Normally the specifications for cards, found on the vendor site or at the manufacturer's website, will list the power requirements. You also might want to become familiar with a free tool for evaluating the power needs of your entire system:
When i bought it i did not have the knowledge how things are with it(2 years ago) and it locked pretty good to me at that time.
What would you suggest to by in the near future? Not too pricey but ok for mainstream video cards(no sli or crossfire).
If I were buying one today, I would get the OCZ ModXStream Pro 500W at $65 - $25 mail in rebate = $40 + $10 shipping = $50. Its decent quality and low price have made it a good deal for at least several months now. If it did not have the rebate, though, I would probably try to find another good PSU on sale.
Hi guys, sorry for this late reply, I've bean a little busy.
OCZ and Corsair sound good, OCZ has more amps but 2 rails wile corsair has only 1 rail. I don't have newegg in my country so i will have to buy from another online store one of those power supply's. I will also check that list with power supply classification that rockyjohn give me in the near future and see witch i will find more suitable if those two are unavailable.
