Nah, you'll be fine. the Hexa+ is not a great model, but it can supply the advertised values, it can do up to 385 watts on 12v.
Your GTX 1050 will use up to 75-85w on 12v, maybe a tiny bit more depending on the factory overclocking.
You'll have around 10w on 12v between the mechanical hard drive and the two fans.
You'll have maybe around 10-15w on 12v consumed by motherboard (dc-dc converter to power ram, other things)
So you're left with around 250w of power available for the processor.
the 1xxx series is not that power hungry - if you overclock an eight core Ryzen 1700x and set the voltage to max recommended of 1.42v , the cpu will use around 140w ... with the vrm efficiency (the dc-dc converter that converts 12v to 1.42v) to account, let's say 160 watts MAX.
You have a Ryzen 5 1400 which is basically half of a Ryzen 1700x and runs at lower frequencies by default , so without overclocking it's unlikely it will use more than around 60w. With overclocking, you're not going to go over 80w.
Basically, overclocking your cpu will only add around 20-25w to your current power consumption, which is around half of what your psu can provide. Your psu is decent enough that it can handle providing half of its rated power just fine, without you having to worry about it.
