It delivers clean 5 V DC (up to 4 A) and true 9 V AC (1.5 A) from a heavy-duty linear transformer, plus extra 5 V/12 V for FDD. Features an Adjust & Protect module for precise 5 V tuning and full surge protection. Every unit is triple-tested on original hardware for maximum safety and longevity. Trusted by the global retro community and praised on eBay as “the best C64 power supply”. Protect your Commodore from the legendary “brick of death”.

Stay original! Choose the genuine Electroware C64 PSU and beware of fancy, cut-down clones flooding eBay & web.
The original Commodore 64 PSU is the #1 cause of C64 failures. The separate 1541-II PSU can age and fail as well. Our solution combines both in one safe, modern unit: the C64 PSU “2-in-1” powers your C64/VIC-20 and the 1541-II/1581 drive simultaneously.
It delivers clean, filtered 5 V DC (up to 4.0 A) from an industrial-grade AC/DC module and true 9 V AC (up to 1.5 A) from a heavy-duty linear transformer. For the floppy drive it also provides 1 A @ 5 V DC and 0.5 A @ 12 V DC. All packed in a compact, durable enclosure with proper ventilation, mechanical protection and electrical isolation — a drop-in, community-trusted Commodore 64 power supply replacement.

For years we’ve listened to the community and iterated relentlessly. This is our 12th revision — designed by active C64 users, refined with real feedback, and widely accepted as the industry standard replacement PSU.
Sadly, our concept has been copied, often with reduced features and weaker protection. Fancy enclosures and loud slogans don’t equal safety. Choose the original Electroware design — we stand behind its quality, protection circuitry and real-world performance.
Our Adjust & Protect hardware enables safe fine-tuning of the 5 V output in a limited range (typically ~4.9–5.3 V DC with a C64C reference load). This lets you compensate cable/switch drops and match modern expansions. With a 4 A budget it can also power a C128 via a C64→C128 adapter — basic voltage adjustment helps when switching between C64 and higher-draw C128 setups.
Need even more precision and the lowest ripple? See the C64 PRO PSU.
Choosing the adjustable version? Calibrate with ease using our C64/C128/VIC-II Voltmeter.

Warning!
Risk of electric shock and energy hazard when opened. Service only by qualified technicians. Protect ventilation holes from foreign objects and liquids. Do not install near heat sources or in high ambient temperatures. Indoor use only; do not use outdoors, in dust or high humidity. Output current and power must not exceed rated values.
This replacement PSU is intended only for Commodore 64 & VIC-20 systems (and 1541-II/1581 drives) and should be considered an integral part of the computer system. Do not connect to other devices. The manufacturer is not responsible for effects of unauthorized repairs, modifications or misuse. A quality replacement PSU reduces failure risk but cannot guarantee full functionality of a 30-40-year-old system.
