Upgrading GPU and PSU for Optiplex 9020, baffled by 8 pin connector. !!!

Hi, I have a gaming related question if you will.

I recently aquired a brand new 9020, was amazed by the performance and was eagerly anticipated putting in my old Redeon HD 5770. However, I was confronted by the issue of the connectors on the motherbioard being unfamiliar and non-standard. My old 650w SPU had a  4pin to 8pin connector, much like your stupid motherboards, but they do not reach. The expected 20"-24" pin connectors were nowhere to be seen, so I could not use those either. Have I just made a oversight and that my Huntkey Titan 650 psu simply needs an extension lead to reach the motherboard socket, or am I screwed? The PC was bought for me by my university and I had no choice of the specs.

Very best

Dell isn't the only one doing this.  HP also does this.  Its likely a response to power supplies being swapped with counterfeit units.

The adapter looks interesting.

Dell OptiPlex 3020 PSU Main Power 24-Pin to 8-Pin Adapter Cable.

Suitable for Dell OptiPlex 3020 / 7020 / 9020 / T1700

Seems to be using the Grey PWR Good, 3 Black Ground Wires, The Power On/Off Green Wire, the 2 12V Wires from the 24 pin and 1 12v Wire from a molex power connection.

That means that I can hack myself a power setup using the original power supply cable and some heat-shrink and solder.

The  OptiPlex 9020 MT supports/requires a Dell proprietary 290w power supply, a standard ATX power with 20/24-pin main motherboard power connectors are not compatible, there no compatible retail power supplies available.

You happen to know why Dell chose for this option other than maybe lower building costs?

Personally I find this move beyond stupidity, and for the Dell people maybe also reading this, yes I will not recommend dell to friends anymore just because of this.

All prior Dell models like 7010, 790, 780 even GX620 used standard power supplies, that could be swapped out by other, moer powerful standard power supplies when you added a graphics card.

Now Dell has removed that option. Not good.

I have no idea why this is happening, but recently Dell seem to be moving towards using more proprietary components.

Shades of around 14+- years ago, when Dell desktop power supplies were all proprietary units.

Also, many Dell laptops now have the processors soldered onto the motherboards, that does not allow you to upgrade them, unless the motherboard is replaced together with the processor, making the upgrade exorbitantly expensive.

I have a Dell Series 7000/7537, that has a motherboard with an 'in situ' processor, thankfully I knew about this and purchased the laptop with the Quad 4 i5, instead of the i3 processor.

Yeah, it kinda sucks, although I am planning to still upgrade it all once I become more affluent. Remove the old Dell mobo, case and PSU, take that 8GB RAM and i7 and put it in a new machine with a decent graphics card. I use the PC for gaming a lot and it run Planetside 2  at around 30-50fps on low settings @ 1024x768, it's been enough to be honest, I'm just glad I didn't buy it with my own money. The i7 is such a beast, if you remove the GPU it comes with, the Intel 4600 series built in GPU is more powerful, especially if you overclock it, although it's something you can't do very well still given that Dell have gone proprietary crazy.

Ok, hold on and please consider that you will lose your Windows 7 or 8 license after replacing the Dell motherboard. Maybe better to sell the 9020 and buy a new CPU and memory with the new mobo, case and PSU?

Good spot. Damn you, Dell!

Yeah same issue here trying to add a new GTX 970 to it, power supply has no extra power connectors available to connect to vidcard. Amazing Dell! Amazing! Pay $1000 for a pc that has not one extra power connector.

This tells us Dell offers you 0 upgradability.

The Moddiy Adapter changes the picture.:emotion-2:

August 31st, 2015 17:00

Confirmed as a work-around. Tried it out, tested voltages with meter. No problems have appeared, was able to insert a 500W PSU to run an R7 250X. One thing to note: the adapter I received did not have the 4pin molex attached, instead it utilized the 12v by having two cables in one pin

i can confirm the moddiy adapter works. i installed a 600 psu with this adapter and a gtx 970 and its working fine.

I can also confirm that the adapter works. That's as much as I can say, as I don't know anything about voltages. But it lets me use my 500W PSU and the graphics card that required the extra power, so I'm thrilled. I will soon be penning a love letter to modDIY. ;-)

Andulamb, what (if anything) did you use to get power to the 4-pin port on the motherboard? I got the adapter and connected to my 8-pin but don't have anything to get on that 4. I went ahead and tried to boot without the 4-pin connected and it gave me brief power but won't fully boot up the PC.

Your replacement power supply should have a separate 4 pin cable that you can connect, no adapter needed for that.
