    heres a cheaper powersupply 80+ bronze and its evga so good warranty. this saves you 3 bucks
    65$ 9 or 10 dollars cheaper than current going by the trend it may dip to 60$ aswell

    I was referring to the 9100f, not the 9400f. Also, the vid you linked looks sketchy as hell, no voice commentary or anything, just some unprofessional looking graphs and there's barely any views at all.

    @brob in your link it states that turbo boost technology 2.0 only has 2 states pl1 and pl2, but in the article you quoted " Intel has had this in place for a number of generations of processors, and most of it didn’t actually matter, as the power draw for the full chip was often well below the PL1 value even at full load. "The E5-1620 has base of 3.6 GHz with turbo 1/1/2/2 basically in non stressful aplications eg only 2 cores loaded the xeon is always at 3.8 GHz when the xeon is loaded to 3 or 4 cores it only has a 100MHz boost so its 3.7GHz. Now lets take for instance the i7-2600k as 1620 is really only a slighty higher cache (2MB) version with same max turbo. using this article we can see that the load on cinebench R11.5 measured through the ATX12V connector is 86W . Now lets look at how the 1620 performs with that same benchmark.

    HMMMMMMM oddly accurate only few watts less power than whenaida64 is stressing which is mostly due to not being as fully stressful or maybe the cache is being stressed harder or perhaps its not reading the wattage past a certain point, who know i need to buy a current clamp to test my self. @Jurrunio can also test this if he remove all overclocking and sees what he should get as he has a 2600k. Its clear that overclocking messes with the power draw reading for CPUID as its not using normal states anymore.
    Have you ever held your finger directly to a VRM? You can tell the difference between a decent number of temperatures its a built in functions humans have if you didn't know. If There was a VRM temperature measuring device embedded on the board most likely if it was over heating it would throttle the clocks, if there isn't then it could have the potential to get ridiculously hot and thus detectable by my finger. So either way its going to be detected by one or the other. Also if you want me too i will buy a thermal probe give me some good recommendations so i can test it more scientifically.
     
    And if your wondering why i posted 3 posts in a row its the simple fact that when i edit a post you people don't even seem to read the edit like how @brob  responded because when i edit a minute after and then 2 minutes after they respond having the old edit not seeing the correction. @valdyrgramr  and @Norwegiantweaker i hope this clear this up for you.
     
    The reason for all this is the fact that an extra heat sink vrm is not worth the money for a 2200g that is only doing office work. The reason that the B450 is being used is to squeeze little bit more performance out of the RAM as A320 is locked to 2666. Here a article about the power usage of the 2200g the write states that this is the power usage of the entire system.  Here is Toms hardware that has power for as well but it doesn't include the entire system  around 54W avg to 65.5W max. Seeing as the the original poster stated that the work that is going to be done is CPU heavy, no IGPU tasks. The ryzen 2200g voltage at load is 1.36v which would mean 48.16 Amps draw through the Vcore VRM. 4 phases 12.04‬ Amps per phase. Looking at a B450 3+3 phase from buildzoid we can see that a beefy 3 phase vrm at 75A outputs 10.3W. taking this over estimate (since the vrm become more inefficient the more current you push through it) of the power used at 75 and scaling it down to 48 Amps we get 6.6 Watts total heat on vrm. Now spread over 4 phases its 1.65W per phase which in honesty doesn't require a heatsink with some small amount of air flow(coming from cpu cooler).

    now let me show you something very interesting. My xeon will only go to 87 Watts even though its a 130w part. But how could this be? Simple the e5-1660 the 6 core variant is actually 130w and the 4 core variant is a cut-down with 2 cores disabled. (130/6)*4 = 86.666 Watts

    so in this case the TDP does lie, but its not for the reason that you might belive as the TDP is very accurate for these types of cpus. There was a time not to far ago that TDP was actually relevant.

    As a form of energy, heat has the unit joule (J) in the International System of Units (SI). However, in many applied fields in engineering the British thermal unit (BTU) and the calorie are often used. The standard unit for the rate of heat transferred is the watt (W), defined as one joule per second. This tells you a good estimate of how much power aka watts aka Heat per second you will consume.  TDP is a good estimate of power consumption denoted in watts at least for older xeons as they stick to a very strick power profile as they dont turbo incredibly high or vary alot.

    he asked for 100gb and wants price down dramless is fine it may not have as stellar read and writes or last 20 year but it will easily last 10 years. B450M Pro4-F only has 2 more ram slots and he only needs 2 and same vrm 4 + 2 same features just 5 dollars extra. As for the power supply there perfectly fine ive never had one one them fail on me yet and Ive had 3 for a year now. His system will barrly pull 120 watts.

I picked the 2700 just to show you the price of the cpu i would recommend the 3600 or 3600x, The power supply 750W which might be over kill but its there as a place holder for any better psu deals but anything more than 88$ is not looking at. The Video card can depend if you want 2080 or 2070 or the new navi cards it just depends. SInce im assuming your going to have alot of files and clips i picked the best bang for the buck reletive to size and 7200RPM. THe SSD would be boot drive and any files that you want quick access too.

    I would not go for 8700k purely because ryzen 3000 is coming out and most likely it will go head to head with it which means free cooler and cheaper price (potential more cores)

    Asus is top notch but if you really want to look that hard into check out buildzoids channel, he reviews motherboards, there vrms and overclocking potential of boards, ect. Hes been going over some of the x570 boards that have images released to the public and when the new zen 2 boards come out hes going to go over pretty much all of them.

    I don't exactly know what your routers page looks like but this guide might help https://www.tp-link.com/us/support/faq/1217/
    You only need to do step 3 aka for 5 GHz
    Change the channel to be around 36 e.g. 32 33 34 35 ect.
     
    if its not the same as the guide send a screenshot of the webpage you have.

    As long as it doesn't use the 5vsb (5vsb is always on as long as the power supply is plunged in and the switch in the back is on this is what allows some parts of motherboard to glow and the ability to turn on the PC)  which spoilers it doesnt your fine.

    Lefteh got a reaction from CGameDev in Experimental Peltire Cooler   
    I believe the Peltier device will cause a bottleneck if the cold side is heated too much. The reasoning for this is that the hot side is insulated from the cold side. In theory, if you give it enough juice it will be able to keep up with the demand but its unlikely to help if you're going for overclocking. A great example of this would be when Linus tested having pc in a refrigerator. At lower wattages, it performed cooler, but at higher temps, it was overwhelmed by the heat being dissipated. Another disadvantage to Peltier is they get cooler than the relative air around them which will lead to condensation and from watching any NO2 cooling pcs moisture is the biggest enemy. Also, extra heat to dissipate when using a Peltier.  If I'm proven wrong that would be SICK because we could then go cooler than we currently can with water and air cooling. Although if you were to use water cooling you might be able to get it cooler than room temp IF you do hook a Peltier separated from the CPU and connected to the loop see the image.
     
    Another thing to consider is the specific heat of water so we can find the effective heat delta and the flow rate of the pump.
    Waters specific heat is 4185.5 J/(kg⋅K) at 15 °C  and waters specific heat is pretty consistent as long as it is water.
