IS 525W PSU enough for dual Gtx 260 1.8gh?

here are the parts that I ordered

Intel Core i7 920 (2.66GHz, 8MB Cache)
6GB Triple Channel 1333Mhz DDR3
Dual 1.8GB NVIDIA GeForce GTX 260 - SLI Enabled
640GB - SATA-II 3Gb/s 7200RPM, 16MB Cache HDD
525W PSU
Alienware 19-in-1 Media Card Reader
Genuine Windows 7 Home Premium, 64bit, English
Single Drive: 24X CD/DVD burner (DVD+/-RW) w/double layer write capability

this is for the ailenware aurora. I recently purchased it with that specs.

I ordered the dual gtx 260 video card, because dell representative recommended. he really has not mentioned about the PSU; however, I do not think that 525w PSU would not work on the system that i have with dual gtx260 video card..

I really need an advise for this issue.. if 525w is not enough for the system and the video card that i have, i need to return the product back to dell.

please help me with this issue

It's enough to run it, but just barely. That's cutting it closer than any builder should.

525W for a single GTX 260 system is fine (500W is recommended). I wouldn't go any lower than 650W for two cards in SLI.
