I was wondering what power supply i should use for my system. Here's What i have:

Soyo SY-P4S-645DX DRAGON Ultra mother board
P4 2.4Ghz CPU
1Gb DDR333 Ram
2 Seagate 20GB Baracuda ATA4 7200 rpm hard drives
1 Seagate 80GB Baracuda ATA4 7200 rpm hard drive
1 Western Digital 120GB 7200 rpm hard drive
1 Maxtor 30GB 5400 rpm hard drive

You've got to have some cooling fans too? With all those hardrives, the True Power 550 may be the safest option for you, or maybe the 480, personally I wouldn't take any chances and go with the 550.

I agree.

Get the most expensive one you can find.

My suggestion would be a quality power supply that supplies plenty of power to the 12V rail, since high performance harddrives do pull about 2 amps a piece off of this rail. Enermax power supplies by far supply the most 12V power over other power supplies....My suggestion is to go with an Enermax AX465-VE (466 watts))....here are the power supply specifications:

3.3V 38A
+5V 44A
+12V 33A

compared to the antec true power 550
3.3V 32A
+5V 40A
+12V 24A

Both of these are great power supplies but I personally opt for the Enermax :smile:

I would also recommend a Enermax AX465-VE.

A little sidenote: I don't know if you plan to use the Seagate Barracuda IV drives in RAID 0 but I don't recommend it... their performance under RAID 0 is very poor, you will need to contact Seagate for special RAID 0 versions of those HDs if you want to use them in RAID 0 at maximum performance and already bought them.

Anyway I recommend atleast a 450W PSU with high 5V and 12V amperage.

My dual-PSU PC is so powerfull that the neighbourhood dimms when I turn it on :eek:

Your main concern should be the 12V rail. If you consider each hdd requiring 2A on the 12V line plus that cpu is rated at 8.5A at 12V plus the dvd and CDRW drives; Make sure you PS has a 12V rating of at least 24A. The overall wattage rating should probably be around 450W.
