Hey I have a seasonic 1200i that has worked well since nov 2014 on my 6 cube Titan setup
summer it toggled itself off...so i put 2 cubes with 1 dead die each and reg working full cube on it to save (100 watts)
it did this on me again less then 1 month ago
and it was fine up to this week...now it has 're-lighted 2x time in 3 days"
so my post here on such..in that the 'asic gods' are trying to tell me something i fear (like get another corsair 1200i you cheapskate!)
![Sad](https://bitcointalk.org/Smileys/default/sad.gif)
so my question is I have a 660w corsair (remember knc in 2013 saying they were gonna have 3rd batch and then did not yeah still new lol)
![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)
anyway I COULD make this 6 port unit with 3 cubes (fading corsair 1200i) into a 5 cube unit and move the cube to my other controller using above seasonic 660w
so that my 2 cube titan unit (works fine with 860w seasonic) into a 2 psu unit and 3 cube unit
that is my cheap ass plan (unless folk think it is too dangerous from what they see my psu doing..thus this post to other titan types)
BUT is this a 'sign from the asic gods' that the PSU is going BAD big time and I should just replace it?
(the self test comes up ok go figure)
temp in basement is like 64F so THAT should not be an issue..also have euro 220v tripp lite surge protector on the unit...and the other corsair on same controller
works just 'dandy' ..that one has the controller power as well...so the 'fading 1200i goes and poof' she mines at 1/2 speed ....
(as i sit here looking from work at my 429mh vs my usual 645mh ...gee a whole 2 bucks a day I'm losing after electric! (the horror) with LTC anyway
anyway if worse comes to worse the only problem with my 'cheap ass plan' is even running 2 cubes it 'fades out and off" and it won't be stable ...I will try this
would be slick if I could at least 'see' if this could limp along with 2 cubes only.....save me 309 bucks (or at least alllow me to get a new corsair 1200i and keep in the box
as a spare ...if I go full coward)
if folk on here have more experience with this then myself and say NO DON'T it is a sign of something worse and could fry the titan etc would appreciate the 'heads up"
....but anyway just wondering what folk think
also have the old 7 year parts and labor warranty on this corsair 1200i i psu's is the postage/costs worth looking into to get such refurbished? (309 sale w/ship on newegg as an example
of new corsair 1200i costs incl shipping)...has anyone every 'refurb'd' a psu on such a plan after the 30 day replacement has passed...is it worth it?...
anyway appreciate it ....don't need to turn the 1 titan into a 'doorstop' quite yet
![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)
if the consensus is my PSU is shot as hell and just letting me know before it 'blows up"
(i bet we will see more of these posts...actually like 14 months 24/7 probably is NOT unexpected to replace a PSU on these....but still)
anyway 'expert' advice from others 'maybe' with similar issues (gpu/asic/or other) please reply with advice
thanks
Curious, whats the DCDC temp difference you noticed?
They managed to keep temp below 80F during summer months, but I also added individual heat sinks to the DCDC module (like in Swedish video). Temp would go up to 90 when I was using stock fan.

Did you get a picture of your 'obviously' modified cut down 'heat sink plate' on the above also (or a link)
trying to 'man up' and do the same
on a side note I 'heard' from someone who got an email from kurt at knc (tech) back in the day ..that you put the 'thermal paste' on the 'heatsink' not the chip..just enough to cover it
not sure if legit advice or not (it is a knc tech) but figured I'd pass it along here .....perhaps we can have a debate on the merits of each

anyway my plan is if I ever do such I will simply take the 'heatsink plate' to a local metal shop ..give the guy 10 bucks to cut it 'precisely' and buff it up...lazy that I am

anyway again a picture of your mod would be great!
