Dell 635W PSU has 8 pin PCIE . I need 8 + 6 pin PCIE. Can I use this splitter

falaktheoptimist · Jul 25, 2017

I have a Dell machine with 635W PSU (Datasheet: https://plugloadsolutions.com/psu_reports/DELL_D635EF-00_ECOS%202543_635W_Report.pdf). It has got an 8 pin PCIE splot. I have a Titan X GPU which needs 8+6 pin PCIE power inputs. I found this splitter on Amazon: http://www.amazon.in/PCI-Express-Video-Y-Splitter-Adapter-Supply/dp/B00A3OVG4W Can I use this to put into the 2 GPU PCIE slots without any problems?

Yeah assuming your current PSU has enough amps on the 12v rail.

RobCrezz :

How do I determine that?

falaktheoptimist :

Check the label on the side of the psu, look at where it says 12v and how many amps.

You need at least 40amps on the 12v rail in my opinion.

Here's the datasheet: https://plugloadsolutions.com/psu_reports/DELL_D635EF-00_ECOS%202543_635W_Report.pdf So. I'm guessing it should work.. Thanks!

that PSU is not good enough by a long shot

only has a max of 12V/18A

It's it 51 A as far as I can understand: https://plugloadsolutions.com/psu_reports/DELL_D635EF-00_ECOS%202543_635W_Report.pdf or am I missing something?

Output +12VA---18.0A ， +12VB---18.0A， +12VC---18.0A， +12VD---18.0A， +12VE---18.0A， -12V---0.5A， +5VSB---4.0A

Sorry for being such a PSU dummy, but do we need a PSU which has >40A on a single 12V Output? Or the aggregate number at 100% load as mentioned at: https://plugloadsolutions.com/psu_reports/DELL_D635EF-00_ECOS%202543_635W_Report.pdf ?

Im not exactly familiar with that PSU, but ideally you want all the 12v amps on one rail, as you are going to be drawing a lot of ampage from one connection.

blockhead78 · Jul 25, 2017

you're looking for a PSU with a rating [+12V 40A] or higher on a the 12V rail

falaktheoptimist · Jul 25, 2017

Wold this one work for me then: https://plugloadsolutions.com/psu_reports/DELL,INC_D685EF-00_685W_ECOS%203467_Report.pdf? I'm really confused about which PSU to go with at this point. And we've all Dell PCs with Dell having it's propreitary PSUs so, not much hope of digging/ modification in there.

blockhead78 · Jul 25, 2017

it's not up to spec

you need a PSU that can deliver more amps on a single +12V rail

If you're stuck with only being able to choose from Dell PSUs because of compatibility, then you might be stuck. I'm not 100% sure on that though
