Hi, Travis:

Would you double check the PFC and PWM MOS, mostlikely PFC MOS have more stress than PWM MOS.

Well that's hell of a long report to read...

Output regulation was Superb on all rails except -12V. Minor rails are very stable.
Efficiency was Good especially at loads up to 50%. The efficiency at 115VAC 100% load being only 83.3% disappointed me, but this is expected for a 80+ Gold design cut down to Bronze.
Ripple was Low on all rails, lower than what I've seen with 750W/850W PUQ-G(Gold) units.
No actual data in sync dynamic tests, so no info besides the unit passed those tests.
Finally, the cycle dropout test was performed under 80% load 115VAC 60Hz, and the starting phase was 90 degrees. The unit endured through 16ms dropout.
