Exactly what psu do you have?
If your psu does not have the required 4 connectors, it likely does not have the power to drive them.
Yes, you can use molex to 6 pin pcie power adapters.
But, I would only do so if your psu is a top quality unit with sufficient power.
You should be looking at a 600w psu.

Need to have the rails split correctly but is should work.
Output+3.3V@24A, +5V@15A, +12V1@30A, +12V2@22A, -12V@0.3A, +5VSB@2.5A
Output+3.3V@24A, +5V@15A, +12V1@30A, +12V2@22A, -12V@0.3A, +5VSB@2.5A

Hi again - I think you mean nrp vc603. There's no trusted review of it, and the OEM,
Solytech doesn't enjoy a stellar reputation. However, if it can deliver close to it's rated specs
it should run 2 7870's in CF.
The specs show 22amps on each of two +12v rails. However, tha max +12v is never the two added
together. If you could look at the sticker affixed to the side of the PSU, and post the figures here, I
\could be sure one way or the other.
Assuming that works out OK, you need to get a molex to pcie connector, such as this:

OK - Thanx - they don't say how much of the 585w total is available for +12v,
but it looks like you might have enough. What I would do is go ahead and try to CF the 7870's.
You'll know soon enough if you have insufficient power. It looks like you'll be OK.
I would however, if you are going to CF going forward consider upgrading your PSU to a quality unit.

Good luck with your CF rig.
BTW, a quality 600w PSU is enough to CF a sys with 2 7870's.
My only concern is the unit being able to deliver it's publ specs. There are a lot
of PSU's that exxagerate and outright lie about their power specs.
Just be sure the vid cards are not on the same rail as the CPU.
