Can't find much on it but it looks like a really low quality unit with 2x12v rails at 14A and 16A. That's really weak for a claimed 500w PSU. Technically it is enough but I wouldn't spend good money on a high quality GPU and run it off a low quality PSU. Any tier 1 or 2 500w or greater on offer near you would be a worthy upgrade http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html
