Is it enough?

[Tigerblade]

Done a search and not found anything that answers my question, so any help appreciated guys.

I have a CoolerMaster Hiper 420W PSU and this is powering the rig in my sig at the mo, along with a 40Gb + 120Gb Sata HDD's.

Would it be possible to add another GTX and be comfortable? IF I did put one in and there wasn't enough power would it fuck anything up or just turn the pc off?

I know I sound totally n00bish but just need a straight answer, otherwise its a CoolerMaster 550w

Cheers in advance

If you have to ask...you obviously need this:

But, as said above, you need a bit more. I'd go no less than a quality 500W for SLI.

Picking a Antec TruepowerII TPII-550 550W in an hour....need this other card in now!
