is this enough??

[schumi_thelegend]

I just bought an XFX 7900GS overclocked with a core clock of 600 MHz. i already have this power supply

my question is will this power supply be enough because i have already exceeded my budget for the system and cannot buy another PSU
(btw the graphic card requires external power supply. i dont know whether my PSU has a PCIe connector or not)

You might be pushing it a little but I think you will be fine. What are your other components?

 

[schumi_thelegend]

Core 2 Duo E6300 (no overclocking here)
Intel G965 board
4 sticks RAM @533 MHz
DVD Rom and DVD RW
1x 120mm chassis fan
2x LEDs

i just read the PSU specs . and it says no PCI-E connector. is this a problem.

my friend also has 1 spare ASUS 400W PSU. Are they good? it has dual 12V rails with a total of 24A on 12V.

If you can get that ASUS PSU for free then that should work according to your specs. Most of the time though, you cannot just add the 12v1 and the 12v2 rail together to get the total amp rating. Did you do this? What is the model number/name of the ASUS PSU so we can check it out.

yes i did add the 2 rails together. and it is not a 400W but a 350W PSU. i dont know the model number but i checked the specs at the asus website.

and why does every1 wqant to go for a 600W PSU. we r facing an energy crisis but companies like nvidia and ati are producing evermore power hungry cards

but what abt the external power for the graphic card. does it require a special coneector(the PCI E connector) or is it fairly common.
