Haswell psu problem

I'm thinking of purchasing a MSI z87 G45 mobo. For the cpu a 4670k...this is haswell..and there may be a problem. My current psu is a OCZ modxstream 700w. Its not on the haswell compatibility list. I know you can disable sleep states in bios or the os but i'm switching from amd and i need to do a clean install. How can i access the bios if i have to install a fresh windows install first? I heard people not being able to POST. If i cant even post (idk if i will or not be able to) how will i access my bios?

More about haswell psu problem
  1. the sleep state is only when the pc goes to sleep so should not be an issue when first booting up and u dont need windows to boot into bios either and if the psu cant handle the sleep state it just goes into a different one that the psu can handle
  2. You don't need to have an OS installed to access the UEFI settings (BIOS is almost universally depreciated on all 6, 7, and 8 series motherboards). Just press DEL/F2/F10 on startup.

    With that said, the OCZ ModXStreme PSUs are garbage. The new Seasonic G series are Haswell ready at a great price.

    But don't you need to install bios? My pc is going to have nothing on it.

    Nope. The firmware (BIOS on older computers, UEFI on new computers) ships with the motherboard.

    So after I yank out my old mobo and cpu, install the new mobo and cpu. Power it up, what will I see?

    You'll see the POST, followed by it attempting to find a boot device
