With a maximum output of 1500W, this PSU can power a beast of a PC with multiple GPUs installed. A modular design with wrapped cables will help your build look minimal and sleek. There is also a 1200W version if you don’t need the extra 300W for your PC.


Before buying a power supply, you need to calculate how much power your PC will need. A power supply that can supply less than your power consumption will shut down the PC as soon as it overcurrents, damaging components. While there’s nothing wrong with buying a PSU that can handle more power consumption than necessary, overspending is likely.

Another factor that can change your choice is if a power supply is modular. A modular power supply allows you to plug in only the cables you need, while a non-modular power supply comes with cables attached.

The efficiency of a power supply determines the electricity consumption. If a 500W PSU is rated at 80% efficiency, that means it will draw 625W from the mains as 600W/0.8=625W, while the remaining 125W is simply wasted and dissipated as heat, which is where cooling comes in.

Considering all these factors, you can make your decision and purchase the best power supply for your build.
