GTX 660 SLI QUESTION

post #1 of 28
Thread Starter 
Hey everyone, so I just bought myself a EVGA GTX 660 3Gb, and then newegg ran out before I could buy a second one.

My question is, since I have just the base EVGA 660, can I SLI it with a Superclocked one? Since they are the same chipset?

Also, how much power should i run with 2 660's, and a 3770k @ 4.6Ghz? I'm thinking of getting myself an NZXT HALE90 v2 1000W.

And with these two cards in SLI, can I run 3 1920x1080 LCD monitors @ 60fps on COD: Ghosts and BF4?

A quality 650 watt can run those. Maybe 750 If your overclocking. Just make sure you get another 3gb one. The clock speed doesnt matter.

With adjusted settings you can get your 60fps on that monitor setup.

Awesome!
I just have a Cougar S700 right now that I got, way back when I first started building, so I'll probably get the 850w NZXT psu then, mostly because it matches the color scheme in my fractal.

But thanks for the quick answer, that was definitely what I needed to know!

Those NZXt psu have a bad ripple under load. Its in the reviews.

****, alright, well then what PSU would you recommend?

I lack the knowledge to make one, though I am sure it's simple.

Otherwise I would.

Way to much PSU. With my Sli 770s and 3770k @ 4.3 im pulling a little over 600 on the killowatt gaming and a little more benching. 750w has been plenty for me. As for the surround setup, COD isnt that bad at 5760 x 1080. 60fps is probably doable with the settings a little conservative. Gaming is surround is a lot of fun. I enjoy it anyway.

Not ALL NZXT PSU's have bad ripple under load; please link me to the review that says that says all NZXT PSU's have bad ripple.

Are you sure youre not referring to the cheaply made NZXT HALE82?

http://www.hardwaresecrets.com/article/NZXT-HALE82-N-650-W-Power-Supply-Review/1565/11


The PSU that OP has is the NZXT HALE90 v2

http://www.hardwaresecrets.com/article/NZXT-HALE90-V2-850-W-Power-Supply-Review/1750/10

It has pretty solid ripple on the 12v and doesnt seem like a bad contender like its cheaper counterpart, the HALE82. The HALE90 is a gold unit and the HALE82 unit is a bronze. Big difference there too. Unlike the HALE82, the HALE90 is also based off FSP PSU's, also previously made with Super Flower PSU's.

On load distribution; it maintained well above 88% efficiency

http://www.hardwaresecrets.com/article/NZXT-HALE90-V2-850-W-Power-Supply-Review/1750/8

Please do not make blanket statements about all PSU's. If you are not sure; double check before posting misinformation on a public forum like this smile.gif

IF OP is looking for a good power supply; check this out http://www.overclock.net/t/183810/faq-recommended-power-supplies/0_30

The NZXT HALE90 V2 should be enough for his setup; a little more than what he needs; but honestly an efficient 650W PSU should do the job here. I had two 670's overvolted to 1.212v and an i5-2500k (higher TDP than the 3770k OP has) and i was using a 650W Rosewill Capstone and it was definitely enough.

Those 660's pull around 250W on full GPU stress. Probably less most of the time; this is like 100% usage. The CPU will probably pull less than 100W and you still have plenty of wattage left for fans, even a 20W pump if you plan on going custom water cooling.

I had this whole set up on 650W; so honestly OP if you buy a 750W or 850W youre going to be wasting your money on extra wattage you wont even be using. (If you dont like your current PSU).

If you DO like it; then i say just stick with it. Its a pretty decent PSU that isnt like the cheaper counterpart; HALE82.

Also: 1000W Is INSANE OVERKILL. You dont need a 1000W PSU for this. I had two 670 FTW's (680 PCB's) and a 2500k overclocked and 650W was enough (even with a full water cooling set-up with an MCP35X pump)
