What PSU do I need for my PC?
Many modern gaming systems with a 6 or 8-core CPU and a midrange to high-end graphics card should get by with a 650W to 850W power supply, with 750W being a long-time sweet spot for gamers. More powerful hardware requires higher wattages, especially if you plan on overclocking.
How big of a PSU do I really need?
But even with several hard drives and a decent Intel or AMD CPU, a 750W power supply is sufficient for most single GPU configurations. For multi-GPU systems, we typically recommend at least a 1000W or more. If you’re unsure of the best PSU for your config, we recommend using an online PSU calculator.
