x38g reports
Pepi:
It looks like fuse problem in PSU, not PSU itself :) But since you will not open PSU since you loose guarantee you will never know :)
Always you can look at bright side of life :) What if all other components dies, but not PSU. That will me far more damage.
P.S little advice.
Don't mess with 450W PSU of lower quality and GTX 260. It is power hungry beast, and or PSU or GPU will be damaged is there is no sufficient power.
Yesterday I finally got more then 120 WU, so can start crunch normally at least 24 hours :)

LoL, I agree, but I've been trying to kill this GTX 260 & PSU (turns out now I look it's a thermaltake 470W, so not completely crap, but not enough for the 260) for a long time so that I can justify getting a newer one for the machine it was in ;D...

Besides, I have ~2400 tasks on this machine, if something dies trying to whittle that down I'll call it a noble sacrifice & give them a decent burial. I'll take your adice to heart & run it underclocked though ;)
The stupid part is that I have the skills & tools to fix the 750W unit, but, as you say, don't want to open it *sigh*
Pepi:
You try to kill GTX 260?
It is peace of cake: use 12V , put one cable ( + or -) it is irrelevant on any gold contact of PCI express, and with other make contact with all other gold contacts.
That will kill it immediately :)
That is how I kill some computer parts.
PSU is hard to kill, it shutdown itself with any voltage irregularities :)
And for all of those WU, make backup of both BOINC directory regularly :) And put it on some other hard disc :)

I hear you on that! If mine went belly up, I'd have a hard time not opening the case, and digging into it. I'm really sorry your supply died like that. You are right in that these supplies are the best you have ever owned. The 1200 Watt version I have is better than anything I have ever seen.
As far as x39e, or any of the other builds I have run live, I haven't experienced a single problem. These 480's are crunching away like jet engines, and have held up perfectly, even at an extreme overclock. 871 MHz vs 700 Mhz stock.

AS you know I killed the second 1000W PSU with my V8-Xeon. Now in the summer it is not possible to run the machine with 3 Aircooled 470/570, we had some days ago alredy 36 grd celsius outside, and the house where I live has no climatisation. Still a watercooled system and perhaps a 1200W PSU is able running the whole year continuous.
I must wait till late autumn to repair the machine. :'(
