Excuse my English, iam not a native speaker
So iam planning on upgrading my graphics card (i have Palit 4870 512mb atm) to something like 6850 or 6870 and iam worried that my Power Supply wont be able to handle it (i have this one for 470w ). Iam kind of low on budget so id prefer not to get a new PS if this one can handle new graphic card. Tried using power supply calculators but not sure if you can trust them.
Ill try to list all my other specs to give general idea about power consumption, i dont know that much stuff about hardware anyway:
Proc: i5 2400
MB: Gigabyte P67A-D3-B3
RAM: 2 panels of DDR3 - 4gb total
HD: Western Digital 500gb Caviar Green
Some DVD-RW
Also, not sure if it matters but i occasionally use gamepad and i have only one small fan on the back of my PC (if not counting two fans on 4870 and CPU fan).
So in short question is: will 470w PS be enough for replacing 4870 with 6850/6870 if nothing else is changed?
