Would a CoolerMaster LGA775 ExtremePower 430W support 2xATI MSI 3870 in crossfire and amd 5000+ on 3.4GHz+ 2-3 pc case fans?

Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
Question

- Start date
I had a 430w PSU running my server with a Q6600, 4gb DDR2-800, 3 500gb drives in RAID5, 1 500gb removable, 1-92mm and 1-120mm case fans, and a lower end video card. It ran that way 24x7 for 1.5 years before it died last week. I replaced it with a 500w spare I had in the closet.

I think a Corsair 520/550W is about as low as you would want to go & a Corsair 650W would probably be best.
Good Gaming,

As everyone else has said: No. At least, not for long anyway. Hell I don't even think that PSU can power your rig well with only one of those 3870 cards.
Even with a quality 450W PSU that's a bit too close for comfort. You should have a PSU with at least 40A on the combined +12V rail for that kind of setup. Good minimum PSU choices:
- Corsair 520HX 520W PSU (40A on the +12V rail)
- Corsair 550VX 550W PSU (41A on the +12V rail)
- BFG MX-550 550W PSU (41A on the +12V rail)
- BFG LS-550 550W PSU (41A on the +12V rail)
