Using with a Dell Inspiron 3670 - needs a 24-pin to 8-pin adapter
David C. Rose✓ Verified Purchase•October 14, 2023
Dell Inspiron 3670 i7 8th Generation are sprightly mid-range business machines that offer very good bang for buck as far as performance but, and it is a big BUT, Dell really, really don't want you to extend their use outside of business.
My need was for a machine that would happily work Davinci Resolve video editing. I used a Geforce 6GB GPU for the video crunching, but to do so I had to add an external power supply and ditch the on-board PSU for the Dell. There are NO spare power taps on the 3670 - no supplementary power for cards or additional drives. The ATX mobo connection is also special which means you can't use the 24-pin ATX connector that comes with the Corsair.
You must separately get a 24-pin to 8-Pin adapter to power the mobo, and then take the 6-pin CPU connector from the Corsair to the CPU socket on the mobo. This worked for me: https://www.amazon.com/gp/product/B01A210HKO and there are others available
Then you have power to the GPU, and power for a second drive (so I could switch to an SSD plus the original HDD as a data store) plus power to a USB3 card for my external data stores..
The new PSU sits on top of the case, and snakes in through the remaining slot access - not to everyone's taste - but it all works very happily and is almost silent. I retained the original PSU and connectors so I can reverse this out for a vanilla machine at a later date. It voids the warranty from Dell, of course, but if you cared about that then you wouldn't be here. Good luck.

Let me start by saying, I know almost nothing about building computers so I was quite unsure how to go about this. I was having problems with my old PC and was told that one of the most likely issues might be the power supply. After some consideration and suggestions by friends, I got this model. I was surprised at how easy it was to actually install the thing (at least just the PS). All I can say is that it worked just as advertised. Sadly we found out later on that the PS was not the issue.
Solid power supply, clean wiring

I originally purchased the Corsair GS 700. They bill that model as a gaming PSU. Once installed, the PSU made a chirping noise (like a hard drive read/writing, but at a higher pitch). After searching youtube and reading more on the Corsair forums, I found this was a widespread "issue" with the GS 700. The GS model "features" a "smart" fan, which only runs when the load/temperature demands it. What I found is the fan was confused if it should run or not (attempting to kick on, chirping noise, kicking on and it running fine, then back to attempting to kick on and chirping).
When asking about this on Corsair's forums, they recommended an RMA for the same unit. Based on the many youtube videos documenting this noise and the numerous posts around this, I simply returned my unit to Best Buy for a full refund.
In looking into the Corsair models more, the CX is a lower model PSU. Anything above the CX model has the "smart" fan, which I did not want. This led me to this model.
- Great power supply
- Features a constantly running fan (at variable speeds depending on load/temp)
- Modular cabling, which allows for clean cable runs and reduces unneeded wires
- Low noise even with fan constantly running, even at higher loads/temps
While they tout the "smart" fan as a feature, for a gaming rig, I look at it as a drawback. The more airflow, the better.
I have been impressed with CX series and have not had any issues with the PSU. It is structually sound and appears solidly built. Highly recommend this unit to anyone looking for more power in their PC.
