I got a damaged ATX PSU with primary transistors (13007) blown. When opened to repair I found that it doesn’t have EMI filter (markings present on pcb). I decided to include one and designed as attached pic.

As not an expert I’m not sure about the required values of X caps and inductors. The PSU is rated as 500W. AC input is 230v rms, 50/60 Hz.

Please suggest me the values of EMI filter components (and/ or how to calculate)
