There are two issues here.
1. How much power is needed for a GTX1050ti?
Assuming that the card is not a factory overclocked version the spec says a max of 75w which should be ok for your psu.
The spec for your GT 740 is 64w.
About the best card that will run under 64w might be a GT1030GDDR5 at 30w.
Most of your psu output is on +12v so you should be ok.
2. Is there a potential problem with your psu from a quality point of view?
Consensus is that your psu is a cheap unit not to be trusted.
A cheap PSU will be made of substandard components. It will not have safety and overload protections.
The danger is if it fails under load, it can destroy anything it is connected to.
It will deliver advertised power only at room temperatures, not at higher temperatures found when installed in a case.
What power is delivered may fluctuate and cause instability
issues that are hard to diagnose.
The fan will need to spin up higher to cool it, making it noisy.
A cheap PSU can become very expensive. Do not buy one.
What to do??
Really, that is up to you, your budget, and risk tolerance.
Your I5-4460 is a nice processor that could game nicely with a card as good as a GTX1660ti.
That would want something like a 450w psu with an 8 pin pcie connector.
I like the Seasonic focus 450w with a 7 year warranty for $70
the 550w version is only $3 more
