Is the PSU enough?

[thewingnut13]

Hey everyone. I have a Dell XPS 420. I put this aftermarket PSU into it.

It maxes out at 550W. But is a good quality of PSU. Will it run my system with a GTX 260 in it? Thanks.

Windows Vista Home 32 Bit
Core 2 Duo E6850 3.0Ghz
EVGA 896-P3-1267-AR GeForce GTX 260 Core 216 Superclocked Edition 896MB (Right now it has a 8800GT)
Sound Blaster Etreme Music
TV Tuner Card
2 X 320 GB 7200 RPM HDD in RAID 0
2 X DVD -RW Drives
4GB 800 Mhz RAM
Assorted Neon lights in case

Yes it should be able to handle a GTX 260. Based on your list of components you're at a little over 400 watts.

Here's a link to a psu calculator where you can list more detailed information about your system and see what you might need:
