300 Watt Computer Power Supply

Hi,
I recently purchased an ATI Radeon X800XL and it works fine so far, but I am not sure if I have the recommended 300 watt power supply. How would I go about finding out this information? Thanks.

 

Most PSU's have this printed on the PSU itself.

 

Sorry, but what's a PSU?

 

you mean inside the PC or just on the back of it.

 

Open up your case and look at the power supply, it should be right on it.

 

i opened up the case and looked on the power supply...it is either hidden where i would have to move other parts or it is not specified. how else can i find out?

 

never mind guys, i just chatted with dell online (man their customer support is awesome) and some indian dude told me that i have a 305 wattage psu...apparently that's fine for my Dell Dimension 8300, even with the new ATI Radeon X800XL.
