🙁 Well, I was told that 16gb is a power hog, perhaps an exaggeration on their part. But maybe 16gb uses double that of 8gb? Is there a website calculator that anyone knows about?
There are plenty, but I'll tell you right now that memory doesn't use a significant amount of power. It's not an "exaggeration" it's just flat out wrong. Memory does not factor into power requirements.
This Question doesn't seem to be resolved except that you need to use a lower resolution so what is the resolution you are using for the PC games?
What? Where the hell did you get that? The computer should never shut itself off, no matter what the resolution is.
What is the monitor that you use, is it a 52 inch or a regular sized 27 inch screen? Some monitors require more input than smaller sizes.
This is not true. Size of the monitor has precisely ZERO impact. And let me cut you off, you aren't a victim of somebody's exaggeration, this is again just plain wrong. The only thing that matters is the resolution, which is totally independent of size.
Most Thermaltake 650 Watt PSU do have the 8-pin connector (for motherboard) and the 6-pin connector (for the video card), does your PSU have them?
You think he could power the system on without connecting the necessary power adapters?
Do you use more than one video out cable for a different purpose?
I'd love to see your explanation as to how this causes the computer to shut down.
What speed is the ram, is it in the list specifications or some OC brand?
Speed doesn't matter, memory should perform at the speed its rated for and not shut the computer down. I'm running a cheap $80 kit of DDR3-2133 at DDR3-2400. My computer doesn't crash. Neither do any of my friends who have high speed, overclocked memory.
First relevant thing you've asked, but it seems pretty unlikely as that probably would have come up by now.
Are the games you play verified for Windows 8?
*Facepalm*
Is your Windows 8 x32 or x64? OEM? Did you upgrade from a previous OS?
*Double facepalm*
Look, I get that you want to help, but just asking random questions and trying to pretend you know what you're talking about seriously isn't helpful.
Now, for some
actual troubleshooting.
Your problem is either overheating or power related. We've already ruled out the CPU overheating, so now we need to check the GPU. It is much rarer for GPU overheating to cause the system to restart (typically the GPU will just throttle itself), but it's worth doing a quick test anyway.
Go grab MSI Afterburner, install it and start up a game and play at the settings that cause these crashes. Afterburner will chart the temperature over time. After a few minutes of play, but
before your computer shuts off, tab out and look at the temperature graph. Anything up to 90C is considered safe. Above that and you're getting into the realm of overheating. Over 100 is pretty much guaranteed to run into issues.
If that's not overheating, we're probably looking at a faulty PSU. The best way to test this without having a PSU tester or spare PSU is going to be to remove as much stuff as possible from the computer, and see if the problem goes away.
If you've got multiple hard drives, disconnect all but the ones needed to boot and game. Disconnect all
case fans (not the CPU fan!), and all your optical drives. You should be able to get back about 50-100W depending on how much stuff you've got. Figure 25W for a DVD burner, 10-15W for an HDD, 2-3W for an SSD and 6-12W for a 120mm case fan and as much as 20W for very large fans like 230mm+. Leave all your memory modules installed, as they don't use enough power to matter and we don't want to introduce any more variables.
If you can run your games as normal with all this stuff disconnected, then we're dealing with a failing PSU, which you should RMA to get a replacement.
