Enriched RTX 3090 Ti SuprimX PCB breakdown notes (Patreon)

This is my favorite of the normie 3090Ti PCBs. I consider it a normie 3090Ti since it only has 1 16pin connector unlike the HOF and KPE which have 2. Also the 16pin can handle less power than 3x 8pins. However retroactively increasing the power spec of 8pins to better match their physical limits is not a good idea so now we have the 16pin with it's 600W power limit(which is pretty close to it's physical limit).Extra FeaturesDual BIOS20A Fuses on all 12V inputs. In the event of a VRM failure(rather unlikely with VRMs like these) these can make any repair attempt much easier2x UPi Semi US5650 for shunt monitoring

Vcore VRMLAYOUT24 SPSs in total. 12 on each side of the GPU core to reduce power plane impedance.CONTROLLER: Monolithic Power Systems MP2891 assumed to be in 12+4 phase mode since it's a 16phase controller and Vcore has 24 SPSs while Vmem has 4. (+4 is for mem)

MOSFETS: Monolithic Power Systems MP86957 70A SPS

MOSFET EFFICIENCY:400A ~29W (the Vcore and MSVDD on a ref 3090 would do ~47W)500A ~39W (the Vcore and MSVDD on a ref 3090 would do ~70W)600A ~50W800A ~77W1000A ~108W

This Vcore VRM is stronger than even the best RTX 3090s:HOF 3090 is 14+8 70A SPSKPE 3090 is 13+6 60A SPSStrix 3090 is 12+6 60A SPSVCORE FILTERING:220nH inductors (normal for 3090/3090Ti)48x 2 terminal 220uF molded SMD aluminium polymer capacitors (FE has 40x 220uF)

Memory VRMLAYOUT4 SPS in total 1 at each corner of the memory power plane to improve impedance.
