PSU Compatibility/Upgrade

LeoPheonix · 21 Nov 2007 at 16:32

I am considering my upgrade and I am concerned about my PSU. I have two PSU's running my system. The Main PSu is an Antec True550P and the second is an Antec True380SP. The motherboard is an Asus P4c800-E which is a socket 478 mobo with a P4 3Ghz HT processor. The second PSU powers my 6 hard drives and 2 DVD's while the main PSU powers everything else.

The question I have is will the connectors on the PSU which attach to the mobo still work on the new Asus Maximus Formula SE?
I am trying to avoid the additional cost of buying a new PSU - although ultimatly i will buy a single quieter PSU.

Thanks in advance.

I was considering the Coolermaster Real Power 1000w Modular Power Supply if i do need to replace.

I would have thought that the True550P on its own would be sufficient for your system but perhaps you've tried it and found it wasn't. Is your PSU ATX2.0 compliant?

You are right, I bought the second PSU when I found the first was not sufficient. (i can't remember if the first was the the 380w or 550w!)

How do I find out if it is ATX2.0 compliant?

It should say on the label but other than that you can check to see if it has a 24pin motherboard connector, PCI-E connectors (six pins in a 2x3 arrangement, normally black) and SATA connectors (small thin flat connectors, again normally black) then it probably is ATX 2.0 compliant.
