4ms Row Power 35 (2022–)
The 4ms Row Power 35 (RP35) is a Eurorack power supply module. It has been available since June 2022, originally priced at $145. It provides 35W of power, which per 4ms is enough for any typical Eurorack row from 84HP up to 168HP, and more than enough for a standard 84HP or 104HP row. The panel is a compact 4HP, with two barrel plugs on the front that accept a laptop-style universal power supply.
What little documentation exists stresses clean power delivery. Each rail is separately regulated with high-grade components, and the design is efficient enough that it won't heat up your system. Modules connect via flying-bus cables or a Bus Stick, and the Row Power 35 can feed up to two distribution points. It needs the separate 4ms Power Brick 90W adapter (not included), which outputs 15-20V with center-positive polarity.
The record on the Row Power 35 is otherwise thin. No detailed per-rail current ratings (+12V / -12V / +5V), no dimensions or weight, and no noise or ripple specs have surfaced in the sources we've checked. It's a straightforward utility module from a company that's been building Eurorack gear since the late '90s.
