[Solved] Can't provide power to GTX650ti

I just recently got a GeForce GTX650ti 2gb and I can't seem to provide any extra power to it. I have an HP Pavilion p-2120 and there aren't any 6-pins to plug into the gpu; there doesn't seem to be anywhere to plug in the molex cables on my molex 6-pin either. This seems to be the only problem. The card is installed fine and the fan runs, but it doesn't show up in my display adapters and when I connect my VGA cable to the card the screen won't appear. I think the problem is the power supply to the gpu but I'm not positive.

  1. Yes you need to get new psu.dude unplug that card.running that gpu without 6 pin connector is not reccommended.
  2. Thank you for the concern, but I don't have the card plugged in. Also, what kind of power supply would you recommend I get?
  3. Please tell your whole specs.
  4. Always one of the things you find LSD with pre built systems, only ever made to the specs of the built system, with little option for upgrades, a weak small Psu with the lowest power rating to run the current hardware fitted.
    I hate to insult you but this why people build there own systems and choose the Hardware to build a Pc. Pre built systems always have a lack of thought put into them, and limitation because they simply expect you to ditch it after a few years and by a whole new system from them.

    They do it on purpose.

    In any case now you will have to buy a more modern Psu with a better wattage rating and a higher Amp rating on the Psu on the 12v rails to get everything working right, plus due to the design of the case and its dimensional specs it may cause problems in fitting a new psu into the case. As well as buying the card you now have to buy a new Psu. so the cost mounts. One of the main reasons why people prefer to build there own systems is because they want to make sure when it comes along there will be no problem like this, knowing it will cope with the next upgrade or part they choose to fit. Spending less money for example having to buy a new PSU and a graphics card to get it to work right.
  5. Bear with me, I'm not very good at finding specs but is this enough.

  7. Do you hold that as your best solution or is there anything else?
  8. No other solution.for gtx 650 ti you need good power supply.
  9. Specs are fine LSD, its just the PSU as said that is letting you down.
    Here are the specs on the graphics card you bought, its power draw in watts at full load when playing a game ect, and the amp rating it also requires from a 12v power rail for it to run stable without crashing the card or the rest of the system.

    You will need a Psu of 500w minimum that can provide 31A or more on the 12v rails of the Psu. So have a good check on the specs of the Psu, Good known brands to buy are ocz, Silver stone, corsair. Try to sick with these I know they may be expensive.
    But cheaper unbranded Psu supplys for $40 or less more than often dont live up to the specs they state on the information sticker of its output in amps or wattage. And also have less safety features such as overload protection, and other features. In the long run it pays to buy a quality well branded Psu for peace of mind LSD.
