Pentium dual core e2180 2.0ghz (can overclock to 2.5-3.0 ghz)
1280 *1024 monitor
4gb ddr2 667 ram
250 gb hard disk.

My psu ratings are
+3.3v=15A
+5v=16A
+12v=15A

That card should work fine with the pentium dual core you have.
I would suggest at least 400W and 19A minimum on the +12V just to be safe.

Any quality 400 450 watt power supply will do the job

Judging by the fact that there are four "max" wattages, I think it's anyone's guess to what the true wattage is of that PSU.

I bought and using 6670 on this psu from 3 days and it is not showing any problems .It is not heating and sudden crashes etc. Is there any way to know that the gpu is not getting enough power ?

BSOD, computer randomly restart, and sluggish performance when playing games.
If it does not show any problem then you are good to go.

it must be ok, but a psu with 19amps or high is actually recommended,but if there is no problems with the performance of the pc it should be ok

the minimum requirement is 500W..
i would suggest corsair, antec and seasonic brands.

quality and trust as i would know them to be.

it is actually 400w or above,as it is written on my hd 6670's packaging
and yes, the cheap psu's may only provide half of what it is written on it's label,so always go for brands like corsair ,seasonic or antec

Only 15a on the +12v rail is a significant concern. You might get by for a while, but I think
you've got a ticking time bomb.

GPU "requirements" are to be taken with an boulder-sized grain of salt.

The OP's entire system likely draws less than 200W from the wall under full-load so a quality 250W PSU with the right rail balance would be enough. With my PC under full CPU+GPU load, my RS1000 UPS reports 260W power draw but that includes the PC, 24" LCD, 28 ports network switch, broadband router, modem, USB hub and an external HDD... so my PC itself is likely under 180W.

There are two reasons why GPU manufacturers grossly over-inflate their "requirements":
1- they have no idea what other hardware might be in people's system so they base their estimations on the worst-case they expect from people using the particular model you are buying
2- they cannot know beforehand how good your PSU is and due to the broad range of crappy PSUs out there, they have to base their recommendations on the worst PSUs they expect people to use with their GPUs

So you end up with manufacturer "requirements" that are 2-3X what is actually required.

you're right.

but i will still suggest brands like Corsair, Seasonic, Antec, or Silverstone Strider at least.

dont go for some $30 psus...

That pentium dual core doesn't require much power since it's a 2GHz+ chip.
You should be safe as long as you are not doing any overclock your system will run stable without problem.
