My psu has two wattage numbers on it's sticker:

+5v and 3.3v
shall not exceed 160w
+5v and 3.3v
Max Output Power 300w

so is it 300w or 160?

also, could it power a radeon 6770? http://www.newegg.com/Product/Product.aspx?Item=N82E168...

You need to know the power on the 12V rail but most likely no

You have 216W on the 12V rail (12V x 18a = 216W) the 5770/6770 can draw over 100W under load so unless the rest of your system is ultra low power then you would need a new PSU. The 6670 is much lower power so it may be OK on that PSU as long as it can supply the power the label says it can.

I would not go beyond the Radeon HD 6670 unless you are willing to replace the power supply.
