ASUS Dual OC Edition 8GB Geforce GTX 1070 SLI

[kingdusty]

Hey guys!

 

I recently got an ASUS Dual OC Edition 8GB Geforce GTX 1070 and am looking at possibly getting a second and running them in SLI.

 

My biggest concern is PSU, as I have never done SLI before. I was also looking at the ASUS HB bridge to accomplish this.

 

I built my PC quite some time ago(~2012) and it is still my main work station and running great - I don't game all that much but I do a fair amount of video editing as well

as application development in Unity/Maya/Blender/Photoshop. Overclocking is not really something that I would be doing much but it would be

nice to know that I can.

 

So the specs of my pc are as follows:

 

ASUS P8Z77-V

Intel i7 3770k

Arctic Freezer i11 CPU Cooler, 150w Cooling Capacity (not sure if that means it uses 150w or cools this wattage of CPU, assuming it means cools, but figured I would include this)

16gb DDR3 1600 (PC3 12800)
Corsair Enthusiast Series TX750 v2 750w PSU
x2 Optical Drives - One is bluray and the other is DVD

TP-LINK Archer T9E AC1900 Wireless Dual Band PCI-E Adapter

Rosewill RC-400-LX Network Adapter PCI 1 x RJ45

Samsung 850 EVO 2.5" 250GB SATA III 3-D Vertical Internal SSD

x2 Seagate BarraCuda ST2000DM006 2TB 64MB Cache SATA 6.0Gb/s HDD

x1 Seagate Desktop HDD ST3000DM001 3TB 64MB Cache SATA 6.0 (Currently disconnected - does not always work)

x4 120mm fans 3 for intake 1 for exhaust

 

Windows 10 Pro x64

 

Not sure if this makes a difference but currently my one 1070 is running four displays.

x2 LG IPS 21.5in 1080p, x1 LG 34in 3440x1440, x1 LG TV 40in 1080p

 

I don't think these make a difference either but here are more peripherals.

Keyboard, Mouse, Microphone and 5.1 Surround Sound.

 

I have been looking around and have read anywhere from 550-750-850 but was curious about my exactly set up!

 

Thanks guys!

the PSU seems like it can do SLI, check the amount of PCIe power plugs to make sure it can do it 

 

any HB SLI bridge would work (assuming)

The PSU is good enough, don't worry about that.

Single 1080ti would be a better choice though.

For editing and rendering, either that, or a 980 Ti SLI setup (more CUDA cores than a 1070, though less VRAM).

providing you have sufficient 8-pin connectors from the PSU (you need 4 total) the PSU will handle it no problem. each 1070 will draw about 150watts at 80% power so maybe factor in another 25 watts each for over current and you're at 350 Watts just on the cards. maybe factor about 90-100W for the system and you're at 450 watts. If you have a UPS, make sure you're not over the inverter's power delivery limit.

Alright great! Should I be cautious with overclocking? Or will the 750w run everything fine?

 

I really don't follow up on tech, when I upgraded from the GPU that I built this PC with in 2012 (Gigabyte AMD Radeon 7950) I just googled what the best bang for your buck graphics card was which was showing the 1070 pretty much everywhere.

You can OC, there is a headroom. 1070 is not that power hungry.

I have x2 8 pin connectors. The card only takes one.. I think. lol I was assuming one per card.

OH! I was thinking this was the one with better VRM. my bad. yes, you should be good to go then.

Alright phew! I just wanted to make sure my work station wouldn't blow up if I dropped another 1070 in it - potentially nerfing years of backed up files and such.
