so recently i upgraded my cpu to an r5 1600 to do this i had to change my motherboard and ram seeing as i didnt have the right socket. I finished succesfully and the pc booted up fine.
but as i tried new games and ran a benchmark it turned out that my pc was under performing and some simple games kept crashing that didnt crash with my old cpu for example gmod b04 etc.
the only thing that really needed an upgrade at this point was my graphics card which is a 1050 ti
i remembered reading about how a cpu power cable that only had 4 pins that went into an 8 pin header could cause the mother board to "lock down" in a way or not function at its full potential.

is this the reason my pc is crashing simple games and games tht have never crashed before? and should i get a cpu power cable extension that has 8 pins or is it time for a psu upgrade or is there something wrong with another component?

as far as im concerned evrything else in my computer runs smoothly like my ram gpu and cooler

any advice or answers are greatly appriciated

There are tons of old drivers and other os optimizations that are set up for your old chipset and processor, none of which work with new setup, so it can actually be worse than the old build sometimes. Additionally none of the new chipset/instruction sets for your new cpu are being used since it still has the old stuff mixed in. Also lots of driver conflicts mixed in.

If the motherboard has an 8 pin CPU power connector then you should be using an 8 pin connector or you may not be supplying enough power to the CPU.
An adapter might work but I don't like suggesting them as it's risky, you can draw more current than the cable is designed for that way and the PSU might not be up to it either. Really it's best to use a PSU that has the right connections. So yes I think that it possibly could be the problem.

But as Suphos suggests that may not be your problem, you didn't just upgrade your CPU you essentially built a whole new PC and for best results should do a fresh install of windows on it (if you haven't already).

The aux cpu header is needed to give added 12v power for overclocking and for graphics cards.
Sometimes 4 pins is sufficient. Your graphics card is not overly power hungry so I might have thought you would be OK.

What is the make/model of your psu?
If it does not have an 8 pin cpu cable, perhaps it is not strong enough.
On a good quality psu with sufficient wattage, I might use an adapter.
On a cheap psu I would not take the chance that it might fail under load and damage your parts.

Just to throw another spanner in the works, Ryzen can be picky with RAM speeds and crash a lot due to that, what RAM did you get and what speed is it set to?. With my 2700X I chose the wrong RAM (SniperX DDR4 - 3200 - meant for intel really) and had to play around with the speed to get a stable system, several games were crashing with it at stock speeds but at 2933 it's rock solid.

i did not install a fresh version of windows for starters as it booted up with windows already installed so i thought i be alright i could try this but my relative once done the same thing on his computer which for some reason never functioned the same again so im a bit hesitant to try it unless someone can explain what happened with his system


as for my psu its an evo labs 750W bronze so am i right to assume it could handle the extension?

and my ram is a corsair vengeance LPX 2x4gb ddr4 at 2666mhz
if the problem did lie in the ram how would i change the frequencies? i didnt even know that was possible to be honest

and if it helps my motherboard is an Asrock ab350 pro4


this is a reply to all the answers that ive recieved
and thanks for the help so far

Where do i find that? sorry but i have little to no knowledge on psu's

Take the side panel off your PC case, there should be a large label attached to the side of the PSU. It will have a table that lists how much current it can supply at each different voltage. Should look something like this:

You want to look at the amps for the 12V rail. If there multiple 12V rails (12V1, 12V2, etc), you want the combined amps/watts for all of those rails.

ok well theres two rails each at 22A

yes i will do that probably tonight
but out of curiosity, do you have any idea as to what happened to my uncles computer?
he reinstalled the windows and afterwords the thing went into a full down spiral in performance

That "750W" PSU is only rated to output 528W on the 12V rail, which is where the vast majority of power comes from in modern PCs. Having 12V power so much lower than total rated power is often a good indicator of a junk PSU.

I'd try reinstalling windows first, but replacing your PSU would be a good idea regardless of whether it's responsible for your issues. A *good quality* 450-550W would be fine for your specs.

sorry for the wait i was a bit busy
so i reinstalled windows and i am noticing a bit of a change in performance,definitely better but i ran a bench mark and while it was performing at average speeds it was still marked as underperforming tho the only real problem seemed to be the hard drive
would it be a good idea to invest in an ssd first or should i change the hard drive?

You can see on the marks that while my cpu is still good its still kind of low compared to others, maybe im too pushy but i really want the best possible performance from everything

i already re installed windows lol

and it did bring the performance up but not by too much
