Buying Guide
When picking a power supply, you need to match its wattage to your PC's components, especially your graphics card and CPU. For compact builds, the SFX form factor is crucial to ensure it physically fits your case. Also, check for modular cabling to keep your build tidy and improve airflow, which is extra important in smaller enclosures.
wattage
This number tells you the maximum power your PSU can deliver. Think of it like the engine size in a car; too small and it won't power everything, too big and you're paying for unused capacity.
form_factor
SFX means it's a smaller size than standard ATX power supplies. It's like choosing a compact car over a full-size sedan; it fits in tighter spaces but might have fewer features or be more expensive per watt.
80+ Gold
This is an efficiency rating. It means the PSU wastes less electricity as heat, saving you a tiny bit on your power bill and keeping your PC cooler. It's like getting better gas mileage in your car.
Native 12V-2x6 Connector
This is a direct cable for modern, power-hungry graphics cards. It's like having a dedicated fast-charging port for your phone instead of relying on a slower, older adapter, ensuring stable power delivery to your GPU.
Alternatives
If you need more power or a standard-sized unit, search for ATX form factor PSUs with 850W or higher ratings.
