I'm installing a new PSU, replacing an old 580w w a Silverstone 1000w st-g. The pc i bought was prebuilt and has some case fans and lights to worry about. In addition to a few confusing things (like a light and battery pack looking thing at the bottom of the case that have never seemed to work) I'm a bit confused by the way the fans were set up.
My motherboard is an MSI p45 Platinum and it has a 4-pin out called JPWR which I believe can provide power to video cards, according to the manual PDF for the mobo. But when they built my PC, it looks like they used this to start a daisy chain of fan power. It splits to a Y, one to the back exhaust fan and one to the female end of the side window case fan, which then males out to a 4-pin connector I can't see behind the drive shield wall, and then looks like it comes out of the other side of the drive shield wall and connects to a molex for the front chassis fan and possibly what looks to be another one for the front chassis light.
So I have a couple questions.. #1, to use JPWR to power all of the fans, as it looks like was the original setup (none of the SYSFAN ports on the motherboard were being used and still aren't) ... how is that different from the more normal either fan->psu direct, or fan->sysfan setups? should I try to emulate this with the new PSU setup? And, I know it's random as topics go, but is it safe for me to take off the OTHER side of the case (non-window side) without doing anything untoward to the mobo, which is of course still in place in the pc? That way I could see the wiring jumble that's behind the shield wall, BUT I don't want to take the chance of damaging anything as this is my first time doing this sort of thing and I've already had to bang my knuckles a bit into the edge of my video card, remove and replace a ram chip just to unhook the old psu.. any answers or ideas? thanks a lot btw people like me would have no hope without places like this
