On Power up:"Power Extension Cable Not Connected to your Radeon 9800"
When I powered up my pc this morning, there was an alarm beeping and a message on the monitor that read "You have not connected the power extension cable to your Radeon 9800 card. Please see instructions on how to connect power cable"
 The pc was running fine the day before and it shut down properly last night. I did not touch the tower at all so nothing could have been jarred loose. I took the cover off the tower to check the connection to my 9800 to make sure and the power cable was already firmly connected. I saw nothing wrong with any of the wiring. I powered the pc back up with the cover off to see what would happen and the pc booted up properly. The fan on the 9800 was working fine. I don't know what happened.  Is this a warning sign that my pc did have not enough power when it was booting the first time? I have the Intel Active Monitor running for my MoBo and I do get the occasional alert that "voltage has gone outside recommended range" but it always returns to the recommended range shortly after that. The pc is hooked up directly to an APC Back-UPS 900 and there are no problems with that unit either as I'm constantly running self tests on it. Is there anything else I should check for? Is this a warning sign that something else might be going wrong or could it be that there was just insufficient power at start up this time? Thanks in advance.

Could be the power supply. What brand is it? Do you have a voltage monitoring program installed to check running voltages?

Your power supply is on the way out and if you're lucky it will just fail at boot up without frying anything.
Go shopping now for a good replacement that can serve as the basis for your next build/upgrade.

I don't have a power supply monitoring system. I don't even know what brand it is, the pc was custom built. I could buy an new PS today if I have to but how would I know which one will fit/work?
Thanks again. |

You need an ATX 2.0 power supply off the approved list.
The list is here : http://forum.pcmech.com/showthread.php?t=131195 Make sure the power connector on the supply you buy is 20 + 4. That means it will fit in an older twenty pin connector board with the extra 4 pin detached and can be transferred to a newer 24 pin connector board later. I don't know what's available in your local area but if it comes off the "good" list and you follow those instructions you'll be good to go. Don't get anything less than 450 watts. |

Thanks for your replies and help. I will look for a good PS today. I'm pretty sure my local Computer Builders Warehouse or Comp USA will have one of the quality power suppiles. I just hope I don't need any special tools to do this myself? Thank you. Last edited by Steady Teddy; 07-30-2006 at 10:17 AM. |

Before you go off buying a power supply, please read the label on yours and post some details. 350 watts is enough for that machine, but not if it's a lousy brand. The only tools you should need are a phillips screwdriver and maybe a pair of wire cutters to clip cable ties.
The only decent brand you are going to find at CompUSA is Antec and they are quite costly. CBW looks like they have a much better selection - Enermax, Enlight, Thermaltake are all good. |

Well Comp USA was the only store open on Sunday morning...
I purchased an Antec 500 watt SmartPower 2.0 with 20 + 4 connectors for $109. Probably more power than I need but this is the 3rd PS I will be using on this pc and I want it to be the last. The old PS was an Allied (bad). Unfortunately, I could not hook up the fan signal connector because I already have a couple of case fans running and there's no more unused 3-pin connections available on my MoBo. No big deal I guess. Thanks for all your help.

No need to hook up the fan signal wire - just a nicety. Good power supply, but a bit overpriced.
 - So, is it working now?

I know I should have looked around for other choices but I was in a hurry to get this PS swapped out.
