PSU or graphics card?

I have an HP p6214y and I upgraded from the integrated graphics card geforce 9100 to powercolor hd 4850 512mb
But I also had to replace the PSU so I got this:

http://www.newegg.com/product/product.aspx?Item=N82E16817822002

When I play games like Crysis warhead or Modern warfare 2(any other game as well), my system starts freezing up about 10 minutes into it. The computer screen freezes for 5 seconds and then it goes to sleep even though my computer is still turned on.
I am sometimes seeing artifacts and the game quits and the little bubble at the bottom right of screen says ATI driver has successfully recovered.
I have the latest updates and driver.
No virus and computer running at optimal
WHAT DO I DO????!!

Temperature at idle: 42
Temperature after gaming for 15 minutes: 53

Minimum requirement for graphics card is 450w.

  1. Get a new PSU, the minimum for a 4850 is 30amps on the 12V rail, you have 24.

    This will be great:

    Thanks for quick reply.
    Is there any other PSU that's a bit cheaper?
    I'm on kind of a budget right now & as student $55 is a lot.
    Will this even fit?
    My current PSU is 4.8" x 3.8" x 2.5" and it fits right into the case. The one you suggested is 5.9" x 3.4" x 6.5".

    And +12V1@18A,+12V2@18A is better than +12V@24A?
    These things are very confusing...
  3. Power issue! That is definitely not a good PSU!
  4. Wow that PSU has some crappy specs, 24A on the 12V rail? The corsair 400CX has 30A, im definitely betting on the PSU, its probably not providing stable power at that level of draw, the PSU calculator recommends about 280W using a 95W CPU, and consider that 80% of a modern systems power comes from the 12V rail and i didnt even select worst case scenario, if you have a 125W CPU you are almost certainly over the power it can stably provide which would explain your artifacting.

    Get a GOOD 500-550W PSU, try to get one from Seasonic, PC Power & Cooling, Antec, OCZ, or Corsair. There are other manufacturers with good units out there so if those manufacturers are out of your price range there are other options, just make sure to remember that wattage doesnt mean a thing and look at the combined amperage on the 12V rails, if its got multiple rails and it doesnt tell you the max combined power skip it and move on.

    If your budget is $55 I would get one of the following:

    OCZ StealthXStream 550W $35
    BFG Tech GS-550 550W $50
    ThermalTake PurePower 500W $55
    Antec Basiq 500W $45

    But like I said your issue might be unrelated to the PSU, but certainly if you are running HPs standard PSU you need a new PSU anyways for a dedicated video card such as a 4850.


    Im running a diablotek phd450 which i got for 30+shipping on newegg.
  6. I did a little research and found that it might not even be the power supply unit, but rather dust clogging the fan of the GPU. I'll check it out and get back

    Either way you have a poor quality PSU.

    As hunter mentioned above, one of the least expensive quality PSU's that could handle a 4850 is the Corsair 400cx. Its $39 after MIR on newegg.

    I own it and its great--It has 30A on the 12v rail, it is almost perfectly silent, sucks air across my cpu and it blows cool air out of my case. It is also more than 82% efficient--while your PSU is labeled as "up to 78%"

    Ok, I will go with this one:

    As BDDazza suggested, will that solve the issue of poor-quality PSU?

    In comparison to your current PSU its much better, for the price you can not complain either :)


    Ahhh, installing new PSU didn't solve the problem. I'm going to send the GPU back for repair or replacement.

    How much did you pay for the 4850 BTW?

    To be honest, I didnt think it was a PSU issue, sure your old PSU sucked but I was positive that it was a hardware defect with the video card or a driver related issue.

    I think you'd be better off asking the retailer for a completely different card or atleast the same card from a different brand.


    I bought it for 65 dollars plus shipping, which is an amazing deal even for an open box item :bounce: (or at least that's what I thought). Anyways, I issued RMA a couple days ago from powercolor and they sent me an e-mail saying I can ship it to them....apparently I have to pay for the shipping which kinda sucks because I didn't really expect to receive a defected item.
