20 to 24 pin power supply

I have an acer amd box with 24 pin connection on the mobo but my 450W power supply has a 20 pin connection. local store says go ahead use 20 pin as it does fit and everything will be fine. I am sceptical that it will work has anyone else had experience with this issue.

 

i would up grade ur power supply i did exactly what your going to do and it fried my power supply bought another 20 prong one, conneted it , and it fried. so i asked a friends dad where i get most of my computer knowledge from, he took a look and that was it, so i would find out wat kind of mobo u have and google it to see what kind of power supply is wanted, before u go skrewing stuff up. if it help sweet if i just rambeled on what ever , but i hope u figure it out before u mess it all up. good luck! =D

 

I have successfully used a 20pin power supply with a 24pin motherboard without any negative issues, but I don't really recommend it. Yes, it will work, and you may never experience any issues, but the other 4 pins are there for a reason, and if you really start putting a heavy load on the PC, you may experience some instability and crashing. Adapters are available that will work, and I have also used these without any ill effects, but some people claim that the adapters are actually worse than just leaving the 4 pins unconnected. I don't agree with that, or see how it makes sense, but that's what I've heard. The best solution is to purchase a new 24pin power supply.
