Two missing pins on OEM 24-pin ATX power supply connector

HP Recommended
Envy 750-625rz
Microsoft Windows 10 (64-bit)

The 24-pin ATX motherboard connector from the original 300w power supply is missing two pins, specifically pins #14 and #20.  These are used for -5v and -12v.  I've read that the -5v was phased out after 2003 or so, so it's very common for this one to be missing, and both replacement 500w power supplies I've purchased recently have had pin #20 (-5v) missing.  However, both of them have pin #14 (-12v).  Do I need to remove this pin from the connector, since the original did not have it?  The first 500w replacement I tried only lasted 5 days, and I don't want this next one to fail also, if this is the cause and I can avoid it.

No.

 

You do not need to remove the pins.

 

Are you  using enthusiast type ATX PSU units or just cheap brands?

 

I have never had a PSU crap out on me, but I  have always sourced and purchased well known brands for my PC builds. 

 

OCZ (doesn't exist any more), Corsair, Seasonic, XFX, Cooler Master, Thermaltake.  

 

Corsair and Seasonic  sell the most reliable PSU products in the consumer (enthusiast) marketplace.

Corsair. ( check out Newegg.com)

Seasonic (also at Newegg.com)

It is third tier, but I am sure that it had a warranty.  Contact the supplier for an RMA to get a replacement or a refund.
