CETUS3D VS PRUSA UPGRADE

In a short circuit event, more power could be dumped into the component or device that is short circuited – but that would happen with any PSU, just with a low power one it won’t dump as much before the PSU’s short circuit protection kicks in. So, a PSU that has much more power than it needs won’t really do anything bad. If you take a 600W PSU and plug it straight into a 40W heater cartridge, only 40W will be used. It’s the component that “pulls” in the current it needs – the PSU can only limit it. Is it dangerous to use a higher rated power supply with lower rated components?Ī PSU gives components the ability to draw the current they need (up to a limit).

Plus, it’s always good to have some extra power if you want to upgrade your 3D printer with other rated components later. current spikes when motors and heaters turn on). When choosing a PSU, it’s a good idea to budget at least 10% more power than you need – this will account for voltage drops, increases in resistance due to higher ambient temperatures, and handling any transients (i.e. This means you need thicker wires to handle the larger currents, so more copper needs to be mined to manufacture it – meaning a larger environmental impact. Using a 12V supply means you need to double the current than that of a 24V supply for the same device you are powering.

If you’re choosing a new power supply, it’s wise to go with 24V, but either standard will work fine as long as you use components with a corresponding rating.
