Max Optiplex 3020 MT build with a standard PSU

So, I recently acquired 3 Optiplex 3020 MT that came out of duty at the office. Now I've devised a brilliant plan to turn these computers into a maximum achievable one with the standard PSU. Why the standard PSU?, because I want to add a low profile GPU to the x16 PCIe slot. Why a low profile GPU? because (after my research) this is the cheapest solution for a good GPU without purchasing a new PSU and a comparable GPU.

The goal of the build is gaming with a reasonable FPS with 3 monitors.

The specs of the Optiplex 3020 MT: 
OS: Windows 10 pro 64-bit
CPU: Intel i3 4130
GPUIntel HD Graphics 4600
RAM
4GB DDR3 1600 MHz
HDD: WD 500GB 7200rpm
PSU: 290w

The Optiplex 3020 MT goal:
OS: Windows 10 pro 64-bit
CPU: NEW  Intel i5 4690 or 4690K
GPU: NEW  ZOTAC GTX 1650 Low Profile (x16 PCIe = 75w)
RAM: 2x 4
GB DDR3 1600 MHz
HDD 1: WD 500GB 7200rpm
HDD 2: WD 500GB 7200rpm
HDD 3: WD 500GB 7200rpm
PSU: 290w

So, the first question, will the standard PSU of 290w handle this max out build of the Optiplex 3020 MT?

The second question, if the standard PSU will handle it, should there be chosen for the Intel i5 4690 (TDP=84w) or the Intel i5 4690K (TDP=88w)?. The Intel i5 4790K will use more power and exceed the maximum TDP of the motherboard (TDP=84w) by 4w.

The last question, I do not know how much power 3 HDD use, but can I upgrade to 3 SSD that results in a lower power consumption?

 

Thanks in advance...

Re: Max Optiplex 3020 MT build with a standard PSU

IDK about all that, however ...

You should always over-size the Power-Supply. Then hopefully, while you are running the system at Max all hot-and-heavy ... the PS can still just be running at 50-60% utilization (cooler, more stable voltages).

That Power-Supply was tiny to begin with, and now it is old/worn .I would not push it any harder than you have to.

At least if it explodes, you have plenty of spare parts. 😀

I have enough spare parts with 3 given desktops 😜

Soo, your advise is to also upgrade the PSU.
What do you advise for the minimum power supply?

I'm not advising anything, as this project has no merit (those are fairly basic OFFICE-COMPUTERS). 😀

That said ... A high-quality Modular one (like upper-series Corsair or SeaSonic). Even though it's a Mini-Tower, still not very big, so ...

... biggest one that will fit ... I'm guessing around 750w or so.

Re: Max Optiplex 3020 MT build with a standard PSU

mine runs any GPU made..

 

8000 others too.

no thing new here.

 

have 750 PSU, now. 62amps on the 12v rail, single rail. Corsair.

Re: Max Optiplex 3020 MT build with a standard PSU

yes ssd, all you want in fact, only limited by number of SATA Power cables and ports, they sell SATA port cards.

HDD, use 3 amps max to start up and way way less running.. the datasheet on your HDD tells all this, if you look.

ssd had no motor so no startup surge at all.

there is no real limits. if you have good PSU,.

non on the 3020MT,  I have tried every way possible to make it mess up and just will not. 750watt PSU.

you can also buy external HDD, or SSD enclose, and run USB-C (I have one) and turns fast.

and you can add more USB ports if lacking, so with USB and SATA ports out the gills  there is no limit.

the other limit is 2TB limit if booting to MBR,. so don't, and nolimit on non boot hdd or SSD even 16TB with GPT formatted.

ask more questions, most will be yes, yes, then yes.
