Hello,

I'm a bit worried. I noticed that I ordered PSU that's not compatible with my CPU.

Specs:
ASUS Z87-PRO
INTEL Core i5-4670K
Seasonic S12II-620W

Now when I'm waiting for my package I saw that my PSU is not Haswell ready. Should I be worried? Would it run good anyway, just sleep option will not work?

Thanks in advance

Don't worry , you can just disable the C-States in the BIOS, this may not even be an issue though.Many people have reported no issues with the C- States.

Nice PSU choice

The C states are a low power/idle feature that just saves power when the CPU is idle. The only issue with older PSU's is that they aren't able to deliver stable voltages at that level and thus activate protections which result in you having to turn your PSU on and off.

It would cause no harm to your system but would obviously be annoying. To prevent it you can just turn off the C states in the bios so that issue never occurs. That way you can carry on using your old PSU.

you don't, strictly speaking, need one of these "Haswell-ready" PSUs to build a Haswell system. Corsair told us that it "fully expects" motherboard makers to let users disable the new low-power power state in the firmware. Cooler Master went even further, stating that, to its knowledge, "all mainboard vendors" will disable the new low-power state in their boards by default. In other words, you may never encounter any issues even if you pair a Haswell platform with an incompatible power supply.


And that psu would be fine
