PSU 20pin v 24pin

[jel183\(UK\)]

Hi, some advice please...

I have just put together a barebones bundle and am running XP on a Winfast
motherboard that has a 24 pin psu connection. The supplier sent me the wrong
wattage psu for the bundle and has now sent me the correct wattage but 20
pin psu and an adapter.

Is the use of a 20 > 24 pin adapter ok or should I insist that they supply a
24 pin psu?

Have you tried it to see if it works?.. I understand that it will, but
personally I would use the correct power supply..

Bundled or not. 24 pin needs that same power supply. Unacceptable
otherwise in my opinion.

Some motherboards are designed to accept either 24 pin or 20 pin connectors.
Check your motherboard manual, if it does it will accept the 20 pin in one
orientation only.

For instance, I have the MSI K8N Neo4 Platinum mb, and it will run either
one, and states so in the manual.
I am running my system with an Antec True Power supply, that has a 20 pin
connector, plugged into a 24 pin slot on the mb...

However, I would feel better if I had a 24 pin power supply, if I felt the
need to buy a new power supply today, it would certainly be a 24 pin .
Usually they will be a 20 pin with an extra 4 pin adapter that goes along
beside it.

Thanks for the relpies,

I too am reluctant to run a new system with the adapter. My manual infact
says you can use a 20 pin by aligning it to the right. I wonder what the
other 4 pins supplied? Possibly the PCI-e of which I have none (intergrated
graphics). What are the advantages of a 450w 20pin PSU instead of a 300w 24
pin is I suppose really my question now. My calculations indicate that I
need about 208w based on my current installation. So I think I am goning to
keep with the 300/20 until I install another piece of hardware!

You can buy adapter pieces.. http://www.xpcgear.com/20to24pinatx.html..

Then again, your 300w 24 pin supply would be ok for now, if you only require
208w anyway..

The mobos that I've used have a 4 pin connector somewhere in the middle of
the motherboard. Its for the extra 4 pin connector as part of a power
supply. It carries additional 12V directly to the motherboard.
My understanding is its part of the later PCI specifications. 2.2 or 2.3,
not sure.
