A surge protector is designed to protect your system from surges from the wall outlet surges to your system.
A quality power supply has built in high and low voltage and amp protection BUT when a power supply goes up in smoke those protection could be damaged and the surges from the power supply could enter the rest of your computer.
They most likely did.
Burnt smells from the motherboard is a BIG clue.
I had a very long time ago had the same problem you had with a power supply.
I put a new power supply in and booted a few times. Then piece at a time things just started going bad. It only took a few days.
I ended up just building a new computer using a quality Corsair top of their line power supply. A power supply is no place to try and save money. Many members are also have good luck with EVGA Gold or higher.
