First time building, suggestions wanted.

Hi, thanks in advance for any help.

I recently purchased 2 Gainward GTX 460 2GB to replace my old 9500GTs and a 1000W power supply to feed them. However, after installing them the machine would cut power after a few minutes of being turned on. I assume it is the mobo that is causing this problem.

Would it be possible to salvage my cpu and avoid having to completely upgrade my PC to support the GTX 460s?

My current machine:

CPU: Intel Core 2 Quad Q9550 @ 2.83Ghz
MB: Asus P5N-E SLI
Case: Unknown
GPU: Nvidia 9500GT x2 (SLI)
PSU: 350V, unknown make
Memory: Corsair Value Select 8GB (4 x 2GB) 240-Pin DDR2
HDD: 750 GB Seagate Barracuda

What I intend to build:

CPU: Intel CPU i7 870 Quad Core Processor

Would this be ok, or should I use different parts/ more parts?

  1. The problem has more than one aspect IMO

    1. Your mobo
    http://www.newegg.com/Product/Product.aspx?Item=N82E16813131142
    650i chipset is 8/8 on PCIex16 gen 1.0/1.1 and there would be between a big to huge performance hit when SLIing current GPUs

    Here was data relevent: multi GPU (CF in this case) pciex16 gen 1.0/1.1 vs gen 2.0
    Study the P35 vs X48 column


    2. Connectivity check with PSU? Is the 6/8 pin PCIe connected via PSU to GPU? State model/make of PSU
  2. icute is not known for their quality more the lack there of get this instead

    more then enough for sli 460 or even 470's

    get this if you want to sli 480's

  3. Whoops didn't catch that PSU model lol Ya get something like what obsidian86 suggested - hands down more dependable than an ICute!
  4. Your CPU is very good, wait a little for the new ATI 6 series and get a single more powerful video card (and a PSU). If you get a single card you can get away with 650W.
