i will buy a new config :

intel i5 760.
G.SKILL Ripjaws Series 4GB (2 x 2GB) ddr3 1333
GIGABYTE GV-N460OC-1GI GeForce GTX 460 (Fermi) 1GB

I would like to know if my Fortron Green power 400w will be enough to run it?

Possibly, 400 W is more than enough, but then again it's relatively generic (Fortron PSUs are actually not too bad apparently).

I don't have a warm fuzzy about the PSU. I looked on newegg. It has two 12 volt rails, max current of 14 and 15 amps. I have no idea what the total maximum is.

Down at the bottom of the specs list:
"300W Total Output
High Efficiency | Low Power Consumption
RoHS | G.P Qualifications
Active PFC
Complies with EN61000-3-2
Supports Serial-ATA Power
Complete Short circuit Protection on All Outputs
Low Ripple & Noise
100% Burn-In Under High Ambient Temperature (50°C)
Under 30dBA Low Noise Design

Designed, engineered and manufactured to precisely qualify for environmental friendly, GREEN Power Supply status, this 300W ATX12V 2.01 power supply unit features RoHS | G.P"

So if it's really a 300 watt PSU, Maximum 12 volt current cannot be over 25 amps.

And ATX12V 2.01 makes it an old , now obsolete PSU.

A 1 GB GTX460 needs about 10 amps and the CPU will need around 8 amps. That's pretty close. You can try your old PSU, but don't be surprised if you need a new one.

I think that might be a printing error @ NewEgg.
SilentPCReview did a review on that PSU and ran it up to it's full 400w rating on it's load tester. It did OK. Review here.

But I also agree this might be cutting it too close for comfort. PC's 'age' over time and lose the ability to output it's full rated power.
If this Fortron is 3 or more years old I don't think I'd try it with expensive new parts.

WR2, could be a printing error. OTOH, look at the date of the article - 2007.

More importantly, look at the total 12 volt current at just under 400 watts - about 21 amps. :( 

I don't think that is enough for a GTX460.

It could be just a function of how SPCR setup the DBS-2100 PSU load tester.
They mention that loading formula is a standard used by 80 Plus testing program and not a 'max effort' on any rail.

Have you found anything that tells you that is a good PSU?

You're adding $700 of premium parts and you want to power it with what looks like a very budgety PSU. At least it gets good reviews from NewEgg customers. But you never know if it's just a "it's good because it works" review.
A good PSU is no less important than a good CPU, video card, motherboard and RAM, at least IMO.
I would not choose that PSU if I were in your position. I'd want to match the quality of the other parts as closely as I could.

ok, can you tell me a good psu not too expensive?

The KINGWIN have only 4pin connector(cpu) but the motherboard need 8 pins. It will work?

I missed noticing that. It should work but it's better to get a PSU with an 8pin EPS aux CPU power connector anyway.
The final price after rebate is only like $4 or $5 difference for that OCZ ModXStream Pro 600.
