- This is my system info from outervision power supply calc using (1 x GTX 260)

Quote:
System Type: 1 physical CPU
Motherboard: High End - Desktop
CPU: Intel Core i7-930 2800 MHz Bloomfield
CPU Utilization (TDP): 90% TDP
RAM: 3 Sticks DDR3 SDRAM
Video Card: NVIDIA GeForce GTX 260 Core 216
Video Type: Single Card
High rpm SATA: 3 HDDs
DVD/CDRW Combo Drive: 1 Drive
Sound Blaster - All Models: Yes
USB: 6 Devices
Fans (Regular): 1 Fan 80mm; 7 Fans 120mm;
Keyboard and mouse: Yes
System Load: 90 %
Recommended Wattage: *486 Watts


- If I add another GTX 260 it brings my total to 581 Watts, which is much lower compared to NeweggsPScalculcator(876 watts). Hopefully outervision's is more accurate.

This is my power supply..
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
620 watt (+3.3@24A,+5V@30A,+12V1@18A,+12V2@18A,+12V3@18A,- 12V@0.8A,+5VSB@3A)

*** I will not be doing any overclocking. EVERYTHING in the machine will remain stock.


Can I run this SLI and still have a safe and stable PC?


Thanks in advance for any help,

That is a quality PSU that should handle it fine!

I would say so, yes. A 620W Corsair PSU is way more stable than a 1000W off brand PSU.

I'm running 2 260s, two HDDs, 6 sticks of ram, and I have my CPU oc'ed to 3.7 GHz, and I'm using Corsaris 750W.

That PSU says it can handle 50 amps on the +12v rail and Corsairs rating can be trusted so it should be fine for SLIed GTX 260s

Great news. Thanks for info guys.

I originally bought it to have the option for SLI (before I upgraded to the gtx260) and I just upgraded everything else in my PC except for the PS and VC. It's good to know it can handle the increased load. :) 


Thanks again, :hello:

Actually it would be a better idea imo to ebay your current GTX 260 and put that money towards an HD5850 or GTX 470. Once OCed you will get similar or better performance as well as DX11 and no SLI scaling/compatibility issues. The cost may even be less.
