Analysis of VRM Quality on Z87 (Starting with mine) - Page 5

post #41 of 161
yea 5930AL and and 9130AL, but notice how you have NXP LF-PAKs but the guy who started it has got some renesas powerpaks. They are pretty equal tho in performance, maybe early batches had one kind and later had another and that is why i can't find many shots.

i appreciate it, i guess I will make two listings for the Z87 Extreme4 then, both sets of MOSFETs are much better than the Z77 Extreme4 and both are about equivalent, both packages can handle a decent amount of current, it must be a supply thing.

Oh no when i said different I meant the MOSFETs, notice they are different than yours.

But yea the 1.0uH inductors are the same, thank you smile.gif

Looking at the ASRock Z87 Extreme4-M, it looks like D-PAK MOSFETs isn't it?

yea it is, on at least one mid range board asrock always manages to put in d-pak MOSFETs
