neone tell me the capacity of a Dell system PSU?

[jlo56]

i have a Dell P4 1.3 ghz, 400 mhz bus, and my PSU is about 250w, tho i dont kno if this is the max capacity output. Because dell uses nonstandard ATX PSU with specialized voltage, some ppl say that capacity is actually higher than 250w (around 345w i heard). Can anyone who knows about dell PSU confirm or dispute this?
here some specs about my psu:

DC power supply:
Wattage
250 W
Heat dissipation
913 BTUs (fully loaded computer without monitor)
Voltage (auto-sensing)
90 to 135 V at 60 Hz;
180 to 265 V at 50 Hz;
100 V at 50 to 60 Hz for Japanese computers
Backup battery 3-V CR2032 coin cell

any suggestion appreciated thnx

Knowing OEM's, i would say about 2 watts more than the max the computer will ever draw

Yeah, it's probably just enough.
I gave my dell 8200 (2Ghz willamette 256mb PC800 RDRAM) to my dad and I built this rig (in sig). I noticed when there was heavy HD swapping going on, it sounded like it was losing RPM's! (7200rpm)

Plus, it's a P4 system but it doesn't have that extra 4pin plug going onto the mobo, only the really big one. That seems kinda wierd since almost ALL P4's have that extra 4 pin......

Doesn't Dell customize their PSU plug and their ATX design slightly. I think I read in another thread earlier, but can't find now.
