I hardly have any room for any lol. I don't know wether I should buy a PSU yet. I have a damn a propriety psu that has a 3 pin connector for the fan. Are their ways around this. My uncle also has a sony. His psu just died and he told me that we have to get the psu's sony gives us and he's really mad about it. Besides having very small room in the case for a diffrent psu theres custom psu's require us that we can only get new ones from sony if we want the fan to work.

you can always modify the fan connectors, although that'll require some basic wiring skills....

Yeah, he lives across the ocean and he's making a big deal about it. Why is it connected to the mobo to power the PSU fan or the mobo fan? He told me he'd try to look for a psu to buy him before I fly over their and because of sonys small psu's will have to leave it outside. Do most psus have a 3 pin connector to most mobos. Or is this another diffrence in sony psunits.

Most mobos have 3pin connectors for fans. However, 3pin input to mobos is just about unheard of I guess. But all you need to do is to change the plug, and make sure you got the right voltages in the right points. Not very hard IMO, but I've done stuff like this before. Just need to get hold of your m/b layout.
