Need help with my psu and gtx 660 ti

[oddjtheanimator]

Hey guys,
I’ve been having tdr issues with my galaxy gtx 660 ti 3gb and I think my psu is the answer, it’s 460w and the 12v rating is much less than the minimum. So I got a thermaltake tr2 rx 550w and the 12v rating is 19A, my graphics cards minimum is 24A, please tell me if this is alright, as I would hate to have got something that was $55 and is no use to me.

16A alone is not enough. Your new PSU does have 2 12V rails, the other one is 17A. Still not a very good PSU.

Best advice is to buy a good quality PSU.
