New video card, old problems.

Re: New video card, old problems.

1kw is way overkill for a single 4870, a good 650w should be fine for a 4870. But if you're going to upgrade a PSU, you might want to get a more-than-enough one if you plan to upgrade to multi-GPU systems in the future. But I think 750w would be good enough forever if you stick to single GPUs.

True but If I ever want to upgrade anything I'll never have to worry about the domino effect with my PSU


Plus it has racing stripes >.>



Can't really say no to racing stripes =\

What you do have to worry about, however, is a reduction in input efficiency. Power supplies are most efficient at converting alternating current to direct current at higher power loads, and if you have too much headroom you will not be within that 'sweet-spot' of operating efficiency. It's nothing to lose sleep over, but it might bother some users who are anal about their electric consumption.

But the racing stripes (ohno)

Re: New video card, old problems.

Yes I did make sure I got rid of all old drivers, but now since it sounds like a PSU problem I pulled my new card out and put my 8600 GTS back in and all of a sudden the computer did the same thing, it just magical shut down. Now I think it is a little more serious than the PSU because I have never had any problems with this 8600 and now im screwed cause I really needed to use my computer for work, haha oh well.

Re: New video card, old problems.

Make sure you havent accidentally knocked any of the little power/reset cables loose while installing your new GPU..

If I were you I'd open the pc and just make sure EVERY cable is firmly where it's meant to be. If there is a loose wire it could be causing your PC to shorten out and turn off.

Re: New video card, old problems.

Yeah im almost positive that all the power cords are set in the right spots, im really confused on what to do now cause I dont think that it is the PSU

The highest efficiency is usually at the middle. My Corsair 650w's top efficiency is at 325w, and the Corsair 450w's at 225w. The difference is only about 2 or 3%, and they're both 80 Plus certified.

well, most people here think it is and they have some evidence and what-not, so i would say that this is the problem tbh :/

He's getting the same problem even when he plugs in his old card which was working fine beforehand so I doubt it's the PSU.

Aside from the graphic card did you remove any other components or wires to the computer??

You could check your temperatures using Rivatuner for your graphics card and Speedfan for your processor but like I said before most temperature problems involving the GPU will usually result in a freeze, A cpu heat problem can result in a total shutdown but for that to happen your CPU would have to be hitting temps of 70c+ so maybe just make sure you haven't knocked your CPU's heatsink loose in the process of replacing your GPU.

Prior to this problem did you install any new programs or anything aside from the new GPU drivers?

Re: New video card, old problems.

Yep, if you went back the way you were then it could be an overheat issue. Download the free temp check programs and the ram test and test everything out. Dont look at the computer as a whole, but pieces at a time. You will just get overwhelmed looking at it all.

Also, make sure all your peripherals are seated correctly; RAM, power chords/connectors, PCI cards, fans...

The efficiency curve of a switching power supply unit varies significantly from unit to unit, as well as regionally. If you use 220v, the difference will be much more significant than if you use 110v.

Considering that say, 500 watts, a difference of 3% could be a difference of 25 watts, you could end up with a noticeable difference in your electric bill each year, so 3% is nothing to sneeze at.

And 3% is really a 'best-case-scenario' number. Some units could have a difference of as much as 8%.(Worse case scenario number) At 500 watts, 8% could be a difference of 70 watts.


Since Crazy Eyed Cat has a relatively high quality unit, it's probably not that big of a worry, however, it is something to take into consideration when purchasing your power supply, since in many cases I could end up making a large difference.

tbh isnt 1000watts like major over kill to most people around here

Yeah but most the people around here aren't as awesome as me..

Re: New video card, old problems.

Dont assume all the cables are in correctly, open the case and push each one firmly in to be 135.789986% () sure they are in correctly.

Uninstall all your graphics drivers then install and run a driver sweeper. This is important when switching between ATI and NVidia as the remains of one set of drivers and cause problems for the other.

Check all your cooling fans + heatsinks, make sure they are not clogged up with dust and are still spinning correctly.

Download and run memtest86 to make sure there is nothing wrong with your ram.

Is your hard drive making any unusual noises?

Re: New video card, old problems.

Thank you everyone for your help, what happened is my crappy fan and heatsink on my processor came loose and my processor was overheating and shutting down. I installed a new fan on the processor and it is running like a dream. Now if i could only figure out why the last level on Crysis keeps freezing on me.
