HELP please installing power supply


P

PawsForThought

I have a Biostar M7VKB motherboard and an Athlon T-Bird 1 gig megahertz
processor. I had a 250W power supply that died so I got a 400W PSU to replace
it. Here's the problem, before I installed the new PSU, I looked at every
connector from the old PSU and saw it was connected to my CDRW drive, my DVD
drive, and my hard drive, and the MB. That was it. So, I installed the new
PSU but unfortunately none of the connectors were marked P1,
P2, P3, etc. So, I had no idea where any of them went. So I took the
connectors that had 4 pin holes and connected to my CDRW, DVD and hard drive,
then I connected the one to the MB. Then I closed up everything and powered
up. So far, it was sounding good. However, my monitor will only stay in
standby mode and the screen stays black. I have absolutely no clue what I'm
doing wrong. Right now I'm on my old HP pentium and the monitor works with it,
so I know it's not my monitor.

Any help would be greatly appreciated or if anyone knows of any website that
would have information to help me.

All the connectors that have the large 4 pins (type like the hard drive) can
be used on any device that matches. They are all wired together inside the
power supply.
They are keyed so they are difficlut to install backwards. The larger
connector should also be keyed so it can not go on the motherboard
backwards. Look for some loose connections on the vidio cable or card.

Thank you to Ric and Ralph Mowery. It turned out I got a bad PSU and exchanged
it for a better brand and now it works great.
