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:
Wattage: calculate your build’s total draw and add a 20–30% margin; a good PC power supply never runs at its limit.
80+ certification: Gold or better on your PC PSU guarantees higher energy efficiency and less heat.
Modular or semi-modular: a modular power supply simplifies cabling and improves airflow inside the case.
Protections: the PSU must include over-voltage, over-current and short-circuit protection.
Brands: Corsair, Seasonic and be quiet! are benchmarks in PC power supplies with excellent reputation and warranty.
Every power supply in our catalog ships directly from Amazon, with official warranty and hassle-free returns.
Common mistakes when buying a power supply
Avoid these slips before you add anything to your cart:
Choosing by wattage alone: real quality, capacitors and certification matter more than the number on the label. A generic 800 W unit can be worse than a good 650 W one.
Not checking connectors: recent cards use the 12V-2×6 connector. If your PSU lacks it natively you will need adapters.
Cutting it too close: leave about 150 W of headroom over total consumption. A PSU pushed to its limit is noisier and wears out sooner.
Ignoring the 80 PLUS rating: it shows efficiency. Bronze or better wastes less energy, runs cooler and is usually more reliable.
Forgetting form factor and cabling: check whether your case uses ATX or SFX. A modular unit makes cable routing and airflow easier.
