Minimum power supply ofr ATI 4770

I've only got a 375 watt power supply in my XPS 420. Can't really upgrade the power supply but want beter graphics than I get with my ATI 2400. I know 375 is below the recommended minimum for a 4770, but does anyone know if it will operate in this machine OR have recommendations for another upgrade card? Thanks.

    no
  4. You should have no troubles running a HD4770 off that power supply, Dell units are underrated, just check you have the 6 pin PCI-E connector the card needs and you're good to go.
