Pristine new machine crashes while playing demanding games.

First - specs:

  • graphics - MSI GF560 GTX-TI-M2D1GD5 - factory radiator and settings
  • RAM - Kingston HyperX 2x4GB 1600MHz DDR3 Non-ECC CL9 Intel XMP X2 Grey Series - factory settings
  • AC (620W) + computer case - Logic Concept AT-B040-10-LOG620A-0002
  • CPU - Intel CORE I5 2500K 3.3GHz LGA1155 - factory radiator and settings
  • HDD - Seagate Barracuda Green, 3.5'', 1TB, SATAII, 32MB cache
  • motherboard - MSI P67A-GD65 (B3) - factory settings
  • OS - Windows 7 x64 Pro

Now problem:

PC works like a charm until I try to play demanding games (Just Cause 2, Battlefield 3), when it just turns off after 5 minutes of playing. When I power it up again and try to play games, it turns off even sooner. No BSOD, just instant shutdown.

I suspected it was something with graphics, because even though MSI Afterburner reported 50 Celsius on GPU, it was 95 and rising (measured with laser thermometer, instead of games I used MSI Kombustor to force card to work). MSI replaced my card (after fucking month of waiting and no less than 3 calls from me) saying that problem was caused by "something with cooling", but it persist even on new card - this time temperature is measured correctly and card doesn't overheat.

Additionally, when using newest (306) nVidia drivers, they randomly stop working (afaik it's a fuckup on nVidia side, because older drivers work just fine).

I suspect two things - AC may be too weak, or cable from AC may not provide enough energy due to missing one pin.

These are my gfx card sockets, this is how one cord's socket looks like (one is connected directly to AC, all 6 pins are in place, second is combined from two separate cables).

I would appreciate even the smallest advice on how to solve this.

EDIT: welp, looks like something has gone even worse. Now randomly after powering rig up, I get horrible artifacts all over the screen, and if I try to run Kombustor 2.4, usual fuzzy graphic gets distorted after 10 seconds and whole thing crashes to hell (not powers down, just whole screen gets artifacts and PC doesn't respond). I'll try another AC (Chieftec 550W (GPS-550AB-A) - never failed me) and see results, but I'm not expecting success. PC is still on valid warranty, so I'll try to get it either fixed or refunded.

Are you sure? I read that 600W is enough for it, and I don't want to buy it just to have the same problems.

Stated maximum wattage is irrelevant if your PSU can't provide it reliably to spec. Power supplies are one thing where the manufacturer really, really matters. I can't find a single review of Logic's PSUs, and that doesn't bode well for their reputation. If they're cheaping out on parts in the name of affordability, they're probably providing filthy, unstable power that doesn't actually meet the label's guaranteed minimums. You're going to want something from a reliable manufacturer or OEM like Corsair (TX-series in particular), PC Power & Cooling, Seasonic, XFX (rebranded Seasonics), or to a lesser extent recently, Antec. Flip through some of JonnyGuru's reviews to see what determines a "good" PSU. It is the only thing powering every component in your PC and you really can't afford to skimp on it.

edit: and make sure you get something with two real PCI-E connectors; that adapter can't be helping the situation.

Always have more then it recommends. Try a 750, or go to a computer store to try the power supply, they'll help you.

check out a power supply calculator http://www.thermaltake.outervision.com/

I will try that, but is there any way I can test power supply for faulty voltage? I don't want to wait another month to discover it was not it.

Yes; a volt-ohm/multimeter. You can pick one up at a local hardware store, or sometimes even at Wal-Mart in the home improvement section, near the electronics department and lighting. You want to make sure you're getting readings of 1.5v, 3.3v, and 12v when you test the various wires (with minimum variance).

Feel free to refer to this chart for what is considered "safe/stable" outputs: http://pcsupport.about.com/od/insidethepc/a/power-supply-voltage-tolerance.htm

If you are planning on buying a new power supply, please make sure you buy one with 20 amps+ per rail. This is a very common issue that its not talked about all that much. Newer video cards only need 100+watts to actually run, but they real trouble is the amp per rail.

This is why most people started leaning to Corsair brand power supplies with lower wattage. They have high amps.

Enermax, Silverstone, PC Power & Cooling, Corsair and Seasonic are the top brands. OCZ and Antec are great too because they're pretty cheap. There are 7 brands here and lots to choose from. Stick with those and as long as the product is not DOA, you'll be fine. If you're willing to spend ~$70, Corsair is probably the best value in that range.

You only need a good 500-watt PSU to power your system. Get a 600 to be safe.

If you put your video card on a single rail by itself it should be fine.

Your PSU isn't good enough. PSU's are never at their 100% wattage. NEVER. Also the way you described your gfx card pins worries me. The first thing to check on any pc is the PSU, especially if the pc's dead or for graphical problems. I used to have issues with my 500w. Now that I have my Huntkey (Italics because them and Coolermaster are reliable brands) 700w PSU, I don't have a day's problems. Also, my system should run fine on a 500w. But it didn't.

Most likely the power supply. From what I can tell from google, that PSU came with the case. I cannot actually find the rated specs for the PSU, which really says a lot about the company. Can you take a picture of the label on the side of the PSU that lists the amperage of each of the rails?

I found this on their site, but I don't trust a single one of those numbers.

Mr_That_Guy•

I agree, that looks very sketchy.

Ah well someone else found a picture of it but here is my response to that:

If a manufacturer lists their wattage by the combined 12v+5v+3.3v rails, its almost always a very low quality PSU. If you have another PSU you should try that, or if you have a multimeter/voltmeter, try measuring the 12 and 5v cables. If the voltage is more than .1v above/below then you have a serious problem.

To be honest it actually sounds like over heating. Everyone has covered the PSU part pretty well but as an alternative, check your CPU/System temperature, you can fairly easily so this by going into the BIOS during boot up.

Normally it should float around 35C (Super good cooling), mine is 45-50, problems around 65C+.

When a system overheats, it will tend to shut down quicker afterwards if you don't let it cool down.

Cause could be bad fan, (make sure they all spin, and aren't limited by speed). Thermal paste is fairly common but I recommend getting an experienced tech do that if it comes it if you haven't done it before or aren't comfortable... Make sure no airflow obstructions but that's less likely a problem.

Power supply will also causes very similar symptoms but is harder to verify compared to quickly checking the temperature in the BIOS right after it happens.

Can't be overheating now - nothing goes over 45 Celsius while idle, or 65 Celsius on 100% strain.

It's either fucked up gfx card or AC.

To be honest, it sounds like either a thermal issue to me too, or a driver/firmware problem. A shutdown after only a few minutes of gaming usually points to overheating (system shuts down to prevent damage). Maybe the "dangerous" threshold is set low for temps.

But if those are your readings (and they're ACCURATE), and a driver update/alternate doesn't work either, then it is almost definitely the power supply.

Almost surely PSU providing power out of spec. PSU is the single component you should never skimp on. Only buy one that scores very well on independent reviews. Should be the backbone of any new system!

I think the general consensus is you have a cheap PSU (Taiwanese). Most likely with less than 80% efficiency, too. At any given time, those 600 watts may be dissipating over 120W as heat if that's the case.

Even so, it still comes down to quality of power supply. I always recommend folks check out the tiered guide for quality: http://www.eggxpert.com/forums/1/323050/ShowThread.aspx
