Can this PSU run SLI good?

post #1 of 7
Thread Starter 
I got a Xion PowerReal 600Watt PSU. It was 99$ and I have to say it runs pretty awesome. No problems so far, but if I ever wanted to SLI would it be able to? For EVGA GeForce 7900GT KO

http://www.newegg.com/Product/Produc...82E16817190007

It doesn't say SLI ready or anything so I have no idea.

Was this a good choice for the price also? There was a 40$ rebate.

Probably...

The 7900GT cards aren't that power hungry, but before anyone can say for sure you need to find out the ratings for the 12v rails mainly.

Look on the side of the actual PSU it'll have a table with the ratings on. Hopefully something like 12v1 = 18a, 12v2 = 18a along with 3.3v and 5v ratings.

They're what we need to say for sure.


Here's what the SLI website says:

Easily... aslong as the rails dont fluctuate, which you can monitor from cpuz and speedfan along with other programs... it should have more than enough power to run almost any SLI with.

Follow up...(Leaving the post before as it's good info)

Newegg posts the rails as "+12V1@22A, +12V2@22A," which is fine for 7900GT SLI. Although, I wouldn't trust that PSU for significant CPU+GPU overclocks or any more expensive hardware...not a brand I've heard of before.

Assuming you want it for that Ultra D...

it is not in the DFI recommended PSU list. And those guys really put their PSUs to the test. I would not trust it for SLI setup.

Obviously a DFI certified, SLI certified etc certified PSU would be best, but the OP's PSU is definitely capable, just not of the best quality - i'm sure they know this, you don't buy a $60 PSU and expect the world from it.

It works great for overclocking my GPU and CPU. I can mod the Ultra-D to SLI when and if I decide to. I never heard of the brand either but it had great reviews.
