hello, I have a thermaltake 550w psu and it only has one 12v rail but, my new 990xa-gd55 motherboard needs 2 12v rail, but my computer runs. The cpu fan gets extra loud and the and temps start going up when playing any game. my old setup with 4400+ work fine with this psu and my 550ti. basically i'm wondering if i need a different psu? or if it would affect annything not having the other 12v rail plugged in. it also takes a long time to boot compared to before.

Please elaborate...Where did you get that information??I couldn't find anything regarding two 12v rails in MSI website.
Also a PSU having single powerful 12v rail is better than multi-rail 12v PSU of same wattage.

so the psu only has 1 4 pin 12v connector and the motherboard requires an 8 pin connector or at least that what i think. Everything is new. my spu fan speed goes up into 5500+ rpm range and doesnt seem quite normal. My videocard also seems to get hotter than before when placing my hand on it compared to when using my old asus micro am2 motherboard.

my new setup is

990xa-gd55 motherboard
phenom 2 x4 975 @ 3.6 ghz
8gb 1866 g- skill ram
evga 550ti 1gb ddr
thermaltake 550w from 2007

If your power supply has only a 4-pin ATX 12V connector it should still be fine. If your power supply unit has an 8-pin EPS 12V connector then use it.
