Hi guys , recently I bought a 9800 gt which was actually a second - hand . I bought it for $ 61 from ebay . But when I received the item ,it didn't have a 4pin molex to 6 pin power connector . So I bought a 4 pin molex to 6 pin power connector from ebay . ( http://www.ebay.com/itm/260891292556?ssPageName=STRK:ME... ) But the 4 pin to 6 pin power connector that I bought had only one 4 pin molex to a single 6 pin power connector instead of two 4pin molex to a single 6 pin connector . The problem is that when I connect the 4 pin molex to 6 pin power connector to the graphics card , only the fan of 9800gt works and I am not getting a display on my screen .

Here is my system specs :-
PSU :- 500W
Motherboard :- Asus p5gc-mx/1333
Processor :- Intel core 2 duo E7500 @ 2.93 Ghz
RAM :- 3 GB

Please help me . I don't know what the problem is but I desperately need to run the graphics for playing latest games .
Please tell me whether I can run this graphics card on my PC .
Please help me !

It should work regardless, it would not starve off power until you load it!

There is always a possibility that you got a dud card but what did you have before and did you uninstall it properly, is your default graphics PCIe in bios and so on?


I had a 8400 gs early . I uninstalled it properly . Yeah this is my bios setting :- PCIe Express / Internal VGA
I tried PCie express option alone but it didn't work . I sit because of the power connector ?

Looks more like a bad card! 9800GT only uses max 124 watts and it should work with your current adapter. Can you try it in another computer?

But like I said , the real new 9800 gt from Nvidia has two 4 pin molex to 6 pin connector . But I have only one 4pin molex to a single 6 pin connector .

I know that the card gets 75watts through the slot and it gets supplemental power from your PSU but it does not exceed the 75watts on startup all it cares about if there is voltage coming through the 6pin regardless if you have 2 molex or 1! The question is though since your PSU does not have PCIe power connection whether it can handle the card. Make and model of PSU?

My PSU is brand is priya which is basically an Indian manufactured one and I bought if for 25 $ and it supplies 16 amps power in 12 V rail

16amps on the 12 volt rail is to little the card needs a PSU with 24-26amps total on the +12volts!

If your PSU has only a single 16A 12V rail, then you have 192W available to use. 124W seems a bit high for 9800GT, I think its closer to 110W. Either way once you subtract the power the GPU will use, you have less then 100W for your CPU, motherboard, and drives. Basically, your PSU is much to small.

A single 16A 12V rail is very unlikely for a 500W PSU. At this point I would say you need a new PSU. I would also find a friend and test the card before any return, assuming it was possible in the first place, becomes impossible.
