is this psu decent enough ?

Solution
According to the datasheet for that PSU, it has a 34A +12V rail. The HD 6870 is a 250W Max TDP card that will draw 21A fully maxed out.

If you are looking to put a 125W processor in the system, it will draw another 10A from the +12V rail. So by the time you add in the drives, MB, fans, etc... you are getting close to the current limit of that PSU's all important +12V rail.

Again, based on the +12V rail's current capacity, it doesn't fall into what I would consider a 'real' 500W PSU. More akin to a 350W - 400W. What is your price limit for a PSU? This is a good budget PSU depending on the availability in your area. It has 2 x 34A +12V rails...

It's not a very high quality PSU. And definitely not 500W with 2 18A +12V rails. More along the lines of a 300W-350W PSU. Not really enough for the HD 6870. As to the CPU choice, it would help to know what you want to do with the PC you build and the price range. Intel and AMD processors use different motherboards.

1-how do i know the psu is decent or not and deliver what is says ?
2-the pc would be for gaming at 1280x720 .The cpu maximum price should be something like a phenom x4 ii 955

1) Here is a list of PSUs in a sort of hierarchy layout rated from best to worst. Stay away from tier 4 or worse.

2) I'm going to assume your MB is an AMD socketed board since you are considering a Phenom II. If you give us the make/model of the motherboard, we can determine the processor best suited for you for the least cost. You have to determine if the board supports a given CPU or not. And if so, whether or not it needs a BIOS update to do so.

But at 1280x720, the HD 6870 is probably more card than you need. It will defenitly be able to max out any game's settings at that resolution. Even an HD 7750 can game great at 1280x720: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007709%20600286767%20600298541&IsNodeId=1&bop=And&Order=PRICE&PageSize=20
And it can do it without the need for a very big PSU. What size PSU do you have now?

Seasonic makes good PSUs. Although I've never seen one of their "Eco series". Sounds low end. Their "Super Versatile" series is only rated one tier above the 'not recommended' 4th tier. Perhaps you could post a link to the eco 500w.

Again, it is important to list the rest of your system for a better evaluation. Or at least use a PSU calculator to judge for yourself what you need:

the model for seasonic is ss500bt
you can find it in here http://www.seasonic.com/product/pc_atx_1000330.jsp
there is also this psu that i can get
HEC (Gamma) 600w atx 12v v.2.3
i know that they are low end psu but that is what available for me.
"Again, it is important to list the rest of your system for a better evaluation"
actually any psu will do fine for now, it's just that i want good psu so when i replace the cpu\gpu there would be no problem
