Compaq Presairo SR2050NX Motherboard died

Compaq Presairo SR2050NX Motherboard died, and e-bay had a RC410-M
rev:1.1 listed for $34 US Dollars...

Just got it today, installed the CPU, Heat Sink/Fan applying a bit of
Arctic 5. Booted up WinXP after checking the hardware with SimplyMepis
8.

The only anomaly was two dialog boxes indicating I had recovered from a
serious error send the report to Microsoft.

I am doing a virus scan now, seems to be more than a few Trojans, and
more tracking cookies than I have seen in a long long time...

I tested the Bestec Power supply (Model ATX-300-12z Rev.:CDR S/N
0608S2029089) not a stitch of voltage on the P7 plug. Looking over the
motherboard carefully I found only one bulging cap near the end of the
Video card slot.

This system is almost dust free, and that was the only visible malady I
could locate on the Motherboard. A good cap student could repair this
motherboard removing the cheap caps, and putting some quality units on
the motherboard.

I realize this computer has been used much longer than the warranty, but
there is no reason HP, eMachine and Dell kept assembling computer systems
using Bestec and Delta power supplies without any circuit protection.

They all should have their pocketbooks taken apart for all the troubles
this fatal bean counting greed has cause computer users for years...

You're right. No reason to ship computers with crapola power supplies
lacking circuit protection. You've seen this with Delta power supplies?
I'm mildly surprised, because Delta always produced good quality
stuff. But that was before overall computer product quality got flushed
down the toilet by most of the name-brand companies. You've seen
Bestecs in Dells? Not as original equipment, AFAIK.

Anyway, HPaq, Acer-eGateMachines (let's use their real names ;>) and
Dell do not assemble many of their computers. Instead, contract
assemblers do it out there on the Pacific Rim, the same place where the
poisonous baby formula and toothpaste are produced... Ben Myers

Hi!

Sounds like it worked out better for you. I had someone come to me with an
S4020WM system that died during a particularly nasty power failure/recovery
cycle. They wanted to save it, so I bought a motherboard from eBay and the
seller sent it in a posterboard-thick box with no padding. That board never
had a chance.

I saved the case since I liked the design and thought it seemed well made,
put a HiPro 350 watt power supply in it and a Biostar P4M900-M4 motherboard
in there as well. I have no shortage of S478 processors kicking around, so a
2.53GHz Celeron topped things off.

Odd, I thought the Bestec 300W supplies were better, and at least had
overvoltage protection in place. The earlier 230/250 watt units did not.
I've never lost one of the 300 watt units. You could do worse, although the
pictured supply didn't blow anything up:

Delta and Bestec aren't in even remotely the same league. Delta produces
high quality power supplies and has done so for years. I don't think that
Bestec even has a web site.

So far, I haven't seen a Delta supply come with any Dell product outside of
a laptop. The supplies that I've seen were made by Lite-On or Astec Custom
Power. Lite-On, despite their suspiciously cheap products, actually seems to
do a pretty good job.

William,

The Presairo SR2050NX that I took apart came with a bestec power supply.

HP part #*5188-2625* It was still in the recycle barrel...
