It arrives tomorrow, and I'm wondering is there any specific things I should be doing when removing the old one and installing the new - so I don't electrocute myself or fry any componentry etc. When removing the old one, do you leave the cord plugged in to the wall (wall switch off) for grounding etc?? What stuff do you connect up first? Some step by step instructions would be great :) Cheers!	PoWa (203)

And the molex connectors from hdd/cdrom etc. Order doesn't matter aslong as the PSU is off. - Undo the 4 screws holding the psu in. don't let it fall. - Screw in the new one. - Start connecting wires. Again order doesn't matter, just make sure its OFF. Enermax specific: - Be prepaired to spend a bit of time fighting the mass of cables. Now would be a good time to get some cable ties. - Find somewhere hot to put the temp sensor. I have mine jammed in the cpu heatsink. - Connect the 3-wire fan cable. Preferebly to the motherboard system fan connector, otherwise use the adaptor included to run it off a molex.	bmason (508)

Nice and quiet too :) Those big copper shielded cables are blimin difficult to deal with :\ had to bend n twist etc. Hardly got any room in my pc left! :p I do have some extra cables that I have no idea what to do with at all. Apparently there is one that connects to the motherboard (real small one with 3pins) Well I found a slot on the motherboard that it kinda fits into. Can't see anywhere else it could go :p Does it really matter where? Also it says that one of the fans is controlled by the motherboard. Where and how do I do this? Theres a 12V cable and AUX cable, that are separate from the other mass of cables because they have their own copper shielding thing. What do I do with these ones? There weren't those cords on my old PSU? Finally 'Temp sensor' ?? Where ? Whats it look like? maybe I didn't get one :p	PoWa (203)

If you have a small case they must have been terrible. > I do have some extra cables that I have no idea what > to do with at all.

If the external fan is spinning its in the right place. If its not, fix it NOW. The internal fan is controlled internally. > Also it says that one of the fans is controlled by > the motherboard. Where and how do I do this? As above. > Theres a 12V cable and AUX cable, that are separate > from the other mass of cables because they have their > own copper shielding thing. What do I do with these > ones? There weren't those cords on my old PSU? The 12V cable is for P4 boards. AUX is for server boards. Just jam them some where. I used a cable tie to bunch them up near the PSU. > Finally 'Temp sensor' ?? Where ? Whats it look like? > maybe I didn't get one :p Its a short cable (~20cm) that comes out with the other cables. It has a round [green?] thermal resistor at the end.	bmason (508)

It has a round [green?] thermal resistor at the end. I honestly don't think it has one? I'll have a look at the website again..	PoWa (203)
