yeah that might be right...bt buying a new psu shall be very expensive for me...y not on this psu..?? wat if i plug those AMD card that u have mentioned on my current PSU..??if they require such low power..?
your current power supply can't deliver it's rated power... but it has over power protection. Yes, the cards I recommended are low power and won't stress your psu much. you can probably get away with your current psu as a "transition" stage until you save up more money, but given that your PSU has over power protection, issues with your previous card isn't caused by drawing too much power from your PSU. thus, either it was time for your old card to die, or your PSU is going bad. in the ladder case, better change the PSU before it really blows
the antec looniam recommended's an excellent brand at a great price.
