First time going SLI need advice

McRooster · Jun 18, 2014

Hey guys

I'm thinking about doing some SLI to help run a few of my games at higher settings/FPS
Right now I have a
Asus GeForce GTX780 902M/6008M 3GB GDDR5
http://www.newegg.com/global/au/Product/Product.aspx?Item=N82E16814121769R&cm_re=asus_gtx_780-_-14-121-769R-_-Product

I also only have a 650W power supply. Although I do have a 750W power supply at hand if needed.

Will I need to get the exact same graphics card? Or just a one with the same memory and clock speed?

Hi McRooster
get the same gpu - 780 with 780 , clock speed does not matter , brand does not matter, same memory

you need the same graphics card to work, so get another GTX 780, no matter the difference. You will also need to use your 750W PSU.

mickypheonix :

+1 for this.

About the PSU though, neither 650W nor 750W will be enough for GTX 780 SLI, 850W is the minimum I'd recommend: http://www.realhardtechx.com/index_archivos/Page362.htm

Yeah I can grab a 850W power supply. My CPU is not OC (i7 3770k), although if I did want to OC it and the GPUs (with the manufacturers software settings) what power supply would I need? Perhaps 1000W?

mickypheonix · Jun 18, 2014

i would go 1000 w for headroom especially if overclocking
get a quality psu from seasonic/xfx or corsairs TX,HX or AX range of PSU's or any psu from coolermasters V series or Evga supernova series

McRooster :

1000W would be the sweet spot for a build like that with OC.

unknownofprob · Jun 18, 2014

to be honest 1000W would be overkill, a 850W PSU of a quality nature will perform just as good even for overclocking.

Just get a PSU like the Antec HGC-900, I have this PSU and love it, exceptional for the price.
