Hi wolfwiser,
As
dai suggested, that PSU might not be good enough for your needs; so go to the 'Power Supply Calculator' link in my signature, and assess the recommend 'size' that you really need; not forgetting to had 30% for performance.
Your CPU could still be faulty and the fault might not show up until it has been in operation for a while.

Time will be the deciding factor with this.
In all probability the Graphics Card could have suffered in that 'frying' too.
Understand that your 'old' board had a pretty dramatic 'burn-out', going by the photos in that other thread, and it is quite possible that other component were 'taken out' with it, so it will be a process of elimination.
Even though you have successfully got Windows® to start, does not necessarily mean that all your woes are over.
Please re-read the other post that
dai gave you, and follow his lead to determine the cause.
Post back with the results.
