Dope Tech Episode 2

<<@BPEMETO says : Hi! : ) Is it possible playing a game can make your power supply start smoking and break? Can it overload it somehow and lead to that outcome? It happened one time while I was playing a certain game and then months later with a new supply playing the exact same game ...>> <<@yogibear2k2 says : Sorry, I know this is one of your older videos, but it did make me smile when you said molex is still sadly used. Personally, I prefer molex over SATA, but then, I have been told I am a little weird. 😅 But a very interesting video. Than you.>> <<@mirrlamp says : Thank you! That cleared up a lot of questions I had about pc power supplies.>> <<@BOplaid says : Which PSU brand(s) do you recommend?>> <<@robertomaximilianosilveira8768 says : Nice to see this excelent video>> <<@JonDeth says : They also provide very noisy, dirty D.C. and all the folks who think they will use one for their journey into DIY electronics are in for a lot of misery lol! *Your desktop's motherboard has so many filter caps on it that it doesn't suffer from the dirty power, but anything analog and entry level you look to run off them will either run terribly or they won't even power on.*>> <<@keithcitizen4855 says : Proprietary plug set ups something else EG HP computers I bodged in substituted a PSU that did not have minus 12 volts , my old XP used it just in the power up section , I made an external legacy circuit to do the same thing instead of having power on permanently hard wired on all the time.>> <<@215Days says : The explanation regarding 80 Plus was top notch, it made me very easily understand what that term is now, it makes me want to get a Titanium PSU. Excessively well done as always, Mister Barnatt!>> <<@Tom_Quixote says : Very good refresher for me. Last time I built a PC was in 1994, so a lot of things have changed since then.>> <<@levine933 says : Thank you, you saved me.>> <<@TapesNstuffS says : A pet peeve of mine is the use of a redundant ".0" at the end of a number since there is almost never a decimal grade update. Why not say windows 11.00_0 at this point?>> <<@lideruploader6577 says : EC always saves the PC noobs like me, thank you so much. 😌>> <<@LenaReginald says : 08718 Carissa Knoll>> <<@benwhite3703 says : 991 Zemlak Extension>> <<@poppiescarter9720 says : 4637 Filiberto Isle>> <<@tunkunrunk says : now I can put a name on power supplies and motherboards power connectors I wasn't familiar with , Thanks a lot Sir, your English is easy to understand , I speak French , Merci beaucoup Monsieur>> <<@RogerAntonio-m7e says : 823 Lambert Fork>> <<@mikezzz7885 says : The Scotty Kilmer of PCs !>> <<@michaelcroftoon5509 says : 015 Bernhard Club>> <<@MatthewCyril-i7z says : 1519 Clementina Stravenue>> <<@RicardoBelle-p2d says : 0410 Mraz Lane>> <<@TurnerMaurice says : 587 Hand Turnpike>> <<@Johnny-Taylor-07 says : I love your sexy eyes !!>> <<@HughCarl says : 016 Turner Manors>> <<@vixbrabec says : thanks man you helped me>> <<@dPten says : You forgot to mention one crucial aspect of PSUs. Their hold up time, which many brands like MSI do not find necessary to put out in the product specifications. It is also a measure of how good the capacitors are.>> <<@feridbuljugic says : Ah! A battery can also be used to power the PC, Letting the PSU charge it makes it uninterruptible.>> <<@leo_craft1 says : So sad they dropped the tx series>> <<@gregorydayton5428 says : This was a great video. I learned so much. I have been building PC's for ten years and never thought much about PSU's.>> <<@katleencuchapin3037 says : Can someone help me here please 🙏🙏 I'm a grade 11 student and we have assignment about computer parts and I can't find the answer in Google! Here's my assignment Name of PSU 1. 20+4 Pin 4pin 2. 20+4 Pin 4Pin Molex Sata 3. 20+4 Pin 4Pin 6Pin Molex SatA Please can someone answer me🙏🙏>> <<@BenKlassen1 says : Great!>> <<@l0gic23 says : Wonders if swapping PSU for old desktops will help homelab cost savings>> <<@thomasmcguire2227 says : Thanks! I finally got around to replacing my old 300W PSU with a 550W but had to use an adapter since the 550W only had a 24 pin power connector.>> <<@MobileBeanie says : This is great information! I've been trying to learn about building a pc for the last couple of months and nobody talks about what power supply you should be running based on the usage. This was what I was mostly after, but also knowing that the sustained and peak supply rating is different but labeled the same across different manufacturers is good to know as well.>> <<@Castropc says : Another interesting topic explained. Not 100% connected to this video but is it better to turn off your PC or sleep or hibernate it when you are not going to be using it for a while?>> <<@clair9167 says : Such a good training! So well explained.>> <<@harryniedecken5321 says : Thank you for the video. I am rebuilding up an atx desktop which will be used off grid. Power will come from solar plus a 48 VDC nominal battery pack. Does anyone make an atx power supply that can run directly from the battery pack dc ? Thank you.>> <<@todortodorov8651 says : Spectacular video. I based one whole lecture on PSUs for the highschool I am teaching at, based on your video. Bowing down at your skill to explain and organize, we know how much time it took to prepare so much information.>> <<@j7ndominica051 says : Why do PSUs now boast single rail 12V with a "DC-to-DC" converter? You can see on the specs sheet that the PSU promises its full wattage at 12V. What new technology enables it as a better design? Aren't voltage regulators kind of bad and dissipate a lot of heat in battery operated devices? Seems like they snuck the 12V Only into ATX. When 12VO came out, there were rumors that this power supply would be the only one in production thus rendering old PCs obsolete if their PSU could not be replaced. They also have removed 3.3V from the SATA connector, which was almost never used. The 8 pin CPU connector fits into a 4 pin socket if there are no tall components nearby. 500W seems like the goldilocks choice, offered at similar price than lower wattages. Back in the P4 days I bought a cheap power supply that claimed to be silent, and indeed its fan hardly turned, the PSU was noticeably warm to the touch and soon burned out.>> <<@Blazer433 says : I love your channel, so informative>> <<@sativagirl1885 says : Q: Why not design a power supply that's the same footprint of a raspberry pi SBC. and eliminate messy cables that Mister Scissors dreams about?>> <<@ph11p3540 says : That last 2022 PSU standard and Intel 13ths generation CPU socket motherboard standard really was a surprise to me. My 20 year old 850w semi modular power supply lacks the main connectors for the secondary paired 8 pin power connectors to the mobo. Time to buy a new 1050 watt fully modular power supply. Overpowered power supplies are harmless while the incorrect connectors and power supplies running past 80% power needs are dangerous to a PC. 4 and 6 pin secondary mobo power connectors are dead>> <<@Bobcat665 says : Thank you for the history lesson! It was interesting to learn about when and what changes were made to the industry standard over time.>> <<@cafeplazay says : 😀>> <<@Alpha-ms9nj says : I recently had a no boot no beep issue with an old HP Z230. Thought it was the PSU. I learned that HP Z workstation PSU's are proprietary and are 11V standby and 18 pin motherboard connection. Thankfully after further diagnosis I changed the CMOS, got it to beep 5 times that pointed to the CPU which I cleaned and it booted. Always great videos on this channel that is a source of informative information, thank you.>> <<@kueifengtung says : I recently bought and built a desktop that uses a 4070 with 80plus gold power supply. The shop recommended me against getting the platinum because from his experience with clients, they break at a much higher rate. It is true that the more complex something is, the more parts there are to break. But in this case, Is there any truth to plats being less robust than gold?>> <<@Gato303co says : Nice illustrative video. I have been seeing the hatred for the Molex connectors, I used them in the past, and even being kinda problematic to handle and connect properly, I still don't see the problem with them>> <<@Mruczek123 says : there is a great lack of translation of the lecture into Polish>> <<@miteshvallabh says : Thanks for all the videos and all the useful content. Can we get something on KVMs? What to look out for, how to best use a KVM? Also can we get something about having a PC in 1 room but being able to access it in another room as well, similar ro Linus' home setup (from LTT), but maybe a bit of a cheaper solution using a HDMI extender or something similar? What about a solution for having 2PCs sharing a monitor, keyboard and mouse in room 1, so they could use a KVM, but them having one or both of those PCs accessible in other rooms on a totally different monitor, keyboard and mouse?>> <<@MitchellJBridges says : This video was quite helpful for me when I build PCs. I had very little knowledge on PSU's so I thank you for this great insight. Keep up the great work.>>
