Pictures of your mining rigs!

I believe everyone has once again reinforced why I don't use the server PSUs, although they are really the best bang for the buck. Not worth the worry in my unmanned site.

Huh? The wire/heat/potential fire issues we were having were with an ATX PSU. Our modified server PSUs have never given us any issues. They're rock solid!

I love mine that work - but ive spent way too much time testing some that dont, particularly the dps-800gb supplies. 2 kicked out on me, 3 fail to work with the 31+34 pin mod, and the 3 that work still are great powerhouses

Love the modified server PSU, I've considered using them, but concerned over a potential increase in fire hazard. I know those dells have pre-configured kits, but didn't know if it can cause potential issues as I read a couple people saying they had hot wires to the touch.

If wires are hot, they are probably not thick enough. Hmm, third hit says 18Gauge is good for 16 amps.. would not want to run more than 5 though that. This pages seems to agree, but qualifies that with a maximum length.

I would put the practical limits (based on experience) around:

18AWG (Quality product such as PSU cables) - 10A maximum, 8A is safe
18AWG (chinese mlex adapters and other flimsy wire) - 6A maximum, 5A is safe

16AWG - 15A max, 12A is safe
14AWG - 22A max, 17A is safe

generally my antminers use the 14AWG wire in order ot reduce clutter and simplify things. The wires get slightly warm when using only 2 pairs of wire for an S1, but probably only 30C or so which is quite safe

C

Return On Investment. The time it takes to earn back the money you have put in.
If your miner costs 1000 usd, and you earn 200 usd a month the ROI is 5 months.

Actually, you're describing "Break Even".

There's always a Return on Investment.  But it can either be Positive Return (Profit), Negative Return (Loss), or Break Even (make back what you invested).

That said, I think you also missed something else here... I believe Lightfoot was being sarcastic.

I stand corrected, and apparently my sarcasm detector failed miserably

I use a pair of 16awg on the ants (2 + and 2 -), no problems at all with temperature. Ants overclocked to 375.

just reorganinzed 150 Ghash/sec of cobbled together over time gear into a nice little woodworking project.

3 NFY NF1
1 BPMC BF1
2 KLN K16
2 OSM DIY0
1 Mboard w/ (presently) 3 cards; with 4 planned additional hcard minis each with 8 asics (2 rev.1 ßitfury, 2 rev.2 ßitfury)

after all additions ill be sitting at ~240Ghash/sec
