I don't see it and I checked on my card. That was one of the things I thought was missing because on box it refers to such a connector but on Leadtek website it does not and I physically checked for such a connection. but none to see. Its the type with two DVI outputs.
Alright, not having the PCIe power plug plunged in will defiantly cause what you describe.
Your 9800GT does get some of it's power from the motherboard (75 watts of it to be precise) but the rest comes directly from the PSU.
Look inside you case at the back side of the GPU.
You should see a port like the following.
Looking at a top view of your card, it will be the black rectangle at the top right.
Locate a spare PCIe 6 pin connector from your new PSU (the proper connector is pictured in the previous post) and plug it in.
Now it should boot just fine for you.
Yes, yes it does.
If your card does not have one and looks different from the picture above, get your money back and buy one somewhere else.
FYI, the second picture in the post above is of the Leadtech PX9800GT (you can even read it on the sticker) and it most defiantly does have a PCIe 6 pin plug.
All 9800GT's have the power connector.
There is just not enough power coming through the motherboard to run it with out one.
You are worrying me now. Mine looks different most definitely. I bought it from a newspaper and when it did not work I took it to the importers of the card, Rectron in South Africa, who tested it and said it works?
It does however look right so it must be kosher - see Leadtek website for image below
Thanks man. You gave me a fright when yours was totally different looking. I have bought a different MotherBoard - Asus becuase they say Foxconn not so great and will see if that works over the weekend. I feel frustrated because PSU is fine theoretically and everything works with it. only when 9800GT card goes in. My BIOS is updated regularly via Foxconn's update program.
Underclocking means I won't get good performance and won't be able to overclock in any meaningful way, not that it is an issue. But still feels like a ripoff.
Window XP, Vista A PCI Express or PCI Express 2.0 compliant motherboard with 1 full-height free slot
Installation software requires DVD-ROM drive
VGA(VGA converter needed) or DVI compatible monitor
A Minimum 400W or greater system power supply (with 12V current rating of 26A)
Unfortunately for you, your VIA P4890 based motherboard is stuck with PCIe 1.x.
The update to PCIe 2.0 did more than just double the available bandwidth.
It also doubled the 75w supply from the PCIe slot to 150w. That (and not the underclocking) is why it can run with out an external power connector.
Also, seeing as the the 9800GT has a TDP of 105w, you should have no issues bringing your card back to the 600/900Mhz stock speeds.
Make sure and post the motherboard you have chosen before you buy it.
If you have a choice of a few different boards, post them and we will help you locate the best option.
You will need an Intel x38 or Intel 4 series based motherboard to run your GPU.
