PowerUP! 64W v1.2 – Commodore 64 PSU replacement/upgrade board (rebuild kit)
A new version is available here
TL;DR: Don't just save your C64. Also save your PSU! Rebuild your original C64 PSU (power supply unit) with modern and reliable technology instead of buying a "saver" or new PSU.

Availability: 0 board(s)
The stock C64 PSU is infamous for damaging/destroying your computer when the PSU fails. The PSU consists of mainly two parts;
1) the iron core transformer which outputs 9V AC
2) the linear regulator board which transforms 9V AC to 5V DC
The second part is the weak link and can cause a too high output voltage. The original construction is ineffective, unreliable and produces quite a lot of heat (nice for warming you feet though). Keep the good part and replace the bad one!
These assembled and tested boards are a modern replacement/upgrade with switched and filtered voltage regulation (9V AC to 5V DC) instead of linear regulation. The need for a so called "saver" is minimized/eliminated and you can keep on using your original Commodore PSU. The board fits the beige wedge shaped PSU variant; Part No. 902503-06, Part No. 902503-11 and eventually more. Works with 110/230V and 50/60 Hz transformers.
Output voltage: 4.95-5.05V* (@1A)
Output current: 2A MAX
Efficiency: ~90% (original board: <50%)
Size: 50x70x22mm (WxDxH)
Built with high quality parts from Nichicon, Aimtec, Samsung and more
Overcurrent protection
Overheating protection
Short circuit protection
1x 220 ohm resistor included for power LED option
*There is a ~0.05V voltage drop at 1A current draw across the output filter. The filter can be bypassed by closing the solder bridge.
Changelog:
v1.2:
* 2x 3300uF smoothing capacitors (v1.0: single 4700uF)
* Filter/choke coil with only 0.05v voltage drop@1A (v1.0: 0.1v@1A)
* Power LED option – place for resistor and cables/header on board (v1.0: N/A)
* Filter bypass solder bridge (v1.0 N/A)
The installation requires:
1) Opening the PSU (more or less force is needed as parts are glued together)
2) Removing the original PCB and installing the the new PCB (soldering)
ALWAYS measure and verify correct output voltage and polarity BEFORE connecting the upgraded PSU to your C64.
Price:
€28 each including UNTRACKED international shipping
€35 each including TRACKED international shipping
Payment as gift to PayPal
The PSU boards are also sold elsewhere.
Thanks for looking!
