is ASUS Z77-A motherboard fine for ocing i5 2500k to 4.3ghz?

I don't know if you have gotten an answer yet... but I just bought the Asus z77-a when my P8P67 pro 3.1 quit on me (in for RMA now), and I have my i5-2500k at 4.3 stable on it now at 1.36v. That's only 0.1 ghz lower than what it would do on the P8P67 at the same voltage. It's not a great 2500k.
1.36v is a safe voltage, and it will OC to 4.3 even with a poor 2500k like mine, so you should be in good shape.

SR-71, I think the OP means that his ASrock z77 Extreme 4 stopped working and he wants to know how good the Asus z77-a will be as a replacement. I am in the same situation with my P8P67 having just quit, and Fry's Electronics (the only local place I have found with motherboards at reasonable prices) only has the Asus z77-A and a similarly low end MSI board in socket 1155.
Since I am overclocking, the Asus seems like the easy choice between the two boards described. The MSI doesn't have heat sinks on the VRM transistors (also 4 cpu phases), not to mention that MSI boards have quite a history of burning out VRMs because they lack overcurrent protection (not sure whether or not this model also lacks that feature, though). The Z77-A has overcurrent protection, which seems especially important given its relatively low-end VRM.
The Asus z77-a has almost as many OC options in the UEFI as my P8P67, so it is able to overclock... but with only 4 CPU power phases, it is more of a mainstream/budget board than a true OC board. That's my guess as to why it won't get my i5-2500 beyond 4.3 (@1.36v loaded) where my P8P67 got it to 4.4 at the same voltage. I think that getting within 1000 mhz of a 12 phase board is pretty impressive for a measly 4 phase (only talking about the CPU here, not the RAM and onboard video phases) board, though.
