well, i had a similar problem (which means the same exact thing happened), where whenever i turned on specular, my computer would turn off. it turns out, i was so anxious to put my new grahics card in, i didn't realise my card had an extra slot that should be pluged in directly to the powersuply. my previous card didn't have said slot, so i thought nothing of it.
so yes, your card will still run without the A/c cable connected, but can't do specular effects.
any who, just check on that;i just checked online, and i see that your card does have an A/C slot so just make sure it's pluged in.
