ATX Power Supply Unit (650W 80+ Gold)
The RTX 3060 has high transient power spikes that often trigger the Over-Current Protection (OCP) on older or lower-wattage power supplies during the POST phase. Upgrading to a modern 650W unit ensures the +12V rail can handle the initial initialization load of the Ampere architecture. This resolves the 'No Post' by providing a stable voltage reference during the motherboard's VGA check.

PCIe 8-Pin Power Cable
Intermittent or failed POSTs are frequently caused by poor pin-to-socket contact or a degraded 8-pin PCIe lead that cannot deliver the required amperage. Replacing the individual cable (on modular units) or ensuring a dedicated non-daisy-chained lead is used ensures the card receives full power to release the BIOS hold. This is the most granular sellable component before replacing a full assembly.

Nvidia RTX 3060 Graphics Card
If power delivery is verified and the motherboard BIOS is updated but the system still fails to POST, the vBIOS on the GPU itself or a MOSFET on the card's VRM (Voltage Regulator Module) has likely shorted. As board-level micro-soldering is not a standard field-serviceable task, the entire GPU assembly must be replaced.
