I'm talking with the scientific facts here. DPAK mosfets are unreliable. That's why it's out of industry years ago. None of the electronic manufacturers are using them anymore (even most of the chinese noname electronic companies) But ASRock managed to use them even in their mid-range boards somehow until today. It seems like they start following the industrial facts now thoughi they haven't used dpaks on 9 series boards. Glad they haven't hired you as an engineer.
But I agree you about QC, support, good design etc... But before buying a product, a normal person first look at the "quality" of the components. Then comes the QC and support. But sadly ASRock Z77 Extreme 4 fails to pass the first test here. If someone wants to pay money for inferior products or has a weird taste of getting robbed it's another story and I won't argue personal tastes.
But using dpak mosfets, making deceptive marketing about "gold" capacitors (which are actually some generic 2k solid caps painted yellow) and promoting hybrid/analog controllers as digital vrm is just unaccaptable. Defending these stuff is even more unaccaptable.
They took their lesson though. Now at least they upped the quality of mosfets and capacitors. Which proves me right about their previous quality. But they still doing some deceptive marketing.
Glad we have many options on the shelves today and people are not stuck with some bad quality stuff.
