Cpu Overheat? Or PSU Issue?

Recently I just bought new computer parts for streaming. The build is an AMD FX 8350 8 Core With a Nvidia gtx 750ti Gpu 20GB RAM and a 970MSI Motherboard. I basically got a new case with 3 fans, all stock, and built the computer. After attempting to stream any longer than about 15 minutes, My computer shut down and I would smell something burning. The ATX cable I had connected to the motherboard had begun to melt. A couple of big mounted parts next to the processor were very very warm as well. However Cpu was only using about 30-50% when it seemingly overheated. I have extenders connecting the atx cable to the motherboard since the original cord itself was too short. So is this due to a Processor overheating and I need a new cooler? Or is this due to a PSU or ATX cable issue and I need to replace the PSU? Would a mekting ATX cable cause the cpu to shut down? (It shut down twice, only visible damage is the melted part of the ATX Cable extender)

A good quality power supply won't need an extender like you had in your original one, they would have cables that were made to be used in tower systems. I'm guessing the power supply you were using came from an OEM computer where the cable length was only made long enough to use in that particular system. That can very well also be the weak link in the system. At least the system runs, you were lucky that the motherboard and CPU are OK after what happened.


It's pretty much guaranteed to be a power supply issue. The brand actually got some decent reviews, so it's not as bad as I thought but you'd still need to replace it. The issue may be also end up being the motherboard and possibly CPU were fried as well.

Any power supply from tier 1 or 2 are best from this list http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html Tier 3 should also be OK with your lower power video card, just make sure you get a one with enough wattage so you are not near the limit of the power use, 400+ watts.
 
Thinking of getting a Thermaltake TR2 600w that should be good? My only issue with a new supply is that I need it to reach across the motherboard to plug in the 8 pin connector, but I don't think anything else has fried since the computer works perfectly unless I stream.
 
I can't be spending much more than 45$-50$ I'm just in best buy looking around not sure if all they have is crap, I just need a psu that won't shut the computer down
 
Either corsair CXM 750w or CXM 850w.
For your PC, it should only draw around 300W power, so add some headroom, even the 400W or 450W good brand PSU will be good enough. The brands are XFX, SeaSonic, super flower, and some of Antec, evga, corsair, etc.

Okay I'm gonna give the evga a try, worst case scenario I return it, this is my first time basically building a computer so I should have thought that the stock psu would need to be replaced as well, hopefully no more issues, I'll come back with the results
 


Pretty much the #1 thing we see with posts on here are systems using poor quality power supplies. The power supply is what runs the whole computer, yet many builders just look for the cheapest cost per watt, risking every part they have if the power supply fails.

The issue is that those people, like yourself LOL, don't ask questions till there is an issue, at which point it's too late. Say failed hard drives, which is another big thing we deal with, posts are often "I need to recover 10 years of my baby pictures and my dead parents pictures!!!" and of course there are no backups. At that point, just like with a burning computer, it's too late unless you spend a lot of money on professional work.
 


We'll thankfully I came when I did, I knew there was a risk of frying things which is why I didn't turn it on until I switched out the psu as you guys suggested, so thank you, you guys are the best.
