I am trying to buy a GeForce 8800 GT 512MB Graphics card But First I was trying to find out will my PC run this card?

My PC Specs:
My PC Model:HP Pavilion A6242N or HP Pavilion A6000
Processor: AMD Athlon 64 X2 Dual Core 4800+(socket AM2 940, 1.344v)
Memory: 2 Sticks PC2-5300 1GB and 2 sticks PC2-5300 512MB = 3GB DDR2

Power Supply:
Name: HP-D2537F3R
AC Input(47-63hz) 100-127v/64A / 200-240/4A

DC OutPut +5/25A , +12v/14A / +3.3v/18A , -12v/0.8A
+5v and 3.3v SHALL NOT EXCEED 165W
+5v and +12v SHALL NOT EXCEED 218W
Max Output Power 250W

Graphics Card im buying:
Geforce 8800 GT 512 MB
Maximum Graphics card power (W) 105W

My old card(8400 GS 256 MB):
Maximum graphics card power (W) 25W - I can run it no problems

If you need more informations let me know, and also tell me how to get them

What happens if I try it out? will it ruin anything? will it damage the card? will it lower the cards life? will it ruin my PSU?

Your PSU only has 168W on your 12V rail, the 8800GT has a TDP of 105W, leaving your CPU and everything else that needs 12V power less than 65W to work with, thats no good, it will probably stress your PSU out and kill it, or it might not boot at all.

Worst case scenario, the PSU goes out with a bang and kills all of the other components in the system with it. Most likely scenario, it slowly stresses, goes out of spec, and shuts of your system at random times and will eventually refuse to boot.

I would NOT try that. Not enough power to be safe. It may just not run, if its really not enough, but it might run, being on the edge of enough power. If you run it on the edge, you are risking it blowing out, which could do nothing, but could also damage other parts of your PC. Definitely not worth the risk IMO. I'd get a bigger PSU and be safe.

Ohhh. Thanks for the fast reply and help guys really appreciated.

But I got more questions
How many Watts is available if I remove my Old Graphics card?
Any video cards recommended that will match my PSU availability?

Also I found a thread that have same problem with me same PC and same Power supply
He said he tried out GeForce 8600 GT and it run well no problems in 2 years

It does not matter how many watts you will have available if you remove the old one. You will still not have enough for an upgraded system to run reliably.

What do you want to do with your system? Any modern graphics card will require at least a generic 350W as a minimum to be able to run your system without problems.

The 8600GT does not require a dedicated power cable. The 8800GT that you are looking at does. And as a matter of fact, most modern graphics cards dedicated for gaming will probably require that cable too.

If you want to do some gaming, don't think about it, unfortunately you will NEED to upgrade your PSU.

Think of your PSU as the wheels of a car. It does not matter what sort of car you have up there, even a Ferrari on wooden wheels will not be able to speed more than 20km/h and it will not do so until it soon breaks down! Better to invest in a good quality PSU and have piece of mind.

+1 to darkguset. You really need a new PSU to upgrade your GPU. Its worth the money in the end anyway as a good power supply that you get now is the type of thing you can transfer to your next rig as well. Doesn't have to be super expensive or huge either, but a good quality 400-500W + PSU (can be had for ~$50 +/-) will run most graphics cards out there right now, outside of the dual GPU type cards. Its a worthwhile investment.
