VGA quesiton

Hello,
I've an HP mini tower convertible...with a 350 hp Power supply, my motheboard is a Intel Q45/Q43 and my VGA is an ATI HD 4650which means no 6pin i was wondering if i could upgrade that VGA for a 7750hd which is the same power consumption but better and doesnt require 6 pin

  1. Not without a new PSU as they recommend a 400w PSU minimum.
  2. should work fine as it only drawing 75 watts from pcie slot not requiring any extra power connectors.
  3. But the ati HD 4650 also requires a 400w PSU oh if it helps i got an Intel core 2 duo E8400@ 3.00 Ghz
  4. Could you not buy a new PSU and GPU. I wouldn't be comfortable running a system like that.

    It will probably work if the old one works but I wouldn't count on it being stable.
  5. I actually bought a 500w thelmatake but that Motherboard doesnt take it... as it a HP pc not a clone :S
  6. Well that 7750 doesnt draw more than 50W from your system.So you would be ok as soon as that PSU delivers that power.

    But as u runnign a 27W GPU 13 W more will beok.

    I say go with that upgrade.
  7. I also got a 6850HD but yeah....it was a failure...i just bought it without checkin my pc spec

    Thnks for the replies btw...u guys are awsome

    That 6850 consumes 130 W so sure it was a failure :D

    But that 7750 wont be !
  9. If it isnt 2 much i am also planin on buildin a rig n few month, i got the 500w psu and the 685hd, which MotherB should i get? price range uhm 100~250 bucks
  10. Well what PSU it is. I need more info not just thermaltalke.

    And you would need a new cpu. So total budget for

    Ram , CPU ,Mobo is ?

    I assume u will use your old HDD .

    So u have a Hd 6850 / 500 W Psu / Hdd.
  11. I can spend aroud 400~800, @ Thermaltake is a TR2 500w
  12. Well u need a new PSU than. That is a crappy PSU that failed to deliver its Wattage.

    So let me build 1 :)

  14. Awsome, thanks alot Prototype18, you rock :D
  15. Your wellcome !
  16. Uhm its actually a 320w power supply, should i still go wth the 7750HD?, oh my ram seems to be runnin at 600mhz ( which its pretty sucky ) if that helps
  17. Hmm im not sure. Can u give specs of the PSU . Read the sticker and tell us the amps and wattage on 12 V rail/rail's.

    But better get a new PC :D
  18. Ok let me check it out but its an hp 1, it says 12.1+Vmain & 12.1Vcpu Shall not exceed 320w model: HP -D3201A0
    100-240v-/5.5A, 50~60hz
    +12Vsb=====/ 1.3A -12V=====/ 0.15A

    Oh my ATI HD 4650 is the 1gb version DDR3 ( if that helps )
  19. Wtf 1.3 Amp . U sure ?

    Well better get that VP 450 for 30 $
  20. So will it be a failure? how come it runs the 4650HD, thats like my main question...if u want i can take a picture of it
  21. Yes better post a pic.

    Well that 4650 consumes less power than 7750.

    Just 27 w
  22. But i saw on a website it said both consume 55W, i am get the pic i a moment

    Pictures are a bit blurry, sry Prototype...in anycase is here any card that i can use ? to upgrade tht 4650hd?
  24. Are there 4 12V rail ?

    13/15/16/14 Amps each ?

    If so that 7750 will work.
  25. How can i tell that? sorry for all these questions i just sooo noob at pc building...i bet i am giving you a headache :S

  26. Best answer
    For a system using a single Radeon HD 7750 graphics card AMD specifies a minimum of a 400 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 19 Amps or greater.

    Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important factor.

    So your system have total 320W but it can deliver it all on the 12 V rail. So assume 290/12=24 Amps.

    So to end it 50/12=4.1 Amp to run that card.

    You are safe :D
  27. Lol i am learning all this stuff with you, thank you for your patience
    1 last question....and seriously ur just amazing
    Higher frecuency and DDR @ Ram requires more watts?
  28. Best answer selected by tripeatex.
  29. Hmm Ddr3 ram stick requires 8W. And the Ddr2 2W per stick.

    Glad im helping you :)
