Dell Optiplex 7070 MT GPU Upgrade

You should not ignore the power .

Bare minimum working is evga 700BR based on 24 amps for 3.3v and 150W COMBINED for 3,3v/5v rails

You need moddiy adapter to use power supply outside the case.

the combined power required is why the B2 B3 BQ N1 W1 versions from the same vendor do not work. its also why the 600br is not acceptable nor is the 450br etc

SIZE is an issue in the 7070 because the MT is smaller than a real tower.

Cards longer than 8 inches do not fit in the case.

Graphic card is too weak for this processor:

Intel Core i7-9700 (Clock speed at 115%) with NVIDIA GeForce RTX 2060 (Clock speed at 100%) x1 will produce 15.83% of bottleneck. Everything over 10% is considered as bottleneck.

Graphic card and processor will work great together

Intel Core i7-9700 (Clock speed at 100%) with NVIDIA GeForce GTX 1660 Ti (Mobile) (Clock speed at 100%) x2 will produce only 1.13% of bottleneck.  The catch?  I still don't know what "mobile" is supposed to mean.  At least 32GB RAM is recommended.

Graphic card is too weak for this processor:

Intel Core i7-9700 (Clock speed at 100%) with NVIDIA GeForce GTX 1660 (Clock speed at 100%) x1 will produce 23.31% of bottleneck. Everything over 10% is considered as bottleneck.  We recommend you to replace NVIDIA GeForce GTX 1660 with NVIDIA GeForce GTX 1080 Ti.

Graphic card and processor will work great together:

Intel Core i7-9700 (Clock speed at 105%) with NVIDIA GeForce GTX 1080 Ti (Clock speed at 115%) x1 will produce only 0.21% of bottleneck.  At least 32GB RAM is recommended.

The above quotes come from PC Builds.  I couldn't it to pull up the GTX 1660 Super.

As for the GPU's with the least amount of bottleneck, of course, this is granted the PSU is upgraded as speedstep suggested.  As long as one is comfortable with PSU outside the case.

Images will appear when approvered by moderation:

 NVIDIA GeForce GTX 1080 Ti is not ever fitting into 7070 case.

thats bad advice

 1080 ti used in video was installed into xps400 from 2006.

1080 ti needs 850W power supply.

1080 in video is in 2006 xps 400 tower

12 inch card

@speedstep,  Saying "That's bad advice," usually in big red letters, whenever you disagree with someone is callous.  You still can't make corrections without it.

Yes, @speedstep, whenever you know something somebody else didn't, you always handle it so well.  I didn't say I wasn't wrong.  I see your response came in while I was typing another reply.

There's a difference between saying "That's bad advice" and "Did you know...?

You've gotten numbers wrong before.  Instead of saying "That's bad advice" in bold letters, I simply made the correction, sometimes with a screengrab from a manual or other source.

What speedstep did right is a 12 in. card won't fit.  There's a 267mm version of it which is shorter, but that's still 10.5".  As speedstep said, 8" is the max to fit in a 7070.

Speedstep and I probably won't agree on PSU's.  Nvidia and GeForce recommend 600w PSU's; screengrabs below.  Speedstep normally recommends 750w PSU's so there's enough power on the 3.3v/5v rails.  I get that.  However, I wasn't expecting a recommendation of 850w.

Some good news...  You already have a great CPU with UHD graphics.  Intel's UHD Graphics 630 IGP operating at 350 MHz with a burst frequency of 1.2 GHz.

I use red to indicate negative and always use big letters.

Telling someone a 12 inch 3 fan card is recommended when no such thing works or physically fits into the case is bad advice.  Complaining that its not bad advice doesnt change the fact that both the power supply and the physical size of the card prevent 1080TI from EVER being used.

Callus is telling people they can buy a $700 video card that they will find does not fit at all in the case and the power supply does not work at all for.

1080 ti needs 850W power supply

850w is based on current DELL power supply model used in systems that have a 1080TI which you recommended Brad.

There are 850W units that are not to Dell spec based on the EPS12V and the 3.3V/5V combined power spec.

DELL 460W unit has more power on 3.3V/5V rails than 850w SEASONIC.

All rails count.  POWER SUPPLIES are not a single spec of WATTS.

Note 3.3v goes UP to 30 AMPS and 5v GOES UP to 32 AMPS 160W with combined power of 225W for that rail set on the Dell 875W unit used in Alienware and Precision Models that support the 1080TI.

W299G 875w Delta

W299G uses specific WIRING HARNESS R166H

Dell N1WJD 48Y6D Alienware Aurora R5 R6 Model Numbers: D850EF-00, DPS-850AB-2A, 0N1WJD, 048Y6D

N1WJD is modular so it uses many cables not a single wiring harness like the 875 used.

"There's a difference between saying "That's bad advice" and "Did you know...?"

The passive aggressive rarely takes responsibility for giving incorrect bad advice. Requiring me to Validate something is correct when its ALWAYS wrong is playing the victim. I am not accountable for your choices nor should I be.

It changes nothing. Telling someone a $700 card that will never fit in the case is bad advice.

This has not changed.

Telling someone that a card that requires 850W power supply is recommended when the unit has 260W power supply standard and no option for a larger one is bad advice.

This has not changed.

Recommendation of the GTX 1080 ti was retracted when I also said it wouldn't fit.  Lord speedy failed to see that and notice I said he was right about the length.

@speedstep, lord speedy,

You still don't get it.  After somebody has admitted they were wrong about something, you still callously go on and on as if they didn't.  This has not changed.  When it came to that link which turned out to be in error, AFTER I requested it be removed, AFTER I apologized for it, you callously went on about it with no acknowledgement of the aforementioned whatsoever.  According to your statements, this will not change.

AFTER I admitted my wrong, you have the false assumption that I somehow required you validate my error and "playing victim."  So where's the quote?  Assumptions always make both parties involved look like a you know what.

"Telling someone that a card that requires 850W power supply is recommended when the unit has 260W power supply standard and no option for a larger one is bad advice.

This has not changed."

YOU were the one to recommend an 850w watt PSU.  "1080 ti needs 850W power supply." - speedstep  Yet somehow I recommended it and now it's not good enough?  Screengrab will be below.  "no option for a larger one" is your words only.  Upgraded PSU having to be outside the case was already mentioned and images posted.

Here's how it could've gone following my positive suggestion.  Speedstep - "Did you know that the GTX 1080 ti is too long to fit in a 7070?  Did you also know it requires an 850w PSU?"  I would've said, "No, but thanks for the correction, and good catch.  I know it needs a higher watt PSU.  By the way, Nvidia and GeForce recommend 600 watt PSU's.  But that does that really matter since the GTX 1080 ti won't fit anyway?"  Your response?  Possibly to effect of "For future reference, the GTX 1080 ti needs a 850 watt [or is it 875w?] PSU."  And then you could've gone on with your reasoning.  Also, in turn, I'll want to make improvements before suggesting certain cards like the GTX 1080 ti.

It isn't just about facts and never admitting if your wrong or could improve.  Correcting people the right way can get "thank you"'s and much less argument, if any.  I know you don't use "thank you"'s or anything for a compliment that can go a long way, but I do.

We're human.  An occasional mistake in inevitable.  But redxps630 and I knew how to correct each other on such an occasion, so on and so forth with some others also.

"YOU were the one to recommend an 850w watt PSU. "1080 ti needs 850W power supply." - speedstep Yet somehow I recommended it and now it's not good enough?"

I mention the 850W Dell power supply due to it being used in models that have a 1080 TI.  Alienware and Precision Models that have a 1080TI in them or can use a 1080TI also have a N1WJD 850W power supply.

Telling a user that their 260W unit should have a 1080 TI that will never fit into the case is the issue.  Taking snippets out of context does not mean that I recommended an 850W power supply for 7070 tower.  The reason is simple. It will never fit into the case so there is no point.

You also routinely recommend a power supply based on a single spec of watts and claim that if Watts is good enough it should work.  I have documented a seasonic 850W power supply that is not as good as a Dell 460W power supply because it does not meet specifications for 3.3v/5v rails, as well as combined power for 3.3v/5v rails.   This too has not changed and completely disproves your statement that (we may not agree on what is the correct power supply.)  All rails count.   Power supplies are not a single spec of WATTS and have a single rail of 12v.  The 3.3v/5v and 5vsb rails matter.  The overall power matters meaning if you use 150W from a 450W power supply on the 3.3v/5v rails you DO NOT HAVE more than 280W left for the rest of the system. 

To recommend a 1080 TI"  that is the problem and its not my problem.  You don't speak for others in dell or outside of dell so I'm not sure where we comes from. Especially when giving bad advice recommending a $700 video card that will never work in a 7070.

If you post bad advice and you do not know what the correct answer is YOU are responsible for that. That its wrong and bad advice has not and will not change.  You insist because you don't like the fact of wrong answer and bad advice that I have to figure out intent to post bad advice.  This is passive agresssive playing the victim.  I am not responsible or accountable to figure out if your choice to post bad advice was intentional or not. This is never the case.

Complaining that I should change "bad advice" to something else because its callous is passive agresssive playing the victim.  The fact of the post being wrong to recommend using a 1080 TI in an Optiplex 7070 is bad advice will not ever change.

SEASONIC 850 vs DELL 460WEPS12v Why the other rails matter

You post that "WE

@speedstep,

"You also routinely recommend a power supply based on a single spec of watts and claim that if Watts is good enough it should work." - FALSE NONSENSE and you know it.

As for your referring to "We recommend..."  You missed in that post "The above quotes come from PC Builds."  Just a snippit taken out of context.

"Telling a user that their 260W unit should have a 1080 TI that will never fit into the case is the issue.  Taking snippets out of context..."  Exactly what you just did.

Most of your post is old news and was already responded to.

You've used comments like "That's bad advice" and callously "That's nonsense" on others also.  You act as if there's no better way in spite of constructive criticism showing a more positive example.  You also act as if there's purposeful intent if someone is wrong, or if you think they're wrong.

Some people might not say anything, but if they assert, you call them "passive aggressive."  Are you a psychiatrist?  (If so, you're a lousy one at that.)

So go ahead and label me "passive aggressive" while on your high horse.  Do another hostile post about what I said or suggested and was retracted.  My points still stand.

This argument needed to end before it started and I'm done with it.  It's not what Dell users are out to see.

"You also routinely recommend a power supply based on a single spec of watts and claim that if Watts is good enough it should work." - FALSE NONSENSE and you know it.

This is delberate false statement on your part. 

I have never recommended based on the spec of watts.  I reference EPS12v and Combined power all the time. 

What I have noted in both pictures and spec and words is the 3.3v/5v COMBINED max power must be at least

150W.  It can be more but being less is why a unit with the same WATTS rating is not acceptable.

750BR 750B1 is fine But B2 B3 BQ N1 W1 models from the SAME VENDOR is not ok because the combined power max for 3.3v/5v rails is 90 to 130W.

This spec was raised several times in the EPS12v specification to address problems.

Dell changed the AMPS on 3.3v to 30AMPS for 3.3v and 32AMPS for 5v with Max combined 225W.

My recommendations are based on BARE MINIMUM required.

Watts doesnt cut it when you have a very low max power and AMPS for the 3.3v/5v rails and 5vSB.

SEASONIC 850W unit is not as good as DELL 460W unit and up.

""Telling a user that their 260W unit should have a 1080 TI that will never fit into the case is the issue. "

No this is not an issue its Fact that a 7070 only has 260W power supply and 1080TI will NEVER fit into the case.  No amount of complaining will change this fact.

ALL RAILS MATTERSEASONIC 850W VS DELL 460WDELL 875W has 30 AMPS 3.3v and 32 AMPS 5v

Hello, I am coming out of this post because I am in a bit of the same situation (please forgive me for the writing, I use the online translator), and as finally there was no conclusion to this post, voila I have an optiplex 7070mt (I7-9700-260W-GPU GT 730 power supply ....) and that's the problem the GT 730 GPU is really insufficient, so I would like to change the power supply for a more powerful one. 'outside the PC this is not a problem for me, using the famous "moddiy 6/24 pin" connector but I do not want to burn the motherboard of course, for the power supply I was treating "EVGA or Corsair ... "(corsair SF is no longer available at home and I don't know which other category to choose: AX, HX, RM, TX, CX ...) (I find an EVGA BR 700W available) (EVGA B1 750 is unavailable at home) finally why advise you "BR and B1" for food, what does it correspond to?

for the GPU, well if the RTX 2070 super or 3060 could power up it would be the top.
