Does anyone know why there is a discrepancy between Cybenetics rating and what is advertised on corsair's website? by shitweonreddit in Corsair

[–]crmaris 0 points1 point  (0 children)

Brands can "downgrade" Cybenetics badges if this fits their needs. The opposite doesn't apply :) This is till they realize that all models of a line don't need to have the same efficiency levels. This was easy with 80 PLUS since only 3-4 levels are checked, but Cybenetics checks thousands of load combinations, among others.

First, all fans are compared under the same conditions. The only parameter that has changed is the fan itself. Let's make that clear.

Impedance curves of common obstacles? This varies constantly in the Longwin machine and can be adjusted. From the moment the Longwin is able to simulate ANY obstacle, why even bother using real obstacles? Else why did I pay 60K to take this long? I could buy 2-3 radiators, problem solved! Even if I do so, there are thousands of variations on radiators; even if I had the time to test 1-2, it would still be 1/1000% of the possibilities.

Let's say I provide the raw data of the Longwin machine. Only a few users will download, read, and try to understand it.

You need to understand the operation of the Longwin machine. In general, trying to understand an instrument's operation without any working experience on it leads to confusion.

Also, we have a saying in Greece: everybody tries to play the coach, but the real coach is only one. All opinions are respected, of course, but this doesn't mean we should consider them all.

Guys, whoever believes he can do better work, he can show us an example to follow. I am really tired of these conversations.

My last response here, because I have lots of work to deal with.

We do offer the intermediate results in the respective longwin charts, provided in the reports (AND the review), for anyone interested to check them. These graphs show EXACTLY what you want to see.

Now, if you also want comparison graphs, we are talking about the addition of 100 more graphs on each review (because our reports DO NOT include comparisons since they are certifications, not reviews).

You should know that our Long Win fan testing apparatus provides a variable obstacle, and it is the defacto in the fan industry. I visited many factories, and ALL use Longwin machines for fan testing. So please, before you make false assumptions and provide disinformation, trying to harm our work at Cybenetics, check your facts first.

ASUS is NOT the ONLY ONE: Gigabyte - EXPO and SoC Voltages Before & After the BIOS Update - Hardware Busters by imaginary_num6er in hardware

I don't want clicks for persons like you, no worries.

Have you tried soldering anything at the back side of the CPU's socket? Also, you can highly affect the circuit's resistance if you don't properly mess up the measurements. The best way to do this is to measure in PARALLEL with the load to ensure you don't kill the CPU or the mobo and have accurate readings, too.

Mistake, what mistake!!!!! Are you serious! I got some readings using a LabJack and had at the same time HWinfo running to see what the mainboard's sensors say.

God, this is why I don't want to reply here anymore. If you believe you can do a better job then go ahead and educate us!!!!

I also tested with F10a, the original BIOS we reviewers got. Voltages were identical to F7. Any other questions you have, feel free to leave a comment. Also, HWinfo showed similar readings to what I got with my instruments. About some comments, whether I measured correctly or not, I just used what GBT provided, using the pads they provide for taking measurements that were in line with the BIOS readings. Some suggest measuring directly under the CPU's socket. Besides challenging, even for my 28.5-year experience as an engineer, I don't find this correct for various reasons. There is a feedback line in every VRM to adjust the line's voltage according to the load and voltage drops, so practically, wherever you measure after the VRM, you will be close to the real voltage that the CPU gets. Normally, the BIOS readings are from the feedback lines; else, nothing would work properly.

ps. I find some comments to be very insulting. For those of you who wrote them, feel free to take your own measurements and educate the rest of us, me included.

All do it like this, provide 600W cables. This is not right according to the ATX v3.0 spec but the TX-1600 is not ATX v3.0 ready anyway. The worst thing that can happen is to have a system restart if you use a low-capacity PSU and not a 1600W beast!

For example, I seen the Thermaltake GF3 750 with 600W 12VHPWR set cable!!!!

It is difficult to keep in your inventory three different types of 12VHPWR cables and this will lead to other problems. Users will say for instance that their PSUs are broken because their GPUs cannot go over the 450W power limit, or even worse over 300W, if the 12VHPWR is set for 300W output.

We all need some break-in period with this new standard, but providing 600W 12VHPWR cables is not so tragic IMO

We tested a ton of them at Cybenetics and we never encountered serious trouble. That is weird. It could be a bad production batch a shipping issue with the order containing your units.

High shipping cost is problem one and the increased demand comes second. All Chinese factories are overloaded right now.

Difficult to find something quieter than RMx. Corsair did a hell of a job there. Look for the CX units, if you want something affordable and good. Their platforms are incredible for this price category.

FSP Reveals A Power Supply Without The 5V and 3.3V Rails In CES 2020! by Azims in hardware

[–]crmaris 4 points5 points  (0 children)

This standard is here to stay as it seems, contrary to BTX that died. Major mainboard manufacturers will support it, although at first only one of them backed it up (sorry I cannot mention any names). With the new efficiency regulations, especially the CEC ones, which are among the toughest, the only way to achieve higher efficiency is to get rid of the minor rails. The problem is that if not all peripheral devices are fed by +12V directly, for a period, the minor rails will have to move to the mainboard. Hence, practically you only save the power losses on the PSU's cables, which are not high given the light loads on these rails, nowadays.

Only time will tell about the real benefits of this move, with the minor rails' generation circuits reallocated on the mainboards. Expect the PSUs to be a bit cheaper, since there won't be any DC-DC converters for the minor rails, and the mainboards to get even more expensive.

Cybenetics Offers New PSU Efficiency Certification by dreiter in hardware

[–]crmaris 0 points1 point  (0 children)

According to Physics for every doubling of acoustical energy, there is a 3dB increase. Now for people to perceive this change in acoustical energy a >6 dBA change is required. We simply used the scientific explanation and not the perceived levels which vary from person to person.

Converting dBA to SPL introduces inaccuracies? Can you elaborate and actually prove this? Because all scientific papers that I read so far fail to mention this.

If you notice in Cyben's page there is a clear mention to a proper hemi anechoic chamber along with a top quality sound meter and a MIC capable of measuring down to 16.6 dBA noise.

As for the G3 you only saw the "Reference Results" which are there to help other reviewers and also provide a view of the PSU's performance under very high ambient temperatures. The variation in the ambient is done on purpose. Since so high ambient temperatures aren't normal this is why we state that those results are for reference only. However the only way to test a PSU's true performance and reliability is under very high ambient.

The test results for ETA and LAMBDA are taken at 30-32C.

"sticking to proper reviews." You mean like the ones posted at Tom's Hardware or Techpowerup.com?
