A power-supply guide covering wattage headroom, ATX 3.x, 12VHPWR/12V-2x6 cables, efficiency, and cable safety.
Headroom is practical
Modern GPUs can have short transient spikes. A good PSU choice leaves headroom, uses the right native connectors when possible, and avoids cable adapters when a cleaner certified option is available.
Cable warning
Never mix modular PSU cables between brands or even different models unless the manufacturer explicitly says they are compatible.
