  1. A high efficient PSU can be bad. But in general high-efficiency requires better components and produces less heat. So there is some correlation between efficiency and quality/longevity. Just not a causation. If the price difference between gold and platinum or titanium is worth it depends on how many hours you run it.
  2. Test if it works and keep it if it does. the state it is in they can't (or shouldn't) sell it as a new CPU anymore (bent and straightened pins, multiple strangers potentially touched pins while not grounded etc.) and woud have to dispose of it. And remember, they tried to cheat you first and tried to withhold the refund and lied to you and gave you the runaround. Sounds like you are a professional. So each of your hour cost $100+. If I follow above timeline, you more than paid for that CPU with your time.
  3. I got the Lenovo. For about 4 seconds the external monitor works and the chrome book display settings show the 2 displays. After that, no external monitor signal and the display settings don't show the external monitor. I tried 2 different USB-C cables with the same result. I put the Dell docking station back and it has a stable external monitor signal along with the 2 displays (internal and external) shown in the display settings. So there must be some compatibility issue with the docking station, or it is faulty. I have the feeling something else is wrong.
  4. Laptops don't have good cooling due to space limitations. You probably hear the fan(s) spinning up. they are OK for short bursts of power, but for endured gaming, they get hot. I'm sure some manufacturers are better than others, but this an inherent problem. Check if it is dusty and clean. And check if the fan works. Make sure air flow is not blocked. Other than that, this is how it is designed. The CPU/GPU will throttle based on temperature. While that costs performance, it will protect the hardware. IIRC there was a case where a manufacturer was sued for
  5. Thanks, mod. should have posted there to begin with. I ordered the Lenovo. I researched on the USB-C extension and it looked like the added length and connection reduces power. Probably why the small cheap devices only have the short cable, which I think is totally impractical. And since i already had 2 of the "cheaper" docks with he short cord requiring extension, there is a chance this is at least part of the problem. Thanks to all who chimed in.
  6. Thanks. another thing i didn't mention is i use a USB extension cable from the docking station to the Chromebook. the hub just comes with a few inches and that is not practical to have the cable clutter right next to the docking station . I actually mounted the dock behind the monitor. Could an extension like that cause the problems? the Lenovo just has a male-male cable, so it is designed for a longer cable. but it is possible tit tiny docks are not designed for longer cables. My extension is only 3-4 ft.
  7. it is a XE950QCA galaxy chromebook. On the back it says 65W input. When one connects a lower power supply, it will tell so and charge slower or not when in use. 48W probably fine, just want to avoid the CB trying to pull 65W, and the docking station heating up since it is rated to deliver 48W. Maybe I'm better off with the Lenovo. I already envision my daughter coming to me all the time because of the " insufficient power supply warning", even if it isn't serious
  8. Thanks. the anker says it has 48W power delivery (requires 60W). Would that be a problem when the chromebook tries to draw 90W (or whatever maximum rating it has)? My powersupply can provide 100W and that may damage the docking station. Or am i over-thinking this?
  9. this only seems to have one USB port? and i didn't really see if it also powers the device? the docking station I have from work is similar to this. So a really commercial type. I was hoping for something simpler and cheaper, but still usable and reliable.
  10. I'm sorry, I should have called it "docking station" or some thing similar. this is the last one i bought (and will return) what is it supposed to do: - connect to Chromebook via USB-C - charge the CB - at least two USB ports for keyboard and mouse - one HDMI 4K port - network cable port - some sort of power supply (100W?). but i already have a 100W USB-C power supply if the docking station doesn't have one there are hundreds of device... problem is, the cheap ones don't seem too reliable. nut sure if that is a problem of them b
  11. I already had 2 of the cheaper Aukey hubs to connect my daughter's Chromebook to an external monitor, mouse, keyboard and CAT. Both of them had some issues (sometimes flickering, sometimes no network). I'm just done with cheap crap and she needs it for school. From work I have one of the fancy Dell hubs (that also has Displayport) I lent her when she had a meltdown due to no hub function. This works perfectly. Bulky, and expensive, but works. But that is obviously not mine. So do I need to buy such expensive Dell et al device, or is there a medium option that is small
  12. As much CAT6 as possible. Any potential PC or TV location should get 2-3 ports. figure out where the internet comes in and have a closets there for the switches, modem etc. Plan where you locate MESH wireless routers. Plan out if you want any cameras or other devices with decent data througput. Determine what you mean by " smart" and what the objective is. Some people think they need a refrigerator that orders food for them, others need sophisticated HVAC control. Don't install things just because they are " smart". Be smart and decide how they are supposed to m
  13. Not so long ago there was no tracking, or only for a fee. So ETA is the 19th.... why not wait till the19th and complain then if it hasn't arrived? As long as it arrives close to the promised date, who cares? Sometimes I think there are no problems in the World and we need to find new things to complain about. when you order a car, it takes 3 months. and guess, what, no one sends you updates on the status unless thee is a delay. People still survive.
  14. This maybe a surprise, but computers can get used for other things than gaming and mining. I spend 10 hours every days with two 42" 4K monitors and iGPU. I'm actually sad AMD neglects iGPU.
  15. Many delivery companies occasionally get sloppy with updates. So it shipped yesterday and you already complain? Who cares who the company is, once it arrives it arrives. Does it matter if the person handing you the package is USPS, UPD or Fedex? Depending on where you live, the last mile can get done by a different company.
  16. OK, so basically a direct economizer where they accept the coolant to be 50C. I guess that is similar to doing the same with water cooling and letting ambient air cool the water directly. Except with water cooling you are very limited to what you cool (not transistors, capacitors) whereas this fluid cools everything. Heatcapacity of this coolant (really, a refrigerant) is higher than water. So if this refrigerant has direct contact with a CPU/GPU heatspreader and is at 50C, is that still enough heat transfer to cool a high-power CPU/GPU? Or do they add some heatsink to increase tr
  17. if you have powerful GPU/CPU, you likely lose performance due to throttling in a cheap case. so then you can buy a lower grade CPU/GPU if you have a cheaper case. Save even more money. I think if someone talks about RGB strips, but saves money on case or PSU... this is a matter of priorities, not budget. IMHO get good case + PSU now, add RGB later (if that really is important). Obviously this is just my 2ct. I'm someone who buys once and uses for many years and only upgrade what really became obsolete. Never had a failure. but most my PC use is working these days. so
  18. I had to look up PUE. It states top performers get a around 1.2. I assume that includes the need for a heat pump cycle and not just " free" cooling (economizer) assuming the climate requires heat pump cooling. How does one get the 1.03 mentioned in this thread? this can only be possible if you are in a cold climate and only need to operate pumps and fans. A good chiller has a COP of maybe 7. So you need about 0.14 for the chiller alone plus auxiliary fans and pumps. COP will vary with the lift required, which will depend on ambient temperature. I assume PUE is an an
  19. Disagreed. The case is responsible for cooling performance, which impacts longevity. Lack of cooling also causes thermal throttling, which will negate the top $ you spend on high power GPU/CPU. And buying a $20 cheaper case now, and then buying a better case later doesn't' really save money. And the case also is the thing you see every time you use the PC. and when building the PC you will curse your decision to cheap out. Same with dust maintenance. Case/PSU you keep for long. Everything else ages due to new development. Don't go to Starbucks for a week and tha
  20. You have to find out how your customer can use parts warranty. AFAIK the typical warranty is for end users, and then most only for the first owner. So that would be you as the first private owner of the part. Once you sell it, the part is second hand. So if there is a warranty case, you have to pretend to the company you bought from, it is your personal PC. And you also lose the warranty time from you buying, to you selling the PC. If you promise 1-year warranty, and the part fails just a day before a year, this will be more than one year from the day you bought it. and if the man
  21. Until OP pointed this out, I didn't even know there are different types. I only knew there is an English QWERTY and the German QWERTZ layout. I assume each country/language has some specific layouts. But what I don't understand is, why complain about it? In times of internet I'm sure in most the World you can order any type of keyboard you want and in Windows you can set which type you use (for example, setting language to US international allows umlauts and Euro symbol etc.). I bet there is software to enable any type of widely used symbol. No one is forcing anyone to
  22. Good points. Thanks for the insight. I guess they could have used physically different plugs if they pin them differently. But I assume the shape (size, number of pins) was already standardized somewhat or they used what was already available. Practically the best action is to only use the cables that came with the PSU. Unless you really know if the old ones are correct. What happened to the OP could really happened to most people.
  23. i don't think that comparison is valid. A CPU has many actually new features and actual communication. Even new CPU not always work in the same socket. It would hold development back if AMD was forced to make their CPU work with an intel board and vice versa. It isn't just that AMD uses the same pins than Intel and only swap pin locations. A power cable is just standardized (and that is standardized) 3, 5 and 12V of certain current. There is zero technical reason to not have that the same for all manufacturers. It also makes the aftermarket for cables more complex and expensive. S
  24. I'm curious where you will get information that established players don't have? Do you have an example like for this week what was important information, but wasn't covered already? I don't know all the tech news, but it looks like what is actually important, is already covered. For many of the tech news I don't even think YT is the right channel, a written news seems much more useful often.
  25. My only YT experience is being subscribed to 50+ channels of a very wide variety.... Ask yourself: - what makes you better or different enough than established players? - How do you provide better or " newer" news than established players? General YT thoughts: - big competition for the time. YT mostly gets watched while not doing much else (like watching TV). So there is limited time in a day unless you want to target the unemployed. A podcast, for example, can be listened to while riding, driving, working, doing housework... so a podcast has many more
