Question about 6600 GT/PSU Compatability

I have a MSI Geforce 6600 GT coming and have recently read some things that have me a little worried about compatability. The specs at the manufacturers site say it requires a 300 watt PSU. Mine is only a 305 watt max. PSU and I have read that some systems with a 350 watt PSU even have problems running this card.

I meet all the other requirements by a long shot, but Sony just had to put a crappy 305 watt PSU in this machine.

Please help!

  1. What are the rest of your specs? I had to get a new PSU for mine, 350W didn't cut it :x
  2. My specs are:

    3.2 GHz P4
    1.5 GB RAM
    250 GB HDD
    Pioneer DVD-RW

    I'm not really sure about the motherboard, since I didn't build this computer. It's a Vaio RB-50 and has 2 PCI slots, 1 PCI-e x1, 1 PCI-e x16.
    I have 3 fans total (1 in the PSU, 1 on the CPU, and 1 case fan).

    I'm a newbie, so if these specs aren't what you were looking for, I give you my apologies.

    Thanks for your help.
  3. Those are the specs! There's a thread around here somewhere with a link to a PSU calculator but I'd wager you're probably going to be close the 300 with a 6600GT.

    You won't damage your system by throwing the card in though and giving it a spin. So I say toss it in there and fire up a game! If it crashes right away or after a while your PSU can't cut it!
  4. Thanks, FlyGuy. I've been researching on my computer for pretty much the whole evening and have found that 18A on the +12V (which is what I have [whatever the heck it means, I don't know]) should be fine to run this card. Hopefully I will get the card tomorrow, plug it in and not blow anything up (except for other players in Halo).

    Thanks again for your help.

    You're welcome, go frag some biotches!
  7. since before your sun burned hot in the sky. i have awaited a question.

    my specs will guide your ass:

    p4 prescott 2.8 oc to 3.08
    1 gig pc3200
    6800 gs

    power supply 300 watt 12v/18A
  8. JJ_Mclure,

    I'm not sure I follow your interesting Chinese proverb, but my specs are fairly close to yours (3.2 P4, 1.5 GB RAM[2x256, 2x512], 305W with +12V at 18A). Do you have any problems with your PSU running the 6800 gs?
  9. I have a thermaltake 420 watt PSU. It has 18AMPS on the 12V. My 6600GT is overclocked 550 Core and 1.15GHz mem. My comptuer is in a little cubby hole here in my desk, and i noticed if i have the door shut while playing a game for a while the compter will freeze, or the monitor will go dead. A clear sign of the PSU not supplying the video card with enough power, or the video card over heating. (what do you guys think it is?)
  10. I think it's heat cuz I have a 430W Thermaltake and an EVGA 6600GT @ 550/1050.
  11. I have the Enermax Liberty (400W) and no probs here (also 500/1100 clocks).
  12. no timbob,

    i have never had a crash or freeze up with batt 2.
    i even bought an antec 400 watt to test it out and my 3dmark scores are all the same. so i am taking it back.


    i assume that is the test. i wonder if an underpowered PS will make the card run slower?

    anyone wise men or women answer dee question?

    Don't know about wise but experience I have. I had a 350W Enermax and the games would run fine for 10-30 minutes and then either freeze or crash, usually crash. Upgraded to 430W Thermaltake and it took away the problems.

    Dude, can you say OVEN!!!! You're cooking silicon. Leave the door open and your system won't suffocate and burn up at the same time.
