Macintosh SE/30 New Power Supply (PSU), Voltage & Accelerator Tests

This 4K video shows how to replace the power supply in a Macintosh SE or SE/30 with a more powerful Seasonic. Voltage measurements shown before/after PSU replacement and after analog board is recapped and an accelerator and Ethernet card are installed.

• Seasonic PSU (Amazon US):
• Torx T15 with LONG neck (Amazon US):
• Analog Board FAN (silent): Silenx IXP-34-16 iXtrema Pro 60x25mm (Amazon US):
• Analog Board FAN (very quiet & moves more air than Silenx): Noctua NF-A6x25 PWM 12V 60x25mm (Amazon US):
• ARTMIX Stratos TwinSpark PDS Adapter for SE/30 (to add a PDS Ethernet card and a compatible PDS accelerator card in an SE/30, for example):
