I received a new Asus R9 290X today and installed it into my Area 51, replacing my HD5970. My Area 51 has a 1200W power supply, but I think that I am having a power issue. The PC starts up fine and will run on the desktop and browse the internet, but as soon as I put a gaming load on it, it blackscreens and locks. I have found that by using different combinations of PCI-E power connectors I can extend the time before the PC blackscreens and locks; the longest time is when using the P17 and P19 connectors, but even this is only about 5 seconds. When using P16/P17 or P18/19 it crashes almost immediately. The old card (HD5970) was using P16/P17. The cards stated requirements are 12V/24A on the PSU with a minimum of 750W. Is the Area 51 supply not capable of providing this much current, or is the motherboard not providing enough through the PCI-E lane? Or is the card just possibly bad?
Thanks in advance!
