I have a seasonic s12ii psu that i am planning to use on a system running a i5 4th gen(haswell)cpu.

However i have heard that this psu doesn't support something called haswell's sleep states-could that possibly cause any performance or stability issues if this power supply is used with such a system?

Would disabling the sleep states from the bios prevent any further problems from occurring?In particular which sleep state should i disable to achieve this?(the motherboard that i am using has 3 of them,namely c1,c3 and c6/c7-is the last setting the one that needs to be disabled,or should i just disable all of them at once?)

thanks for confirming this-i will be disabling c6/c7 states after installing this psu-by default they seem to be on "auto".The board itself is a Gigabyte b85 m d3h A
