Radeon 9800 Pro Crashing

[HoosPaul]

My sister just upgraded her PSU to a Corsair VX550. See here

However, when she swapped the new PSU in (making sure to plug a molex into the 9800PRO), after a few minutes she got a blue screen of death which listed "ati2dvag" as the source of the error. When she rebooted, she got a message about the card not having power. It appears to me that the molex connector on the Corsair VX550 is larger than previous molex connectors I've seen, and it has a clip which seems to also obstruct the pins from making a full connection. I told her to break off the clip, but that didn't seem to allow for additional clearance. The fan is also not on.

About 3/4 of the way down the page, you can see the Molex connector.

1) Has anyone else experienced a similiar problem with the connectors on new PSU's not fitting into older video cards? Initially, the connector seems like it might fit, but it just doesn't seem to be properly situated.

2) I told her just to pick up a male-to-female molex connector, any other ideas?

3) Anyone know if the fan runs off the molex power? I'd guess there isn't much power on the AGP Bus, so I would say yes. I'm asking this because I'm worried about her card. Which leads to question 4..

4) As soon as I realized the fan was off, I told her to power down her computer immediately. This was probably less than 10m. What are the chances her videocard suffered damage?

Thanks yall!

You are using the wrong connector. The one in the pic labeled "PCIe" is a 6/8 pin designed for newer cards. 9800s I've seen use a standard hd/cd connector.

Hard to say if you damaged the card, but my first guess is that it might be OK.

i have experienced when sometimes plugging in the molex connectors that have those over plastic bits that help unplug them ( seen in the picture before the benchmarking section) makes it hard to plug in. usually what i do is move them out of the way to plug it in.

No, I'm definately using the molex connector, not the PCI-E connector. I appreciate the comment, but I am 100 percent sure it is the correct connector. Two grounds, a +5V, and a +12V is the right plug.

The fan on a 9800 Pro should run without the molex connecter plugged in (it does on mine) but the bad news is that 9800 Pro's HS/fan is barely able to keep tempetures under control when working fine & it sounds like your sisters may have died on her. If she had the card running for any significant period of time without a functioning fan it may have suffered heat damage & the card may need to be replaced ... I'd suggest testing it in another PC if possible.

Try it again with the old PSU to see if it works. Might be a faulty PSU.

While this may seem like a PSU problem, she just replaced with the power supply linked in the original post (Corsair VX550). I would say the probability of a brand new Corsair PSU being faulty is negligible compared to the probability that a 3 year old video card failed while hooked up to the previous PSU which was outputting 0.5V AC because of bad caps. If it's not the video card, then I think it might be wise to upgrade the entire system. I certainly appreciate your comment, but it just seems like all odds point to the video card and not the new PSU on this case. I've got a 9700 Pro on the way which ought to rectify the problem..hopefully.
