Quick Version:
Bought a Quadro FX3700, PC’s PSU doesn’t have a 6 pin PCI-E power socket, case doesn’t accept standard PSU so can’t upgrade that
Should I return the FX for a card without the 6pin socket or get a Molex to 6pin adapter cable?
If swap, what card would you guys recommend as the ‘best’ OpenGL 2.1 card to run photoshop & dual monitor (no 3D or gaming required) without that extra 6pin socket?

Detailed version:
Colleague recently upgraded to Adobe CS4 Design Premium (Photoshop, InDesign, Bridge, et al).

It’s a new work machine, so he’s stuck with a HP Compaq dc7800p tower (not small form factor), but internally she’s a nice little pc with quad core intel, 4Gb ram, etc.

He’s just bought a Quadro FX3700 as recommended for photoshop etc, without breaking the bank.

Problem:
PSU is a pants 365w 12v@15A jobbie, and it hasn’t got the 6 pin PCI-E power plug.
So we popped to PCword & got a nicer one, but the case won’t take a stock PSU, and it turns out HP don’t make a better one for that case! How cr@p is that!!

So should I get one of those molex to pci-e plug adapters, or return the FX3700 & get the best graphics card possible without a 6 pin socket?

If so, what’s IS the best card that doesn’t need extra power & will run with this pants PSU??

Hope somebody can help here,
Jay.
