PC won't turn on, after installing graphics card.

  abolbridge 16:16 20 Jun 09

I just bought a used 3870 off a friend.

The card was working fine, he replaced it with a 4870 so I bought the 3870 off him.

I've got a 600W PSU but it did come with a 6-pin straight off the PSU so I'm using a 2-molex -> 6-pin to power the card.

But my computer won't turn on? Is it the adapter I'm using?

It may be, you may also have blown the card if you have done a lash up

Will it still start with old Graphics Card?

Worth taking each of the molex adaptors from different 'strands' of the PSU. Depending on how the rails in the PSU are set-up it may allow for more power throughput.

Stating the obvious, but don't power too many devices from one PSU rail.

I'm using a Chiefmax 680 Watt.

Is that just not setup right to run a Sapphire 3870?

I don't know Chiefmax, but a bit of googling says that it's an economy brand.

If it's new, fresh out of the box, then it should be OK.

The rule of thumb I use for economy brands is to assume that the power output is 50% of it's advertised value (340W in your case). It has been argued in the past that this rule is too conservative.
