I have an i9300 that I've dropped a 7800gtx into -- it's running the XPS2 BIOS so it needs 130W to run at load, but will limp along on 90W. I bought the Duracell adapter from Dell and received it yesterday. I plugged it in to an AC outlet and fired up my laptop, it didn't complain about the power supply during POST and the cpu ran at full throttle during use.
Unfortunately, I'm finding out that when on 12v DC power in the car (as I am right now) it seems to only operate at 90W instead of 130W. When I POST'd, the system complained that the 90W power supply wasn't enough -- "press F1 to shutdown." Bummer, so I booted up off the battery, connected the power supply, and sure enough I can see that my CPU won't throttle past ~700MHz. This is exactly how the machine behaves when on the dell standard 90W AC adapter. I'm really disappointed and I expect I'll be returning this. Just thought others would like to know since I can't seem to ever find information on the forums regarding 130W dell adapters (specifically DC adapters).
