So I'm just about to go all in with these 2 gtx 780ti's, but before I invest I would like to make sure the power supply I get will be enough for all the doodads I plan to stick on it to.

This is the full build which includes all the extra stuff.

I'm hoping the PSU I'm planning on, which is the EVGA SuperNOVA 1000 P2 1000W Platinum, will be efficient enough to handle all of this stuff.

Oyeah, the Hue LED thing is this

Hi, It will be enough. You can even Overclock. Though is is a personal advice: Dont get MSI, The last msi product did cost me 300$.

I woud get a refrence cooler since youre going SLI. Or take a look at Asus 780Ti directcuII or 780Ti Ftw from Evga. The VI hero (which i have myself) is a really good borad, I recoomend it. I guess the Z97 ver. will perform even better :)

Considering the msi 780ti is actually the cheapest outside of the reference model. It sways from around £470 to about £510.

I think it's a toss up between the MSI twin frozr, or the EVGA classified right now.

And thanks for the answer regarding the Power supply.

1000w Platinum is way overkill. 850w is plenty, even with overclocking headroom and longevity. That's just 50% more cost for no gain. I would even say the new G2 line from EVGA is higher quality too.

An overclocked system running a pair of 780 Ti's in SLI will draw around 650w at full max load.

I currently have a 780 Classified. and no other 780 can compete with it. best 780Ti hands down. The reason i arent getting it to my next card (780Ti) is because its about 200$ more than the DirectcuII card :/

I'm using two MSI 780s (MSI GPU loyalty, have no clue why), granted they're not 780 Tis, but the power consumption is still the same. I'm running an i5-4670k @ 4.2 GHz, and both GPUs with mild overclocks, and still have plenty of room to push it. I'm using a Corsair AX860, and is the exact PSU I'd recommend. 850W is more than enough for dual 780 Tis.

The Ax860 is over 140 quid there, whereas the 850 G2 from EVGA is only 92, and is the same, if not better, quality as the AX.

Thanks for the best answer. And those 780Ti Classifieds are the best card(s) on the marked. Congratz mate! :D
