My requirements are an Intel i7 5th generation processor with a GTX 1080 graphics card and 8 GB of RAM. I'm a complete beginner when it comes to creating a gaming PC. Which power supply would be best for these components, please?
The http://Corsair RM650x is a high quality fully modular unit that comes with a gold certificate for efficiency. Its power is more than enough for the system you have described and it is priced fairly cheap. And last but not least, it is built well. Way, way better than the one you have mentioned you have in another thread.
