Power supply died after installing new gpu

To start, I recently bought a gtx 970 graphics card for my pc. I hooked it up and started a high performance game to test. It was running pretty good then my computer just black screened. Not even a bsod, it just went black. I checked to make sure everything was seated right, and then attempted to turn my pc back on. I got no response. I can’t get power to the pc, and I am afraid I may have shot my power supply as no status light turns on.

Here are my specs.
16gb 2400mhz ram
Amd fx-8350 processor
Msi gtx 970 graphics card
550 watt lsp lltra power supply
Msi 970 gaming motherboard
1tb hard drive

I think that’s it. I may be forgetting something.
My first thought was that maybe my motherboard can’t support the gpu. Or maybe I overloaded the power supply, but I don’t believe this is the case.

update: I tried the paper clip test on my power supply and found that it would not turn on.

Any suggestions would be great. I'm at a loss on what to do besides get a new power supply.

Thanks

    I'd say you've pretty much narrowed it down with the paper clip test. Your PSU is shot and a new one is the only way to go.

    If you really want one more test to see if it's the PSU or not, try the PSU in a different outlet and try the clip test again. If you get the same results you can safely bet you need a new PSU.

    Make sure you go for a 650W or higher PSU, also I would suggest getting it from a 1st or 2nd tier manufacturer as the 3rd and lower don't always provide the Watts they claim.. gonna try and find a PSU list for you, all my links and bookmarks are gone right now ;)
  2. If you did the paper clip test correctly and got no response, the PSU is obviously not working. What was the make/model of that 500W?
  3. you said 550w psu, did not mention the brand. is this one of those that comes free with the case? if so, then that is the mistake. those cheap psu's cannot run high end gpu's.

    if that is the case you are lucky to have the psu go out instead of your gpu or other parts
  4. same happened to me when i bought the new 970 gtx with 4 years old 450w psu . was playing and after 1 hour .. same story. it was the psu
  5. Lsp lltra 550 watt atx power supply.

    Also how do I know that my gpu won't take out my new power supply. Is there a test I can do. I also don't know if I fried my motherboard. I haven't tested anything for functionality except the power supply.
  6. high end gpu's require good psu as they can consume lot's of power.
    also, with a gpu as expensive as a 970, you should really get a quality psu.
    having a crappy psu is like making dirty blood run thru your veins

    I'd say that El Cheapo PSU couldn't take the load. It only has a single +12V rail rated at 30A/360W. http://mail.ultraproducts.com/product_details.php?cPath=103&pPath=653&productID=654
    ...a bit light for a "500W". Besides, the Ultra LSP is not a good PSU. It is in the last tier of this chart, the "not recommended" tier: https://community.newegg.com/eggxpert/computer_hardware/f/135081/t/45344.aspx?Redirected=true

    Well, unless you have another computer to test your video card in or where you can pull a power supply from, you won't know if your video card and motherboard are okay. You need a new, better power supply, and as someone suggested, go with 600 watts or better and make certain it has the amps necessary to run the GTX 970.

    The more powerful the video card, current models above the GTX 750 for example, one has to start paying attention not only to the size of the power supply but the amps required by the video card from the power supply. For example, a single +12volt rail power supply must be able to deliver at least 28 amps off that rail to support a GTX 970 video card. The power supply manufacturer will list something like this: +3.3V@25A, +5V@25A, +12V@83.3A, -12V@0.8A, +5VSB@3A. You want to make certain the +12V will do 28A or more. You can see this example (1000 watt PSU) does 83.3 amps - more than enough.

    Here's a convenient list of video cards, recommended size power supply and amps used:

    You will notice from the list for the GTX 970 you can get away with a 500 watt power supply but I would, personally, still go for 600 watts or greater.
