Well I left the unit unplugged and the battery removed for about 20 hours.
The symptom has now changed.
-- The battery is still out.
1. I still hear the relays click when plugging in power.
2. Now there is no activity at all when pressing the front panel power switch.
Starting to sound like power supply?

Hi,
This is a generic fixit for PowerPC Macs but always worth a try:
- Unplug the unit from the mains.
- Remove the NVRAM battery
- Leave to stand for *at least* 2-3 hours
- Power up
The issue is the NVRAM (referred to as PRAM on a Mac just to be
contrary) becomes corrupt as the battery runs down. If the machine has
been stood unused for a long time it may have this aforementioned
amnesia.
I have, however, heard a lot of sorry tales of PowerMac G5s suffering
all manner of weird problems with PSUs, leaking liquid coolers and
more. It's worth thoroughly checking the whole system over before
proceeding.
