Thanks to Irma my PC needs fixing. The power supply for sure is shot all my PC does is start and shut down in seconds of being on. And not sure of which one I need. I have a Corsair tx 750 enthusiest power supply ATM and would like a better one since I do a lot of gaming on it but I fear I may need a motherboard too . The board is a Asus z77 extreme 4 and chip is a Intel i7 3770 all of which may need replacing but I wanna start with the power supply for sure. This is going in a phantom 410 and I need the power supply for a micro atx.
