They replaced my 13900k after about a week of back and forth with their support department, after getting transferred between like 5 agents for some reason. It took a lot of patience to get through that process. RMA took 3 weeks. I bought a $150 i5 so I could still use my PC. I’m not sure how much faith I have that the new one won’t fail as well.
That said, the amount of troubleshooting and wasted time that it took to figure out that the CPU was responsible for months of random crashes while gaming was frustrating, to say the least. Even a complete refund would barely dent the cost of my wasted time. My next PC will be rocking AMD.
