Alright well that card dosemt use any extra power. It relies solely on the PCI express for power. So that would be 12v and 65w I'm looking for.
ow what about amps? How many amps does a PCI push out?

Any of your listed cards will work, if you don't want one with an auxiliary power connector choose accordingly. The PCIe slot wil supply power based on the load that is on it and will vary. The wiki article shows maximums I think.

for the cards, im just asking which brand is best out of the list. i know they will all work lol

so i found this PSU:

Amazon.com: Replacement LCD 60W 12V 5A adapter charger for Benq LCD Monitors:FP2081,FP450,FP547,FP553,FP557,FP563,FP567,FP581,FP581,FP591,FP731: Computers & Accessories

its the closest i found to 12v 5.5a and 65w. but cant i get a PSU with 12v 5a and like 75w? or will that burn the adapter and card up?

Alright i decided on the sapphire card. its cheaper, faster memory clock speed, and got better reviews.

I had no brand preference out of your list, I like EVGA and ASUS though.
I just watched the video (of a very disorganized person) about what you are trying to do. I reckon you can use the laptop charger or monitor power brick since he used a similar one. He made a huge mistake about the PSU though, you'd want to jumper the green and a black wire, not orange, that would fry the PSU.

That's depends on PSUs I believe. When I tried to get one to power an car amp and sub, the wires were all different on that. and people where saying different color wires.

But cant I get a like 75w one so that way I have room for card upgrading or will that fry the card because is straight power through it? I've read that a PCI pushes 75w through a normal PSU.

That rating is the maximum it is capable of comfortably delivering not what it will "force" out, the card will draw as little or as much as it requires so anything over 65w should be compatible, i personally would go over for future changes and so you are not running supply at 100% capacity which will generally cause it to degrade and fail quicker, i would aim for a unit that will run at maximum around 80-85% of it rated capacity

max PSU ive seen of that type is 12v 6A 75w. ill look for something esle, but since PCI requires 5.5A, would it be better to get a 5A or 6A psu?

edit:

so ive been searching, and ive found 2 options

1) 12v 5A 60W
2) 12v 6A 72W

so question is now, would it be better to go with the higher amperage or lower amperage. its only .5A difference.
