How do I know if my video card is 1.5 or 3.3V?

So I FINALLY got my new motherbaord and CPU (I was waiting for sooo long caues FedEx is dumb.) And there is a notice in the mobo manual that I can ONLY ise 1.5 V video cards. I also ordered a new video card, and I can seem to find out if it is 1.5V. I never say a manual for the vid. card in the box.

My video card is an Apollo nvidia GeForce FX 5900XT, 128MB DDR, 128-bit, 8x AGP.

I’ve looked online, but none of the sites seem to indicate that.

Its 1.5 V. All newer Nvidia cards are.

Well hooray!
Too bad I can’t make use of my new system till sunday night (it’s all at my apartment but I am at my parent’s for the holiday.)
