And more importantly, what have you done so far?

snow jay Mar 10, 2023, 9:54 PM

haughty slate Mar 10, 2023, 9:56 PM

#

snow jay Mar 10, 2023, 9:57 PM

How would I know if they're onsided or not?

haughty slate Mar 10, 2023, 9:57 PM

#

#

on the otherside of the cables should be a name

snow jay Mar 10, 2023, 9:57 PM

#

Yes I mean I hooked them up to where I believe they should go.

haughty slate Mar 10, 2023, 9:57 PM

sofar so good 🤔 was hopen it was one directional

#

how do you turn on the pc? are you using the pin technique?

snow jay Mar 10, 2023, 10:00 PM

#

That's the plan, unless I'm doing it wrong it's just placing the screwdriver on the pwr pins right?

haughty slate Mar 10, 2023, 10:01 PM

#

yep

#

If nothing is responding also check the backside of the PSU , for the power switch?

#

if its turned on?

snow jay Mar 10, 2023, 10:02 PM

#

Yeah it's on, I've also switched outlets too

haughty slate Mar 10, 2023, 10:02 PM

#

oh you got 2 MOBO cables?

snow jay Mar 10, 2023, 10:02 PM

#

No I mean the cable that plugs it to my grid

haughty slate Mar 10, 2023, 10:03 PM

#

yeah , just going on my own thread.

#

as in , I see 2 MOBO cables, one is loosse

#

and one is inside the PSU

#

can you switch them around?

#

and try again?

#

haughty slate Mar 10, 2023, 10:07 PM

#

Memory is 4800 MHZ

#

snow jay Mar 10, 2023, 10:07 PM

#

You think it's safe to install windows now or should I water until it's in a case?

haughty slate Mar 10, 2023, 10:07 PM

#

#

whatever you want 🤷‍♂️

snow jay Mar 10, 2023, 10:08 PM

haughty slate Mar 10, 2023, 10:08 PM

#

best bet , is to build it in first though

snow jay Mar 10, 2023, 10:08 PM

#

Apparently I need to do it for my GPU

haughty slate Mar 10, 2023, 10:09 PM
