Looking at the power draw while mining ethereum they are pulling 140-150w per machine which is about 900w on the PSU. Also looking at aerocool PSUs I see reports they dont put out rated power and heat up easily under load. This is why your PSU is shutting down.

Here is a list of PSU vendors graded by quality. I would replace both of those PSUs with better units.

Thank you very much. I will consider these point when I buy new Psu

aero cool is one of the cheaper brands, there good for about 1/2  there rated wattage (there designed to go upto the max for a short time) if your running higher than that then stick with bigger brands, corsair and antec are usually the best bang for buck here in the UK

you dont want a cheap PSU to fail as they often take out stuff with them if your unlucky, so its worth investing in a good PSU and also the PSU if you get a good one will last you years and years through countless upgrades

I am sorry for late answer. I bought this because of my friend. he told me why should we give a lot of money for only one PSU. its better to buy two instead of one better. what do you prefer ? which brand is better ?

this belongs in alt coins.

I prefer two 3 card rigs

you are the exact reason why.

right now  all six cards are doing nothing.

if you had a pair of 3 card rigs using

you would be better off.

6 card rigs suck for most people if they only have 1 of them.

3 card rigs make more sense.

Note if you have 3 or 5 or 6 six card rigs I am not talking about you.

Those PSUs not only can't provide enough continuous power, they are generally TRASH.
For the safety of your rig, and to solve your issue as well, please throw them away immediately and buy (a) better one(s).

Use this list: https://linustechtips.com/main/topic/631048-psu-tier-list-updated/
And buy the cheapest from Tier 1 or 2 (essentially the same) at the wattage you need.
