Hello,
I installed a new invida GeForce 7600 DDR3 Graphics Video Card 256MB PCI Express on my m8400f Desktop PC. I have been using my motherboard video since my last video card failed a year ago. After installing the new card the computer instantly shuts down when turning on. I have a 300 watt power supply with 25 amps on 12 volts. I don't know of the new card may be bad or the power supply is shutting down due to over current or over voltage. The last card was a similar card which came with the computer. It was an invidia geforce 256 mb pci express which when it failed it did not shut down the power supply but had lines in display. I don't have another computer to test the card in. The place I bought it from is going to replace it with another new one to try. The computer is about 3 1/2 years old which I bout brand new.

You will need to get a new psu. That card requires a 350W psu minimum.

Thanks, I kind of thought that might be the case. The pci express slot on my motherboard had my old GeForce 8500GT which was 256m and came with the computer brand new. Apparently the old card did not demand as much power and current rating. I was getting ready to buy a power supply. When I checked the info on my power supply it was 300 watts total with 25 amp rating but the 12v and the 5v combined should only be about 275 watts. My computer also has two hard drives. I wonder if the power supply contributed to the failure of my previous card. I did not check the voltage coming out. It may be on the low side or as some has set that some of the caps may be failing. I do keep the machine blown out regularly so it does not overheat. It also has the sata hard drives. I have plenty of hard drive space and am running vista premium. I was looking at this shark power supply on ebay and wonder what you think. Product Specifications

To be totally honest, I don't think much of it. The psu is one of those components that you should never cheap out on. I would suggest brands like seasonic or corsair. Look for a psu that is at least bronze certified, something like this perhaps >> http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Hope this helps, good luck.

I installed a new power supply with 650 watts and 30 amps at 12 volts. I then tried the new card and it immediately shut down within a split second when turning it on. Same senareo as the last with the origional psu. The previous card that failed over a year ago just caused a wavy screen but never shut down the psu. I sent back the new card and will be receiving a replacement in a few days. If that one does the same thing I will probably get a regular pci graphigs card and not use the express slot. I only have one pci express slot 16 and two express slot 1. I have regular pci slot that I opened up by removing the phone modem which I will never use. If it is a motherboard issue it is not worth it to me to replace it since the computer 1s about 4 years old anyway. It is a very good running machine that I blow out the dust every three or four months. The graphics on the mother beard isnt all bad. Just wanted to get it back to the way it was when it was new. I all I can think of is that the new card had an internal short. I will find out when the new on comes. I just wish I had another machine to test the card on.
