Powersupply + Video card

[fretboard]

Hey everyone

I'm new to the forum...looks like a great place to help me with this problem I have.


I have a Dell Dimension Desktop 4700; it came with a 3ghz HT processer, 512mb dual channel memory, and an ati radeon x300.

i've since upgraded to 4x512mb sticks and to upgrade to a Saphire Radeon X800
(http://www.newegg.com/Product/Product.asp?item=N82E16814102466)

On one of the comments a customer says: " This is just to prevent anyone else from making my mistake. This is a great card, but it's powered and per ATI's tech site requires at LEAST 22 Amps on the 12 volt Rail. I bought a Powmax PSU rated ...
at 450W and thought it would be good enough, but it only delivered 17A on the 12V rail. I have since bought a CoolMax 550W PSU that delivers 35A onthe 12V rail and have not had a single problem since. Hope this helps at least someone out."

Can my power supply support this card? (305 watts)

heres the info on the power supply:

i don't know if this is right...but i think my 12 volt rail is dual connected.. so i think that means i have 36A on that rail according to my manual? can anyone confirm this?

dual 12v rails goes toward a combined output for overall 12v so if the two rails combine to be what you need then you should be fine, I don't know if that is what you were asking but good luck anyway.

meh.. it says the +12A VDC max current is 18, and the +12B VDC max current is 18.

do you know if the combined amount is 18 or 36?
