components.

Good catch!

If the OP's PS does have non standard wiring connections then a new PS
wired by the normal standard certainly could cause damage if the 12 volts
out of the supply was connected to the pin(s) normally used for 5 volts on
his MOBO.

I have a dell insp. 531s with a 250W power supply. Dell support says
upgrading to anything over (like 400W) would potentially fry my
components, is this true? Is it safe to upgrade to a higher wattage?

They say that because they supply specific power supplies for each model,
and there is no provision..

Two possible obstacles. There may not be a 400w PS available in the
physical size fitted to your machine.. you will have to take out the 250w
and compare..

Also, Dell used to customize the order of wires which go into the
motherboard plug. I don't think that they do this anymore, but it would
be wise to check first..

Highly unlikely. Dell do not encourage users to upgrade their equipment.by
replacing the innards with upgraded parts. They would sooner the user buys a
better model..

They do if they think you'll buy the part from Dell. Dell often makes
more from a single accessory sale then an entire PC sale.
