Recommendation on Power supply/PSU

[Roland_001]

Hi all,

So I've mostly finished my MAME+Mister cabinet.  I'm fairly new to all of this (especially the eletornic stuff), but have somehow managed to create functioning sytem, which requires various 5V and 12V components. Currently, I have an ungainly series of USB blocks, and individual 5V and 12V power bricks.  I'm not using JAMA parts (No arcade PCB's, etc.).  So I don't think I'll need a -5V power supply (not really sure what that is, but seems to be a thing in traditional Arcade machines?).

I recently discovered that there are dedicated PSU's for arcade, and it seems like many people just use left-over PC PSU's and strip the 5V and 12V MOLEX wires to power their arcade.

For many reasons (less clutter, fewer points of failure, better cable management, etc.) I'd like to consider a solution like that rather than the multiple individual power bricks/adapters I'm currently using.

On Amazon, I see two general styles, as shown below.  I'm not sure of the pros/cons to either one? 

Type 1 (Sold as "For arcade machines"):

And type 2 (just generic 5V 12V 24V Power Switching PSU):

Finally, I have an old left-over modular PC PSU:

For the modular PSU, I'm not sure if I have the cables it came with, and from I understand, these are often proprietary.  But presumably, if I can dig them up, would that be the best choice?

Thank you for any/all help.

Are you planning on using a switched IEC inlet to apply power to your system?



Type 1:
Pros - Small footprint, mounting screw holes, easy to wire to a switched IEC inlet, and it is automatically on when power is applied.
Cons - Taller profile exerts greater torque on mounting screws if the upper part of the PSU is bumped sideways.

Type 2:
Pros - Lower profile, easy to wire to a switched IEC inlet, and it is automatically on when power is applied.
Cons - Looks like there's one mounting screw hole in the front and several on the side.  Is there one in the back?  May need to add L-brackets or plumbing strap to mount it securely.

Type 3:
This type of PSU seems like overkill.   

If the cables are missing, I wouldn't invest the time/effort.  YMMV.
