Stop using Furmark.
While Furmark isn't usually recommended to be used, it DID help the OP prove that his old PSU was dying. So it did its job for its intended purpose--stress testing.
While furmark is the prime95 for GPU's, both prime95 and furmark, when used properly, can help expose borderline or flaky hardware. That's different than using prime95 (in AVX virus mode) or furmark to determine if your high overclock is stable or not.
I'm with the OP on this.
