Corsair tx650 v2 xfire 6850 with one problem

I don't have my build complete yet but here it is.

Mobo- MSI Z68A-GD55 (G3)
CPU- I5 2500k
GPU- xfx HD6850
PSU- Corsair TX650 V2
Case- Xion AXP970-001BK Predator Gaming Mid-Tower Case
RAM- Corsair vengeance 2x4gb DDR3 1600MHz
after market cpu cooler- cooler master hyper 212 evo

My question is this:
I own one xfx hd 6850(requires two 6 pin pci-e connectors), I am thinking about ordering in another but sadly my tx650 only has two 6 pin connectors. I was thinking of ordering another that only requires one 6 pin and using a 2xmolex to 6 pin pcie(which is what I am sketchy about), Will this be nice and stable? It would be my cheaper and preferred option.

Or I could TRY and sell off my current 6850 and go for maybe a gtx 570(1280mb version).

just use the molex to 6 pin connectors. Will work fine.

Your Corsair TX650 V2 has enough power for 2x HD 6850 CFX.

Nothing sketchy about using the molex to PCi-e adapters (except maybe the way it looks). It works the same as any 2nd PCI-e connector would.

Many cards include the molex to PCi-e adapter in the accessory pack for situations just like yours.

Does the 6850 run really hot in crossfire?
Also does the HIS come with a crossfire bridge? The xfx was the worst, 2 six pin no molex adapter no crossfire bridge, nadda.
Also I am a little afraid to overclock, mostly just on the cpu, I probably won't overclock the gpu's unless I upgrade to water cooling later.

You sometimes see one video card running hotter than the other, especially when the cards are stacked very closely together.
But it's usually not much hotter than just a single card.

That model of HIS does not include a bridge in the accessory pack.
Some of the other models will have a bridge (plus molex adapter)

Here is another model of HD 6850 with a bit more in the accessory pack:

ASUS EAH6850 DC Radeon HD 6850
