Am about to replace the PSU in my Dell Inspiron desktop 545 and have ordered an Antec PSU, but while waiting checked inside the CPU and found that the original Dell PSU had power connectors that aren't normal. The original PSU connectors do not have the normal "round" female connections ... They're flat connections.

Based on this (and some of the forum entries) suspect the motherboard connector will not be the same either.

I've searched the forum entries but am confused by multiple suggestions.

Does the PSU connector inconsistency mean that I should order of PSU from Dell?

(Several years ago – on a different Dell CPU – I added a second hard drive and the power connectors worked fine – – but the HDD and DVR units currently have different power connections.)

I think you are talking about the SATA Power connectors as opposed to the old Molex ones used for the older IDE. Without knowing the exact model of the PSU it's hard to say what it will come with but if you need to you can add adapters:

This is just an example and not a recommendation of a source. Antec is a high end brand so I would expect it to have SATA Power connectors.

The motherboard connection is usually the same. Most power supplies come with a 20/24 pin connector which will fit most standard boards. If you only need 20 pins then you can disconnect the 4 pin piece from one end and just let it hang.

PS I think the 545S does have a funny wiring harness but it appears like the 545 is a normal one.

You can use molex adapters,and most newer PSU's have the flat black molex..

You can do a bit of shopping around on Amazon,Newegg,Tiger Direct to find these adapters..

Thank y'all for the responses.

I replaced the PSU several days ago and have been waiting to update this. My PC is working fine now.

As many have pointed out, the connectors are SATA – my previous PCs had IDE devices and I didn't realize that the new one had SATA.

Anyway, this issue is resolved.

Glad you got it fixed...
