I have a Dell XPS 420 with the stock 375w power supply - It's Dells house brand I think?

I would like to put in a 650w or 750w but someone wrote somewhere that the Dell motherboard for this can only use Dell PSU 375w and no more than 425w???

Some guy on youtube said he has a 650w lsp ultra in his and it works fine!

What's the story guys can I fry the motherboard on this thing or is it Dell sales fiction?

At one time Dell used propriatary power supplies, and the motherboards were designed to use these power supplies, you could not use another brand without some rewiring of the connector. Dell no longer uses propriatary power supplies. The only limit that I can think of is a possible case size problem.

Here is the on-line owner's manual for the Dell XPS 420 desktop.

Here is the section on replacing a power supply unit. All the technical specs are for 375 watt and 425 watt models. I didn't see any comments about being able to upgrade to a higher wattage model.
