Power supply question for a friend.

[Dreadbeard]

My friend is looking to build a computer, everything like mobo cpu gpu and all that i know enough about. But PSU comes a little bit more of a struggle.
Is this one a good PSU for the money?

He only will run a single GPU .

Awesome thank you!

Quick question for my self. Where could i get some nice RAM? i need to push from 8GB up to at least 16GB, should i pay for vengeance? or is there other better / cheaper ram?

Mixing ram is hit and miss you have a 50\50 chance of it booting. Even identical modules purchased at separate times can be incompatible.
