Hi,guys
I'm planning to buy a PSU which is AX860i,and here are my following specs

i7 3770k 3.5ghz
GTX Titan
MSI Z77 Mpower LGA 1155
32g Corsair vengeance 1866
H100i extreme CPU cooler
Lite on 12x Internal Sata BD Writer
Western Digital 1TB Black
Samsung 840 pro 256g
Xonar STX
Logitech Z623
Case: thermaltake level 10 gt

Note that I know that I went completely overkill in some cases.

I really wanted to know that if the AX860i will hold this rig,is there any chance if I can put another GTX Titan in the future?

For a system using a single GeForce GTX TITAN graphics card NVIDIA specifies a minimum of a 600 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 38 Amps or greater and that has at least one 6-pin and one 8-pin PCI Express supplementary power connectors.

For a system using two GeForce GTX TITAN graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 850 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 60 Amps or greater and that has at least two 6-pin and two 8-pin PCI Express supplementary power connectors...
I believe you can run a Titan with a good 550W PSU, so 860W is more than enough. I don't think a second Titan should be a problem.

Just curious though: why the Titan? It doesn't have a good cost/performance ratio.
 
Yes, you will have no problem running your rig on that power supply, I think total you only need around 650W. I would not run a second Titan on that power supply though, it cuts it a little close and I would prefer to have a bit more over head than that.
 


Your kidding right?! LOL I use 2 HD 7950s on a 650W PSU... What do you say to that?
 

Yah,I definitely lose on the cost ,but I just really like a high end graphics card rather than two way midrange cards
funny its been 7 years since I first have my pc,never upgraded ever since.
 


I agree with you. One single powerful GPU is much better for me too, no matter what people say. LOL
 


I'm curious that how many percent will I improve the performance of 2way sli gtx titan over one gtx titan,because the power of the gpu doesnt just double the voltage. I'm kinda newbees though hehe
 


That depends on the game and how it scales, realisticly you can expect a 40-50% improvement in games that are optimized for SLI. But yeah, this will be on a multimonitor extreme resolution setup, not on a single monitor.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most important factor.

Overclocking of the CPU and/or GPU(s) will require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

The Corsair AXi Digital 860 Watt (SKU# 75-001303 / CP-9020037), with its maximum combined +12 Volt continuous current rating of 71.6 Amps and with six (6+2)-pin PCI Express supplementary power connectors, is way more than sufficient to power your system configuration with a single GeForce GTX TITAN graphics card. It is also more than sufficient to power your system configuration with two GeForce GTX TITAN graphics cards in 2-way SLI mode.

@ko888 - Thanks. I tend to say things that I know are true but do not corroborate it all the time. Thanks for confirming.

Can I get the link to those benchies? Would like to see what games to use. 50% is damn good with triple monitor setup but the 29$ for single monitor is not too bad either.

Thanks. :wahoo:
