I have just purchased an ATI X1900 XTX. Upon opening up my PC I have discovered that my PSU is rated for 350W. The specifications for my new video card from the ATI website are as follows: "450-Watt power supply or greater, 30 Amps on 12 volt rail recommended (assumes fully loaded system)" "Power supply must support 6-pin PCI Express® connector (CrossFire™ requires 2 x 6 pin PCI Express connector)". Now normally I would have spent some time researching the specifics of the card. But when you are saving up for an ATI X850 and then suddenly you see an ATI X1900 XTX for about $250 on eBay, you have to jump for it . I am using the PSU that came with my Dell Dimension 9100 right now. Can anyone please recommend a good PSU for me? I cannot find anything with "30 Amps on 12 volt rail". Here are my current system specs (including my current graphics card): Pentium D 2.8Ghz 2x 512MB DIMM RAM (@ 533Mhz) Multi-Media Card Reader DVD/CD RW Drive 250GB Hard Drive (7200RPM) Floppy Drive ATI Radeon X600 (256MB) Audigy 2 ZS Sound Card I have included some unimportant (imo anyway) specifications to let you know about how many connections the PSU will need. On a side note, the PSU I have right now makes almost no noise. I don't know much about PSUs, its not listed in device manager (which is obvious, i've been told), and I can't tell from looking at it what model it is. Sitting here typing this, I can almost not hear it. I have to put my ear close to it to hear it. If anyone knows the dB for the default PSU that comes with a Dell Dimension 9100, please let me know. If anyone can give me any information I would be extremely gratefull. I really would like to play with this new card before my finals start next week (no not this coming week, the week after that). Thanks for your time.
