I will be Gaming a lot with my HD 6870 can be even more than 5hours, so i want to get a good PSU but i dont want to pay extra. I just want a budget one, and i have No plans for CFX.

Solution
500W IS enough. Btw make sure with those links i gave that there is enough ventilation room in your case. Sometimes psu are placed completely in the top of the system and the fans are on the top of the psu, so watch that.

My club3d 6870 runs on a Corsair cx430 v2. I'm also using a i3 2100.

It works well and all, but I'll recommend something with a bit more beef.

See if you can find a cx500.

Sort of, but I haven't played like 5 hours straight. When you play that long it will probably get a bit warm. If you really want to same some money, then get it.

Other readers here may have more experience with the cx430.

I did the same thing, I was not ready to pay some extra bucks on PSU, I got a 550watt.
After that installation, my gpu gtx 460 ran fine for some weeks.
When Games became more demanding, i needed more power out of it. So it would need more wattage of course.
Now I installed a 650watt PSU, n yes, everything's good now.

Thats why I would suggest you to go for minimum 600watt PSU.
Because even if 550 watt works fine on the edge, after some time, you will need to, for e.g. add some RAM, HDD, or in case if u change a processor, got a higher one, you'll need to change the PSU again. It'll be a waste of money.
So its better to go for 20% extra money, than to buy a whole new one after your needs increase..!!
Minimum 550 watt
Recommended 600 watt.
Cheers..!!

Some questions, are you using only one graphx card? or planning for dual gpu?
how many hard drives you have?
any additional PCI/PCI-e cards?
how many optical drives?
And about HDD's, are they 7200 rpm, or higher, or lower??

I have NO plan for CrossfireX as i have metioned before.

1x 7200 SATA HDD
1x ODD, and NO additional PCI E X16.
Now what?

Now according to my Calculations, you will need minimum 382 to 401 watts. But to be on safer side, I would suggest you to go for minimum 450watt or 500watt will do just great.
I am shocked to see that results though..!!

See man, my Case has 4x 120mm fans. And i dont want to get into any problem after getting a 500W PSU for saving a few bucks. If its needed then i will pay for a 600W, which will be difficult for sure but better than problems i face later. And its really becomes hard to make a decision when different people come with different suggestions.

I dont know whats wrong with you guys, a GTX 460 requires a bit less or same as HD 6870. If you have faced then i may also face. And one of friend runs GTX 460 with FSP SAGA II 500 with no issues! Shocked Again?

Dude, I have 3 X 1TB's 7200rpm HDD's, + 2 Optical drives( one dvdrw and one Blu ray), + some LED's inside my case to lighten it up. It takes more than 500 watt even if I have a GTX 460.
Moreover, corei7 might take a little bit more than core i3, also I have got an SLI motherboard. SO thats why I needed 650watt PSU..!!
Yours is OK, more than OK for 500 watt, just go for Coolermaster..!!
