary connector at all.

The 6-pin PCIe connector is auxiliary USB power, and JGINYUE recommends it even for SSD-only use. The 4-pin header lacks speed control, so thermal and power behavior are not validated by the filing.
