This is a record of my newest, starting with my first 80+ model, and not 
including
any that came with any PC acquisition:

All are used with single CPU motherboards, roughly half with IGP video, none 
with
discrete GPUs that take 2 slots or require separate power connection, and only a
very few GPUs with active cooling. Maximum HDD/SSD count is 3 per, but most have
only 1. Thus, my PCs' power requirements are relatively modest. Maximum CPU core
count per PC is 6. Max CPU TDP is 125W, in one only (running on a 430W). All the
rest are 85W TDP or less.

Nearly all those I bought before 80+ eventually required recapping within 5 
years
of age, or warranty replacement. The EA500 was returned because it always shut 
the
PC down during UPS transition from 120V to battery. 2 of the other Earthwatts 
also
needed recapping.

AFAICT, I've never overloaded a PS that wasn't itself failing.

Since dual 12V rails became a thing, I've always avoided such models - KISS.

I buy on sale rather than immediate need. So, my cost has typically been in the
$20-$30 discount (or rebate) off regular price range.

I generally find:

Seasonic
EVGA
Corsair

to make reliable power supplies. I can't speak to AC supply
problems, because I always put any computer I care about
behind a UPS.

The Seasonic S12III series has several units in the $50-75 range
according to required power.

Really? I've used a number of cheap Chinese 300-400W power supplies in the $20 
range and they all worked for years without any issues.

I am starting to worry that $60 PSU's are good for one thing -- 
destroying themselves and everything else in the computer!



Any recommendations for an ATX power supply for a single-socket server/ 
workstation?  Cabling should include 24-pin motherboard connector, 8-pin 
CPU connector, 6-pin video card connector, several SATA power 
connectors, and a few 4-pin drive connectors.  The PSU must reliably 
detect AC supply and/or computer load problems, turn itself off when 
they are detected, and survive A/B troubleshooting under adverse 
conditions with faulty components?
