Gfx cards keep dying could it be the PSU?

38 posts in this topic

My sapphire 280x toxics keep dying and not sure why well the memory screws up heres the video

 

 

i have antec truepower 650 and is about 3 years old, cus it requires 2x 8 pin connectors ive bin plugging another cable into my PSU on a different 12v rail (think its a 25amp one) so there 2 cables, main one is running everything and 1 8x pin connector, 2nd one is running just the 2nd 8 pin connector on it. is that ok to do and isnt over volting it or anything? or could it be that the 2nd 12 volt plug is killing the cards??

 

any help would be good

You said "cards". This isn't the first card that this has happened to? Same symptoms?

Could be PSU, could be insufficient cooling.

System requirements: 750W (or greater) power supply with two 150W 8-pin PCI Express power connector

System requirements: 750W (or greater) power supply with two 150W 8-pin PCI Express power connector recommended

 

doesnt need it for example, steam boxes with i7's and 780Tis have only got 500-600w PSU's in... besides running a 280x MSI gaming edition that i bought whilst the toxic got sent back to sapphire runs flawless although running off the 8 + 6 pin. i did try running it completely off the other PCIe connector and did notice a little graphical glitching so turned it off put it back on first one and is fine so maybe its the PSU?

 

also when they test it back at the shop it crashes there drivers out and everything so its not the PSU wattage cus theyll be running 850watts. What if its providing unstable power? could that damage memory

Geforce GTX 780 Ti: 600 watt or greater power supply with a minimum of 42 amps on the +12 volt rail.

 

Radeon R9 280X: 600W System Power Supply Requirement

 

You may have already damaged your 3rd Radeon R9 280X by not giving it enough power.

By the way, do yo have the Antec True Power Trio TP3-650 650W or the Antec TruePower New TP-650 650W?

 

The former can only provide 650W MAXIMUM POWER while the latter can provide 650W CONTINUOUS POWER.

well the toxics die when i have it plugged into a second slot first is 22amps second is 25 amps = 47 amps. the 280x i have now is the MSI gaming edition its the low end one and is completely fine on a 8+6pin, its just the toxics die when i plug it in with the 2nd cable i think

 

dunno its 3 years old its probably maximum power

If the maximum power is 650W, then this PSU definitely won't work with that graphic card.

 

I don't know what your are arguing about.

 

I already told you what the problem is.

 

Also, I recommend that you buy a reputable brand 750W continuous power PSU.

Yes unstable/fluctuating power supply can damage electronic components.

 

Best to go with the GTX manufacturers requirements and also not all power supplies are created equal, so the steam boxes with 600W PSU's may be able to run the cards fine but I'm guessing they put a fair bit of research and testing into it to make sure it did so without affecting other components. PSU's also have peak or maximum power vs avg power labels, some 600W PSU can go much higher in Wattage temporarily under heavy load but thats when the PSU wattage label indicates rms/avg/continuous power while others that are 600W peak/max can only max out at 600W.

ah right ok fair enough.... now the decision is take it back and get a refund, and keep the money for a Star Citizen upgrade next year seeing as this MSI 280x is doing fairly well (the Toxics do consume alot for power than this think it might be extra 50 watts or someat) or take it back get a replacement and get a new PSU hmmm

I just want to note that I cannot find the +12V rail requirement for this product.

What is the Steam Machine's PSU?

 

Maybe it has a 600W continuous power PSU with a maximum power of 750W+?

Not to derail the thread but Gfx card manufacturers seriously need to do a better job of getting power requirements in check. Its crazy in this day and age that these things have to take up so much room inside your case, not to mention causing the lights in your house to dim and your garage door to open when powered up!

Im pretty sure this is mine, review date was from march 2010 i bought it december 2010 so im certain it is  http://www.expertreviews.co.uk/psus/276565/antec-truepower-new-tp-650

 

It seems to be the continuos power,   Antec TruePower New Modular 650W '80 Plus Bronze' Power Supply thats the PSU off my order so seems like its 650watt continuous power one

It'd be unlikely to get component damage with an insufficient/underpowered PSU. The fail-safe circuits on the PSU are going to trip and shut it down if you overdraw current and your computer is going to BSOD or something like that. It's not just going to randomly artifact.

 

Either you are getting faulty GPUs, or the converter is bad (I think think you are saying you have a converter for the second GPU?), or the PSU is bad, or the board is bad.

i havnt got a second GPU what i do is with the toxic as it needs 2 8 pin connectors, i plug the first one in then get another PCI express cable plug that into the PSU and plug that 8 pin one in the GPU to, not sure if there someat wrong with the second cables port or something

Oh okay, I see what you are saying now: 2x(6+2) pin connectors are needed for the single GPU, and a converter from molexes->6+2 is used since your PSU doesn't have the needed cabling. I don't think the converter does enough to be broken to be honest. AFAIK, it's a 1-to-1 map of the molex pins to the output pcie pins. So, I'd be more inclined to blame the PSU or the board itself.

think it is the PSU so ill just stick it out till Star Citizen comes and get a new one then when i get a new gfx card... how big of a PSU would i need to say run 2x 780Tis?

3 faulty GPUs? Seems highly unlikely.

It sounds like the user is incorrectly installing them. Although I find that hard to believe too.

I didnt see the videos but could you make a video of you installing the (forth) video card?

It does seem unlikely. I'm guessing there is an electrical issue with the PSU and it is rippling heavily on one of the lines. There is the possibility of intermittent short in the converter though I suppose, but I'd really question how those could be screwed up.

I don't follow closely and since the companies rate by whole system power it is hard to tell. I would use something like this to gauge probably:

I build my own computers mate, the 280x i have in now is using the 8+6 pin connector off the primary cable, i tried using the second PCIe cable only for the 280x in now and did start to see a few wierd glitches so i turned it off and put the primary cable back in and all is fine now so i think it might be something to do with that. i should of tried using the dbl molex to 8 pin connector but forgot and seems to keep frying them.

Newegg says 627 watts but people say this one is better http://extreme.outervision.com/PSUEngine says 500 watt recommended + bout 40 watts for the toxic = id say 550 watt
