Enough juice for the x1900xt?

Is the Antec Truepower II 550W PSU (http://www.newegg.com/Product/Product.asp?Item=N82E16817103931)
adequate enough to run a x1900xt?

I read the x1900xt requires >26A on the 12V rail, however this dual +12V rails are confusing me.

thanks for any feedback.

More about enough juice x1900xt
  1. i dont see why not i got 520 running a sli rig
  2. I believe the dual 12V rails are for SLI? The Antec should definitely cut it, they make some nice power supplies. I don't remember specifically the diff between the neopower and truepower or whatever. Anybody?
  3. If you are running the A8R-MVP with the X1900XT, it has been reported that 26 amps are suggested for stability on this particular setup. But the X1800XT with this board seems to do fine with the Antec TPII 550.
    I hear the A8R32-MVP resolves this with 8-phase power design.

  4. That board is so ridiculously overclockable... 8 phase owns.

  5. Thanks for the replies.

    I decided to go with the enermax liberty 620w. May be a tad overkill right now, but I put together my new rig so I wont have to upgrade for a while (hah im so silly for even saying that) see below.

    I figure once you hit a certain price for a rig...what's another 90 bux on a PSU? oddly enough, i say that for every piece i am putting into it and the $$ just keeps creeping up. =o!


    DELL - UltraSharp 2405FPW
    DFI LANPARTY UT nF4 SLI-DR Expert
    AMD Opteron 165 Denmark
    OCZ 2GB (2 x 1GB) PC 3200 Unbuffered Dual Channel Platinum
    MSI x1900xt 512mb
    Thermaltake Armor series (black)
    ZALMAN 120mm HSF
    WD Raptor 150GB
    Enermax Liberty 620w PSU
    SONY Black IDE DVD Burner 2MB Cache
    Creative Sound Blaster X-Fi XtremeMusic
    Klipsch Promedia 2.1
  6. I'm currently running 1900xtx + 2 sata drives (haven't yet added my Maxtor 250gb to siggie), also DVD-RW and other DVD drive. Though I have not overclocked my rig, i have enough juice with my aerocool 550 (which i paid less then $100 :P) so I believe that Antec should be good enough
