Good day !

I have a load of 24volts 35watts heater.
What capacity of power supply I need.

Is 24V 70w is okey? and is there any problem if I used
5000 watts power supply.

Can I Used also LED Power supply. 24V 100W.

Doesn't matter what capacity (wattage) power supply you use, as long as it provides a reasonably constant 24V DC and can deliver at least the minimum requirement of 35W per heater.

With 70W, you could notionally run two heaters in parallel - although right on the supply's rating limit. It's always good practice to have some greater capacity than what you need. Environmental effects, such as high ambient temperature combined with limited cooling airflow may require the user to de-rate the supply, for reasons of safety and reliability.
