7050 MFF 65W TDP CPU?
Hi! Using 7050 Micro with i5-6500T. Decided to upgrade it to 7th gen. Targeted at i7-7700T as a maximum possible variant, previous experience with Lenovo, HP pointed that T versions of CPU is the maximum possible in MFF systems. But surprisingly found these lines in the manual withing these psu specs that are possible.
Based on them, MFF supports regular 65W CPU i7-7700, not 7700T. But i never ever saw any MFF configurations sold with these CPU's nor anybody ever discussed such upgrade possibility. Besides, cooling system is low profile and i don't know whether it can handle +30W heat dispassion.
So, my question is - does it really possible to upgrade MFF to 65W TDP CPU's like i7-7700, i7-6700 etc.? Are there any real users who have such 7050 MFF 65W TDP CPU's with 130W PSU and this setup is running ok?

Investigation is finished. I've found the 9CTFR FAN pics. All 7050 MFF configurations that was sold with 65W CPU's, like models with service tag: GV6WDH2, DJBNRK2 etc. was equipped with this type of CPU fan.
It have copper insert, thermal conductive pads for power transistors and is rated for 12V working voltage, 14 CFM while typical 35W system fan is 5V model with 10.5 CFM, one-piece aluminium construction and the mounting screws scheme is different - 4 versus 3.
That means 65W mainboard have a completely different layout. So, the answer of @JOcean about "according to manual..." is WRONG because can lead you to rash buying uncompatible CPU model.
The really correct answer is - if you initially had 65W CPU (or) copper heatsink with 3 screws on your mainboard, you are capable of switching between all models from list above. If your 7050 MFF was equipped with 35W aluminium 4 screws fan model 5JV3N, T-versions of CPU's from that list are the only possible upgrade variant for you because your motherboard is not capable of providing 65W power output.

Yeah, awesome reply with same page of manual that i've posted as a question. My question needs more than just quoting the manual. Confirmed needed change PSU, heatsink. None of these steps you can find in that manual.

From the 7050 manual these CPUs are compatible.

Yeah, awesome reply with same page of manual that i've posted as a question. Answer needs more than just quoting the manual. Confirmed needed to be changed for such upgrade are: PSU, heatsink. None of these steps you're able to find in that manual.
I've tried to dive deeper in this, found two service tags for 7050 MFF that was supplied as 65W systems: DJBNRK2 and GV6WDH2.
What is interesting there comparison to 35W configurations:
M3YMW CHASSIS, PWA INTEGRATED, MICRO, HF, 7050, 65W and 9CTFR which is the 65W fan module.
While 35W systems are assembled with:
433K8 CHASSIS, PWA INTEGRATED, MICRO, HF, 7050, 35W and 5JV3N 35W blower.
Unable to find any pics of the 9CTFR while 5JV3N FAN's are everywhere... It is not a big problem to change it like a PSU if their mountings are identical...
But the main question is whether mainboards are the same? I know DELL love naming absolutely identical parts with different P/N. I've also deeply inspected my mainboard to see if there any CPU supply phases FET's or capacitors, inductors are not soldered in their desired places (that's the most common way to reduce board wattage), but all components are there and no space left to install anything more.
So, if anybody can post a photo of their 65W MFF mainboard or can confirm success 35W to 65W upgrade, it'll solve my question completely.

I stand corrected. Thanks for the further information.

This is actually a pretty simple problem with many ways to tell.
65-watt board
35-watt board
The easiest if you have the original power supply that came with it is whether it's a 65W power supply or a 130W power supply.
The 65w CPU boards can't be supported with a 65w power supply as the CPU is not the only part of the system that draws power. So they come with a bigger brick.
So:
65w brick = 35w CPU
130w brick = 65w CPU
If you want to be the most accurate, you can understand and solve simply by looking at the model of your motherboard usually shown beneath the RAM slots.
Most Dell MFF motherboards have a model number other than the Dell part number usually printed in fairly large letters. I'll upload a couple of examples.
In the case of the 7050, the two motherboards I have seen often with them are:
D8-MFF-SF (this is the 35w board)
D8-MFF-SF65 (this is the 65w board)
If you look and you see that the part number has 65 or 65w at the end, then it's going to be a 65-watt board. If it instead ends in letters like SF, SW, etc, it's going to be a 35-watt board. So they actually try to make this pretty obvious and I've never seen a 35w board with the number 65 anywhere in it.
As denoted by someone else, yes, the CPU heat sink can be used as an identifier but I've found this to be a far more factual way of properly identifying your motherboard's CPU compatibility list as there's no way to do a google search for "7050 with 3 screws cooler CPU list".Technically in this regard though, even the chassis has a different part number between the two.
For the most part besides few markers, the motherboards are the same. There are some extra resisters and such around the 65w CPU socket which is why it has one less screw on the cooler. Please note that in future revisions, that's not necessarily a guarantee, however, the motherboard model number has always been done this way.
Note: You can not cross mix the CPU and board. 35w CPUs with the "T" at the end should be used in 35w boards. 65w CPUs without the T should be used in 65w boards.

My 7050MFF with 4 screws aluminum heatsink and 5V fan doesn't agree at all.
I'm working 5 hours / day and consumption is ridiculous vs the z590 i5-11600k with RTX 2080. Im using it for video edition and for AI. Just the GPU need more watts.
The 90Watts PSU is to blame, That's all. I didn't modify any component or BIOS, I just renewed thermal paste.
