If he upgrades to that 1080, he will not have enough power at 450W. That said, he can upgrade the PSU.

The Zotac 1080 I linked earlier is even smaller. How many watts is your current PSU?

Power Supply 450 Watt and my current GPU only uses 75Watt. Most of the new GPU's  use 300+ i guess.
Any recommendations? Need one that's better than the 1050TI Gaming 4G and doesn't use to much Power Supply

Is it possible to upgrade your PSU? There are many great PSUs under $60 or $70 for about 600W.

Hmm i will think about that. Are CPU and RAM sticks also using a lot of power supply? Or aren't they
