Did this one plug run 2 cubes?  AWG16 are rated to handle 16A if you have top shelf 90C rated wires.  4 cable pairs at 12V is a pretty simple power calculation:  4 x 12V x 16A = 768W

Each cube takes 350W.  2 of these should be lower than the 768W max of those power lines, but you probably didn't take into consideration the plug is rated at 13A.  This is why the melting started near the plug, not it any wire kink.  Each cube should take a single plug directly from the power supply...with its own plug...this means no sharing.  3 cable pairs x 12V x 13A = 468W.  More than enough to handle the 350W required by the cube.

2 pcie plugs would have been a seriously cheap solution.  I think the real solution is to remove the crappy plug and hardwire 2x 8AWG lines to bus bars.   

Lesson learned: KnC cut corners, but buyer beware.  Do the math and save your ass.

Bought 1 Titan.  FW 1.04 and 1.03 had same result.  3 cubes work flawlessly at ~75Mh/s....1 cube had a single core producing a paltry 7Mh/s, other cores in this cube are dead.  RMA'd the bad cube.  Currenlty mining ~225MH/s at litecoinpool.org, 115%pps because they keep the doge (which is fine with me).   Stupid alt coins switch too fast for the titan anyway.  Even 2.5 minute blocks is too fast for titan with their 4 second flush.  That's a ceiling of 97.3% efficiency!  What a joke knc.

Time to pile on ---->  http://kncclassaction.com/

I received one defective cube as well.  3 of 4 DC/DC down.  The cube hashes at about 7Mh/s in bfgminer.  The other three cubes are working flawlessly around 75Mh/s each.

It seems as if this problem is widespread.  Do you think KnC has manufactured numerous cubes and shipped 3 winners and 1 loser to each of their customers?

Safely shutdown Titan by killing power to the controller board first, then power cycling the remaining power supplies directly connected to the cubes.  You can also run command "sudo shutdown now" to shutdown softly or "sudo shutdown -r now" to reboot softly.  All needs to be done at bash command prompt from ssh pi@.

Replacing the class 4 SD card with a class 10 gives better read/write capabilities to the linux platform.   I'm still having a problem with reboots though.  The miner will run for a while, heat up the DC/DC on the boards and then blank any submissions, yet bfgminer stays open for a few minutes until the counters reset and start mining again.  Lots of delays between submissions.  The first 8 hours of mining has been sporadic at best.

Throttling all hot DC/DC cores back to 275MHz to see if the hardware is just stressed.  In 1/3 of a day, I have only roi'd 1 ltc.    More details to come.

Stoaked.

Don't get too hyped up...it backed off to 300-325Mh/s.  Firmware 1.03 FTW!

Looks like cheap scrypt coins don't work because the flush occurs so fast.  The reset on the getwork is a significant delay that affects only poolside results.  Say good-bye to multipool coin jumping!

Disappointed to see 1545VA at the wall.  Good thing this is a 20A socket!  Took 3 hours to setup, which included killing the first build with bad firmware update.

I highly recommend ditching the class 4 micro SD and purchasing a class 10 4GB to get more stability.

Currently mining at www.wemineltc.com (0.5% donation) with dogecoin aux-pow.  Seeing 330MH/s+ poolside.

I second the douche nozzle remark.

That being said...My titan is on truck for delivery today in the United States.  Order # 1990x, paid March 19th @ 16:46 knc time.

For everyone complaining about the pool side speed being too slow....try solo mining to a local wallet.  Setup RPC files with your worker credentials and point the miner to the local ip/port.  You will likely see the full potential of the Titan, hopefully 300MH/s, when removing vardiff stratum latentcy.  Local mine first too see your capabilities, then move to a decent pool like wemineltc.com or litecoinpool.org that can handle the extreme vardiff requirements of the Titan.

When your miner operates faster than the pools' databases, you will see defeated pool rates.

Order #1990x  Paid March 19th @ 16:43 knc time.  Switched to shipped this morning when I woke.  A few hours later, received a Quantum update email from UPS directly detailing a Monday delivery.

I eager to work on my DIY kit.  :|

Likely that reaching out will not accomplish anything.  I was thinking about taking a page out of the ftc playbook with bfl and file an injunction with their business licensing arm in Sweden.   Claim that the business that sells products that have a shelf life were delivered after their profitability expired.   If KnC wants to do business in the future and sell the soon to be released "phobos", or something equally as dumb, they will have to address the duress claim.  You can't order foundry business without a fiat account...a business license is required for a fiat account.

Either way, I have a lawyer looking into the process for US-Sweden process.  PM me if you want to be on the hotlist of a class-action-esque suit.

March 19th, 8 hours after the pre-sale press release.  16:49 knc time.
They haven't even made it through the first day of orders.  I'm somewhat happy they didn't meet their Q3 promise...now I get to mine and be a part of the class-action suit against them for breach of contract.

Queue update: order number 1990x switched to "in progress" when I woke this morning.  Hopefully ships in next 24hr.

Order 1990x hasn't budged from "paid" status.  I made this order 8 hours after the pre-order press release on March 19th.  Looks like Q4 is showing up with knc dropping the ball on that Q2/Q3 promise.

wemineltc.com has high availability pools with high VARDIFF that auto adjusts....should be able to handle the whole worker at 300MHz.  Merged mining with dogecoin too. 0.5% donations is recommended.

What was your order number with KnC?  When did you order/pay on March 19th,2014?

www.blackcoinpool.com  Reverse the value depreciation by selling useless minable coins and buying unminables that appreciate with scarcity.

As it was with the Jupiter, let the heat build up in the case.  They should be stable up through 50C.  

Wafflepool creates bad vardiff issues with hardcore scrypt miners.  Try to eliminate any rejects, start solo-mining to a local wallet...then post results.   Vardiff doesn't matter if the solo-miner client is on a Gigabit LAN, or even a 100MB LAN.   Start solo, then go pool.  Perhaps mine an alt with low diff if you want to get paid out for test time....something like potcoin or feathercoin has good market volume.  Doge and ltc are too difficult to test-solo-mine.

Edit:
Lol  @ Wafflecoin

They top out at 128MH for VARDIFF...they even make you set it at login for the worker.  Think you might need to move pools bro.

I ordered a Titan on day one...about 8 hours after the press release dropped.  Order number 1990X (X to provide anonymity).  For those who have received their titan orders....what was your order number?

It seems as if KnC built the miners sold to customers promised Q2/Q3 (which actually means Q3) delivery, then delivered within the last few days of Q3 to meet their previous pre-sales promise, but they are dragging their feet!!!  They must be mining Scrypt, something fierce.  Seriously, when is my Titan going to be shipped?
