Thing is the computer doesn't power up at all if I connect the required connector. If I remove it it just doesn't post and no beeps are coming from the speaker.

The seller told me he doesn't need me to return it and he'll give me a refund on it so that's why I'm trying to find a way to fix the problem. Any suggestions?

Oopsss!

Check them out now.
Thought that embedding the thumbnails would allow you to see the bigger ones.

Sure mate. I took 3 pictures of the whole card, but they're a bit low res, excuse me for that they were taken with my cellphone.

Hello to everybody, I would to introduce myself. My name is Nick and I'm a big fan of 3Dfx. So I finally got a Voodoo 5500 AGP for my Retro PC. The motherboard is a Slot 1 one with support for AGP 2x so it's definitely ok for the card.
Now the problem is that the card won't work. Simply put, if I connect the needed power cable, it refuses to power up at all. I see some slight movement in the fans of both the card and the cpu, but it just stops. If I remove the cable though it powers up but of course it doesn't post.

I tried 3 more motherboards and a couple of extra PSU's and it still produces the same problem. I tried disconnecting every other extra device and it still stays like that. I emailed the seller and he told me it worked fine last time he checked, and that nevertheless he would give me a refund. Thing is, on the back of the card and on the far right, where the vga out is located, "DEFECT!" is written with a green marker. This makes things even weirder!

What do you think is going on?
Got any suggestions of what might be wrong?
