X1900xt question

The power supply should have the cable. Check.

The card should also come with an adapter, Molex 4-pin --> 6 pin PCI-E.

You can pick up an MSI X1900XTX for around $284 after MIR. Newegg, and zipzoomfly is currently out-of-stock but you have until the end of the month to buy one. There are a bunch of qualifying stores so you can check to see if one of the other stores have one available. Otherwise, if you can wait and see what happens, this is a better deal. MSI X1900XTX

Yeah it has one but for more stability you should use a PSU with dedicated 12v video card cable.

It comes with a 6-pin to a dual 4-pin power connecter. Unless it is OEM, then you're SOL  

Don't listen to this, an Antec 480w will handle an X1900XT perfectly.

Ok so i checked before and could not find the dedicated PCI express power cable...but then i just checked again and found it hideing behind my mother board.  

Now for all the cards im looking at, they recomend 30 amps on a 12 volt rail. When i look at my power supply i see that it has listed as output + 12 V1 and + 12 V2. these are both rated as max output at 18A. Then it says below that 12V1 and 12V2 have a max load of 33A.

If i understand it right the power supply should be able to handle the new card. Anyone know otherwise?

If the PSU shows a +12v max load of 33A then it will be fine. Presumably it is using the rails together to allow greater current for heavy load.

Comparatively my Antec NeoHE 550w only offers 18A on each of the three +12v rails individually, but it is SLI certified.
