Advise needed PSU

Hi all,

i'm planning upgrading my current PC to a new Intel I7 720 system, and i need an important advise on the PSU.

Nowadays i have this PC:
Pentium 4 530 3.0GHz, Asus P5GDC Deluxe, 1GB Kit Patriot DDR400 CL2.0 RAM, 1x NVidia 7950GT, 2x WD Raptors 74GB SATA, DVD-RW, floppy.
I'm not sure now what is the current OEM PSU exact wattage by i think it's about 350W.
I did sucessfully and stable OC up to 3.75GHz but most of time (like 80% of time) it's working at stock frequency, ie, 3.0GHz.
I think the Intel 530 had 90W at stock frequency.
I have this PSU for about 4 years.

The upgrade i decided to do (CPU, Mobo, RAM) is the following:
Intel i7 720 2.66GHz, Asus P6T, 6GB Kit DDR3-1333 CL9.0 and keep the rest.

Is the current 350W PSU enough so i can keep it and save some bucks?
Or do i really must/should buy a new PSU and in that case what *NOT EXPENSIVE* model do you suggest? (maybe from LC?)

Thanks a lot for all the help in advance.

More about advise needed
  1. I'd get a new one: Antec, Thermaltake, OCZ, PC P&C, Corsair, Seasonic, Thermaltake, or Zalman all make good PSU's. I'd recommend 450W-650W (550W if you want a better video card later).
  2. better get a powerfull psu so you can upgrade your graphics later on, new cards need quite a lot more juice than the 7950gt...
    something like corsair 650tx, $80 after rebate
  3. ^ agree
