Biostar X870E Valkyrie

The X870E Valkyrie is Biostar's flagship return to the high-end motherboard market, bringing a 22-phase VRM, PCIe 5.0 support, and USB4 Type-C to the X870E chipset from a brand better known for budget boards, aimed at buyers curious about an alternative to the big four manufacturers.

Power delivery uses a 22-phase design with 110A Dr.MOS stages, putting it in the same VRM tier as many ASUS and MSI X870E flagships on paper, though Biostar's board has less independent long-term testing than more established competitors. Four DDR5 DIMM slots support up to 48GB per module with dual-channel operation, offering roughly 50% more bandwidth than equivalent DDR4 configurations. The board supports PCIe 5.0 for both GPU and M.2 storage, though Biostar's public specification pages provide less detail on exact slot counts and configurations than competing brands. USB4 Type-C is included with 40Gbps transfer speeds, an unusual inclusion at this price tier. Biostar's specification pages do not detail the exact LAN speed or Wi-Fi standard for review purposes. Against the ASUS ROG Crosshair X870E Hero in this catalog, the Biostar X870E Valkyrie targets a similar 22-phase VRM tier at what is typically a lower price, but comes from a brand with a much smaller motherboard market share and less community BIOS support history.
