XFX HD R7770 Double Dissapation 1GB causing PC to shutdown

Yubersan · Mar 17, 2014

My set up is as follows:

Intel Core i5 3570k Quad core 3.4GHz
XFX HD R7770 DD 1GB
Gigabyte H61Musb-3v Motherboard
450W PSU
1 x 500GB HDD
1 x 750GB HDD (both Seagate Barracuda)

I know that my motherboard and GPU aren't exactly spectacles in the pc gaming world, but my gpu, even with the games it is supposed to be able to run, will cause my pc to shutdown almost automatically (whilst playing). It only pauses to show a black screen before it turns off.

It's clock speed is set to a default 1000MHz which is adjustable up to 1100MHz.
It's high performance memory clock settings is set to a default 1100MHz adjustable to 1300MHz max.

Is there a reason for these shutdowns, other than the fact that my card isn't the greatest?

Thanks you in advance

TheN00bBuilder :

This PSU is WAY overpriced and WAY too much. For $35-$45 you can get a HIGH quality 450w unit which will be more than enough power.

What 450w do you have?

Oh, it's actually 500W sorry. And it's ace ATX power supply

tiny voices · Mar 17, 2014

Ace is junk. That PSU is very low quality.

Replace it with a 450-500w unit from Antec, XFX, Corsair (not CX, CS, RM), Seasonic. I would not recommend EVGA just yet. They have some decent units but also some other not so good ones and they are too new to know about longevity yet.

So, with buying a new PSU, my gpu should perform better?

tiny voices · Mar 17, 2014

Yes, your PSU is the reason your computer is shutting down more than likely.

Thanks for your help

tiny voices · Mar 17, 2014

No problem. Always glad to be able to help!

I have another question, with something else that I have noticed, my gpu temp rises to 100 degrees C (plus sometimes). That isn't normal is it? Or is that again a result of the psu not providing it with enough power?

tiny voices · Mar 18, 2014

That has nothing too do with the PSU. The card could be overheating. Do the fans on the card spin?

Yubersan · Mar 18, 2014

Yeah, they spin. When I change the fan control % you can hear the change too. So they definitely work ok

tiny voices · Mar 18, 2014

What program are you using? The program could be broken. Use MSI Afterburner to check the temps. It is VERY reliable and works with all cards.

Yubersan · Mar 18, 2014

AMD Catalyst control center. Comes with the card. I'll do that, thanks

tiny voices · Mar 18, 2014

100c is close to burn for these cards. If that is true, the card is defective. Let me know what MSI Afterburner thinks.

Yubersan · Mar 18, 2014

I'm not exactly too certain on how to use it, but with every test set to it's default testing parameters, the gpu temp will reach that after a minute or two. If that.

Yubersan · Mar 18, 2014

However, I did buy a new psu. The guy recommended a silverstone 500W for my rig and it is now playing games without shutting down. It also appears that, using both AMD catalyst control center and msi afterburner, the gpu temp has gone down whilst playing games.

tiny voices · Mar 18, 2014

The PSU was junk. I assumed this was the issue. The temps were not actually that high. It just read that way as a fluke.
