Power supply issue

[baysiderocks321]

Does anyone no the W PSU of a compaq presario sr1620nx? i installed a geforce 8400 and World of Warcraft runs so terrible i dont understand im thinking maybe it is the power supply but i am not sure it says require 300 min +

it doesnt matter on the wattage, check the 12 volt rail it must meet the graphics card power, my compaw had a 250 watt inside the 12v was 14 amps and my geforce 9800gt needs 18 so I bought a antec basiq 500 for 40 at newegg, great power supply, but mine ran like crap to until I switch to my antec power supply.

Did you ever get that geforce 8400 to work on your sr1620nx? I am trying the same thing now and my computer is really really slow.

8400GS was not meant for gaming.

8400gs is just to weak for any meaningful gaming considering how demanding games were half a decade ago. Instead of buying a card that only costs as much as a frozen pizza you need at least a 5670/gt240 to be able to see playable fps in wow.
