Hi, long time lurker. Love the forums.

I recently decided to build a nice system, i5 2500k, 3x 6950s, SSD, triple monitor, etc.

The PSU I bought was a Silverstone ST1000-G, to ensure I had enough power for all my stuff, and because it said it had enough PCI-E connectors.

It arrives, and I see the PCI-E cables. It has two 6+2 pin cables, and then two cables that are 6+2 pin, but also Y off to a 6pin connector (attached to the 6+2 pin connector).

You can see what I'm referring to.

My question is: am I able to connect those Y'd off 6pin connectors to one of my 3 cards (while the 6+2 pin part is also used)? Or will I have to return this?

An off topic question: would that PSU be enough for a 6990 + 6950? OC's on CPU and GPU.

Thanks a bunch guys. Really appreciate any help you can give me.

It will handle tri-fire, but won't leave you much room. But definitely handle it.

Yes you can connect it. As long as it is a PCI-E cable it can be connected to the card. If its physically possible generally you can connect it. Only thing you should watch out for is not accidentally connecting the 8-pin mobo cable to the card, but other than that it's fine.

Connecting the +12v EPS connector into the 8 pin PCI-Express header isn't possible. IIRC, they're keyed differently.

A good rule of thumb for (reputable) power supplies is you can connect as many graphics cards as you have native connectors for. Once you have to start using molex adapters its time for an upgrade.

I've never tried it personally but quite a few PSU manuals have a warning against mixing up the +12v EPS and PCI-E connectors, so I assumed it was something to look out for.

Idiots with strong hands have been known to force EPS 8 pins into PCI-E connectors and vice-versa. Just take it slow and install it careful, and you will be fine.
Assuming the 6950 uses a pair of 6 pins, then you should be fine running each card off a single cable with the twin connectors, the 6950 isn't a massively high draw card. I'd not recommend that for GTX580s or the like, but for your cards it'll be fine.

What are you talking about... this is a 1000W unit, a good 850W can easily handle three 6950s.
