Blinking mode with lots of leds and high current

Other Hardware LEDs and Multiplexing

Hello everyone !

I'm dealing with my LED (WS2812B 5volts) project which consists in putting at least 300 of them in my room.
In the worst case scenario, where they are all at max brightness, they draw a current of 0.06 * 300 = 18A.

I'm planning to use a HAILI power supply which can handle 5V 20A.

In my program, I would like a stroboscopic mode where all the leds flash at the same time from 15Hz to 100+Hz, something like that.

I was wondering if this could be a problem for the power supply to handle this type of current change. Because it supplies continous current,

What are your opinions about this problem ?
Thank you !

Power supply might be humming at 18A, you may find the on/off hum annoying.
Depends on how good of a supply it is. Never heard of HAILI brand (?).
Flashing like that, not my cup of tea. Anything above around 20 to 25 Hz will likely just seem on, but at varying brightness levels.

That's what capacitors are for. If the supply is properly designed it will be fine. If not....
