Is there really a difference in Intel and AMD approved pow..

Archived from groups: alt.comp.hardware.homebuilt,alt.comp.hardware.pc-homebuilt (More info?)

I put a power supply that I had lying around the shop in my computer ( My
400w started to act funny ) When I bought the last one I made sure that it
was AMD approved and It worked well in my system till it gave out. Needless
to say I did not make sure this 350w was AMD approved and sometimes when the
system boot up it stops when counting up the memory and freezes. I am 99%
sure that the power supply is the problem but just for personal knowledge
what is the difference ?

Are you sure that it's not approved by either company? Because they
quit listing individual PSUs and now list only manufacturers.

All I know is that a lot of very bad PSUs are approved by AMD, Intel,
or both, including Deer's (Codegen, Allied, Logic, L&C, and about any
brand with an animal name), and Deer makes some of the worst PSUs you
can buy.

I've also learned that you can't trust mobo voltage reporting at all
and must check voltages with an accurate meter (digital) to know if a
PSU is working well or not.

Even then you may be up the creek. I just finished working on a system
where the problem was the power supply. Had 350 wt ps in it. All voltages,
measured at the molex connector, when it was plugged into the motherboard
and turned on, measured within specs, yet it couldn't boot the system. A
cheap 250 wt spare I had in the parts bin booted it perfectly every, so you
can't tell just by measuring the voltages either. Well, you can if you get
a bad reading, but all good readings don't mean the ps is good.
If I have it figured out correctly, thanks to Ric in another NG, the RC
circuit regulating the power ready voltage wasn't rising fast enough. With
out a scope you can't detect that. If it comes up too slowly, the system
won't boot.
