So I'm planning to replace the GPU on a 10 year old HP m8330f, it currently has a GeForce 8500 GT. My question is will the EVGA GeForce 8400 GS work on the PC even though the PSU wattage (300w) is less than the Reccomended Ammount of 350w? I don't plan on doing any gaming on it (other than Windows chess) Just Web browsing.
