While one of the most overlooked components of a PC build, your computer’s power supply unit is one of the most crucial elements for creating the ultimate setup. But why? One word–reliability. The reliability of a system isn’t taken into account when building a PC. Sure, it’ll work fine initially but you’ll certainly run into some power draw issues down the line, resulting in some serious damage to your hardware components in the worst-case scenario.

Modern power supplies have safety implementations that ensure your PC components aren’t cooked or the power supply itself doesn’t go bad in case the AC from the socket goes haywire or if you’re experiencing blackouts on a stormy night. Therefore, buying the right power supply for your PC is quintessential to ensure the safety of all those expensive PC components. Corsair is one o the go-to PSU brands for a lot of system builders, catering to a range of budgets and system requirements.

Do I need a new PSU for modern graphics cards?

Some new GPUs feature a 12+4 pin setup dubbed the 12VHPWR PCIe 5.0 connector that ensures the GPU gets power anywhere from 150-600 watts. That’s a massive bump from the normal 6-pin and 8-pin PCIe connectors that sent out only 75 and 150 watts to most GPUs of the time. The ATX12V v3.0 spec was introduced by Intel on February 1, 2022.

This new ATX 3.0 design states that any GPU with more than 450W of power should include the new 12+4-pin setup. The new ATX spec allows the PSU to set the power limit of your graphics card, which means that investing in the right PSU for your GPU is very important moving forward.
