What is SLI?

[steve695]

Hey all.

I am building my first computer soon and I have seen people mention "SLI", what is it?

If it helps I am going to be running an Asus Z68 motherboard with an overclocked i5 2500k and the GPU will most likely be a 670GTX (I want to be able to run BF3 maxed/smoothly).

So what is this SLI business?

 

[steve695]

yes though what series?
the ZT or Fatal1ty?

a quality 550 watt for 1 GTX670 a quality 750 watt to run 2 GTX670 in SLI

what are you willing to bet on that?
NVIDIA GeForce GTX 670 2 GB
single: with a more power hungry sandy-E set up . .

NVIDIA GeForce GTX 670 2 GB then add 162 for another card

for SLI this will work;
KINGWIN Absolute Platinum Series AP-550 550W $119.99
oh, and have a review on that too
Kingwin Absolute Platinum 550 W

I don't fully understand the graph but thanks

Will that PSU work for 2 GPU's and does newegg ship to Australia?

If not it's no biggy, most of the parts on newegg are on ebay for roughly the same price, some are a little more expensive.

:lol:
yours is fine, i was just correcting the, "you need a 750 watt PSU to run SLI" myth . . . usually a 650 is fine.
a 4 x 6+2-pin PCI-E is what is important after the amount of AMPs on the 12 volt rail.

Well you learn something new everyday i guess :lol: still i don't want to trust that though and i would only use 750watt 😉

 

[steve695]

Oh I see, I will stick with the ZT OCZ 750W then 😛

I posted another thread about how I have seen GTX 670 under several brand names and am a bit confused by it, can you please guys help me?

the energy efficiency of power supplies drops significantly at low loads; less than 20%. when you overcompensate due to "comfort level" your actually shortening the life expectancy of the PSU because it sits and get hot when idling, doing nothing.

the very best recommendation is idle at 20% load an max at 80% for what the rig runs. a 750 watt PSU would need not to idle less than 150 watts.

when enabling speed step for the CPU and how GPU manufacturers the same on their card anymore; idle levels are falling so that an i7 with a 670 SLI set up won't hit 125 watts.
