i decided to go with the 75A only because its very compact

i decided to go with the 75A only because its very compact
ive never run any draw tests with my 30A PS on my 12" but i have dual extruders
and I have had both extruders plus the bed heating up at the same time, without any issues
and they heat up quickly
It's very very quiet I can barely hear it at least the one I got. The fan doesn't ramp up unless the sensor detect a higher temperature that the operating default. 30 amps it's nothing for these ps. I Highly recommended.
How hot does your power supply get? My fan isn't turning on and the printer gets pretty warm to the touch.
The ps fan is supposed to be always on. Mine always stay at low revs. I have only seen the fan speed up when I'm using it for changing my lipo batteries specially if I'm using 50 or 60 amps. But in regular use it always stay warm but no hot to the touch.
If you fan is not turning on at all you probably have a defective unit.
A bit late but my experience with my cheap 30A power supply off amazon has been surprisingly good. I have the 12" heatbed and hex hotend and both heat up fast.
same here,no issues
And let's not forget... In Marlin's Configuration.h file where you setup your printer... One of the #define's is ATX_POWER or something link that... ATX Power Supplies work for this kind of stuff.
