Hi everyone! I've currently got an 8800GTS 320, and I believe it is connected to my PSU using a single power connector. I'm afraid I'm inexperienced when it comes to connecting new hardware up to my PSU, but I want to upgrade to an ATI 4870 1GB and I hear it needs two connectors to my PSU. The question is: will I be able to connect the 4870 to my PSU? I.e. could my PSU support the two connections required? I think my profile has all the information you need, and here is the link to the PSU specs: http://www.compucase-hec.co.uk/psu_arctic_power_500-600-700.htm I'm hoping someone can help me because, although I realise the website shows what connectors the PSU has, it doesn't make a huge amount of sense. If anyone could explain it I'd be eternally grateful!
