GPU Fried!?

pat, a good PSU should last 10 years.

Go claim cap aging and be done with it.

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.

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.

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.

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

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.

I go in this order of failure checks:

PSU
Memory
GPU
HDD
Mobo/CPU

In order of shit that usually craps out on me.
