How to ground PSU without the screws?

post #1 of 5
Thread Starter 
Hi,

I'm currently working on a new build and made a slight mistake with the clearance for the PSU so I had two options, turn it around or put it upside down, the one I have is fanless so I can't put it upside down, forcing me to turn it around horizontally (Fractal Node 304 so the PSU is completely inside the case, not even the back is accessible from outside the case). The problem now is that I can only put one screw in. I assume that means it's not really grounded, and so was wondering if I need to ground it with another grounding wire screwed into the case and the PSU? Also, would it be as safe as mounting it normally?

thanks!

You're not grounding the PSU. It's already grounded through the third prong on it's power cord. What you're doing is making sure there is no voltage potential between the case (and anything else "grounded" to the case) and the PSU.

There's no reason not to add a separate grounding wire though.

Ok thanks, is one enough or should I put 2 or even 3?

also, I dont know anything about electricity but what would be the risk of that 'voltage potential'?

thanks!

I just realised that the one screw holding the psu isn't even touching the metal piece that is usually behind the regular PSU mounting holes since it's not an "official" mounting hole so I guess it's pretty useless.

Here's what I did, is that good enough?

Yes, those are the connections you want to make but you could do better
