Some information and pictures on the ZSSR5391A power supply from the PlayStation 3. This was the first version of the power supply used in the launch models (CECHA01, CECHB01). I highly recommend you avoid using these at all costs as they are prone to overheating, which can cause YLOD and other related issues. If you are planning to make a PS3 portable, go with a more efficient model that uses less electricity.
*Note: Once I renew my web hosting, I'll get these images on my server.
*Note2: I'll be posting pictures of other parts as I get the time to do so.
