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. This is because if it does then you will experience frequent restarts and may also end up burning your power supply. 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. 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).
A 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. 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. 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.
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. 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.

Final Words
So if you are building a high-end PC with a high-end graphics card and other components then don’t forget to invest in a good power supply. Above I have listed all the best and most reliable PSUs for all budgets and capacities ranging from 650W to 1000W+. For a single high-end graphics card, a 650W PSU is more than enough but if you want to build a multi-GPU rig then you should opt for a 750W or higher power supply to be on the safer side. If you have any queries regarding graphics cards, gaming rigs or PSUs then feel free to ask me by leaving a comment below.

Mr. Verma,
I have a Dell Optiplex 3020 and am adding a Radeon Sapphire RX 570 video card, so that I may run 4 monitors. I’m attempting to identify the correct 650W power supply that would provide me with both 6 pin and 8 pin PCIE connector cables. Any suggestions?
Thanks!
Is this a SFF variant or a standard one? By you mentioning RX 570, I think it is a standard one and for this I would suggest EVGA 650 B3, 80 Plus BRONZE 650W, Fully Modular Power Supply. It is a very good PSU and comes with 3 x 8-pin (6+2) PCIe connectors.
Akshat,
Thank you so much for your prompt reply. Very much appreciate your insight and time.
You were truly very helpful!
Thanks for the appreciation!
I have a HP Prodesk 600 G1 twr computer with and trying to play ths new MSFS 2020 with a min req’t of at least a RX 570 or GTX 770. my power supply is 240W. I put in a GTX 1050 Ti and the computer won’t boot up. The GTX 730 Boots but won’t play the game saying the GC over heated or over clocked. Do I need more power?
You need a good 450W PSU for these graphics cards.
