SLI 9600GT, Enough Power?

post #1 of 25
Thread Starter 
I have a Antec Earthwatts 430watt PSU with 2 12V+ rails with 17A on both.

I'm wondering if this is enough to safely run 2 9600GT's in SLI.

I've looked around and can't really get a positive answer, so any help will be rewarded.

Ehm....yeah



The power req for one 9600GT says you need about 400 watts with at least 18a on 12v rail.

I think you need to invest in a beefier PSU for that kind of SLI setup.

edit: Even though you could use the converter plug things, I reccomend that you don't. It's always a safer bet to put it on the dedicated plug.

Also, like I said, you need a better PSU to SLI that. At least 500watt

Aww, it looks like i barley missed the mark. 2 18A = 36A

2 17A = 34A

Well, $140 isnt exactly cheap

I've been building my computer on allowances and birthday money, so i'm really on a tight budget, my 2 9600's will already cost me $240.

Guess it's time to get a job...

EDIT: i could always get Antec Earthwatts 500 watt, it has 2 PCI-E cables, but still 2 12V rails with 17A on them...

EDIT2: I found this on microcenters website "400 Watt Power Supply (with 26A on the +12V Rail); SLI Mode: 450 Watt Power Supply (with 28A on the +12V Rail)"

Now i'm confused

even an overclocked MSI 9600GT1GB @ 800MHz uses about 120 watts......so you could try using molex.....the worst thing that could happen is your comp might freeze up

Either that, or the PSU blows

I think i'll end up buying them, and testing them either way on this PSU... It seems like i would be pushing it though.
