GPU has a killzone somewhere around 500-600w got a question about under/clocking/volting

[Joe Brainer]

It will be another 7-10 days before I can get a good power supply to safely power my new GPU that is replacing my old one that my current GPU likely killed with its terrible ripple and awful 700w ability. My old gpu with my pc would pull 500-600w at full load. Which is what GTA V would do, and that's when it died. It looks as if it got some power in ways or in measurements that it shouldn't have. The night before I was playing a game that would run my system at about 60%, and for two weeks straight, before it died. 

 

Is it possible to put my new card in and undervolt/underclock the hell out of this 780 so it will use as little wattage as possible, just enough to give it the strength that Minecraft needs to run. Only for 7-10 days. Or would it still be too risky? 

[Windows7ge]

If the GPU was pulling 600W it would catch fire and explode. Now your entire system under load might pull 600W. To answer your question. MSI Afterburner has a OC menu that with unlocked voltage control you can drop the core/mem speed & core/mem voltage by about 50-100mV which is quite substantial.

There is not a single GPU on this world that pulls more than 300W, let alone 600W. Your PSU is just cheap trash. Sorry fam.

*cough* R9 295x2 *cough* is a single card that pulls 500W+ from the wall :3    that's about as close as it gets.

 

But yea, more than likely the powersupply is the problem here, not the gpu.

He has a 780 First of all, second, he said single GPU, not card.

My old GPU is dead, my old GPU and system would pull about 500-600w from the power supply under 100% load. My cheap power supply likely killed it, this I know for almost certain. I have another topic on here discussing the Power Supply and how trashy it is.

How did you measure that 500–600 Watt draw?

 

If you know your PSU is faulty and that it's likely killed a video card before, the last thing I'd do is connect it to another one. Undervolted or not, it seems like a terrible idea. I don't think I'd even leave it connected to the rest of the system. Just be patient and wait for a good PSU. If it kills another video card I assume you'll be waiting longer than 7–10 days.

Friend had a wattage meter when I built my PC. We ran it at 100% and we got somewhere around 500-600w, I cant remember the exact number. I know it wasn't above 600 or below 500. 

 

That's the answer I'm looking for too. I just need opinions on how safe or not safe it might be.

Not a single GPU

[DXMember]

there's no fucking way you pull 600W on a single GPU without going subzero

thre's no fucking way you pull 600W total system power with single GPU

still a single card, he has bolded and underlined "card"

either way it doesn't pull 500W

Tom's Hardware was running two of them in quad fire on a sindgle 1000W PSU maxing out about 1100 from wall for total system

and they also run single 295x2 off 500W PSU maxing out about 470W  DC on a bitminer

A far cry from the OP's 600-700W

Was this the system in your profile, the Phenom II x6 1055T + Radeon HD 6970?

 

That system is going to draw a bit more power than we're used to seeing from a single-GPU gaming PC these days, but still, you could put two of those cards in that system and probably still barely break 600 Watts under load. I don't know what happened, but I don't think that reading can be accurate.

Those, although generally accurate, don't count for PSU efficiency and other stuff plugged into the socket that cause interference and all that. Realistically you were using like 80W less than labeled by the readout (PSU efficiency) and your PSU was dying earlier than you though. A 780 might get you to 450W with some hefty overclocking which would make sense with efficiency of your PSU calculated in there.

His PSU is a "950W" Deepcool unit. OP PM'd me and is going to replace it soon.

Which is why I made super duper certain to bold, italicize, and underline the fact that it was a single card, not single gpu

Just had to be cheeky and point out that there is technically a graphics card out there that pulls a bit over 500W from the wall.

Depends on the scenario fam

Single GPU's can pull upwards of 1500w under the right circumstances

[Joe Brainer]

It doesn't matter anymore guys. I'm just going to bear it and wait another week. I've been dying since my old GPU died, can't really hurt for one more week. The 780 needs more than twice the amperage than my old one does, I don't want to risk it.

750 Ti pulling 1500W through PCIe?

The 640 CUDA cores that could.

The thing is if OP's PSU is crap, it's likely to be overrated by a bunch and in reality only be able to give 450W before going out of spec with ripple and killing your silicon
