I've got a computer here with a Xilence power 550W PSU.

That PSU is built for silence as is the entire computer.

The PSU's large fan does not spin innitially when turning on the
computer, and does not spin up for some time unless gently nudged with
a stick.

Even tho such behaviour would seem normal if the PSU's temperature
regulation is providing the fan insufficient voltage to start up when
the PSU is still cold, I am not used to seeing it. My usual brand of
PSUs is LC Power and their regulated speed PSU fans always spin when
the PSU is turned on.

Anyone with experience using these Xilence Power PSU's? Is it normal
for their fans not to spin innitially or am I looking at a brand new
computer supplied with a PSU with a partialy busted fan?
 
A fan either has voltage applied to it or it doesn't. If the fan
starts spinning when prodded with a stick, it's not working
properly. And unless a PSU is designed to operate without
any airflow, a lack of it will likely cause premature failure.

Well normally, a brushles fan (like the ones used in computers) needs a
small voltage peak to start spinning (if you nudge the fan with a
stick, you've gotten it spinning, then the low voltage is sufficient).
The cheapest way to implement temperature regulated spinning does not
produce this peak, thus it would be normal if the PSU is absolutely
cold that the fan would not spin.

Thus I really need somebody to confirm that propperly functioning PSU
of the same brand spins from the very start.

Have you talked to Xilence.I notice their website has almost no info.But
there is a contact.

Okay... for all those that may be reading this looking for the answer,
Xilence said: "the fans should run all the time the computer is turned
on. If not, it's defective, so please contact your computershop to get
it exchanged."

Thanks for the help, folks.
