I want to upgrade my oldie pc with a new cpu and gpu.
At the moment im running 8600 GT and would like to place a 9800 GT in its place
I was wondering will my powersupply be enough for the new gpu?

This is my power supply:
The minimum is 26A for the gpu. But i dont know how do i count that up?

Thanks for your input!

What is exactly the model of 9800GT? Is it the one without 6pin power connector?
Looking at the specs, it has 20A on 12V(1) and 18A on 12V(2) rails, so it's good PSU if that specs are true.
But again, IF the specs are true then you can use a single 9800GT (with OR without 6pin power connector) on that PSU. :)

According to the specs, you are going to get anywhere from 15 to 33 amps on the 12V rails, depending on how much 3.3 & 5 volt you use. Questionable at best.

Nvidia recommends a minimum 450 Watt PSU. The card can pull 140 watts itself.

I would seriously consider getting a new PSU.

Ah, I guess that 9800GT need 1x 6pin power connector from PSU.
How old your PSU?
The specs of PSU are good, but it only has 430W max. So, I think you will better with a brand new PSU, it also good for longer term. Get a trusted brand like Corsair, Antec, Seasonic, OCZ, SilverStone with 500W minimum for a single graphic card.
But if you are really just want to buy that 9800GT then 450W is enough for your need. :)
