Hello! I am new to the PC gaming community and I'm planning on upgrading my Pre-Built HP Pavilion p7-1436s with a new Motherboard, CPU, and GPU. These would be the specs:

CPU: Intel Core i3-6100 3.7 GHz
Mobo: GIGABYTE GA-H81M-H
GPU: Zotac GeForce 1050 Ti Mini
RAM: 8gb 1600mhz
PSU: 300W

I've left the PSU and RAM exactly how they were when I bought this (fairly) old PC. Should I upgrade my PSU? I've heard from people that 300W won't really get you anything, but I need an answer specifically towards my build. Thanks!

First, something is not right, the mobo you have listed is socket LGA 1150 while the CPU is a socket LGA 1151 . Not possible, they are incompatible.

One of the issues here is PSU build quality, not all 300W PSU's are the same. I will guess that HP has provided a basic PSU and you are probably in the range of 250W system requirement. All power systems see voltage spikes that go outside of normal operating range. Cheap PSU's do not handle voltage spikes as well as good ones, so being close to the limit makes the likelihood greater that the PSU will not handle these spikes. And as PSU's age they degrade in power handling capability. And when cheap PSU's fail, they often take half of the other components with them.

I would seriously...

I would seriously consider a new 350W or more PSU.
