the PC has speedstep there is no need for a lower power CPU, not with that wonder,.... use it trust it.

i tried hard to find the dell new sold new options pages but could not..  we could use the waybackmachine.com

but Im too lazy today to find old DELL sales pages. and offered options.

IS THIS  THE FULL SIZED MT?   no CASE size told and no MOBO P/n. dell.

AIO, SFF ? what PC is this, I can never guess, and answers will be wrong making anyone guess, ok?

there is only 2 answers

Dells answer, and they do not have QVL list  but the users guide tells you what they shipped new. clear as day.

NO dell does no test all potential CPU,s, ever see the list of that< huge, and wow ,and hard long work.

2: number to is what 1000s of others did seen on the top benchmark sites. ever look there, first,. I WOULD.

hint 1 , upgrade bios first or it CAN FAIL.

the 5 th hit there lands on 6700.

te and T are low power, why pick those and invite BIOS to fail them, why not pick the fastest I7-6xxx the runs here and not go over Power limits..

why not go 6700 , plain?  why not? use what others used, there is no dell QVL list,

only this, thing.

dell shows zero answers under CRU, rules , customer replaceable units,  NO CPU  shown there.

3.2GHz Intel Core i5-6500 quad-core processor (came new like this no?)

now a 3rd way, learn to shop REFURBS,  many are in fact upgraded. to I7 even 6700

see this

and this MT

Thanks for the info up till now!

1. It is SFF

2. The current i5 6500 is showed as 65 watts TDP, the standard i7 6700 is shown as well as that much. But I would like to lower the power consumption and to bring the case temps down a bit, without losing too much power, so I can install GTX 1650 Low Profile in it, which draws more power. 

I really appreciate your help and the effort you have put in these answers!

SFF systems DO NOT SUPPORT 75W video cards.

you can try radeon wx4100 or yeston Rx550 single slot gpu

if want gtx you upgrade 180 watt psu to 235  watt psu
