help choosing a gtx 770 for two way sli

post #1 of 7
Thread Starter 
so i have decided to go 770 sli instead of getting one 780 as i would only be able to afford one 780 if i went that way when i could buy two 770's

so here is my problem. i was going to buy the msi twin frozr gamer series 770 when i found out that it needs two 8pins for a total of 4 8pins which my power supply doesn't have. so what would be another good card that has nice cooling that can be easily overclocked or still perform the best in its class without being overclocked. i was thinking the asus or the evga acx 770. i would be able to have these as they only need one 6 pin and one 8pin for a total of 2 8pins and 2 6pins. thanks for the helps. thumb.gif

Personally, I'd recommend getting a GTX 780 and banking your extra cash. Two 770's is going to cost $800 total versus $650 for the 780. Buying into the 780's extra VRAM is good for future proofing and the wider memory bus will help too. When a single 780 isn't enough (that won't happen for a long time) you can get another one. They will have fallen in price by then to somewhere around $400-500. Take your $150 you saved and put it with some extra cash a year or so from now.

But anyway, that's a personal suggestion. To your actual question, all GTX 770's have a 6 and an 8 pin connector. I'm sure some non-reference models might have it, but I've yet to see them yet.

You could do what this guy did. 8 pin and 6 pin connectors are identical with the exception of the 8 pin connector having a pair of extra grounds.

If you're going 2x 770 SLI, I'd definitely recommend getting blower-type cards to aid in temperature management. Dual-fan cards (like the MSI Twin Frozer or Gigabyte WindForce) exhaust too much of the hot air into the case, which especially is a bad thing considering the Boost 2.0 functionality is highly dependent on temps.

If you have the necessary funds, I'd pick the EVGA GTX 770 Superclocked w/ TITAN cooler (model 02G-P4-3771-KR). Each one comes with a free backplate as well, which is a nice bonus.

If you can't afford the TITAN-style cooler, they make a similar Superclocked card with a more cost-effective shroud (model 02G-P4-2771-KR) which also comes with a free backplate as well.

I checked the power connectors for both models, and they're a 8+6 configuration.

i have a ton of case fans though so it blowing into the case isn't really a problem.
what do you think about the asus one or the evga acx cooler? to be honest i dont really like how those look, if i got a 6-8 pin converter would i lose any performance?
