    Housing construction isn’t funded by existing housing investment. It’s generally funded by debt. Private or public, just like any other capital intensive endeavor. And debt isn’t created by lending people’s savings but by creating new money. By public or private lenders. (Private lenders create money too.) The only thing that is really needed ahead of time is labor, equipment and materials available. Financial capital is created on demand to mobilize those real resources.









  • TBH, this is a risk for all “value” devices that don’t have to pass NA/EU electrical certification. No cert means the cell can be whatever part was cheap and alright enough. Longer term reliability without specific testing isn’t obvious. Every now and then I fall into the rabbit hole of trying to remember all the different devices with potentially questionable cells. The occasion today is likely to trigger another sweep.

    While true for the component itself, there’s material difference for any caps surrounding it. Sure the chipset would work fine at 40, 50, 70°C. However electrolytic capacitors lifespan is halved with every 10°C temperature increase. From a brief search it seems solid caps also crap out much faster at higher temps but can outlast electrolytic at lower temps. This is a consideration for a long lifespan system. The one in my case is expected to operate till 2032 or beyond.

    I don’t think other components degrade in any significant fashion whether they run at 40 or 60°C.






  • So generally Pegatron. :D I used to buy GB because it was made in Taiwan when ASUS became Pegatron and went to China. Their quality decreased. GB used to put high quality components on their boards in comparison. But now GB is also made somewhere in the PRC. I’ve no idea where MSI are in terms of quality. We used to make fun of them using the worst capacitors back in the 90s/00s. Looking at their Newegg reviews, their 1-star ratings seem lower proportion compared to Pegatron brands and GB. Maybe they’re nicer these days? The X570 replacement I got for this machine is an ASUS - “TUF” 🙄
