I think bitcoin mining is going to quickly separate the men from the boys when it comes to PSU brands.

We are going to see a lot of blown up power supplies! 

Thermaltake wasn't banking (pun intended) on bitcoin taking off.

If the internet goes down anyway, what is the point of keeping the system on battery backup?

Just have a reboot cycle when the power comes back on.

For voltage regulation, the Tripp Lite LC1200 can provide sag and surge protection for up to 1200 watts. It also has $25,000 connected equipment insurance. I've done some research, and it seems this LC1200 regulates power better than some UPS units. Given that 1000+ watt UPS units are very expensive, it is likely that many people will buy the cheapest one they can find, and unwittingly achieve worse line conditioning than the LC1200.

I will get two, I think. For $120 each, seems to be the most bang for the buck.

There's also an 1800 watt unit, the LC1800 but its nearly 200$.

I can't get this card to run consistently. I have generated 0.005 coins in a a few days with deepbit, but its constantly telling me hardware verification has failed with latest GUIminer. ATI Stream 2.1. Win7 x64.

It doesn't matter if i use stock speeds, overclocked, underclocked, underclocked memory, vectors/no vectors, -w option etc.

Am getting 60-70 mhash/s. Fanspeed=locked at 100%. Temp: 71c.

My system passes prime95 with EC for 12 hours.
