GPU Fried!?

[ZERO]

So my computer has been crashing when running ns2 or cs:s preventing me from doing some work in the zm server.

So I run furmark to check and it instantly crashes. When the system reboots the alarm for failed GPU goes off in the cmos until I recycle the power again. Luckily, I can use it normally but it appears not to work for gaming... :banghead:

Going to run some more tests, I do not understand how this thing could go bad already as it has never even gotten over 50C even once! All my ram is good as verified by mem86+

Could be my psu as I am getting <11.3V on the 12V rail. This might also explain all of my computer problems recently! The psu has a 7 year warranty so I should be good for a replacement.

[ZERO]

Yep, PSU warranty time.

[StarsMine]

yes 11.3 is out of spec.

[ZERO]

Now when I test the psu under no load it reports fine but with the 3.3V out of spec reporting over voltage. (with the psu disconnected and hooked up to a psu tester that is.

[ZERO]

Got up to 160W load on it and still can not get the voltage to read out of spec. Perhaps there was a short or something that was corrected by swapping out the psu's...

[StarsMine]

What PSU is it?

[ZERO]

1.2 Kw pc power and cooling. It has a 7 year warranty so if I can find an actual issue with it I can get it replaced no problem.

I swapped it out with a 750W pc power and cooling silencer and then increased the stagger start up rate for my HDDs to prevent too much strain on the smaller unit.

[StarsMine]

I have a hard time believing you can stress a 750w psu without going trifire/sli
Pre/post OCZ?

Anyways you seem to have the issue under control, dont think I can be much help.

[ZERO]

System uses about 400W under no load with 50% of the cooling system turned off. I can only simulate 160W of load using the cooling system from a 10 year old system on the suspected bad psu but so far can not find anything wrong with it despite the fact that swapping it out has for now resolved my problems in that I can run furmark with no issue.

These psus are all pre ocz. The 750W I am using in here now is about 8 years old. Did not even have an 8pin gpu connector as I had to use a dule 6pin to 8pin adapter.

pat, a good PSU should last 10 years.

Go claim cap aging and be done with it.

[ZERO]

Problem is I do not have the money to ship it if I am wrong... I have some old computers so I will hook them up to it to eat some more power. Possibly I can find some more dead hard drives (I knew they would be useful someday) as those eat 10W each.

I wish there was more shit that just eats psu load that would be nice for testing.

Star, when the PSU you are using doesn't even have the correct plugs, it's time for an upgrade. :icon_mrgreen:

[ZERO]

The psu I was using did the one I replaced it with only had 12 6 pin pci-e connectors instead of the today standard 8 and then 4 8 pins. So just a change in pinout type, that is why gpus ship with an adapter.

[ZERO]

Yea testing watt level and I am not sure if it is safe to really use this 750W psu. The draw with GPU under 100% load is 650W and that is with cpu under 0 load. If both got load at the same time it will kill this psu.

[StarsMine]

How does a single GPU system pull 650 watts, I have a very hard time beliving that. Also remember what is pulled from the wall is not what the PSU is rated for.

[ZERO]

This psu is 85% efficient so that would be 650*.8= 520 est inertial watts. Remember that I have 10 7200rpm drives and a water cooling system and 20 fans. Remember still that the 480 uses more power then even some of the newer cards which are more efficient. Remember that I also use a i7 965 which is also more power hungry than todays stuff.

[StarsMine]

zero.....
PSU are rated on power it can give to the computer not on what it pulls from the wall

a 1kw PSU that is 80% efficient, will still give the computer 1kw, it will just pull 1.2kw from the wall.

A 750w psu will give the computer 750w, regardless of what it pulls from the wall.

All of what you stated will not pull anywhere close to 750w, Overestimating what parts pull @ load (300(gpu)+200(cpu)+100(hdd)+100(cooling/rest) is only 700 and thats highly overestimating pull.
Infact a 980x plus 480 only pulls 450w at full load, though I will admit thats with a SSD and not 10 HDD

[ZERO]

Like I said I got a meter right here that tells me the exact wattage (although I only got 50% of the cooling system on). To put in prospective just the fans for my old computer when tested drew 110W from the wall.

Also the 1.2Kw psu is rated for 92% efficiency.

Regardless the 750W appears to be getting the job done for now. Although I still want to validate that the 1.2Kw really did have a problem b/c even under 160W load I can not get anything other than perfect readings from it. Going to try to hook up another pc to it later and see if 100% load on that system with the existing 160W can push it up to 500W and test for failures, maybe even OC the i7 920 to draw some more for the test.

I do have a dual xeon system that could load it but the cooling system for that thing has failed after being left sitting for so many years with poor quality tubing. Perhaps if I dug up some air coolers for it though.

[Jackie Marlow]

I go in this order of failure checks:

PSU
Memory
GPU
HDD
Mobo/CPU

In order of shit that usually craps out on me.

[What]

Have you tried unplugging it and plugging it back in?

[Steamer]

Did you check your printer cables?

Also, agreed with Stars, if your PSU is pushing watts no load, something is wrong.

http://www.newegg.com/Product/Product.aspx?Item=N82E16817139003

This thing is pushing 4 HDD, 2 Optical Drives, 1 GTX 560, 4 sticks of RAM, Q6600 OC'ed and Undervolted (Pushes fine Overvolted), and 6 120 MM fans. Max load is pushing my breaking point (Not reached often). Mmmmmm efficiency.

[ZERO]

That is really not much load and are those even 7200rpm drives?

You easily pull my wattage with what I have nothing is wrong with the current psu. You guys realize I have a meter that tells me the wattage draw I am not saying in theory I use this much power I am saying as a fact I use this much power under load. Under no load I pull about 400W avg.

[StarsMine]

I dont care what you pull from the wall.
What I said was a 750W psu will provide (output) 750w REGARDLESS of what it pulls from the wall. Thats why I said a 1kw psu that is giving 1kw of power will pull 1200w IF its 80% efficient.

Honestly I dont have a clue what steamer is saying though.

[Steamer]

Yes they are Zero.
I read that wrong. I thought you meant he was hitting his peak with no load. I was having my first cup of coffee.

400W is a bit much no load what a leech your PC is lol.

If it's a good one, yes.
Most 1k PSU's will not provide a full 1k. They will say so, but deliver ~900 and pull ~1300.... lol. People should always invest in a great PSU. This is something most hobbyist's look over, and very much ignored as not a "major" component.

[ZERO]

Yea my 1.2Kw is rated to pull 1.4Kw max but yes the 750W had been preforming fine so far without issue.

As for the 400W under no load you got to keep in mind this computer has generally twice as much stuff running in it compared to a normal desktop so that is not really surprising.
