Noooooooooooooooooo!!!
Never use those power supplies for anything, ever, except powering LED lights maybe.
That is a non regulated transformer power supply with no output control at all, so voltage varies wildly with load, and is way above 5V at low loads when set to 5V.
Or look at it the other way, never use a 3$ power supply to power 1000$ equipment.
Get a MeanWell or Delta 5V power supply, at 20-30$ they are still cheap and can be found easily online.
In the meantime, if you have an old Samsung 5V charger, they were really good, the original ones, not the counterfeit ones.

what error are you getting? need more information from your install also, without it we have no way to know what the issue could be.

I would say that power supply is marginal

I would get a DIN mounted PS say a MDR20-5

Older encoders may draw considerable current

Hi, 
i have some problems to convert my *ini and *hal file from QT-Dragon to Probe basic. Have some errors when i start it. I screenshot my CNC Folder. 

i cant find the error. please help me that i can start it
 

well, I'm trying to locate the trouble, it's with the encoders: when I unplug them, there doesn't seem to be any restarting, and when I plug them back in, the default comes back from time to time.

my encoder is power by 5V

Could it be the power supply or the encoder ground?

below, is the power supply for the 7i97t card too weak?

 

I don't think so. It appears to just be a three phase brushless motor with integral encoder. Here is how the schematic shows the y-axis motor:
 

Looking up the part number, it is described as:
MHD041B-144-NP0-UN by Rexroth, Indramat, Bosch is a Synchronous Motor in the MHD Series. The MHD041B-144-NP0-UN features a Motor Frame Size of 82mm Flange Size, 50mm Centering Diameter and a Motor Frame Length of 2.7 Nm. This Motor has a Motor Encoder of Digital servo feedback and comes with a Output Shaft of Shaft with keyway according to DIN 6885-1 (with shaft sealing ring).

Thanks
