850W 80+ Gold ATX Power Supply Unit
The RX 6800 XT requires high sustained amperage and exhibits significant transient power spikes that frequently exceed the OCP limits of older or lower-wattage power supplies, causing the motherboard to hang on the VGA initialization step. A high-quality 850W unit provides the necessary headroom for Navi 21 architecture. Ensuring separate, non-split 8-pin PCIe cables are used is critical for clearing the motherboard's white debug LED.
