I'd like to know how good these Bitfenix cables extensions are (the single sleeved ones) since my PSU's (XFX 1050 80+ GOLD) cables are way too short, also, my graphics card has an 8 and a 6 pin plug and so far those cables come with an 8 pin pci e connector, would it be wrong to plug the 8 pin in the 6 pin and have the other 2 pins hanging around? Thank you.

They should be just as good as any. If it is 8 pin PCIe power no problem having the pins hang out.
