PSOne LCD on PC PSU

[Daninino]

Hey Everybody

Just orderd The Sony PSOne Screen I am going to use in my project, and it only costed me 80$ which i really cheap, because in Denmark it cost around 320$ from new 😱

But my question is:

Is it possible to run the PSOne of an PC PSU.
PSU gives 12V and the screen only need 7,5V. Since I am going to use cabinets fans so instead of using 2 PSU´s I could use only one.

Found this in a Thread but I don't know much about it so I need it explained REALLY SIMPLE 🙄

hey lowjacker,

just in case you have normal pc- psu's.

hang a LM317 behind 12 V output of a computer- or other -psu and a 1kOhm resistor on the middle-pin . You'll get then 7.5 Volts to run the psone lcd.

Check out the datasheet for the LM 317

Just put the 1k resistor where r1 is the diagram (middle pin is V-out)
