3D Printing Power Supply LRS-350-24 Meanwell 24V/14.6A 350W for Sovol Ender-3 Pro/Ender-5 Review (2026)

Who this power supply fits

This listing packages the Meanwell LRS-350-24 power module for 3D printer owners who need a replacement or upgrade supply for machines like the Sovol, Ender-3 Pro or Ender-5, all of which commonly ship with a similar rated 24V brick from the factory. It suits anyone whose stock power supply has started failing, running hot, or making noise, as well as owners adding accessories like extra lighting, upgraded hotends or enclosure fans that draw more current than the original supply was sized for. Because it uses the same 24V output most Creality and Sovol style printers expect, it is meant as a drop-in electrical replacement rather than requiring rewiring of the printer's control board.

Specs and design explained

The core module is Meanwell's LRS-350-24, an enclosed switching supply rated for 350 watts at 24V DC and 14.6A output, with an input range that accepts both 115V and 230V AC mains, selectable by an onboard switch. Meanwell's own datasheet lists an efficiency around 88 percent, an operating temperature range from negative 25 to positive 70 degrees Celsius, and built-in protections against short circuit, overload, overvoltage and overtemperature conditions. The supply also carries a 150 percent peak load capability for up to one second, useful for handling the current spike when a heated bed first switches on. Meanwell's enclosed case measures roughly 215 by 115 by 30mm and includes a built-in cooling fan.

Living with the power supply

Installing a replacement supply is mostly a matter of matching the mounting holes to the printer's existing bracket and transferring the wiring from the old unit, following the printer's color coding for live, neutral and output terminals. Because this listing is a reseller package built around the same Meanwell module used across many printer brands, the case shape or hole spacing may not exactly match the original bracket on every model, so it is worth measuring before assuming a bolt-in fit. Once installed, the extra headroom above the stock 350W rating gives some margin for accessories like LED lighting or enclosure fans without pushing the supply to its limit during long print sessions.

Trade-offs and how it compares

Compared with buying directly from a distributor like Digi-Key or Mouser, this Amazon reseller listing is more convenient for a one-off printer repair but may not include the full manufacturer documentation or packaging that a direct industrial order would. Against other repackaged LRS-350-24 listings sold specifically for 3D printers, this one is priced and rated similarly, since they all use the same underlying Meanwell design. Buyers who want the absolute lowest noise option should note the fan is always active rather than temperature controlled on the base LRS-350-24, so a fanless or semi-fanless supply is worth considering for a completely silent printer build.

Verdict and who should pick something else

This power supply is a solid, well documented choice for Sovol, Ender-3 Pro and Ender-5 owners needing a reliable 24V replacement or upgrade, backed by a widely used Meanwell design with real protection circuitry built in. The extra headroom over stock ratings makes it a sensible pick for anyone adding accessories to their printer. Buyers should confirm the case dimensions match their existing mounting bracket before ordering, since case shape can vary slightly between resellers of the same core module. Anyone building a fully silent printer enclosure may prefer a supply with a temperature controlled or passive cooling fan instead of this always-on fan design.
