I've just removed my power supply (ACE 580 UB) from my motherboard as I have a brand new motherboard. Problem is I've notice the orange wire connections (Pin 1,2 & 11 - I think) look blown (burnt). Would it be safe to use this same power unit on a new motherboard ? Itwas working last time I tried it

The top wire at blower motor is voltage, the bottom wire is ground. So brown wire is voltage, orange wire is ground. So, the resistors, havc control, on and off and speeds are controlled on the ground circuit. Generally if ground is good, no voltage or very little on the ground circuit, because the component is using the voltage. The wire connector for your blower motor is it any good? You could remove blower motor, use jumper wires off battery for voltage and ground, the blower motor should run up a storm. It wouldn't hurt to use inline fuse, just incase.
I looked at info for 3.5L, my info didn't show 5.3L?
The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

A Blinking Amber or
Yellow power button means that the power supply is receiving power from the
source but is unable to properly distribute it to the components. This can be
caused by a defective power supply or a defective motherboard. Just to make sure
that nothing else is causing the problem, remove any PCI cards like modem,
video card, sound card, etc... Remove the memory modules and disconnect cables
to CD/DVD drives. Look at the USB ports to see if any are damaged.
I always start with the power supply. Your power supply may not be producing all the power your motherboard is requesting, even though the light on the back is on. If you dont have a power supply tester, then you can try removing your power supply and trying a known working supply in it, making sure you have the right connectors on it for your motherboard..
I looked at a pic of your motherboard Asus A8n-vm and I dont see an orange (or any) button to push. Was that to reset your bios? If so, unplug the system from the wall, and carefully remove the battery from the motherboard. While it is out, push the power button on the front of the computer a few times. The computer wont start up, as you have it unplugged, its just to drain the motherboard of power to reset the bios. Then reinstall the battery, making sure it goes in the same as it came out (- is usually down and + is up). This should reset the bios info to the factory settings.But I still think it is a faulty power supply.
All the wires from the power supply are power connectors, depending upon the motherboard not all power connectors from the power supply maybe required. If there are no matching sockets on the motherboard, then that power connector is not required.
