GIGABYTE is ready with two Aorus branded motherboards based on the upcoming AMD B450 mid-range socket AM4 chipset. These include the B450 Aorus Pro in the ATX form-factor, and the micro-ATX B450 Aorus M. The B450 Aorus Pro packs many of the features you'd expect from a more expensive board based on the pricier X470 chipset. The board draws power from a combination of 24-pin ATX and 8-pin EPS connectors, conditioning it for the AM4 SoC using a 11-phase VRM with high-current chokes. The AM4 SoC is wired to four DDR4 DIMM slots, and the board's sole reinforced PCI-Express 3.0 x16 slot. The second x16 slot is physically gen 3.0 x4 and shares its lanes with the top M.2-22110 slot; which is wired directly to the AM4 SoC. With an M.2 SSD installed, auto-switching gates the second x16 AIC slot. The third x16 slot is gen 2.0 x4, and wired to the chipset. The second M.2-2280 slot is gen 2.0 x4, too. A single PCIe x1 slot makes for the rest of the expansion.

Both M.2 slots on the B450 Aorus Pro feature heatsinks. Six SATA 6 Gbps ports, from which two come from the AM4 SoC, make for the rest of the storage connectivity. As part of the "gamer-grade" varnishing, this board gets rather high-end onboard audio, including a Realtek ALC1220 (120 dBA SNR) codec with EMI shielding, audio-grade WIMA and Muse capacitors, and ground layer isolation. USB connectivity includes two USB 3.1 type 2 ports (one each of type-A and type-C); and six USB 3.1 gen 1 (four on the rear panel, two by headers). Display outputs include DVI and HDMI. The sole networking connectivity is a 1 GbE interface. Its controller is unknown. You get RGB LED illumination and headers, and an integrated rear I/O shield.



Next up, is the B450 Aorus M. This board maxes out the micro-ATX form-factor at 250 mm x 250 mm PCB dimensions. This board has a similar power-delivery setup to its ATX sibling, including the 11-phase SoC VRM, with the exception of a heatsink over the SoC power phases (not that they badly need one unless powering an APU with an overclocked iGPU). There's just the one M.2-22110 slot on this board, and like the B450 Aorus Pro, it has auto-switching with the second PCI-Express 3.0 x16 (electrical gen 3.0 x4) slot. The rest of its storage connectivity is identical. The onboard audio solution is slightly slimmer. This board has slightly more legacy connectivity, including a PS/2 combo port on the rear panel, and LPT/COM headers. USB connectivity is the same, although there's no type-C port.

Those are some solid looking boards. I must say.
Seem to carry 4+2 phase, possible for VRM system. Eh, decent enough for 4-6C part OC

They both seem to have 11 chokes unless I'm counting wrong.... blows me away, considering it's a b450....

Now that I actually read some of it, they both, indeed, have 11.

No Type-C and DP conector. :mad::mad::mad::mad:. Their Intel 300 series motherboard has those.

Obviously "B450 Aorus M" has 4+3 phases and one of CPU phases has no heatsink.
CPU: 4x (1xHi 2xLo 2xCoil). Energy efficient design doubles low mosfet and coil count to minimize resistance and loses.
SOC: 3x (1xHi 1xLo 1xCoil)

Ah, yeah, I'm noticing that now... thanks. Still, it would be a killer upgrade path for my mom's mATX case. She's using an old Athlon II x2 and it's running Angry Birds on facebook painfully slow. Plus she can barely troll the newbs and discover new memes quickly enough.

Be careful, they could have doublers

That is correct. The M version is worrying, it doesn't have heatsink for SoC VRM section. People who opt for mATX usually coupled them with an APU to make a decent home theater/budget gaming PC. iGPU gets their power from those VRM section.

:clap: at last, B450 is out, even if listed on US site. B450M DS3H up for viewing Link

I been listening at actually hardcore on youtube about board breakdowns.

4+3 VRM
4 real phases
4 fake
3 SoC
I am almost sure there will not be dublers here, because Gigabyte does not use doublers until like 250Eur for MB.
They are using shitty mosfets and thats the reason why they 'have' to double the component count for each of the real phases.
They may be ok for an 8C@Stock.

Doublers is the wrong term used here. These will probably be splitters, dividing the frequency to the VRMs.
Its an OK solution for some budget boards
