    Quality reliable power supply.

    High quality power supply for use with my MiSTer MultiSystem 2 Analog, not worth risking using something from Temu/Ali/eBat y etc

    Resolved booting issue with MiSTer 2

    Posted by Dave B on 25th Mar 2026

    Recommended as a power supply to resolve boot issues with the MiSTer 2 that are being caused by noisy supply voltage from other model PSUs.

    GREAT PSU

    Posted by C Tougas on 2nd Mar 2026

    I want something that is rugged and can deliver good power for a long time. This reminds me of the NES or SNES power adapters that have been going for decades. Shipped with product and came packed well. Great price. Just wish they had done this with the portable screen add-on too. ;) I know it is a risk to buy inventory, but it can be worth it for one stop shoppers. My two cents. Either way, this PSU has extra W avail for onboard expansion if you add on to your MISTER board's power draw.

    Power supply review

    Posted by Jason Richardson on 31st Dec 2025

    I’d assumed my multi system 2 would have come with a PSU but it didn’t and had to be purchased separately. Needs a kettle lead (not supplied) but not a problem as I had a couple at home. The PSU is well made and sturdy. Please with it.

    Solid purchase to use with the mister multisystem 2. If unsure, get more amps!
