hullo...

 

i am in the process of replacing the stock PSU on a Dell 3668 with a Corsair CX500...i realize that the Corsair will be resting on the outside of the case, as there is no room for it inside the mini-tower...on the stock motherboard, the PSU plugs into two places, the ATX 1-CPU (4 pin) and the ATX 2-SYSTEM (6 pin)...the question being, with the Corsair CX500, do i use a 24 pin to 6 pin adapter for the ATX 2-SYSTEM and then the 4x2 cable for the ATX-1 CPU?  i am doing this so as to add a GTX 1050Ti GPU...the stock PSU is 240W, which is supposedly fine for the 1050Ti, but i just want to make sure that there is enough power...the 1050Ti does not use a 6 pin connector...

 

any help would be most welcome...

 

bests,

I meant Dell stock one.

Also full specs about that Dell may help. As that stock PSU might be enough. I might guess what those ATX 1-CPU (4 pin) and the ATX 2-SYSTEM (6 pin) connectors are but pictures about them could also help.

That 24 to 6 pin adapter sounds quite strange IMO.

This pdf may help.

Page 16 does show a 6pin power connector.

Wonder if the same 6pin that connects to graphics cards would be the same configuation.

i also spoke with Dell tech support and they confirmed it. They also stated that the power supply cannot be upgraded above 240 watts, and the 6 pin power connector on the motherboard is not PCIe, so I had to return this PC


OEM machines suck again.

Not really in the case of a full size OEM desktop computer most all aftermarket power supplies would have fit inside the case perfectly.

 

Just the small form factor OEM desktop computers as most components used if not all are proprietary and that always a no win bummer.

busy two weeks...will post picture of OEM PSU, but i think i am stuck with what i got...returning will be up to $100 and thats not an option...silver lining: the GPU (GeForce GTX 1050Ti) will work perfectly with current system i have...not a heavy gamer and i am adding nothing else to my setup...it pulls only 75W from MB...

thanks very much for all the help and time you have taken on this...

stay safe...

If you have a 300 watt power supply you will be OK.

What I saw on Dell spec sheet on your computer you have a 260 watt power supply.

 

On Nvidia website recommended power supply is 300watt.

 

https://www.nvidia.com/en-us/geforce/products/10series/geforce-gtx-1050/

 

https://www.geforce.com/hardware/desktop-gpus/geforce-gtx-1050-ti/specifications

 

I would make sure before buying or using the graphics card.

And? Graphic card manufacturers' power supply "recommendations" are always useless.

Maximum Graphics Card Power (W) 75


So why is minimum PSU 300W? Because rest of the system consumes at least 200 watts? How do they know that? They don't.

Graphic card manufacturers' power supply "recommendations" are usually the minimum amount needed for satisfactory performance.

I don't think the 24 pin to 6 pin adapter will work. There are adapters for 24pin to 8 pin Dell MBs but according to this Dell thread the 6pin is not PCIe.

Really? I have seen desktops with 65W PSU. 65W+75W = 140W. Less than half of 300W.
