Hmmm I have this strange problem...

Bought an Antec SLK2600AMG case in which I put an older CUV4X...
sometimes the motherboard LED lights does not light up! When it does,
the PC starts to boot, but after a few seconds, I loose the image
(video dies), lose all power on CD-ROM drive doors, but the power LED
(on front panel) stays on... I can even push the ATX power switch
button and after 4 seconds, everything shuts down...

Weird issue eh? Anything I should know with new power supplies? Must
they charge for a while before you can hook them up to the mobo?

Thanks.

No, but you ought to try booting with just the cpu+hs/fan, RAM, and
videocard installed. Leave all the drive off and see if it will stay
up. Then try just a single hdd and the floppy. It might be an issue
where you have too many devices drawing current at boot. You might
need to select a delay for the hdds in the BIOS.
