Sorry I forgot my spec.
My tower is an Aopen HX 08. The case (which I still have!) says something like 200w-230w but I went to check on the net and I found a very good review about it but the spec. says 300w. In the review picture it looks like exactly the same as my tower but I have to be 100% sure cose I want to get a new graphic card (one of the latest ones) and they require 300w at least...
Any info., please? Also, is it possible to change the power supply without changing the whole tower?
