GET READY FOR PRO. GET CONTROL. GAIN FLEXIBILITY. EXPLORE NEW FEATURES.
Commodore C64/C128 PRO PSU is a real, new original design. Supports C64/C128 and 1541-II/1581 FDD units. It's keeping the same redundant protections as our regular PSU line but enabling many advantages and unique features not available in any other PSU. New intelligent architecture is actively distributing power wherever it's needed most (5VDC/12VDC line) and reduces the power losses (heat). The total output power has risen to 31.6W, output ripple is significantly lower for both 5 and 12VDC rails, no-load AC output voltage has been reduced to same values as original C64/C128 PSU were providing (according to your feedback).... but what's most important: now you are able to adjust the output 5VDC voltage in safe range of 5.0-5.5V to set the exact 5.0VDC for your system as every unit is unique and draws different currents.
It is all integrated into well known, small enclosure with dimensions similar to the original Commodore C64 PSU (and much smaller than C128 PSU). Durable, professionally molded enclosure assures good air ventilation, mechanical protection and electrical isolation. It holds the trimming potentiometer in discrete and secure location.
THE SCOPE OF THE CLONE HUNTING GAME
For many years we are listening to your feedback and offering the unique, new replacement PSU for Commodore computers. Thanks to continuous contact with Commodore users community worldwide our PSU is getting better with every feedback we receive. PRO is 11th revision offered now, always designed with retro computing love and by active C64 & C128 users.
Commodore C64 C128 PSU PRO unit has been created according your precious feedback and with your continuous assistance. Inspired by the Amiga PRO/Duo/Duo+ units it's enabling the features you need and the specifications we discussed many times on our FB page.
We are proud to say that our original PSU design becomes an industry standard, accepted and valued worldwide. What a pity some of them were copied and crippled by many other sellers hungry for "easy" profit. Offering PSU packed in fancy enclosures & stuffed with tons of ridiculous marketing slogans like "designed from scratch". Please beware of these copies as we can't take responsibility for their quality, safety features and overall performance.

C128: Due the high current draw on C128 systems it's recommended to order the C128 ouptput cable version accordingly, especially if your PSU will be powering the C128 and 1541-II / 1581 FDD at the same time. C64-toC128 adapter can be used but notice the larger voltage drop on the cables (maximum voltage adjustment may not reach 5VDC on heavy loaded systems using FDD at the same time).
1541-II & 1581 FDD: Mind that the voltage drop would be different on the cables for C64 / C128 computer and on the cable leading to FDD units when used at the same time. This means that the FDD unit will get a slightly higher 5VDC voltage than delivered to your C64 / C128 unit. It's ~0.2V of difference in most cases. As the voltage drop difference is most visible on the C128 systems (high current draw) it's recommended to set the 5VDC voltage as low as possible to keep stable computer operations (measured on C64/C128 main board) even if it's less than 5VDC (most C64/C128 systems will work stable with 4.8VDC). This way your FDD will not exceed the 5VDC much. The voltage adjustments range is always in the safe limits but it's better to balance the C128/C64 and FDD looking for some common denominator (for example 4.9V for computer giving 5.1V for FDD).
Adjustment: potentiometer is on safe, low-voltage side of the PSU and screwdriver hole is guided preventing internal shortcuts, but for your and your equipment protection please always use isolated screwdriver for adjustment process (100% plastic is the best one). Notice rubber cap on the adjustment hole - it should cover the hole during regular usage to protect from dust, objects or liquids dropping in.
