i have a Liteon PS-6301-08A 300watt PSu
i want to replace it with a more powerful psu (recommend pls) to run my zotac GTX 750ti.

below is my spec

WINDOWS 8
Intel Core i7 processor 3770
nVidia GeForce GT640 4GB OEM
1TB Hard Drive
8GB DDR3 memory
DVD-Super Multi drive
Card Reader

2 fans , one for the cpu and other one is for computer case

I haven think of any brand to choose so what model should i buy ? what psu size will fit my case (although i open my case but i still don't know the dimensions of my psu) what will happen if i put a too big or small psu in my case ?

Ps : I live in malaysia.
