hi guys, well i bought a new ECS motherboard, i thought i could use my old case with it's PSU, it's max output is 305w, and has 24 pin, and 4 pin, but is making an strange noise when is plugged into the motherboard, i don't know if it is an issue with the PSU, or the motherboard, i can only think that since i bought the old PSU in 2005, it is out of date of the output is not enough to work with this motherboard, so my question will be if it is that or you think that i screwed the installation :c

Im using Motherboard: ECS A75F2-A2, CPU: AMD A8-5600K Black Edition and RAM: 4gb, is just a quick and cheapiest solution for my brother so he can keep on gaming :p, but i just was wondering if that noise and why it does not turn on, could be because the PSU is so outdated?
