What power supply is best for Whatminer M3?

I just grabbed one today. What’s a solid power supply to pair with it? Thanks!

For a start, how power is it rated to pull? Do be aware that if it uses more than around 1,100 watts you will need 208-240VAC to power it. That said, probably any of the Bitmain APW supplies would be fine. Just be sure to get one rated for more power than the miner will pull. edit: Miner needs 2,200w PSU so Bitmain APW series will not work.

Mine hasa whatspower P5 installed .  But when i plug it in to the wall it does not turn on.

That is a 2,200w PSU which requires 208-240VAC power. Is that what you are feeding it? It will NOT work if fed 120v.

I tried ot plug it into the wall and it did not turn on. I can not find a power supply for it. Which one should i buy?

Again, what voltage is the wall socket? 120vac? 208-240vac? The voltage MUST be over 208vac or the PSU will not start. Even telling us your country would give a clue as to what your common voltage is... As for replacement PSU's you need to check with the manufacturer because for the past few years most miners are using custom built-to-spec PSU's that deliver non-standard voltages (not just 12v) to power the miners.

I am in the United States and I have a standard 15 amp outlet

Then that is your problem. Normal power in the US is 115-120VAC and as has been repeatedly said the miner requires 208-240v. Find an unused dryer or stove outlet (which are all 220-230V in the US), get the correct cord and I bet it works.... Not being snarky but -- if you do not even know that normal power in the US is 120VAC then things do not bode well for you with this venture...

Hope I am still at the subject! I know someone who use an inverter with 2 truck batteries connected in series. He has 2 servers running 24/7. I dont know more details yet and hope to get some answers about it. Next week I'll check that out to see how it works.

Hello, From where did you buy it?? Expensive? Cand you provide more details?

´ i have a few m3 and what i know is that they dont turn on if you are not using whatsminer own psu provided whit the miner. the miners psu has a cable connected to the controller wich allows it to controlll fan rpm and something more. you will need to get a m3 psu for it to work , they only work for about 5mins and shutdown whit random psus.
