Como te veo muy perdido sobre el tema, ya podria informar el personal sobre el famoso tema de los VRM en las z370/z390
Right now it's looking like for VRM (subject to change if some boards are using 2 low side mosfets aka "doubled low side"):
TOP (LN2 , monoblocks)= Gigabyte Z370 SOC Force (unreleased, found on hwbot records) , Gigabyte Z370 Gaming 7 due to iSL99227B (60A rating) ... top audio, overkill VRM , Asus ROG APEX (a record holder on LN2) using 50A Optimos, MSI Z370 Godlike (using 60A IR3555 overkill VRM poor price/perf regardless)... likely Asus Z370 Maximus X Extreme too
Upper tier (custom water) = Asrock Z370 Fatal1ty Gaming Pro i7 (
whatever the full name is, the expensive one) , Asrock Z370 Taichi using Fairchild Dual-N (low+high side) when heatsinked properly with heatpipe (limited to about 35A per mosfet @ 100°C), Asus Formula/Code/Hero boards using 50A Optimos
Midrange <$200 (All-in-one watercooling/dual tower air cooling)= Asrock Z370 Extreme4 / K6 using Sinopower 2-in-1 / "DSM"/ low+high side
Low Midrange , should be $160ish or less (Asus z270-A level VRM)=Asus Z370-A , Asus Z370E/F /G , Gigabyte Z370 Gaming 5 , MSI Z370 Pro carbon , MSI z370 M5
Entry (sub 150W probably / 120mm fan cooler level, should be $120 or less if VRM is the only concern) = Asrock Z370 Killer SLI (push pin heatsink , cut down features is another issue on top of regular Sinopowers) , MSI z370 SLI PLUS (uPi controller + Ubiq mosfets) , MSI Z370 Krait (uPi controller + Ubiq mosfets) , MSI Z370 Tomahawk (uPi controller + Ubiq mosfets ; ALC892)
Not suitable for really overclocking unless it's not an i7 (at best MCE/ multi-core turbo only) = Asus TUF Pro Gaming / z370 STRIX H, Gigabyte Z370 Ultra Gaming , Gigabyte Z370 Gaming 3 & K3, Gigabyte Z370 XP SLI, MSI Z370 Gaming Plus, etc
<4 phases , or partially Unheatsinked (don't buy) :Asus Z370-P / TUF Z370 Plus, MSI Z370-A Pro , MSI z370 PC Pro, Asrock Z370 Pro4 , Gigabyte Z370 HD3, Gigabyte Z370M D3H , etc
* Be advised the
Taichi has a very good memory VRM capable of 4333MHz+ RAM speeds , on par with ASUS ROG APEX. The highest QVL on the
Gigabyte Gaming 7 and
MSI Godlike are 4133MHz.
