Certainly does.  I think many miners are still safe at for a little while.  For some reason the hash rate gets high over the weekend then gets back lower after the weekend.  I don't know why?  If I had miners, I would keep them on 24/7 as long as I could.

well some companies hash on equipment they are supposed to ship you know well we cant ship sat or sun so lets point em at our pool etc

Here's what pisses me off:

Bitmain says the following regarding their S4, "Power line not included. You may look for one line with no less than 16A in your local market."

Well, I've searched the WORLD WIDE WEB for a C14 Power cord and cannot find one rated higher than 15 amps.

WTF?

Pretty sure they made a typo and meant 16Awg. If you're running on 240v you need an 18AWG cord, ND if you're running 120v use a 14AWG cord.

240V/16A plugs are common in other countries. The cable that shipped with my S2 was a 16A 240V 50Hz.

Your S2 will be fine with a 15A cable.

The more I thought about it, 1400 watts [S4 built in PSU] amounts to no more than 11.6666667 AMPS.  So, a 15 AMP should be fine.  I'm still getting a 14 AWG rather than 16 or 18 AWG.

I bought this one:

  Amazon.com: Tripp Lite Heavy Duty Power Cord, 16A,14AWG (NEMA 5-15P to IEC-320-C15) 8-ft.(P019-008): Electronics
  http://www.amazon.com/gp/product/B0091F8GP6/#

It's a replacement for a heavy duty server room style UPS.  When i got it, the packing slip said 16A but the packaging the cord was in said 15A.  Anyway until I received that my S4 ran fine for 2 days with a standard el-cheap-o 10A PC power cord that I had laying around in a box in my closet, so I wouldn't stress about it.

The 15A is nice, though!  So stiff you can hardly bend the thing :-) the A/C cord that came with this PSU is really beefy too:

  Amazon.com: EVGA SuperNOVA 1300G2 ATX12V/EPS12V 1300W 80Plus Gold Power Supply 120-G2-1300-XR
  http://www.amazon.com/gp/product/B00COIZTZM

I bought that to power my S3's -- It is awesome in every detail!  Hands down the best power supply I have ever owned :-)

thanks,

The average over the last 10 blocks (including this one) is 4:40, which is well below the expected time at present.

Good times the last couple days for sure.  This long block may be my fault i upgraded a couple of my S1's and as soon as i plugged them in we hit this 15 hour block.

Were did you get your upgrades? I have 7 S1's on the way from ebay and was thinking about upgrading them.

I have seen the one you purchased on Amazon.  It is a kettle cord.  A C-15 made to fit a C-16 connector.  It is used for higher amperage appliances.  It also has a valley in the C16 connect which does not allow a C-13 cord to plug into it.  However, a C-15 or C1-3 cord can plug into a C-14 connect.  The S4 has a C-14 connect.  I'm just going to purchase Trip-Lite 14 AWG C13 10 feet cord for the S4.  Uses the same gauge wire as the Trip-Lite C-15 8 feet cord you purchased from Amazon.

Thanks for your description.

I ordered them from BITMAIN before they sold out.  They should be making more soon.  Hope they do anyway i got 3 more i wanna upgrade.  Seems they have some pretty cool products coming out soon.

Something else yall need to remember is the length of the cord.  A 10 ft cord will get hotter and pull more amps than a 3 foot cord.  All my miner power cables are 3 ft or less with an iso bar behind them.

Unfortunately, bitmain said (in this thread I think) that the upgrade kits have been discontinued! I'd like them to go back on their word, but seems unlikely.

Actually given the same load attached to a cable, the longer the cable, the more the resistance, the greater the voltage drop across the cable (lost as heat), but the current drops. Since current drops, an infinitely long cable would have all the voltage drop but no current and would be cool.

There isn't that much more resistance in a 10 feet cord versus a 3 foot cord; even if we were talking about mili-amps.  Since we are talking about "amps" and not "mili-amps," the amount of resistance in a 10 feet cord versus a 3 feet cord is irrelevant.  Even if we were talking about mili-amps, the amount of resistance in 10 feet of 14 AWG cable versus 3 feet of 14 AWG cable isn't much difference to amount to anything.

Wire Gauge Resistance per foot

4   .000292
6   .000465
8   .000739
10  .00118
12  .00187
14  .00297
16  .00473
18  .00751
20  .0119
22  .0190
24  .0302
26  .0480
28  .0764

3 Feet of 14 gauge (AWG) [.00297 x 3] = .00891 Ohms

10 Feet of 14 gauge (AWG) [.00297 x 10] = .02970 Ohms

The gauge would be more important than the length in this particular case.  That is my opinion.  This is why I would rather have 14 AWG C-13 Cord rather than 16 AWG (Average Wire Gauge) C-13 Cord.
