As I mentioned before, I currently still have a 3rd 9800 GTX+ I never installed in my computer, When I ordered my original PSU, I thought I was unable to hook up 3rd 9800 GTX+ video cards in SLI because of the power cable hook ups I was limited too.
The computer in this video has the same PSU, Tagan BZ900 with 3 XFX GeForce 260 GTX in 3 Way SLI.
After doing some research, I have come across 6 pin PCIe Splitters. I am not a “power guru” so I am not sure if I can use these types of splitters but if I can, how would I hook it up properly to avoid power issues?
Thanks for the reply, unfortunately Tagan went out of business and the PipeRock type modular cables are no longer available to purchase.
On the back of the PSU there are 8 PipeRock connections. 4 blue for Sata / Molex, 2 Red PCI-E and 2 Green PCI-E.
I have read on different forums that a good 900W PSU is plently for a 3 9800 GTX in SLI, but I just want to make sure that I am hooking it up correctly, Don't want to turn this project into "Bailout Situation"
Are the connectors physically different for the different lines that connect to the PSU?
What I mean is, do you think the red cord would fit in the blue slot?
I don't really understand why a PSU maker would limit it this way, but maybe it was done with yours.
Also, there may still be cables available on the secondary market somewhere. There could be a broken Tagan modular PSU on ebay that is being sold for scrap parts as we speak. You could potentially get a cable that way.
I wouldn't try to split a PCIE wire into 2x PCIE wires, but 2x Molex into 1x PCIE should be fine if that is the route you have to take.
It would be best to take as much as possible from different power cable ports on the SATA/MOLEX lines.
If you had 4x drives (1 dvd and 3x hard drives or whatever) you would want 1 on each cable and with the 4 molex cables that you need to make 2x PCIE you would also put one on each of the SATA/MOLEX lines.
That would give you two connections to each wire, one a regular drive and one that links to the video card.
Keep in mind the safer bet is to just have a PSU that can handle this stuff natively. One with 6x PCIE built in.
It should work just fine as I described, but it isn't going to win any best practice awards.
