9550 though? I can't really find any info...I know the higher end 9700/9800 used them.
Excuse me,That returned about zero amount of info except that it's a Powercolor branded card...nothing about why there is a molex connector when it seems 99% of 9550 don't have them. Even the photos are wrong (when I do as you said) and don't have the molex connector. I really just wanted to know why it's there in the first place.
thought you would get a link to gpureview.com, but the review of your "special" 9550 DDR2 seems to be offline.
Info to your Powercolor 9550 version:
Let me call it "top of line" Radeon 9550 with Hynix DDR2 memory chips. RV350 Gpu (maybe RV360). At least 398 MHz Core / 300 MHz memory.
Exact specs may differ, there are at least two versions with the same UPC EAN number. I know a dark brown PCB version with molex too.
Has a level near a 9600 pro or 9550XT.
Few info of DDR2 Radeon 9550s at vgamuseum.info. But no Powercolor version. Missing at TPU gpu DB.
The power connectors for Radeons 9550 to 9800:
With the 9000er Ati series the AGP port comes to power limits, especially when OCing. See also post 10085 from lexluthermiester.
The 9700 have FDD (floppy) power connectors in general, the 9800 changed in general to molex (HDD) power connectors. Usuall top right corner.
The 9500 may have a FDD power connector top middle of the card.
The 9600 (and 9550 as "downclocked" 9600) usually have no extra power connector, but many of the 9600 pcb custom layouts have the option. There was a "9600 pro FDD power mod" for hardcore overclockers to solder in a power connector for better OCing results.
Molex power connectors did work well, the FDD power connectors tend to get hot or burn when overclocking. Made bad experience with FDD power connectors on 9800 SE AiW when (soft)modded to full 9800s.
Back to the Powercolor 9550 DDR2 means, your card has two special points. DDR2 and Molex instead of FDD power connector. And even the option for power connectors is very rare at 9550s.
My personal thought is, that Powercolor made a very fast "so called" 9550 with a new PCB layout for DDR2 memory and factory OC. Called 9550 instead of 9600 to sell it on budget prices. And changed to molex like 9700 to 9800 series.
