  1. A 14-pin connector? That must be some sort of odd-ball proprietary connector. Older ATX form factor motherboards used 20-pin connectors, and now use 24 pins. I would assume that any 'standard' power supply would only have the usual 20/24-pin connector. The 14-pin ones would probably be propriatary and expensive. In any case, there should be no problem using an adapter PROVIDED that you are sure that the adapter is designed to work with your particular motherboard. Given that the 14-pin isn't 'standard', there could be several variations of pin layout.
  2. Get into the BIOS (with the 730 installed) and check the settings for the graphics. There should be a setting similar to "graphics enable" which may have settings to enable PCIe, on-board/IGP, and/or "auto".
  3. For gaming, an i7-7700K is better. (Or even an i7-7700 if you don't OC.) Keep in mind that for "slight video game coding and video editing" you don't really need all those cores. The only thing that changes is the render times, and saving a few minutes on render times occasionally, doesn't mean a whole lot. But then again, I'd stick with the 1700X just because.... (it aint Intel )

  5. I don't think he needs to worry about erasing his floppies.
  6. There is really no reason to be that concerned about the temps. If the card was running at 57-59C it wouldn't perform any differently. I suggest you go back to the original fan and reduce the noise.
  7. Efficiency curves differ because circuit design, components, etc, varies between different models/brands. Yes, less heat is generated at higher efficiency because less power is wasted internally. (duh) However, there is no reason to assume that a particular 1Kwatt PSU would be more efficient at a particular load. A 1Kwatt PSU that is 85% efficient at 400watts output would produce the same amount of heat as a 500watt PSU that is 85% efficient at 400watts output. Note - this is the total quantity of heat, not the temperature of any particular part.
  8. CPU workload: Keep in mind that the only time you will be using all thread is during the actual final rendering. While you are editing a video, you will only be using a few cores. The only difference that having more cores makes is in the time it takes to do the final render. Unless you are in a professional enviroment where the time is actually important, it's not economical to spend $1000 on a CPU just to save a few minutes render time. If the number of PCIe lanes is important to you, you could use any less expensive Threadripper with fewer cores and just spend a few extra minutes drinking your coffee while it renders. Future-proof: Epyc processors are more geared to towards handling databases in large websites, etc. and I can see no advantage to them over Threadripper for video editing, etc.
  9. Actually electricity (in electronic circuits) has everything to do with heat. It's the consumption of electricity that produces the heat. What did you think causes the heat in a resistor - magical pixies? (And, of course, it's not just resistors that have "resistance" and/or generate heat.) The 400watts that the power supply would be delivering (in this hypothetical case) is the power consumed by the components - CPU, motherboard, GPU, etc - and would not be the source of the heat produced within the power supply. The heat produced within the PSU is the result of the power consumed within the PSU itself in order to deliver that 400watts. In this hypothetical case, an 80+ power supply would be drawing 500 watts out of the wall in order to deliver 400watts output. It's that extra 100watts of power consumed that generates the heat within the PSU. Whether the 80+ power supply is capable of delivering 1Kwatt or only 500watts, at 400watts output there would be 100watts of wasted power. This wasted power is essentially turned into the same quantity of heat. The components in a 550 watt power supply could be just as capable of withstanding this heat as the components in a 1000watt supply. The level of noise produced by a power supply would be a function mostly of the cooling system. A 1Kwatt power supply generally has, as you said, larger heatsinks, etc, and so can often deliver lower levels of power without even turning on the fan, but, it is, of course also possible to build a lower wattage power supply with larger heaksinks so it's fan doesn't run as often either. There are even some passively cooled power supplies that have no fan at all. Generally speaking, it comes down to a price/performance issue. It's possible to build power supplies with all manor of cooling systems that develop more or less noise based upon the internal components and the quality, size, etc, of the fan (if any).
  10. Lol! I can't help laughing at this. 1. Just because a power supply is rated at 1Kw does not guarantee that the components in it are any better "quality" than those in a 500watt supply. Many of the components are exactly the same - it's mostly just the actual current carrying components that are more highly rated. 2. While it's true that the 1Kw PSU would only be using 40% of it's capacity, at 400watts it's producing roughly the same amount of heat as a 500watt supply. The only difference in thermals would be the difference in efficiency between the two supplies when running at 400watts. It's quite possible that a 1Kw supply could actually use more power at 400 watts output, than a 500watt. depending upon the overall efficiency and design of the particular supply. 3. Differences in the temperature of any particular components does not negate the fact that you would be essentially creating the same amount of actual "heat". The heat doesn't disappear because you measure a lower temp - it's simply more diffused*. 4. At 400watts output an 80+ rated power supply would draw roughly 500 watts from the wall. The only difference would be the "actual" efficiency of the particular power supply at the 400watt level, which would only vary by a few percentage points. As above, the 1Kwatt could be 85% efficient at that output while some 500watt supply could be 86% or whatever. 5. The life of the capacitors would be determined by the quality of the capacitors and the heat/temperature of the capacitors themselves. In a higher rated power supply the capacitors would generally be "larger" - that is, have more microfarads - but they could be the same voltage and "quality" as in a lower wattage power supply. It's the voltage (and the power supplies ability to not exceed it), quality of construction, and localized temperature that most affects longevity. * this also applies to CPUs and GPUs as well. When you lower the temperature of a CPU/GPU by increasing the cooling, you still have the same amount of heat being produced - it's just not localized at the chip as much. The same quantity of heat still goes into the surrounding atmosphere however - it doesn't magically disappear.
  11. This is not entirely true. If your system is consuming say, 400watts, your 1000watt PSU needs to work just as hard as 550watt one does, to produce that 400watts. You can also get passively cooled, lower wattage, power supplies that are quiet all the time. Unless you actually need 1000watts - which would basically mean a highly overclocked system with 3 or 4 way SLI/CFX - it is very un-economical price/performance-wise to get a 1000watt psu. And before you talk about "efficiency" - you'll need to run your computer for a long, long time to recoup the added expense of a larger (or gold rated) power supply's extra initial cost. In any case - in answer to the original poster - they make 800watt SFX PSUs because people will buy them. People buy them because they (mistakenly) think more watts is better. Given the current power draw of most ITX systems, very few people would ever need more than a 650watt power supply. (I for example, am using a 650watt ATX power supply in my ITX build because I'm running an older, power hungry R9 390. If I was using a GTX-10xx, I'd need less). (And yeah, I know, there's going to be someone who talks about their ITX system with an overclocked X99 system, etc, etc, or some special situation involving a custom build, but ... ) EDIT - My bad - I misread the original post as 800 watts instead of 600 watts. There are of course, many situations where you could use a 600watt SFX power supply. For example, building a system in a Node 202 case with an AMD Vega graphics card.
  12. I'd start by resetting the CMOS/BIOS/UEFI. Using the hardware CMOS jumper would be best. Next to that, use whatever key during boot-up to enter the BIOS/UEFI (check the manual) and "Load Defaults" Also, check that the motherboard is compatible with the M.2 drive, especially if it's NVMe.
  13. I'd go for 6th generation and keep the RAM. In regards to AMDs running hot - I never had any problems with AMDs not lasting, except for some instances where people tried to overclock them too much (particularly the old FX series) Overdriving and creating excessive heat can shorten the life of any CPU - Intel, AMD, or whoever.
  14. These problems are usually caused by a flaky power supply or motherboard - particularly bad "bulging" or leaking capacitors in either unit. Try borrowing a different power supply (for testing). Inspect the motherboard for signs of leaking or bulging capacitors. Of course, any part of the motherboard or PSU could be flaky, so direct replacement is the best troubleshooter.
  15. That just depends upon how delicate the bad connection is. It can be almost instantaneous, or it can take a while. An oxidized joint can be "self-heating". Can you borrow a GPU to test it out? The test GPU doesn't need to be a GTX-970, but preferably it should be some nVidia model that uses the same driver - GTX-750, 950, 960, etc.
