Power supply for PC: wattage and efficiency

The power supply feeds your whole computer, so do not skimp. Add up your graphics card and CPU consumption and pick a PSU with some headroom: 650W for mid-range builds, 750W and 850W for high-end builds, and 1000W for extreme setups.

The 80 Plus Bronze or 80 Plus Gold label tells you about efficiency, and a fully modular PSU makes cabling easier. These are ATX power supplies for PC cases, not DC or 12V adapters, and not an uninterruptible power supply (UPS).

How to choose your PC power supply?

The power supply is the component that protects your entire investment. A poor-quality PC PSU can damage your GPU, CPU or RAM. These are the key factors:

Every power supply in our catalog ships directly from Amazon, with official warranty and hassle-free returns.

Frequently Asked Questions

How many watts do I need?
RTX 5060 / RX 9060 XT: 650 W. RTX 5070 / RX 9070 XT: 850 W. Always add 150 W headroom above total system power draw.
What does 80+ Gold mean?
Minimum 87–90% efficiency under typical load. Less heat, less fan noise, and measurable electricity savings vs. uncertified units.
Modular vs non-modular?
Modular: only cable what you need — better airflow and cable management. Non-modular: cheaper but all cables are permanently attached.
Is ATX 3.1 required for new GPUs?
Yes for RTX 5000 and RX 9000. It includes the native 12V-2×6 connector, replacing the risky 8-pin adapter with a safer, higher-power connection.
Does PSU brand matter?
Critically. A cheap uncertified unit can destroy all connected components. Prioritize brands with Japanese capacitors and 5–10-year warranties.
