Put my old motherboard back in (Gigabyte GA-880GM-USB3L), I could run the power supply stress test just fine (left it only 2 minutes). For some reason the CPU temps are much hotter with this Phenom 2 955BE.
Will contact Asus tomorrow about to get the RMA process started.
Here's an image of how it would look when I get through the psu stress test:
I had some time left so I called Asus support here in Mexico, apparently the first time I called they made a mistake because the warranty is regional. Looks like I'll be having to send the motherboard to the United States. I will call next week to see how I should proceed with this.
