The main distinction between H-series and B-series motherboards is often cited as features, but not the quality of components. I experienced two old H61 boards failing within a couple of years, showing random restarts and damaged power ICs. After looking online, I discovered this problem was widespread in older H-series boards. Nowadays, such issues seem rare on budget models. Does this suggest manufacturers now use better parts in all their products?
Affordable boards feature straightforward PCBs that are typically smaller than standard designs. They have fewer layers, cheaper parts, and weaker or smaller VRMs. The design isn't influenced by the chipset; some Z-series boards are more budget-friendly than certain B-series models.
There are variations in the motherboards between B660 and H670 for VRM quality. Some models are quite poor (B660M-HDV), others are acceptable (H670 PG Riptide), and a few perform reasonably well (B660M-A Pro). The improvement over the past five years stems from the fact that custom PC builders now often choose B- and H-series chipsets instead of sticking with the Z-series. Overclocking is no longer popular, Z-series boards have become much more expensive, prompting users to prioritize cost savings while sacrificing some features. Additionally, B-series boards are now priced similarly to most Z-series models from five years ago, making them a more affordable option with comparable components.
They'll opt for more affordable MOSFETs or power stages, possibly adding extra units in parallel. Replacing a $2 power stage with two $0.25 lower-quality MOSFETs is still cheaper, even though these are less efficient and generate more heat. They'll reduce heatsink usage—avoiding aluminum and copper increases costs and weight, which raises shipping expenses. They'll choose cheaper capacitors, such as a $0.10 rated for 2k hours at 105°C versus a $0.15 rated for 5k hours at the same temperature. They'll switch to 4-layer boards instead of 6/8 layers, limit RAM slots to cut costs, and hide the fact that lower-quality circuit boards may hinder 4-input usage at high frequencies. Sometimes they'll remove HDMI connectors from the back and switch to DVI or DisplayPort, saving on licensing fees.
I noticed that video showing the hardware being unboxed for the top B660 motherboard. I hope they also improved the design for the best H610 board too. After all, there’s nothing truly exceptional about them, right?
