Alright, I opted for the single 280 over 2 260s in SLI. Got my adapters in, blah blah, green light shows, but heres the thing, even with my Mobo video disabled, only the mobo will display, because it wont even recognize that the 280 is even inserted into my computer. Green indicator light is on, fan runs nice and quick, 6 and 8 pin are plugged in, but no cigar. I have a 600W Cooler Master PSU which I know is kind of just cutting it, but none the less. I called BFG and they said that maybe its just not enough power though even on their records a 600W suffices. I am REALLY not wanting to go and purchase a new PSU *AKA I'm pretty broke 🙁 * but I was wondering if anyone has had an issue with it recognizing a 280 on an Asus M3N-HT Deluxe MOBO. If not... Anyone want a 600W PSU and an Nvidia 9500GT in swap for a 800W+ PSU
