    Pedro Henrique reacted to NobleGamer in No Breaks(UPS) for a 850w PSU (Seasonic FOCUS GM)   
    Once you figure out the max power draw at the outlet (less efficient than what your parts actually use) for your system, you need to make sure the watt rating of the UPS is higher than that. VA indicates the battery capacity - See some online calculator for how long it might last.
     
    I don't think there is such a thing as a UPS being "incompatable" with a PSU. What you do have to look out for is:
    Watt rating of UPS is greater than your max power draw at the outlet VA battery capacity versus whatever your usage would be in a no-power situation The response time (or whatever it's called) for the UPS to give power when the power shuts off The amount of time a PSU can go without power before it shuts down (If this is shorter than the UPS's response time, then PSU just won't get power in time and will shut down

    my 'rule of thumb' is this:
    - run everything you want to run off the UPS at full tilt, note the wattage (use one of those power plug wattmeters if you must, they cost like 15 bucks..)
    - double that wattage (because ideally you dont go past 50% for battery lifetime reasons.)
    - find a decent UPS that as a WATTS rating (not the VA rating) that's close to or above that double wattage.
     
    about the watts / VA thing: UPS'es assume that what you wire up to them will have a horrid power factor, which means they can delver more volt-amps than they can deliver watts. and because VA is the bigger number, that's what is on the box. but down in the spec sheet they should state how many watts it can deliver. if it doesnt, ignore the product anyways.
     
    beyond that.. i generally avoid units that have a single 12V battery for running 'actual load' (they do great for stuff like network equipment), because they just get beat up too hard to get decent lifetime out of them. just a handful of power cuts will ruin the battery.
     
    as for an actual brand recommendation, all of my stuff is APC back-ups, and my only complaint is that replacing the batteries isnt quite as streamlined as one would prefer (the 1400VA units basicly need to be dismantled with some force..)
    they're all stepped approximation sine wave, which isnt ideal.. but other than making my power supplies a bit screamy it hasnt been an issue.

    Pedro Henrique reacted to RejZoR in The Edge of an Era -- Internet Explorer is OFFICIALLY DYING   
    Currently Windows systems literally have 3! versions of Microsoft's browser. Internet Explorer, Legacy Edge and new Edge. Ridiculous.
     
    Also I wonder if they'll finally migrate OS components and dependencies on IE components (like Explorer) and move them over to Chromium. I wonder if this will force NVIDIA to finally migrate their dumb, ugly and outdated NVIDIA Control Panel into something more modern and faster. Coz their stuff still runs on same IE from circa 2004-2006...

    Pedro Henrique reacted to Monkey Dust in The Edge of an Era -- Internet Explorer is OFFICIALLY DYING   
    It's the difference between catering to corporate and consumer markets. If Windows machines had to go in the bin after 4 years like phones because no more security updates, many business users would seek an alternative.
     
    As an example would you rely on an Android or iOS app to operate an expensive piece of machinery, or would you rather go with a Windows program safe in the knowledge it could still be made to work in 15 years?

    While this seems too good to be true, the concept of recycling waste from nuclear energy production into cheap, portable power is incredibly exciting. It could be extremely beneficial in medical technology, in low-power implants such as pacemakers and hearing aids. If it is scale-able, it could usher in a new dawn of consumer devices that never need to be charged. Imagine an Echo Dot that can be placed anywhere in your home without needing a single cable, or earbuds that never lose their charge. Applications in micro-mobility devices and electric vehicles are even more exciting, although this may be pushing the boundaries of rational optimism. At the very least, this tech is an avenue towards reducing nuclear waste.

    Pedro Henrique reacted to SolarNova in How to choose a monitor: What information to know, and where to find it.   
    “Give a man a fish and he eats for a day, teach a man to fish and he eats for a life time”
     
    The search for a monitor for many people ends in 2 ways:
     
    They purchase a monitor seen on a retailer site based purely on specs and advertisements, and are done.
    or
    They come to a technology forum and ask for advice.
     
    The latter usually results in them asking if monitor A or B is best, or what specs they should look for, and then people reply with suggestion usually based on the same advertised specs seen at retailers and/or 1st or 2nd hand subjective opinion.
     
    The problem with this is that the display industry has a hidden world of details that are very important for those who want to make an informed purchasing decision, but seldom few ever get to know these details, details that directly relate to the quality of the display and its true capabilities beyond the usual fluff marketing material. These hidden details are known to enthusiasts who know of the few competent, thorough reviewers out there that can provide those details. But being in the minority this results in advice from such individuals possibly being missed by those who need that advice.
     
    This is a guide on what information to look for, and where to find it, beyond the basic and often misleading ‘specs’ advertised by the manufacturers, retailers, and many of the self-proclaimed ‘reviewers’ seen online, so that you may make an informed purchasing decision on your own, for the most part.
     
    Let’s start off with an important notice:
    Any suggestions given to you for any monitor should be accompanied by a thorough tested review source, if it isn’t then such suggestions will be based purely on subjective opinion, often based on specs alone, which, as stated, can and usually are very misleading and missing lots of important information.
     
    Now let’s move onto the ‘guide’.
     
    Do not rely on advertised specs, and do not compare advertised specs. If its not a reviewed monitor, you're taking a gamble.
    As will become evident as you go through this guide and follow the links to reviewers, the advertised specs can be and usually are very misleading. You can use them to glean basic information like resolution, size, frequency, number of ports etc, but things like 'response time' should be taken with a massive grain of salt.
     
    Price:
     
    Display Size/Viewing Distance/Resolution
     
    Quality:
     
    Panel Types:
     
    Uniformity:
     
    Pixel response speed (Response time):
     
    Input lag:
     
    Colour gamut and coverage:
    This is a section I will not be getting into.
    The simple reason being that if it’s an important aspect to you, you should already know everything that needs to be known for your given hobby or profession.
     
    For the vast majority of people you won't need to know what things like the Adobe-RGB coverage or DCI-P3 coverage mean and are used for.
    It is however tested for by most competent reviewers and so you can look there if interested.
     
    Colour Accuracy:
    As with above this is most important for professionals and certain hobbyists, however this is still somewhat relevant for everyone in my opinion.
     
    HDR and SDR:
     
     
    Where to look:
     
    Now that we have gone through some of the most important 'hidden' aspects of Monitors, where do you find this information ?
     
    As mentioned, reviewers. However, you will need to find those who test objectively, display the results, and ideally also inform you of their testing methodology so you can compare displays across different reviewers.
     
    Here are a few places you can check.
     
    Why isn’t LTT included?
    I like LTT as much as the next person, however, when it comes to display reviews they lack details, and are for the most part halfway between a ‘overviewer’ and a proper ‘reviewer’.
    Some of their videos will include information like colour accuracy and gamuts, they may even attempt a basic ‘blur’ amount test, but they are not currently at the level of Rtings or Hardware Unboxed. If you see a monitor on a LTT video and you think it looks good, I would still suggest you check the above sources first before purchasing.
    Update: 17/12/22
    LTT labs is now capable of providing detailed reviews of displays, keep an eye out for future reviews.
     
    TVs as a monitor?
    This ‘guide’ isn’t for TVs however a quick word on them
     
     
    Why should you trust the above information to be true?
     
    Display manufacturers are tight lipped when it comes to specific information about their displays that are not included in their advertisement material. And for good reason, no one wants potential customers to know the faults of their products.
     
    However, statements like "the response time spec is massively misleading" can be tested, and has been. Every reviewer who tests pixel response speed comes out with an average pixel response speed that is different from the advertised specs, some even go so far as to try and replicate the advertised spec, and that is where we find out how the manufacturers get away with advertising these figures. They are 'technically' not a lie, just hugely misleading.
     
    This is the same for all the above information, reviewers that have shown their testing method can confirm all the tested information they have gathered and it can be replicated, within panel variance, and thus confirmed to be true.
     
    With the above information in hand, and links to a few reviewers where further more detailed information can be found, you should have all you need to make an informed purchasing decision when looking for a monitor.
     
     
     
    If anyone thinks I should add any information to this post, do feel free to speak up.
     
    Thanks to @Glenwing for help with format and error checking.

    Summary
    Thermaltake, the Taiwanese Case, PSU and cooling components manufacturer, releases two new Thermal Pastes, the TG-30 and TG-50, with a special twist: It includes a uniquely shaped stencil that is just as big as a LGA 11xx or AM4 IHS. The Stencil has a Honey comb pattern that allows you to evenly spread out the Thermal Paste onto the IHS. The packaging of each the TG-30 and TG-50 include the Thermal Paste itself, a spudger, the stencil with the Honey comb design that is made out of Acrylic and two Alcohol cleaning wipes. The TG-30 boasts a thermal conductivity of 4.5 W/m-k, while the TG-50 delivers up to 8 W/m-k. Thermaltake sells the TG-30 and TG-50 for $8.99 and $11.99 MSRP, respectively.

    This is bit a ridiculous, like they don't have to reinvent the Wheel here. Thermal Paste application is already easy enough, just place a decent sized dot in the middle and you're good to go. IMO. But I think this might be a bit helpful for those people who built a PC for the first time but then you gotta clean the stencil and spudger afterwards and you waste quite a bit of the Thermal Paste in the process. Well I guess to each their own but I will stick to the normal application method with Higher End Thermal Pastes like NT-H2 and Thermal Grizzly.

    Pedro Henrique reacted to GoodBytes in Windows 10: Don't know what's in a new update? You will now, says Microsoft   
    Well Microsoft already those release notes. They just release it several days after the update is released. All I see them doing, is no longer have to wait so long for this, and now make it some startup page with Edge after you update OR have a link in Windows Update  that says "What's new" or something, when a new version of Windows 10 is ready to install. That said, they never, not even if you are in the insider program shares all the bug fixes, known issues perform. Just some key points. I think that will remain. Then again, no one really cares about the inner details, and miss interpretation (by the editor(s) which aren't teh ones that worked on it, and while have technical background, aren't experts, and may miss understand a dev (who might have a communication problem due to English being a second language, laziness, or makes sense for him/her in their head but not to others)) can be an issue. 
     
    I am interested in better error messages than "Something Happened". But, probably, if I ask, they'll change it to:  "Something Happened - A certain event has occurred which may or may not be expected that potentially did something. Contact your administrator for more information."

    reduce some specs to get a better gpu, 1660 not that great for that budget. 2060 or RX5600 is better.
    3600 vanilla can overclock near the xt performance.
    You don't need 750w to run this, 550w is okay.
