Wow almost 24 minutes of bla bla. And a number of I Think, I assume, I don't know, I don't know what it's for, I don't know why they build it like this. But he doesn't answer the big question, is it suitable for the purpose, and it's not the first time he does this. If a board is bad, it's bad, if it suits the purpuse, even if you don't like the design choises, it's good. I have seen many motherboards being roasted by him blattetring on about VRM's, always skipping the big question, is it good for what it has been designed for. Anyone who buys a system with this board, knows up front it's not designed for overclocking, why bother to discuss its misisng overclock potential, just tell if the board dioes, what it is built for, and if it has enough headroom, to do so for years. Personally i wouldn't take him serious. Think for yourselve, and not just accept what god buildzoid, or der8auer telling, because honestly it's often a load of crap

G'day Buildzoid & Steve, although not a Standalone Purchase M/B thanks for the rundown on the specs, it is very interesting to see where the PreBuilt companies cut costs for making a comparison to buying the parts for your own build in the same price range, Buildzoid said this is a 4 Layer PCB, would this have any impact on the Quality & performane of PCIe Gen4 later in life, as from memory (not very good most of the time) in the X570 M/B some reviewers said there was a need for better Quality & thus more layers of the PCB for PCIe Gen4 as a reason for the increased cost & why AMD didn't allow compatibility with B450, I also noticed the 2 PCIeX16 Slots & AMD Crossfire Logo, I wonder how many CyberPower PC will come with 2 GPUs

Nobody is going to overclock this. Ohh yes they are. If you're buying a budget pre-built gaming PC chances are you wanted more for your money, and there is one way to get more performance without spending more money. Doesn't mean you're going to have great success on a board like this, but you'll try. I did on my first gaming PC from Cyberpower. But there are other things than cost that factor in to Cyberpower's board layout decisions such as Do we want to deal with an increased number of RMA's and service calls for this model or If people can buy the 3600x model and overclock it to perform like a 3700x, is that going to cannibalize our sales of the next highest priced model?

PCEI 4. 0 support is the least of my concern, it's ram support speed I concern about. I just want to know whether an actual B550 will support DDR4 3200 MHz+ without the need for overclocking. B450 was disappointing that it capped at 2933Mhz, I mean really? Why not capped at 3000? What bogus is that? 3200 MHz seems to be the sweet spot, especially for Ryzen build which provides a bit of better performance. When B550 comes out and doesn't deliver, I guess I have to settle on the expensive x570.

Nice analysis. But might be worth checking if the build cost savings are passed on to the consumer in a meaningful way. Simple summary contrasting this board with higher spec alternatives, but briefly examine the correlation with price. Personally, I rarely o/c unless there is a pronounced bottleneck that justifies it. Any chance you could expand on power tolerances for the ram too? In terms of longevity and long term energy savings: ) Nice video. Thanks!

The MOSFETs have 10+14 nC of gate charge (at 4. 5V gate drive) so at 700 kHz swtiching frequency, they take 17mA 4. 5V=75 mW per phase to run. That's not too bad, and likely due to the relatively high RDSon. MOSFETs with lower RDSon have much worse gate charge. For lower current applications you can easily lose more power on gate charge than RDSon. Unfortunately as you see here, that's only true for currents far lower than a normal CPU will pull: /

Buildzoid is genuinely underestimating people these days, some people push 1. 5v on their 3rd gen ryzens without anyone else knowing about it and you think people will not overclock AT ALL? To keep people from overclocking, you need to lock down the chipset and cpus, like intel ones, otherwise people are bound to mess around with things based on things they read online.

Nobody is going to overclock on it. You are underestimating kids, their parents might buy a PC like that and when the kid hears about overcloking he is going to try it. When I was young I overclocked my parents Compaq Pentium 120 MHz (2x60MHz) to 165 MHz (3x55MHz, 2. 5x66MHz crashed right away) by randomly testing different jumper configurations on the motherboard.

People think they do need PCIE 4. 0 - but they don't. Typical user will not take advantage of having PCIE 4. 0 throughout life span of the system. GPUs are far from capping PCIE 3. 0 x16 lanes and NVME Gen4 is useless even in comparison to SATA3 SSD in absolute majority of daily use read/write operations (which are not big file size sequential.

Why do you think no-one's going to overclock on this? People are going to overclock on it. Not most of them, but many of them will. Just because people shouldn't overclock on it doesn't mean they won't overclock on it. If they undervolt a bit and/or if they're only on a 3600, they're still likely to have a bit of safe overclocking headroom.
