Are you sure it is the PSU squealing and not your 285's?
Yes, I took the psu out and used a tube to verify. HOWEVER. I solved both this squeal and the instability by making my GTLVREF lands EQUAL just right now.
Per this article, the Auto setting puts Lane 1 at +25mv which was causing the issue. I just put mine at +0mv and am running both prime95 tests, furmark, and atitool with no artifacts w/no noise or locks.
To think I almost bought a 860W supply.
BTW per my rig below, I just re measured total power draw during this load and got ~650watts. My SPP is at 55c as well. Is this ok? Would that intel fan help?
