hey i know this definitely sounds noobish. i'm looking for a poweruspply with a min of 350w and a 12v @ 18a. soo i was wondering with the new atx12v that it has 2 12v rails. does that mean that the 12v amperage is the total of the two but they're split up? i know that a regular atx one would work but i would def like to find a newew atx12v one. my video card needs the 12v @ 18a. does that mean the atx12v would work even though they're split up?
sorry lol i'm upgrading to a evga 7800gs agp and got a dell dimension 4600 with a 2.4ghz processor. 4 sticks for 1.5gb of ram and a dvd burner and a cd burner and 2 hard drives. the stock power supply for the dell i was told was 250w and it was like 16a on the 12v from what i read on the lable of it.
However, I am not sure if Dell PCs, well Dell mainboards, will work with a standard PSU (Power Supply Unit) or not. Dell have done weird things in the past so only Dell PSUs will work on their systems, to limit upgradability.
Personally I'd lean towards selling the mainboard and replacing it with a PCIe model, then getting a PCIe video card with 24 pipelines (vs 16)... but that is just my preference. Yours may differ.
As far as pinout of the PSUs, Dell stopped propietary wiring on their mobos around 2001. The issue should be whether or not the PSU will physically fit and location of switch/plug. The best way to determine compatibility is to look at the layout of both.
