Hi,

I have a quick question, i would like to know if this current build will run fine if i go sli with gtx260 core 216 using my current PSU?

CPU: Intel E8200 (Stock)
Mobo: Asus P5N-D
Graphics (current): 1x GTX260 core 216 (Stock)
RAM: Kingston 4gb 800
HDD: 2x 500gb Hdds
PSU: Xigmatek 650w (http://www.xigmatek.com/product/power-nrpmc651.php)

I won't be overclocking.

I tried looking around and i couldn't find a straight answer. Some ppl say yes and others say no. I am a noob when it comes to PSU's and power requirements.

Any help will be much appreciated,

Thanks!

EDIT: My PSU has 3x 6 pin connectors and 1 of the 8 pin connecotrs can convert into a 6 pin making 4x 6pin in total. each 12v rails are independant and have 18amp ratings.... is that enough?

Your PSU should be plenty
the wost case, you wait to buy one, and test for instability.
But i don't see how your setup, even OCed will max out your PSU. I'm not really familiar w/ the brand but you should be good.

You should change your PSU. The GTX260 SLI takes in 610W on load. That leaves absolutely nothing for other components. Plus there's the question of reliability.

This review shows that its certainly not the best one available in the market.
I would suggest Corsair TX750 for you or TX850. Whichever fits your budget!

Where do you see just the video cards taking 610W? The only 2 video cards i see taking that much power are the 5870 in CF.

I am personally running 2x 9800GTX in SLI with a Pentium E6500 at 3.66ghz and 5 HDDs, all on a OCZ 500w PSU. So no, you dont need any more PSU.
