Power Supply Worries

I have just bought a 2nd UAD-1

so I now have:

P4 2.4GHz
2 GB ram
2x 200GB seagate drives
RME Multiface (PCI card)
Firewire card - not used
graphics card - basic raduim dual
1x Powercore
2x UAD-1

can I run all this off the installed 300W power supply OR do I have to upgrade to a 500w job. I ran OK with above and only 1xUAD but I'm worried the 2nd UAD might push things over the edge?

I'd rather not upgrade coz it's a hassle but I don't want a unstable PC will I be OK??

Thanks

I think it'll work - I used to have a similar setup until I upgraded, too. Not sure if I had a 300W or 350W, though, but I had 3 HDD's.

Cool - thanks Akis

I think I'll install the card and see if I have any issues, anyways sounds like it won't blow up - I hope!

The UAD-1 cards take a max of 14 watts.

300W is a little light. I'd recommend that you look up the max/nominal power requirements for each of the items you've listed. It should be easy to find that in the tech reference manuals. If you had a 350W you maybe able to wing it, but I think you're close.

The other thing to note is that it's better to have some margin, say 20 to 50 watts spare so the PS isn't working to hard, it will give you more life and run cooler.
