How much power in terms of watts (PSU) would I need and one that doesn't have a 12v rail dropping below 11.83v to power a Northwood 5GHZ project?

CPU: P4 2.53GHZ "Northwood" 1.5v in bios
RAM: 1st G.Skill 1GB 400 RAM 2nd 2xCorsair 512MB 400 Value Select
MOBO: GB 8GE800 Pro rev1:1
GFX: Geforce 4 Ti 4200 or Maybe Integrated
PSU: Unknown atm.
COOLING: Dryce @ 40cm Pipe and some Socket mods and Reintention to be done still

What are the specs of the rest of the PC?

Considering that a Pentium 4 HT 2.4C uses around 66W, twice that will be 132W for a 5Ghz P4 give or take 10W. That's just for the CPU alone.
 
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Also is there any vid mods for the Northwood (and yes I'm aware of the S.N.D.S) that will be able to help bump up the voltage to 1.8v +. Yes some resistor and capacitor mod to the cpu area is required for the power to fluently pass into the cpu.

Some Notes: Not a HT cpu. I think it might be a B series Northwood being
Northwood series A: 1.8 to 2.4
Northwood series B: 2.53 to 3+ no HT
Northwood series C: 2.6 to 3+ with HT

Otherwise I'm not really sure.

With those relatively low specs, I'd imagine that the even the $50 Corsair 400CX would be enough.
 
Well, if you need specific recommendations, it would help a lot to know what options you have available to you and what the pricing is. If you can get Seasonic units where you are, they have some lower-wattage models that are probably pretty inexpensive. The 300W or 350W models would be plenty for your needs.
