    Not a huge fan of the book given how much medical advise says to keep young kids of screens as much as possible. Esp given the addiction psychology deployed by so many games to 'hook you' etc. the evidence of changes in brain growth wiring are very scary indeed.

You keep my spirits up when I'm low and I'd really love to meet you 💓like today is my birthday and I worked and spent most of it alone.... your videos made me feel better and is going to do like every night and help me sleep. Thank you

  • Geniwab

    10uf axial capacitors with the size of a brick??? ROFL 🤣🤣🤣🤣 They must have taken those from old CRT's, that card is more dangerous than anything else on the computer, those old caps usually short and make very nice fireworks xD

  • Garrett

    It would be interesting to have some type of expert on electronics like an electrical engineer or physicist or some other qualified person to dissect the board design of that card and explain in detail from an electronics standpoint what that board even tried to accomplish does ( or otherwise attempts to do ). I am not an expert, but am a bit of a hobbies, and to to me it just looks like a bunch of large capacitors, a huge resistor and maybe a few other smaller components like small transistors or simple integrated circuitry. I'm also not sure how much sense it even makes to try to scrub the power from your pc after it has already made it's way though the motherboard to reach the PCIe lanes. If you want to run clean power to your valuable devices, then the first thing would be to invest in a device that connects to mains and has outputs where you plug your devices into that maintain a clean 60Hz 120V/AC (If you're from North America of course). They essentially take the "dirty" energy from your wall, and monitors the voltage in order to keep the mains voltage from the outlet of your choosing constant with the help of a small-large rechargeable batteries coupled with an inverter and some circuitry (these can be bought without the need to purchase an expensive uninterruptible power supply, although I highly recommend going this route), then next invest in a trusted and reliable AC to DC power supply. You're looking at spending maybe $300 maximum depending on your setup and how many devices you have if you just get the UPS. And that $300 dollars is a small price to pay in order to protect potentially many thousands of dollars of expensive equipment. It's almost like an insurance plan, but you really only have to make one payment. Only cost is associated with it is upkeep the battery inside (Mine needs replacements about every 5 years and cost me about $80).

  • darkSorceror

    Would be interesting to see if this thing does anything to help with a PCI-Express soundcard. I had an Audigy 2zs as well (yeah, I know it's PCI and on a shared bus) and at first it sounded amazing, but with more and more graphics upgrades, it eventually became unusable. Also, a useful test not included here: FRONT PANEL AUDIO. The cable running from the motherboard-typically from the very back-to the case's front audio jacks acts like an antenna, picking up EM interference. And not mentioned here, but another solution to the same theoretical problem: audio over HDMI. The DAC is no longer effected by the graphics card, only by the monitor. Coil whine still causes problems for some badly constructed monitors, of course.

    If anybody reads this, I am having a lot of issues with power creating a lot of extraneous noise when I plug in my guitar pedals directly to mains power so if anyone could recommend a specific model of power filter, I would appreciate it. It has made recording while plugged into mains power impossible because the mains power creates so much unnecessary background noise

    Check for audio recording using microphone level input - this is when filtering matter because incoming signal is very low and its going to be affected after going thru hi gain amplifier stage and each noise get gain. Not saying card is working just couple cents from guy helping out in audio studio.

    I like how you can tell the answer by the thumbnail.

  • ThatGuyMigz

    This video pisses me off a little bit. I'm not saying that the card is not absolute junk. But the ways LTT is testing this is absolute bogus. Linus even MENTIONS that his motherboard has onboard filtering built into it. How the hell are you supposed to test that card that is meant for shit hardware, when you use hardware that isn't shit? Mentioning that it'd be better to "just buy a new motherboard" without keeping in mind that if you buy a new motherboard, you may not have the same CPU sockets available for example. If a shitty card could fix everything for just $40, I'd say it's somewhat worth it. I still think the card is crap, but when you say that you can't hear a difference because you couldn't hear crackling or something without the card. Then that simply means your setup is not shit enough. IMO, this video did little to nothing. It just recorded some video footage of how the card looks, but never actually tested what the card was supposed to do properly.

  • John Smith

    sound quality can be very different from board the board. and lot has to do with the DAC. my old am board sounds better than my newer intel. they are both considered older now but from my experience I think external audio would be better since you could down grade audio when upgrading a movie

    Generally, the problem is when you record stuff. In particular if you have something on a line in channel. So, in theory, if you have a device that can suck up that interference it would improve the recording quality.

    GRADO : Please fix the design for your cords! I've had 3 pairs of SR-80e over the years and they ALL failed because the cords tend to twist and eventually break the fragile wires inside. Linus's pair (much more expensive model btw) is doing the same thing.

    I love how unscientific their testing was they could get some actual result with an oscilloscope and could have figured out if it does anything at all. Also I love how it said it would help coil whine when that's a mechanical problem with the physical coils themselves not a power delivery problem :D

  • TAD2020

    The main reason for a dedicated sound card back in the Win 9x era was that onboard audio back then was done in software and thus on the CPU. So a dedicated sound card would give a pretty substantial improvement by offloading that from the CPU. Onboard now can still be software based, but doesn't really matter as the load on anything newer than like a P3 is relatively tiny by comparison.

    You have to use POWERED speakers. Not passive heahphones. Of course it makes no difference with headphones. I got this problem with my setup, because I use studio monitors and a laptop and I can HEAR the SSD working, when I don't listen to anything and copy files.

    Buying a power conditioner wont get rid of ground loops. And it also won't make one bit of difference to the power quality. Unless you spend a ton of money. The atx spec has tolerances for maximum allowable ripple on a power supplies dc output.

    TL;DR: Of course it's a scam. (And to a lesser degree, so are the fancy audiophool headest & amp stack Linus shows at 3:00, in that they aren't worth even a 10th of their ridiculous prices.)

    If you're going to do audio testing like this, why not go get some lossless audio off of Soundcloud / Bandcamp or something? Something that's free to share so people can hear what you're hearing? (not to mention you could be highlighting some indie artists)
