Hello.

This is my first question on this community.
2 days ago, my videocard GT 8600 died. I made the choice to buy a new one in a store that is close to where i live.
I think i made mistake with the PSU, and i really hope it is not a huge problem.

I bought a GT 440 1024MB DDR3 PCI-E 2.0.
I also bought with it at the same store a PSU: 370 W PSU big fan.
PSU info:
+3.3V, +5V, +12V, -12V, +5V
14A, 30A, 15A, 0.8A, 2A
180W, 180W, 12W, 10W

Now i replaced my own old PSU for the first time, and it went well!
I now sometimes have problem starting the computer, and i had to start it with my OnBoard videocard a few times to delete some drivers. Now i tried some gaming, like kingdom of amalur, counterstrike, blades of time, it all works perfect except for 1 game, the game i played the most and i love the most, has stopped working.
This game is might and magic heroes VI. When i open the game, the screen shuts itself down for 2-3 seconds, and then i have to close the game with ctrl-alt-del. Then a message appears that the driver display has stopped and recovered with an error on a file named: nvlddmkm. Now i have searched some info, and i found that this is being caused by TDR. It only affects this game i love th most. When i look at the package of my GT 440 it says it needs a minimum of 300W PSU, and i have bought 370W. The problem i saw next was that the GT 440 says it needs 22 Amps on the +12V rail. However, my PSU has only 15 Amps instead of 22 Amps on the +12V rail. Can this be the problem why might and magic isnt working? Is the videocard to much for this PSU i bought?
Can this problem be fixed if i buy a better PSU with minimum 22 Amps on the +12v rail ? It is my first time so i dont know much about PSU. I hope u can help me guys. If u need some more info, i will do my best to provide it.

Why would you think it could run on something that doesnt meet the MINIMUM requirements? Im guessing the PSU is also probably not a very good one. Next time buy what you are supposed to and dont make your PSU your biggest budget purchase.

Well i saw it after i bought it. I only looked at the minimum Watt, not the minimum Amps needed on that trail, as it was my first time. The store wont give me my money back, but i can go back and exchange it for another one. If i add some more money i can get a better one. So all i need to do is buy a better PSU then with a minimum of 22 Amps ? I would also like to know if it is bad for my computer if i play the games that i mentioned above, even thou they work fine, if i dont meet the minimum Amps ?
Is it bad even if i turn on my computer while i dont have the minimum Amps ?
Thank you very much for helping me out!
