Re: Inspiron 3670, PSU upgrade

Jump to solution

That is an interesting mod. I bought the 3670 based on the overall spec but there was no option to upgrade the video at time of purchase. I thought I have a FreeSync monitor which requires an AMD card to get the freesync to work. Which means that even the Dell 365w PSU will not be enough to drive it.  So I would need to do the mod you did to get an aftermarket psu to work..

I don’t know how much modding you had to do to get the PSU to fit. What was that board with the wires soldered on? Is that part of the mod?  And you need a 24 to 8pin adapter. Correct?

In addition I assume that is the sapphire short GTX1060 card installed? I need to know how much more length is available in the case. I believe the sapphire card is 7.2 inches. I found an RX 570 CARD (gigabyte AORUS) that is 9.1 inches. Do you think there is room.? My system has not arrived yet and I want to get the parts ordered so appreciate your input.

  The board you see is the adapter you’ll need for the PSU. It adds a line back to the PSU to signal all is good an power up. Also sends the motherboard proper voltage it needs to sense so it can also say all is good. At the time when I ordered this there wasn’t any adapter labeling itself for a Inspiron 3670. So don’t get nervous if you don’t find one that says exactly for a 3670 as this one is compatible. 

  For your monitor goes, I don’t have any input for you. I have mine running to a 65” led for the monitor. 

  The GPU that you see is a 1050 TI. The measurements I have are.  OD between the case walls where GPU lays are 10 5/8”. From the very front point of GPU to the 8pin I have a tolerance if 1 1/8”. From end to end of the card I have an OD of 9 1/2” . Before I received the adapter for PSU, I tried to do it without. I was successful in doing this. So it is possible to do without. I want to say I jumped off the mini 6 pin by using the 5v leg. At 2am, a roll of electric tape, an a rats nest of a never ending rainbow of connections I forgot what went were after disassembling all of it to make its final connection. So if you’re just as impatient as me waiting for the adapter to show up an itching to stuff all your new toys in it, well  then it is doable to do with a meter an some electrical knowledge. I hope this helps you some. An if you any other questions please fell to ask me. Hope it all goes smoothly for you. An remember with a few beers an a hammer you’ll have all the room you need to stuff whatever graphics card you wish to install lol.

Depending on your PSU you might have to trim a very little. This is due to the outer black ring around the plug in receptacle. The EVGA 600w i did I trimmed a tiny bit ; by making two slits an bending along the stamp line with a pair of pliers. Don’t just bend it back because this will not give you length you’ll need to secure the PSU all the way  down.

Wow thanks for all the details! Was kind of about to give up on an AMD solution and go with the GTX 1060 and upgraded dell PSU. Now that I know your card is 9.5 inches and it fit then the 9.1 inch Gigabyte AORUS (AMD RX 570) should as well. Thanks again 

I can’t say I have great electrical knowledge (or time) so I can’t undertake soldering that board together but from what I understood earlier that adapter would do it. Assuming I buy the adapter recommended would that work with the PSU you bought or is the circuit board mod also necessary? I am going to go back and re~read about that adapter.

I kind of like the idea of a better PSU as I have another 240GB SSD in my previous machine I would like to add plus a much larger conventional HHD. Looking at the mobo diagram I get the sense that it only has connectors to power two hard drives? Maybe there are splitters after the motherboard connectors?

Either way a good PSU is never a bad thing when it comes to overall stability and longevity so probably worth while. Besides, good enough is rarely satisfying if you can make it better.

After some more thought I am going to go with the Dell 365W PS and recommended GTX 1060 card. This keeps me in the tested and approved to work category and I just have time to rewire the whole system and make cuts to the box etc. Keep is simple it best for me right now but thank you for the input. A good head start here for anyone that may want to go that route in the future. 

Best,

Kringle.

Re: Inspiron 3670, PSU upgrade

I have installed a Asus GTX 1050 Ti card that fits the Inspiron 3670 w/o need for any additional connectors at all from the PSU. It gets its power directly from the motherboard. I was looking to upgrade from the standard 290W power supply but I see that Dell offers (it did offer) a 1050 Ti card with the 290W power supply unit. No need to screw around with any mods. My only problem is that I still can't get the board to recognize the new card, even after disabling the onboard graphics, disabling security settings, etc. Not to hijack this thread, but looking for help to get the card working.

They DID NOT OFFER it with 290W and 1050TI or any other 75W or greater card.

Those units have optional 365W power supply.

Even NVIDIA says 300W minimum for 1050 or 1050TI.

 

When installing an after-market graphics card into a Windows PC with UEFI secure boot enabled, the system may not boot.  This is true for ANY PC not just Dell.

OK, I must have misread their specs listing. Can I purchase the 365W PSU from Dell and just install it? I've been searching for it and don't see it . I hate calling them since no one there seems to speak English.

If dell is still selling the 3670 then the power supply should be available from spare parts.  The Dell GT1030 works without needing a power supply upgrade.  PNY GT1030 also works but requires Secure Boot OFF and Legacy Option Roms ON.

There are other vendors that carry the 365W power supply.

Re: Inspiron 3670, PSU upgrade

Thanks for the suggestion. I did go online and have a chat with a sales specialist and she (think it was a she) found the 365W PSU in their spare parts book, which is not visible on line. I ordered one and have it should be here Friday. I have done all of the bios changes and still get no signal from my card so I can only assume that there is just not enough power. If the 365 doesn't work along with all of the bios changes, I may have a dead card but the fans work so I know its getting power. Anything else I should be looking at? I have seated and reseated it several times to make sure it was seated, fans always working, tabs always fully seated.  Again, thanks for the spare parts suggestion.
