Don’t worry bud I got a high rated 600 w psu and I bought the Radeon 4gb model as that just needs the six pin connector and as I only want to play Skyrim and fallout modded it’s perfect for what I need it for thanks for replying much appreciatedto be honest looked online at the PSU and would not trust that PSU with 4gb or 8GB version its an really cheap PSU never heard of the brand checked amazon ratings are poor with bad feedback and if that PSU fails could take out your computer parts with it!
