Must Read: Best Budget Power Supply (PSU) for Graphics Cards Top Gaming Power Supply for High-end Graphics Cards So here in this post, I am going to list down some of the best power supplies for gaming PCs with high-end graphics cards. The maximum power consumption of a reference or Founders edition GeForce GTX 1080 card is 180W which means you need to have a minimum of 500W power supply to fully support this card and if you put two GeForce GTX 1080 graphics cards in SLI mode then your maximum graphics card power consumption can shoot to 360W and you will require a 700W or higher PSU to power your gaming PC. In the case of a multi-GPU setup, the PSU should have enough 6-pin and 8-pin PCI-E power connectors to provide sufficient or adequate power to your graphics cards. For such power-hungry PCs, you need a power supply of 600W to 700W in case of the single high-end graphics card and for SLI and CrossFire Multi-GPU setup you need around 750W (or maybe higher) PSU. So to be on the safer side you must get a powerful PSU for your high-end graphics card or graphics cards in multi-GPU configuration ( SLI and CrossFire).Ī typical high-end graphics card can consume around up to 180W to 300W (or maybe more) of power and if you have multiple high-end graphics cards in SLI or CrossFire mode then the power consumption will get doubled or tripled depending on the number of graphics card you have in your ultimate gaming PC. If your power supply or PSU is underpowered then one or more components also have chances of failure, particularly the hard drive, and then you will be at a huge loss. This is because if it does then you will experience frequent restarts and may also end up burning your power supply. Cooling Type: 120mm Sleeve Fan (2000rpm, 74.48CFM, 29.If you are building a high-end gaming PC with a multi-GPU setup or upgrading to high-end graphics card then you will definitely need a powerful PSU so that your graphics card and other PC components will work normally and never fall short on power.
