That is possible, but only if the PSU has enough power. What PSU is it, with specs, and what graphics card?

Go for the 560. The 465 is a strange modification of the 470 I believe and is generally slower than the 460 1GB, which is slower than the 560.
The 560 appears to require only 24 amps on the +12v rail, while that PSU supplies 37 amps on a single +12v rail. You should be OK using the one 6-pin from the PSU and then using an adapter (that will come with the 560) for the second input on the card. The adapter will be two 4-pin molex to a single 6-pin adapter.

Are you sure the PSU has a 6-pin ???? According to the specs on the listed PSU it has NO PCI-e connector ! so in order to use it you'll need to use 4 molex connections and 2 adapters ! (and that will not leave very many Molex connections left for other parts and it has only 1 SATA connection as well)

Ok then was just going by the Link you posted where it says :

Quote:
PCI-Express Connector No


and
Quote:
Connectors
1 x Main connector (20+4Pin)
1 x 12V (P4)
8 x peripheral
2 x SATA
1 x Floppy


No mention of any 6-pin so is the 250 you are using connected using an adapter already or is the PSU different from the one listed ?

I don't know who is wrong, but from
http://www.buy.com/prod/xg-vortec-600w-atx-12v-ac-power...
In the product summary, it says, "20 to 24 pin adapter, eight peripheral and two floppy cables, two SATA connections and one PCI express power connector"
Anyway, he said it has one, so don't worry.
Even if he used adapters for both 6-pin sockets, the PSU still has more than enough power (37a for a 24a card) for the 560.

Correct -- Just wanted to be sure he had a second adapter if it was going to be needed since the GPU normally only comes with one but since he already has a card using a single 6-pin connection he'll have it - so all should be fine !

Any of the Antec Gamer Series would be a nice choice. If you list your system specs, including the new gpu(s), we can recommend a wattage. Or, you can use this.

Hmmm, you may need to go with the 750 to be safe, but the 620W might be possible. Anyone else have thoughts?

I'd keep it. You'd get about $50 for it on eBay, but it's a bit of a bother. The people out there who do have physx dedicated cards usually use the 9800s or 250s.
