The recommend a PS with 400W and 20A on 12v. They are not talking about
a single 12v rail with 20 A, just 20 A on 12 V [read it again]. Also,
they are not saying that their card will use all of the 20 A on the 12
v, since other stuff may be drawing current on 12V. They just recommend
that because that's what a typical PC will need (with some overhead) if
their card is in there.
Probably it will work as long as you don't have too much other stuff
drawing current on the 12V line.
According to Maximum PC, most PS don't really supply separate "rails"
anyhow. It's all connected to the same point.

Greetings,
I have a XFX 7950gt 512M AGP and Nvidia recommends a 400W power supply
with 12v=20amp.
I have a Thermaltake 550W dual rail (12v1=14, 12v2=15). Will it be good
enough to run my video card?
Could someone explain how this works?
My two 12v rails are
12v1=14amps
12v2=15amps
The card wants 20 amps and these two are below that.
Do I add them together to get 29 amps which is more than enough?
Regards,
Jason
