I,m looking in the future to SLi a pair of 460 GTX cards and i,m needing a new Psu so was looking at this one, Sapphire Pure 625W Modular Power Supply. It has 4 x PCie connectors and seems perfect for the job...

just needing confirmation that it would power 2 x 460 gtx cards and also if its any good....

Rest of spec is

X4 955 @ 4ghz
4gb ddr 3 (2x2gb)
3 sata hard drives
Asus M4N98TD EVO
Sata DVD
6 x 120mm fans

Cheers

Hmm just read a review for the XFX and it is very highly rated although it failes to meet its Bronze 80+ rating...

Havent found anything really on the Sapphire but i think i,m going to go with the XFX...

Its a shame OCUK does not stock them...
 
Im amazed and impressed :D

Would love to see how it performs against the i5 @4GHz as all the reviews on the 955 are @ 3.8!

What case do you have aswell ;)

I was quite immpressed too... It needs 1.5v to do it but has never gone above 45.c...

I have a Antec 300 with 4 x120mm fans and 1 x 140mm fan.. Airflow is quite good...:D

Sapphire Pure PSUs are rebranded 'Fire' PSUs, which you can find a couple of reviews of if you look around. They were made with help from Enermax, who're just as good as Seasonic really.
 
I asked a while ago on this forum if there's really any advantage of going for a single or multi rail power supply and didn't get any answer, and I still don't know for sure if I'm completely honest. I think generally it doesn't make a whole lot of difference, however a lot of the high end PSUs tend to be single rail these days so I guess there's a good reason for that.

However if you'd really notice any difference between running the system on the 2 PSUs is another question...
 
The truth regarding the choice between split rails or a single rail is that it's six of one and half a dozen of the other as long as the psu is well made by a reputable company, it will work fine regardless of the number of rails.

If you want to read more about it there is an article here:
http://www.maximumpc.com/article/single_rail_versus_multi_rail_power_supplies

Tl;dr version:
If you have a single monster rail it can feed components exactly the power they need, but it is not in accordance with the EPS12V standard which says that a 12V rail can not exceed 20A

Multiple smaller rails on the other hand can get a little complicated when wiring your cpu and graphics card(s)

Its more of a want than a need.. tbh :D

It will be a few months before i get the second card, Just need a Psu now so want one that will be up to the job when i add the second card.

Getting a second card is a complete waste of money at that resolution.

More powerful single card > dual cards.

Maybe the OP already has a single GTX 460?

Correct i have a 460 gtx... Adding another later down the line will give me a nice boost without having to splash out on a more expensive single card..

I have read that Sli 460 gtx,s gives better performance than a single 480 gtx in games that support it..
