Moniter, keyboard, and mouse have no signal after installing a new GPU

[andrewmakayla20]

I just installed a new graphics card.
The PNY 1050ti and I get no signal to moniter and my keyboard and mouse. I tried my old GPU and my computer started just fine! HELP ME please. Maybe it's my power supply?

Andrew please answer questions in the forum not in provate thank you

Andrew Im'ed me "my power supply is ALLIEO 350W "

1. that power supply does not have PCIE connectors to power the video card
2. that power supply is a <65% efficiency so a very low quality 350w PSu, making in reality a mere 12v@23a = 156watts, and that is way under powered to run that video card, (reference: https://www.newegg.com/Product/Product.aspx?Item=N82E16817154012)

solution get a new power supply that is moderns 80+ bronze or better at least 450w/550w

So would an EVGA 600W work?
