Prioritise units from reputable brands with 80+ efficiency ratings (Bronze, Gold, Platinum). Check that the wattage meets your system requirements with some headroom. Modular PSUs are easier to work with for cable management. Ask the seller about the unit's age and whether it has exhibited any coil whine or fan noise.
A typical gaming PC with a mid-range GPU needs 550-650W. High-end builds with RTX 4080/4090 cards may need 850W or more. Use an online PSU calculator with your specific components for an accurate recommendation, and add 100-150W of headroom for reliability.
