Question Repalce Power Supply Along With Motherboard?

[golfluvr]

Something has burned on my motherboard. I believe it is the VRM heatsink. I have an MSI X99A Tomahawk with an Intel® Core™ Processor i7-6800K Six-Core 3.40GHz 15MB Intel Smart Cache LGA2011-V3 installed.

Could the power supply have caused this or should I just replace the motherboard? What is the best replacement board for my gaming PC?

What PSU?

The power supply is 800 Watts - Standard 80 Plus Certified Power Supply - SLI/CrossFireX Ready. I bought the computer 3 years ago from cyberpowerpc.com
