Faulty power supply?

[Rocket Raccoon]

So when I was using my gtx 560 ti, it would crash and shutdown my whole computer if i played any game on high settings. Even on CS:GO i had to change the quality and other settings to low/medium. I thought it was the graphics card so i upgraded from a GTX 560 ti to GTX 1070. But even with this new card it will still crash and shutdown my desktop if i played any game on high. Now i know this isn't the GPU because its brand new. So is the Processor which is an i7 4790k.

If i use the computer to watch YouTube and such, it won't shut down randomly. It'll work perfectly fine. It only shuts down when i play a game on high settings. I was planning on buying a new PSU but I don't know which to buy and I am low on cash so i need to buy a good power supply for as little as possible.

 

My Specs:

CPU: Intel Core i7 4790K 4.00GHz

Motherboard: ASUS Z97-AR

Memory: DDR3 4x4GBs

GPU: Geforce GTX 1070

PSU: Kingwin ABT-750mm 750watts

 

 

This is my first post ever and not to mention i don't know how to correctly give my specs to others. Sorry.

What is your current PSU?

 

and budget for the new PSU?

Make sure its not OVERHEAT check your CPU and GPU temperature..

And tell us ur current PSU.

I forgot that. my bad.

My current PSU is a kingwin abt-750mm 750 watts.

How can i check the temperature of my cpu and gpu?

And my budget is around 70 US dollars. I might be able bump it up to 90 US dollars, but only if i absolutely need too.

CPU-Z to check the CPU temp . GPU Z to check GPU temp.

Make sure they are not too hot.

 

For the CPU if its below 50'C at idle then its good. even 55'c is good.

For the GPU if its below 40''C for modern GPU like 1070 its good. it its above 50'c then its probably not.

 

Since i never heard of that PSU i cant tell if its good or bad.

But i am sure its not as good as the cheap tier 3 cpu like corsair CXM series.

For a built like that. i am not going to use a crappy psu.

I highly recommend u to buy the famous EVGA G2 550w for such a high end built. its tier 1 psu.

Its $85 on amazon with free shipping.

The temperatures seem to be OK. so i'm guessing its the psu that's the issue.

Also whats the difference between EVGA G2 550w and a EVGA GQ 650 650w.

the GQ is about 15$ cheaper. Or should i just stick with the G2?

GQ is tier 2 PSU. its a good psu.

If u want that then go grab it.

But i personally would go for the G2.

 

Okay hows the temperature reading?
u must test it under load too.

While idle, the CPU was resting at 42'C and the GPU at 33'C.

But while running Valley Benchmark, Neither the CPU or GPU were able to reach 50'C before my whole system shutdown.

 

And i'll take your advice and grab the G2. Thanks for that.

 

But is this a PSU issue?

I also second the G2, it's worth the extra. 650W is plenty. I have a 2500K and a 980 Ti, both overclocked, and at full load I'm at 500W.

 

You might try taking the GPU out, and try running a stress test on the CPU (Intel Burn Test at max for 10 runs) just to see if it's a power issue (The CPU alone should not pull that much power).

 

That Kingwin PSU is a pretty bad PSU from what I've seen of the platform.

Thanks for the 2nd opinion.

Now i know to get the G2.

And i tried a stress test without gpu and it still shutdown on me so it is a power supply issue.

I am not sure.

In here i can easily troubleshoot it because i have a lot of spare component..

There's 3 common issues that cause a computer to shut herself down.

Whether its overheat,power failure because of crappy psu that triggering premature or immediate shutdown or short circuited.

It turned out to be the crappy psu. I'm buying the G2 on cybermonday. hopefully it'll be on a sale or something.

 

we'll see.

Yeah, the only other thing would be a dying motherboard, but usually that only happens to the prebuilt PCs...not your ASUS motherboard. My friend's prebuilt Acer that was used for 10 years...the motherboard would die randomly. We even used my AX860i and the PC still kept turning off (It's just a dual core AMD from way back in the day / no GPU)...turned out to the crappy acer motherboard.

 

Hope a better PSU fixes it though. My friend bought a equally as bad Thermaltake TR2 600W...it smoked up when I ran a stress test. haha.
