PS3 Need Power Prong Measurements

Thanks, so i was wrong in assuming all the PS3 PSU's with plane plugs had the same size (im glad i added a question mark to that sentences, that question mark indicated that was speculative) and they was really reducing manufacturing costs in his design. Im not telling it as a bad practise in this case, is just it suprises me a bit they was taking so many care about this small detail, lol
Probably this changes represented a reduction of manufacturing costs of something ridicully small like 0.0000001$

Btw, for the values you added for superslim i think is better to change width=1.6 mm to 1.5mm and thick=0.6 mm to 0.5mm
This way we are rounding them with a precission of 0.5mm (more noob friendly and non conflictive)
In the way you are doing it you are using a precission of 0.1mm thats what i mentioned before that is a bit excessive :D
But feel free to do whatever you want, wiki is a collaborative project, i spend some time rebuilding that table but if you want to do some change i trust you
You have been meassuring the sizes for all/most PS3 models in the last days, so you know his sizes a lot better than me... and you have a better understanding than me about how to represent them in the table, etc... so is your decission ;)

Also the CECH-3000s are grouped with the super slim plugs but I'm unsure if they have the same plugs as the CECH-2500s. I don't think I did that and I assume they were grouped like that for space reasons as the prong text wouldn't fit.

I don't have a CECH-3000 motherboard to take measurements from.

If the 3000s plug grouping is wrong feel free to fix that if you know how.

Hmmm, i think the size of that plugs in the CECH-30xx should be together with the other slims, actually i remember there is somewhere in wiki (maybe in talk page) where is mentioned is posible to swap his PSU "with force" (im not sure what that means and how bad sounds that)
If someone reading this talk knows it, please tell

And right now i have lot of doubts why there is a "rowspan" grouping together the "power output" and "rating cummulative" for CECH-30xx and CECH-40xx
I need to review that pages of each PSU model to try to understand if there is some mistake in the table

I been checking this and the way how is grouped the info in the columns for "power output" and "rating cummulative" is fine, there was an small innacuracy in the APS-330 info thought, but i fixed it

To me this coincidence in between the values for "power" and "rating" indicates that the electronics probably are very similar in between the last PSU for slims, and the first PSU for superslims
At that point they was redesigning the PS3 case plastics so it was needed to modify the design of the PSU externally... but for the PSU internals it looks they was more conservative
This is just a curiosity though, we cant apply this theory for the plug size

The plug sizes of the last PSU models for CECH-30xx "should" be generationally more closer to the previous PS3 slim models... either identical or something intermediate in between the sizes i wrote for slim and the sizes you wrote for superslim

It was not you who grouped them that way btw, i been reviewing a bit the history of the page and is grouped like that since many time ago (click in the "prev" links at left of the list to see the details of every edit and a preview of old revisions of the page)
https://www.psdevwiki.com/ps3/history/Power_Supply

I guess the reason why the columns for the plug sizes are grouped like that is because i was confident about the plug sizes i was publishing for CECH-20xx, CECH-21xx and CECH-25xx... but i was not sure about the next ones, so the last group was a bit like the unknowns
 
The motherboards that I actually have are COK-001(CECHAxx), COK-002(CECHCxx), DIA-002(CECHKxx), JSD-001(CECH-25xx), JTP-001(CECH-25xx) and MPX-001/MSX-001(CECH-40xx).

Those are where I took the measurements from.

As you said more then likely cross compatible and/or similar PS3 models should have similar plug measurements.

This isn't related to the PSU but since you're working on an adapter I was wondering if you'd considered making some sort of clone of the fan speed adjusters that you see online that work without any sort of CFW/HFW?
As far as I can tell it's essentially just a little potentiometer circuit with a plug on both ends for the fan header/cable.

Check this project by @vyktormvmpay25 is the best open source DIY "fan accelerator" you are going to find
Is a clone of a device i bought years ago, and i can tell it works wonderfully, but dont get confused with other mods that works in a different way
https://www.psx-place.com/threads/ps4-ps3-hardware-fan-accelerator.31345/

Long story short... the PS3 fan have 3 wires, GND is connected to a shared GND of the motherboard (not to syscon), VOLTS is connected to a voltage regulator (not to syscon), and the third wire is connected directly to syscon and is a PWM signal
https://en.wikipedia.org/wiki/Pulse-width_modulation

The mods that uses a potentiometer are "cutting" the connection of the PWM wire... since that point the fan speed is "insensitive" to the PWM signal sent by syscon. And also it means the fan speed doesnt depends of the thermal sensors
Technically, thats mods with a potentiometer and a dial (that needs to be moved manually) gives a F%$# about the thermal sensors and syscon... they are bypassing them completly, and thats bad

The correct way to do it (like the one i have and the DIY from the link) is by taking the original PWM at the syscon output and modifying it (to create a different PWM signal on real time) then send it to the fan
For that to work is needed to use some chip that does some "logic" functions, in the mod from @vyktormvmpay25 is an atmega ttiny (and yeah is tiny)
Is needed to program the atmega 2 times, one for the bootloader+ports config, and other with the "software"

That software is what does the logic (with some easy functions of the kind... "if temp = x, fan speed Y, else Z etc...), is configurable... but pretty much what we are doing is to "boost" the PWM signal sent by syscon in +10 (or in a percentage, lets say +5%)
This way the resulting PWM signal is still dependant of the signal sent by syscon, and we are not losing any of the original syscon features
