  1. Depending on the brand of the psu it may work, but it'll be a stretch. If you have a cheap brand of psu, I can tell you now it will not work well

    sorry it seems you gave some incorrect info, the 650ti only need 20A and a min 400W psu

    so if you have a 450W with 36A it should work.

    yes I will work. Most likely it is a typo, since a gtx 770 requires 42A.

    your ASUS 650ti OC has a tdp of 140W which when divided by 12v, gives about 12A
    but the 770 has a tdp of 230W which when divided by 12v, gives about 20A, therefore, since I know as a fact the 770 needs 42A, and the 650Ti requires 8A less then it, it should require 34A at MOST.

    Also it doesn't make sense to recommend a 400W psu with 38A since NO 400W psu ever invented will have anywhere near 38A.

    Yes it should work with your psu, but if you can I would upgrade your psu just so your not putting too much strain on your psu. Its never good to run your psu at near 100% capacity.

    and If you don't believe me that it could be a typo on their box, and it in fact requires 38A, it will NOT work with your PSU since your psu can only deliver 36A.
