I have had an Antec BP550 Plus running my Pentium 3 815EEA2 system 24/7 since Feb. 2017.
It ran a Northwood Pentium 4 system for a number of years before that. No complaints so far!

Sounds like a pretty good PSU, used Antec in the past and they were pretty good. I'll look into this PSU.

Thank you.

I am running this PSU on my d815eea2 board, with an P3-933 and have run it with various Geforces from 2 to 4 and even Radeon 9800xxl from Medion. http://www.antec.com/product.php?id=705370&pid=53&lan=nz

I've used 2 systems based on a D815EEA, one with a 800MHz Coppermine and another with a 1GHz Coppermine. I checked but both systems are upstairs and I was wanting to get into bed instead of digging around in the attic 😜
Iirc both used some FSP or FSP derivative, the 1GHz probably used some 300W with 30A on the 5v line and 10A to 15A on the 12v line (could've been an AOpen branded or even a Zalman branded PSU) and the 800MHz could've been using a 250W FSP or Powerman branded PSU, though I'm not really sure what PSU it used.
The 800MHz system lost its main purposes after I had moved so I'm not even sure if it got disassembled at some time. The 1GHz system hasn't been used in a while but hasn't been disassembled.

+1 on the BP550. I've used on my daily driver since 2012, thing is built like a tank. I dropped it from 5 feet and the dang thing didn't miss a beat.

I guess when it comes to old builds the PSU generally is the hardest and at least for me the most worrying part of the entire build. I start seeing high ampage on the rails and think it's probably not good to deliver that much to the PC. Learning a lot though which is good.

Has a pretty beastly 32A on both the +3.3 and +5, and 36A split between 2 +12 rails
Got mine on Ebay brand new less the box for $20 shipped.... they seem to be pretty common on Ebay for cheap

Have it running an Athlon XP 1800+(Palomino core), with 2 sticks DDR RAM, an ATI Radeon 9600 XT, PCI Gigabit Ethernet, 2 IDE HDDs, an optical drive and a floppy drive.
handles it all with no sweat.

It's a really well made and high quality power supply that so far I'd have to say I'm really impressed with.
