G'day lovely people,
I have a small issue with my current PSU, it doesnt have the correct connections for my planned upgrade to dual 770 SLI.
System currently as followed; powered by
Thermaltake toughpower gold 750w
i5 4670k oc'd to 4.6 @ 1.3v
thermaltake NiC f3 cpu cooler
g. skill ripjaws z 2400 ddr3
msi z87 gd65
asus direct cu11 gtx770
samsung 840 240g ssd
lg DVDRW drive
WD 1T blue hdd
avermedia tv card
1 x 150mm fan
2 140mm fans
3 x 120mm fans
asus VG278HE 144hz 3D 1080 monitor with nvidia vision 2
Now, as I have started gaming in 3D a single 770 just isnt quite cutting the mustard for ultra game specs at a decent frame rate. (Tomb raider drops to around 25 fps at ultimate specs with tressfx ON)
I want to get another 770 to SLI but the PSU only lists modular outputs for 1 GPU.
The semi modular PSU has the following connections listed on the box
2 x 8 pin PCI
5 x 6 pin peripheral
Does it matter if im powering a GPU with one connected to the 8 pin PCI and the other to the 6 pin PCI peripheral connector ?
So I have a couple of ideas but not sure if I am going to cause any damage if I do.
Option 1
run 1 of the 2 PCI 8 pins to each GPU and then use 1 of the addiotional 'peripheral' 6 pin connectors to each GPU.
Option 2
use Molex to PCI 6 pin adapters.
Option 3
buy a Corsair AX860.
Option 4
Sell the 770 and buy a 780 and then keep current PSU and connections
So with those options, option 1 is my preference as I wont need to buy anything but the 770.
Im very hesitant about using the molex adapters but it could be perfectly fine.
And I really dont want to buy a new PSU but if that is the only option then Im gonna have to
not sure if the 780 is really worth the extra hassle (money, trying to sell the 770 )
So any thoughts or other suggestions would be absolutely marvelous.
Many many thanks to all
