Video card upgrade for hp xw8400

post #1 of 5
Thread Starter 
Hello.

I am getting the following system soon from geeks.com

http://www.geeks.com/details.asp?invtid=XW8400-XEON30-MAR-1R

HP xw8400 Workstation Dual Xeon Dual-Core 5160 3.0GHz 8GB 160GB CDRW/DVD XP Professional w/RAID

I will be upgrading the video card asap.
It comes with an 800 watt PS which I thought would be sufficient for a 460 GTX card, but after a little research I found that the PS only has one 6 pin PCI-E connector, and the 460 card has two 6 pin connectors.

The 460 gtx is specified to use a maximum of 150 watts here:
http://www.geforce.com/#/Hardware/GPUs/geforce-gtx-460/specifications

but on this page it's specified to use 160 watts:
http://www.nvidia.com/object/product-geforce-gtx-460-us.html

Does anyone know which one is correct? According to the xw8400 service manual, the maximum watts available from the PS for pci-e x16 is 75(slot)+75(6 pin) = 150. Should I err on the side of caution and stay away from the 460? What about the 460SE?

Can I use a Y splitter like this to connect the single 6 pin cable to the two 6 pin connectors on the 460?

Or will I be better off going with a 550 ti, which only requires a single 6 pin connection?

Also can anyone recommend a good and relatively quiet 460 or 550 ti video card?

Thanks

Matt

Thanks that makes sense. Now I'm looking for either a 768 MB 460 GTX or 460 GTX SE card which is 150 watts or below. I read good reviews of the Gigabyte card but they are overclocked so will use more power. Any other good cards out there which have big fans with relatively low noise? Also is it ok for me to use the 6 pin y splitter since the cable will provide the necessary 75 watts?

I have an xw8400 and it has two pcie 6 pin connectors. You might as well forget about the low noise factor. The fans on the xw8400 are loud to begin with. There is now way around this. The ram gets so hot, it needs it's own cooling fan to cool it. I have an ATI HD 5850 right now with two pcie 6 pin connectors to it.

Hi guys!

I have Ati 4850 in my xw6400 at the moment. I tried the 5870 amd 6850 to replace it, but no luck. After installing the drivers the windows 7 64 hangs up. After another reset the POST gives me some strange FSB related error.
I tired the bioses 2.36 and 2.38 and no difference. How did you make your 5850 work??

I tried one more time with NVIDIA GTX560TI. This one worked. Furmark testing showed improvement (from 12 FPS to 44 FPS), but inside some newer type of games (COD BO) no change. So I returned it.

The rest of the setup:
2x 5160, 6 GB of ram, 2x 80GB RAID0 drives.

Igor
