PSU Troubleshooting - Computer Shutoff without warning

[Gurture]

I am fairly sure that my problem lies in my PSU however before i go out and get a new one, I want to find out if there are any ways I can properly diagnose what is causing the problem.

 

I have a 600W thermaltake PSU and it worked fine for a little over a year until about a month ago. My computer will shutoff without warning to blacksreen. I have noticed some patterns. My computer only will shutoff if it is under heavy load (playing graphic intensive games). I have not had it shutoff while idle. I do not think it is related to over heating as I have had cases where it has shutoff while it was relatively cool and a case where it was considerably hot and did NOT shut off. I have been turning down my video settings and it shuts off less frequently. I also made sure all power and data connections are secure. I have recently formatted my hard drive for unrelated reasons and it still shuts off under load. 

 

My components include:

Power Supply: Thermaltake 600W Model: TR2-600NL2NC

Processor: AMD FX 6300 Six Core processor 3.5 GHz

RAM: 16 Gb 

Graphics card: EVGA GeForce GTX 970 SC 

 

I just want to find out any way to diagnose the problem

 

I was looking to buy a Sentey ERP750-PS 750W Power Supply as a replacement as it is a well priced and readily available option. Would this suffice as a replacement?

Please tell us the load temps, not just "relatively cool" and "fairly hot".

And check windows event viewer, it will tell you why it shut down.

I wouldn't use either of those PSUs. TR2 are not great units, and I've never heard of Sentey before.

Okay I just tried to run a game to do a load test and my computer shut off while loading the game. I mostly shuts off in the middle of gameplay but it has happened during loading before. The max CPU temperature was only 29 Celsius. I also looked at the Event Viewer and took screenshots of the event.

Okay, what PSU would you suggest? I'm looking for something cheap because I'm a little low on $$. I was looking for PSU with around 700W just for head room but I do not know what is an ideal Wattage.

Where are you shopping from and how much is your budget?

Well I live in the Caribbean so I'll have to shop online. If it's on amazon then that's great! I do have some local computer stores but they don't carry much variety. My budget is max $100US if I can get anything good at that price.

Great deal on for these right now. Rock solid PSUs
