My new Aurora R3 arrived today and I have a rather serious issue. Apparently I screwed up and only ordered the 525w PSU instead of the 875w PSU. I can not figure out how to buy one from dell and their outsourced phone support is less than worthless. Does anyone know of either how to buy the alienware 875w one or of any other PSU that can go in the case without having to mod it? Obviously I'm not modding it and voiding the warranty, but I am VERY afraid something is going to burn out. Any online wattage calculator I've tried all say the mininum PSU should be well above 525w. So if anyone can help, please do.
