Vdroop is a feature, not a bug :D. It is there to reduce power consumption of Intel CPU`s and for non ocers it is aboslutely no concern.
Another possibility would be a weak voltage regulator module...

Does not look too bad, apart from ugly cap brand choice i think it could be an ok unit if the price is right.

My Amacrox Free Earth AX500GLN (FSP OEM) is comparably anaemic, but it can hold up...

Solid polymer capacitors are in certain areas a very good choice, especially endurance in a hot environment is one of their strength.
Beyond that, their ESR, their ESL (in plain words their...

As long as the replacement caps are solid polymer ones, it should not hurt. If they replaced them with wet electrolyte capacitors, it certainly will affect your outcome.
Personally i do not like...

From theory it is simple, if your UPS does not deliver a real sinus, the PFC regulator will be disturbed.
But there are a wide range of semi sinus and near sinus waveforms in UPS.
May be the PSU...

A DOA is form my point of view no reason to reconsider a PSU decision.
This could happen with any brand.

A 400w PSu with at least 18A better 20A @12v should be sufficient, if it is a good brand....

I think synchronous rectification if beneficial at any voltage, as long as high currents are to be delivered.
And in todays PSU`s i think the currents on the 12v rail are long in the range, where...

It is good practice to add a fast Schottky diode in parallel to the MOSFET in synchronous rectification circuits.

This is to prevent the MOSFET`s slow body diode to conduct, which would translate...

The voltage stability of an resistor is not related to the power rating. Most low wattage resistors can not sustain a higher voltage then 60v to 100v. So they are not rated for AC lines or similar...
