I was just wondering because I need a new power supply for my computer. It is an Acer Aspire AM3910-U4012. Is the power cable that connects to the motherboard the only power cable I need to replace or will I need to replace all the cables in my computer for it to work properly?
It will come with an all new set of cables! You should continue to use the cables that you have installed already, and save the new ones for later. You never know when you'll need to replace one, or when a friend might need one from you.
You probably won't have a choice. The power cables on the supply in your computer are permanently attached. You'll have to remove them when you take out the old power supply. - Dominic
It will come with All New Cables
If your current power supply is modular and you buy the same brand of modular power supply to replace it, then you can use most of the existing cables, if you want to. For most power supplies, all the cables are permanently attached. But there's nothing wrong with using existing cabling if it is modular. You have to be aware that different brands of power supplies use different types of modular cables, though. If you change brands of power supply, most likely you will need to replace all power cables, regardless of if they are modular or not...
