    Upgrading Ender3 heated bed

    I just purchased one of those 24v silicon mats for my Ender3 pro. One thing I noticed is that it's 24v 300w, while some are 24v 200w. Am I ok to run it off the power supply directly, since most of the wattage is used on initial heatup? Or do I need to purchase a separate power supply?

    Just because the power supplies are probably not the best made units, I would buy a dedicated supply for the bed.. would get one that can do at least 500W if the matt draws 300..

    Just bought a MEAN WELL RSP-500-24. I would think I could just replace the 350w with this one. The stock bed draws 200w, and I'm gaining an extra 150w while using an extra 100w.
