Choosing a power supply
The power supply feeds every other part. Size it for your graphics card with headroom, and do not save money here.
Wattage
Add up the CPU and GPU power and leave 30 to 40% headroom. Most single-GPU gaming PCs fall between 650 W and 850 W.
Efficiency
80 Plus Gold units waste less power as heat and usually run quieter than Bronze.
Modern GPUs
ATX 3.0 / 3.1 power supplies with a native 12V-2x6 cable connect directly to recent NVIDIA cards without adapters.
Common questions about power supplies
Is a bigger PSU wasteful?
No. A PSU only draws what the system uses. Sizing above peak load keeps it efficient, cool and quiet.
Will a good PSU protect my PC from power cuts?
A quality PSU handles small dips, but not outages or generator switchovers. Pair the PC with a UPS for that.
