    So....  What's the discussion here?

    Quartz11 reacted to leadeater in Performance of Rocket Lake locked CPUs can vary up to 50% on some B560 motherboards.   
    Ok so then you don't want to be able to change the PL2 value and the Tau values? That seems odd to not want something like that and be forced in to having less or in to spending more. A 10400/11400 is a great CPU for many at it's price for gaming and there is literally no good reason to want to bring back such restrictions just after Intel started relaxing them.
     
    If you don't want to buy their products then don't, that doesn't give a good reason to actively want to make products you don't already want worse, worse for those that may actually want them.

    It doesn't matter much for lower wattage power supplies.

    So did you double-check the liquid cooler tubes and where they connect to the CPU block?  Any signs of leakage?  Stuff on your top card seems suspicios.

    I'm talking about the default power limit setting it the BIOS: it's 65W "out of the box".  You can increase that power limit to a desired value in the BIOS to avoid throttling.
     
    "All modern Intel CPUs have Turbo Boost 2.0, which lets the CPU exceed its power limit for a few seconds while there is still power budget left—the goal is to average 65 W, not stay below 65 W at all times. "

    Quartz11 reacted to CerealExperimentsLain in What is the worst tech advice you've ever recieved?   
    This is just how AT computers worked before the ATX standard. 🙂  The power button before ATX directly caused the PSU to shut off.  Windows 9X even has this screen for AT systems, for when Windows has safely shut down and to instruct the user to press the power button to electrically turn off the PC.

    Quartz11 got a reaction from IIIIIIIIII in Corsair CX550 or be quiet! System Power U9 500W?   
    CX550 is a better rated PSU on the Tier list (B-tier as opposed to that Be Quiet! which is C-tier)
    CX550 works on 100-240V, so all you need is a generic (high gauge) PSU cable to plug into the CX550, in case it comes bundled with a wrong outlet plug for your country.

    Quartz11 reacted to Cheburek in Anywone here have heard doss psu 500w atx? Any personal experience in this particular brand?   
    A correction here:Most if not all tech products are made in China or more accurately in Asia.
    Nothing wrong with made in China in this case.
    What's wrong is that the power supply is absolute crap and the listing is suspicious as in full of lies about the product.

    Quartz11 got a reaction from RAZ0RLIGHT in Corsair RMx (2021)   
    Does anyone here own one of the 2021 units in their build?  Measured dB is a bit of an arbitrary number for practical purposes, because in an actual system lots of other factors will need to be considered for the audible noise profile.  Things like the case quality, material, dampening, PSU location within the case, other components, ambient temperature, temperature within the case, typical load levels, etc.  Also the frequency profile of the fan noise is super important: is it a quiet rush of air, is there low hum, are there any audible tonal components? It’s entirely possible your quiet case and CPU fans will be equal to the PSU’s, and you’ll never hear your PSU over them.  Presumably most people have case, CPU, and GPU fans turn up at load and becoming more noticeable too—not only the PSU fan ramps up. 
     
     All I see here is theoretical disappointment because the “numbers” are slightly higher, but it might be for naught in practice.

    Here's an interesting in-depth review of an RM650x 2021 (and a parallel review of an XPG Core Reactor 650W):
    https://www.computerbase.de/2021-05/650-watt-netzteile-test-corsair-rm650x-xpg-core-reactor-650w/4/
     
    That page discusses some sound testing that goes beyond most other reviews I've seen.  Very low fan RPM until loads 75%+.  The top graph can show more curves--click on the colored squares to add other PSU curves to the graph.
     
    "Thanks to the semi-passive operation of the Corsair RM650x, the fan remains switched off up to a load of around 290 W. The power supply works almost silently up to this load. For load 2, a deflection in the sound pressure level frequency spectrum can be measured just below 20 kilohertz, which the human hearing cannot or only very slightly can detect."
     
    "With load 3, an extremely low speed of 365 RPM can be measured for the RM650x. This means that the power supply unit remains significantly quieter than the RM650 , which lets its fan rotate at a minimum speed of 765 RPM and thus generates a sound pressure level that is almost 3 dB higher. The fan bearing does not work completely without background noises, however, as a quiet, grinding-like noise can be heard when listening directly. In the sound recording, however, it almost completely disappears in the noise of the microphone amplifier, since the sound power recorded by the microphone 50 cm away is negligible."

    I do not have a multi-meter unfortunately, and even then I'd be a little uncomfortable with my own ability to "check" it beyond a shadow of a doubt. Thank you for your input, I can't believe you frequent this forum and still help out where you can, that's wicked!

    ONE LAST TIME:
     
    1. The fan blade design of the Sunon fan is not as efficient as the Hong Hua fan blades.
    2. The triangles create a restriction that requires more air flow to push the heat out of the PSU.
     
    If you reduce the fan RPM, the components in the PSU will get too hot.
     
    Only the 850W is getting a corrected fan curve because there's enough thermal margin there.

    Quartz11 reacted to jonnyGURU in PSU life expectancy / performance degradation   
    That's Stefan.  But I've come to accept that a lot of it comes from the fact that he's German.
     
    Fact of the matter is, real life testing isn't available.  i.e.  Same unit tested 10 years ago is tested again today.
     
    There's MTBF, but that's done at maximum load/temperature/etc.
     
    There's DMTBF, but that's even done at maximum usage.
     
    Some things we do know: 
     
    1.  Fans fail first.
     
    2.  Capacitors fail second.
     
    3.  Most PSUs *should* last 5 years at 100% load, max temperature rating if used 24/7.
     
    4.  Based on experience, typical use of a PSU (typically 50% or less of PSU's capability) should last about 10 to 15 years before the fans die or caps start to leak.

    Quartz11 got a reaction from boghubodaghi in Looking for a recommendation for a reliable ~$50ish 400W or so PSU   
    Are you looking at the right model?  The low wattage 550W G3 does not have such an aggressively loud fan curve of the higher wattage models:
    https://www.cybenetics.com/index.php?option=database&params=1,0,36
    550W is rated as A- with average noise rating of "26.53" dB.  Looks like without the passive mode enabled, it should be up to 25 dB with my particular system's maximum load.

    I'm going to keep the fan on full time for my mother's system.

    Quartz11 got a reaction from Scania556 in How often should one replace PSUs?   
    That's just the advice I received, including from someone highly knowledgeable about PSUs.  I have seen the same advice in some other threads about older power supplies, how some parts age even while sitting unused, and age + usage will still have a detrimental  cumulative effect.

    Quartz11 got a reaction from Middcore in Some humorous, exasperatingly bad, or even off-the-wall crazy product reviews you've encountered   
    There are actually quite a few Amazon answers that are like: "I don't know", because people receive e-mails from Amazon prompting them to respond to another customer's question about a product they had bought, and these owners think they Must post some kind of a response.
     
    I miss the comment section for Amazon answers and reviews--it was a good place to add corrections.  Not anymore, you can only mark something as helpful or report it.

    I'm also not sure about all the 1-star "DoA" reviews that are common at all retailers.  On one hand you want to know the rate of DoA products, on the other hand... it's not really a product review.
     
    Also, some reviews say something along the lines of "I haven't used it/opened the packaging yet, but it looks nice."  Why are you submitting a review?!?!?
