What a palaver - power supply recommendation

[Echo toxin]

So I came to do a couple of builds last night and encountered a hiccup or two which hadn't even crossed my mind.

Got an Antec Trueblue 480W power supply from about 3 years ago which is 20-pin and hence wouldn't fit the new 24-pin Gigabyte DS3 mobo. Ordered a new case with a 24-pin power supply which wouldn't fit the old 20-pin motherboard I put in it.

Thought about swapping them round but the new power supply doesn't have a PCI-Express power connection.

So anyway, I need a recommendation. How many watts should I go for on the Gigabyte DS3 with two optical drives, a PCI-Express X850XT and three SATA hard disks? Would an Enermax Liberty 400W be enough or do I need to go to 500W?

Cheers!

Liberty 400 should be more than enough, you can get adapters for PSUs lacking a PCI-E 6 pin btw.

Can't you just swap the psus over?

You can get a molex to pci-e power adaptor for the new psu. Thats assuming the new psu is any good. Take a look here.

In the end, I gave him my Enermax NoiseTaker and bought myself a new Enermax Liberty. Hope it fits in my Lian-Li V1000 properly. I can see that all going wrong now.
