I am building a computer in an antec sx-1030 case with four 80mm fans. My mobo is an abit kg7-raid with a amd 1.4Gb. I also have filled up 8 of the 10 drive slots in this case. My question is will the 300w power supply in the case be enough or will I need a bigger one(like a enermax 431w or 530w). I also plan to have two blue orb fans (chipset and video) and I want to overclock this machine.
