I just put together a new x58 system w/ i7 920, ex58-ud3r gigabyte board and 6 gigs ddr3 ram. I installed everything carefully, and tried to boot for the first time but no display (bios or anything, it just idled red like it wasn't getting a signal). I noticed it recommends 2x4 12V power, i just have 550W with normal connections- could power be my issue? the video card was just pulled from a working system (9800gt). Not sure where to go from here, any feedback would be excellent.
