Morning guys,

I hope one of you can help me w/ the varying statements given on my required watts. I just ordered a second Ichill 760 after being v happy with the first one I bought together with the rest of my new rig 3/4 year ago.
Unfortunately, I didn't think too soon about adding another sli card and thusly only bought the 580W be quiet! straight power. So far it worked perfectly, but I doubt that it runs as fine with a second relatively strong gpu.

What do you guys suggest? The rig would be final so far, only minimum OC is being done (MSI Afterburner on the GPU's, that's basically it)

MSI G45 Gaming
i5 4670K + Shadow Rock 2 CPU cooler
8gig ddr3
1x 120g SSD / 1x 2TB SSHD / 1x 3TB HD
1x DVD/CD RW Combo/ BR RoM
and now 2x Ichill GTX 760 (Sli)

Asus PSU calc throws me 950watts in my face which seems a bit over the top imho, the other calculator on the be quiet! homepage ends up at around 650W.

What do you guys say? Thanks in advance for your estimate!
Nico :)
 
Solution
650W should be enough but I would buy 750W coz I don't like my PSU working on >70% all the time :)

there's non modular xfx 750w for 70$ if you don't mind non modular :D

Based on the above info, max power consumption will be 340W only for the two cards in PSU.
Not sure about it being enough or not, but it would cut it too close for my linking...

Thanks guys for your quick replies :)

Been taking care of a low noise rig, the cable management wouldn't be a big deal since it's always covered anyway. Concerning the noise lvl, would you still suggest the xfx (before I look into any reviews). Been playing with simply upgrading to the be quiet 680w in my head if that would cut it :)

Great, thank you Proofy :) After doing some research and compare it with the XFX XTR Series 750W, I decided to stay loyal to be qiet! after its superb performance so far and get the PowerZone 750W.

Thanks again and have a great day :)
