im looking at buying a second hand APC smart-ups 1000. except it doesnt come with any cables what cables will i need to use it? and can i get these from a computer store?? im assuming i might need power cables with 2 male connectors for connecting the computer powerwise. and a five pin cable so the software can do its thing.. i attach a photo of the back on the unit its the only one i have on the computer at the moment i have seen the front and it looks in excellent condition. just not sure on the cable situation.
