Is 480 Watt enough?

Hi guys!!
I'm going to build a new rig, and I need to know whether my old PSU is going to power it..
the specs are:
Sapphire Pure Crossfire 3200 MOBO
Sapphire X1950XT
AMD Athlon 3800+ X2 s939 (or maybe a 3700+ San Diego if I'll get one for free)
1 or 2 gigs of DDR 400 (Kingstone, if it matters)
Umm... 2 HDDs (SATA that is), 2 CD-ROMs, 6 fans (2 LED and 4 regular) and that blue light thingie...

Now, I have a 480W PSU, with a sticker on it that says:

+3.3V +5V +12V -5V -12V +5YSB
12A 30A 19A 0.5A 0.8A 2A

480W

Will it power my new rig?

 

12v-->19A Answer NO

Good Luck

 

What? confused

 

Truth is that 19 Amps in the 12V scale are hardly enough. Of course we're talking about only one X1950XT, I'm saying this cuz the mo/bo is crossfire ready. What brand and age is the PSU? Give it a go if you want but it would be risky.

edit:

That's what the label says. The psu can provide up to 19 Amp in the 12 Volt cable(s).

 

The PSU is about a year old.. Unknown brand..
+ I need to get converters for the PCI-E 6 pin power and 8 pin for the MOBO.
Or should I just get a new PSU?

 

unknown brand, converters... forget it dude. Buy a nice Tagan and "happy gaming".
