Our recommended power supplies will happily provide more than enough power to your cryptocurrency mining PC. Whether you want to start out small with the EVGA SuperNOVA 650 G+ or go all out with the be quiet! Dark Power Pro 12 with its impressive 1200W capacity and 80 Plus Titanium efficiency rating.
Not all power supplies are built equally, which makes it a little more challenging to pick the best PSUs for cryptocurrency mining. Unlike most PC builds, a system running mining software with one or more GPUs is going to be a considerable load on a constant basis. The most important factors to bear in mind are as follows:
- Double the capacity of your GPUs combined.
- The higher the 80 Plus certification the better.
- Ensure it has all the most common protection features.
- Enough PCIe and Molex connections for all your cards and risers.
- 105C rated capacitors with other high-end premium features.
One shouldn't save too much money with the PSU to ensure the reliability of the PC as well as to make the most of the graphics cards you manage to find available. Purchasing a PSU from a reputable brand should be a good place to start.
