Hey guys.
I´ve just bought myself a GTX 670 AMP Edition and I am seeing now that the GPU needs 2x6-Pin cables to power it up.
Well,my PSU is modular and a while ago,I´ve lost some of its cables.
Now I only have a 6-Pin and 8-Pin for the GPU.
Will running the GPU with the metioned adapters,Dual MOLEX-to-PCIe 6-pin Adapters, affect performance in any way?
The PSU camed with 2x6-Pin and 2x8-Pin,but I´ve lost one of each.
The PSU in matter is the Cooler Master Real Power M620,I used it to power up a 7970 a few weeks ago, until I returned it because it was failing on me(coil whine,buzzes,abnormal temps,etc).
Cheers guys.

Think the GTX670 uses a little less juice than the HD7970 so power wise it's OK.
It is not a good idea to run powerful cards off molex/PCI-E adaptors, though, Molex connectors are not really designed to handle the high currents that a graphics card can draw, try contacting Coolermaster support they may be able to supply a replacement 6-pin cable or your local small computer store may be able to downgrade the 8 pin lead to 6 pin.

For the 2x6-Pin PCIe the card requires,I plan on using 1x6-Pin as a normal one,the one that I still have from the PSU cables and the second one I plan on using adapters to run it.
Any problems with this config?
Thanks.
