Does it go black as in lose signal or go black as in loses power?
If it's the latter, then probably your electricity.

The Antec BP series are poor quality budget PSUs, so I'd be best practice to upgrade anyway.
its like power lose......bit for a second....whenever a switch on or off any appliance

If it's specifically power loss, it is most likely your electricity. As the PSU doesn't supply power to the monitor.

Regardless as per my previous comment:

And doing so will tell you for certain regardless.

I tried today by switching on and off appliance ... Screen only black for a sec only when connected to GPU 1660 ....When connected to MOBO it works well ....
