Question

Hello! I want to update the system unit - the computer Dell Vostro V 3900 Mini-Tower.This computer has the following characteristics(or should I say limitations, by that I mean the motherboard):Processor:Number of cores 2 (max 2)Number of threads 4 (max 4)Manufacturer GenuineIntelName Intel Core i3 4150Codename HaswellSpecification Intel(R) Core(TM) i3-4150 CPU @ 3.50GHzPackage (platform ID) Socket 1150 LGA (0x1)CPUID 6.C.3Extended CPUID 6.3CCore Stepping C0Technology 22 nmTDP Limit 54.0 WattsBIOS-------------------------------------------------------------------------UEFI YesBIOS Vendor American Megatrends Inc. Chipset-------------------------------------------------------------------------Northbridge Intel Haswell rev. 06Southbridge Intel H81 rev. C2Bus Specification PCI-Express 2.0 (5.0 GT/s)Graphic Interface PCI-Express 2.0PCI-E Link Width x16 (max 16x)PCI-E Link Speed 5.0 GT/s (max 5.0 GT/s)Memory Type DDR3 DMI Baseboard (Motherboard)vendor Dell Inc.model 0T1D10revision A01 I want to install in this motherboard the most powerful processor which I can put here: will Intel Core i7-4790 fit in here? As I understood I should search for only those Core i7 processors which start with 4 in their name because initially there Core i3-4150 was installed from the factory.Then I want to put the most powerful graphic card which I can put here(even if it will be outside the case, I think it is possible to connect the card just using extension cables?)(Is it possible to put 1080Ti or analogue from AMD or something more powerful?)Then I think it is needed to change the power supply, the computer has a 300W power supply, 80Plus Bronze (does not know what it is though). Or will it be still enough?Then I want to add RAM, as Core i7 supports 32 GB of RAM, but there are only two RAM slots on this motherboard and I think that I should buy 2 modules each of them should be 16 GB. But I am confused by the fact that there are almost no mentions on the internet that people install 2 modules of DDR3 memory each of them by 16 GB.Then I want to add the fastest SSD with a volume of 2 Terabytes(can I put here M.2 SSD? somehow, using PCI-express adapter), the motherboard has two SATA 3 ports and two SATA 2 ports.Then I want to add an HDD of 2 Terabytes with a spin speed of 5200, as I think they are more reliable than those with the spin speed of 7200, to make back-ups of SSD.I think I listed all the parts to upgrade to make it the fastest computer based on this motherboard. I want you to advise me.Thank you in advance.

Re: the most powerful processor which I can put here: will Intel Core i7-4790 fit in here?

i7-4790 is top cpu. no need to get 4790k as bios does not allow overclock

I want to put the most powerful graphic card which I can

GTX 1070/1080/1080Ti or equivalent AMD cards.

Then I think it is needed to change the power supply,

600W or higher ATX psu. V3900 accommodates standard ATX psu with 24/4 pin

Then I want to add RAM, as Core i7 supports 32 GB of RAM, but there are only two RAM slots on this motherboard and I think that I should buy 2 modules each of them should be 16 GB.

should be no problem with 2x16 GB ram. Chipset is H81. On other H81 motherboard it is well known 32gb is supported, such as MSI.

Dell Vostro 3900 - MT -

Core i5 4460 3.2 GHz

4790 might need optional power supply.
