does my power supply need a gfx card connecter for it? do gfx cards minimum require power go down over time? like good cards now in a year from now can have lower wattage?

First, which power supply do you have? You need ONE 6 pin pcie connector.

the only good power supply you posted is the Corsair unit.
The rest are junk to be avoided all all cost.

Do not mean to be harsh just dont want you to waste your money and possibly kill your comp with a bad power supply.

ahh i completely understand, after reading reviews and stuff on websites, i picked that one plus it has $10 discount so only cost lil more than the other *** and free shipping..thanks a lot!

ok ordered it, a bad psu will make a comp freeze up?? i hope i fix my issue
