The original power supply although quite reliable, it does generate huge amounts of heat and in some cases can warp the laser (especially on the first generation models) and also in extreme cases, can warp the console housing / shell.

Our new power supply was designed so it uses less power, runs much cooler and safer compared to mains voltage.

The new power supply is a simple DIY installation that takes 10 minutes and is compatible with ALL fat models.

It is also compatible with all the newly designed mods such as the PS1Digital, xStation, MODE, PSIO and MemCard Pro.

Please take care when replacing as the original unit runs on mains supply and may still have some power stored.

We have taken the time to write a guide as to whether buying a PicoPSU is right for you:
