GTX 660 Causing computer to shut off

nathanburton · Jul 10, 2013

Hi I have just installed my new EVGA GTX 660 SC graphics card and when I try to play intense games like Bioshock Infinite, it causes my computer to shut off unexpectedly as if I had unplugged it. Is there anything I can do?
My pc specs:
FX6300 processor
8GB 1600 Mhz ram
xfx 500 watt psu
Gigabyte 78LMT-USB3 motherboard
Thanks to anyone who responds

Can you please give case, cooling and temps.

nathanburton · Jul 10, 2013

I have a vantage blue gaming case it has four case fans.
I only have active air cooling on my processor and graphics card.
When playing my gpu gets to about 68 degrees Celsius and then shuts off and my processor never exceeds 45 degrees Celsius.

nathanburton :

First, dust off all components, then monitor the gpu with precision x, if it gets hot turn up fan speeds. That temp is actually low though. I think the issue may be the psu. Feel if the Psu gets hot. With that case it may draw more hot air.

my computer is two weeks old so it is dust free and I dont think that the psu faulty as with my old graphics card (XFX ATI 6670 2gb ddr3) it was fine.

Check all connections, plug in any loose ones. The 660 may draw more power than the 6670 so make sure the PSU is still cool and that the fan is working.

Even though 500W should be plenty for a configuration like that, I'm also suspecting your power supply. How many hard drives and optical drives do you use?

Just wondering about something else, did you remove the old AMD drivers properly before installing the 660?

ThomasJ93 :

I have one 1tb 7200 rpm hard drive, one 24x optical drive and the four case fans may draw a lot of power.

ThomasJ93 · Jul 10, 2013

They wouldn't draw so much power that the system were to shut down. Do you have any of the components overclocked?

ThomasJ93 :

No I dont

This really sounds a lot like a power issue - power supplies are designed to auto shut off if they get too hot/overload. If you have a way to borrow someone's power supply (I am assuming you do not have a higher wattage one laying around..otherwise you would be using it), give that a shot. Otherwise, if you happen to have a lower end video card laying around that could still play some of the games you experiencing auto-shut offs with, try that. If you can pop in a lower end video card that doesn't cause your computer to auto shut off, I would say it's certain your PSU just can't handle it either because it's faulty or just not pumping enough juice.

Yeah it probably would be the psu as on my old graphics card running the same game (6670) it never shut down. Is this psu a suitible one.

Corsairs are very reputable. That power supply has solid ratings.

Oh, by the way. Before you spend extra money just to rule out the possibility of bad memory, give this a try.

i Second the idea that your PSU is the Issue. what is your 12v Rail rating?

ko888 · Jul 12, 2013

How can you have an XFX 500 Watt PSU when XFX doesn't even have a 500 Watt model in their lineup?

The EVGA GeForce GTX 660 SC draws less than 11 Amps from the +12V rail so it's not a particularly high power consumption card.

Even a good 400 Watt PSU would be able to power your system configuration as long as it has a +12V continuous current rating of 26 Amps or higher and has at least one PCI Express supplementary power connector.

ko888 · Jul 12, 2013

nathanburton :

The total power consumption of all of those devices should be under 60 Watts.

Upgrader011 · Jul 12, 2013

ko888 :

actually the GTX 660 SC minimum requirements is a 400W PSU with a 24A 12V rail

edit: 450W PSU

ko888 · Jul 12, 2013

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most important factor.

Upgrader011 · Jul 12, 2013

ko888 :

yes i know that. but you said the GTX 660 needs a minimum of 11A on the 12V rail. it actually needs 24A

ko888 · Jul 12, 2013

Upgrader011 :

That's incorrect. I said nothing of the sort.

The EVGA GeForce GTX 660 SC has an actual measured power draw from the +12V rail of less than 11 Amps while running Furmark.

You're talking about system power consumption which includes the power draw of the graphics card.

The general system power estimating formula used by NVIDIA for GeForce GTX 6xx series cards is to take the maximum +12V current of the card during typical gaming and adding 15 Amps to handle the rest of the system (i.e. 130W TDP CPU, motherboard, HDD, memory, etc.). It is not always followed exactly but it is always close.
