I own a fairly inexpensive PSU, the one listed here: http://www.microcenter.com/product/45741...wer_Supply. I have my R5 1400 overclocked to 3.65Ghz and aim to reach 3.8Ghz. However, whenever I run the Prime95 test on all 8 threads for about five minutes, my monitor and mouse shut down while the PC keeps running. I’m curious if this is due to the PSU and whether upgrading to a better one would help?

be aware that each chip is unique and you might have reached the maximum capacity of the one you received. the motherboard could also be a limiting factor, possibly not providing enough power to the CPU you're targeting. with all these variables involved, it's difficult to pinpoint exactly what's restricting performance. having a 2000w PSU doesn't guarantee everything will work smoothly for overclocking. check the reviews on this site and others, as results can vary significantly. tom recently compiled a comparison of several Ryzen CPUs and found different outcomes even with the same setup.

A reliable power supply ensures all computer components stay safe. A faulty one can cause damage. You may need higher voltage for your OC to work properly, plus extra load on the PSU. There are hierarchy charts for PSUs available. I recommend choosing one that has been tested and rated by experts.

it's not just about the rated watts on the label. it's more about the power quality and stability. this evga unit isn't the best, but it's not meant for overclocking. it would work better than the thermaltake you're considering or the 650w model if you're willing to spend a bit more.

a decent psu for a budget build and it should manage the oc load adequately. the required power depends not only on the cpu but also the gpu and other components. probably 550w is sufficient, but knowing your full specs would help confirm

I own a fairly inexpensive power supply unit. This one: http://www.microcenter.com/product/45741...wer_Supply
My R5 1400 is already overclocked to 3.65Ghz, but I aim for 3.8Ghz. However, whenever I run the Prime95 test on all 8 threads for about five minutes, my monitor and mouse shut down too, while my PC keeps running.

It seems my monitor and keyboard might be entering sleep mode. Since the PSU isn’t providing power to the monitor, it can’t be the cause of the shutdowns. Although this PSU isn’t ideal, it’s not terrible either. I definitely think a more reliable PSU would be better for serious overclocking.

My specifications are as follows. Your team's suggestions were really helpful.
ASRock AB350m Pro4 Mobo
GTX 1060 6gb PNY XLR8 EDITION
2x4gb 8Gb DDR4 2400 Ram
EVGA 500w 80+
3x 1 terabyte hdd's
R5 1400 @3.65ghz
I think I’ve reached my limit with overclocking this CPU, as I can’t exceed 3.65ghz.
I attempted to adjust the voltage between 1.35 and 1.40, but using realbench and Prime95 caused crashes on my monitor, keyboard, and mouse, though the PC kept running.
Now I’m planning to set it at 3.65ghz instead.
Thanks for all the advice, I was hoping to push it a bit higher, ideally around 3.80, but that’s not possible.

It seems like you're comparing yourself to your motherboard.

If you see something on a chart that looks good there is usually a test report or article about it. Then you can see if it makes or in some cases exceeds it's rated power. If you stick with one tester you can expect the results to be comparable.
There really is no standard test. Mfg. can make up their own tests and say whatever they want. GPU makers have lists of approved PSUs also to protect their products.
