Hi

as the tittle says i am about to buy new Graphics card that requires 6 pin & 8 pin but my existing PSU only has 2 x 6 pin.

Will connectors still fit or do I need to buy a convertor?
 
Didn't know you could turn a single 6 pin into an 8 pin, I thought you'd need 2x 6 pin.

The PCIe device will draw 150w through the 8 pin when connected as opposed to 75w of a 6-pin. It works fine.

edit -

so 75w through the pcie lane
75w through the 6 pin
150w though the 8 pin

giving a total 300w

the only thing is the cable might run slightly warmer than a dedicated 8pin cable but nothing to worry about.
 
Huddy is that adapter you linked the right one? I thought CPU and PCIE 8pins were different shaped (keyed to only work in the right socket)?

Have you read up reviews on the GFX card your buying to see if it comes with a 6-8 pin adapter? (My 7990 came with two and I have had one with many other cards).
 
While a converter will work i would question running a card on them as it means your psu is having to deliver a load it was not designed for
