Safe in electronics means "well within compliance" which means only a disaster would do any harm which given the probability, one in billions of cases.

So my server PSU woke me up with a loud pop last night. When i got to the rig it smelled burnt. It was one of my DELL 1400w server PSUs which was running at a load of 1000w.

Probably just because of poor refurbished quality but anyway, the breakout board won't light up anymore but none of the cables or the PSU case look burnt. I guess something just popped inside. My question is can this be repaired or do some people buy these kinds of PSUs? Or am i stuck with using this as a paper with or souvenir? What have you guys done with stuff like these?

Any ideas would be appreciated. Thanks.

Well I'm not privy to what's going on in the factory but I also never sign any NDAs so I can tell you there is a mad scramble to get hardware out ASAP and they've been leaning hard on me to try and make sure the first firmware it's being released with works as reliably and solidly as possible. There will definitely be firmware updates in the future but for now things seem to be pretty close. I got involved very late in the piece and I've worked very hard in the last couple of weeks but there are limits to my time and just what I can achieve to get working code out.

One thing I have managed to achieve is to add tuning to the driver. The driver has a 5 stage tuning process to try and set the lowest stable voltage possible for minimal power consumption and then it tunes each chip individually to the highest frequency it will tolerate to try and optimise the hashrate. It also has a PID type fan controller to try and maintain optimal temperature with minimal fanspeed. There are a few emergency things included too in case of fan failure, chain dropouts etc.

I am looking for Bitmain coupons, values of $300, $450, $500.

If you are not looking to buy machines with them, sell them to me!

I will buy at these prices:

• USD300 @ $60
• USD450 @ $120
• USD500 @ $150

Will use trusted escrow services on this forum, for both side's protection.

@Philipma - Thanks for business and it's an honor to host for a btctalk Legend as yourself.

@Eyedol-X - Houston Base

@Hawkfish007 - Thanks for the kind words.  Yes, I wanted them to open up to regular miners so we all can have access to a low cost quality provider.  Previously they only host for larger accounts.  As you know, this is their 3rd warehouse with a 4th opening up so I said why not open it up to the Public.  That's why I took the liberty to help them advertise on BTCTalk.

@DebitMe - Only ASIC hosting for now at this Facility.  GPU hosting may be open for the future but there are higher requirements for GPU hosting as it is also more resource intensive.


They also sell Mining supplies.  I buy most of my stuff thru them and Hawkfish007 / Finksy.

I'd say what is my 'thumb rule' with almost all asics, below 90C to avoid miner failure and below 80C for longer life time.

Still doing some speed tweaks to mine. Trying to find the Frequency / Power sweat spot.
I just found out that 3 that came together off the same power supply can vary a lot.
As in 4% less power at the same frequency.
Going to leave each one on the test bench for a few days to see if it maintains that. 30 Watts is not a lot but it all counts.

my 12c kWh self here...hates you...(that in that where you live is friggin WARM..unlike Minnesota!)

I got them almost free after rebate like 5-10 years ago. was actually the first psu's i ever bought.

I know that. I insist, I just want to understand why DT1 members added those users
Do you find any explanation why nonnakip was added? You seem neutral, of course I'll really consider your possible explanation

I know that too. I'm still digging deeper and help is much appreciated. Discarding everything is not helping, digging with me is

I'm open to be corrected and I'll admit if I'm wrong. But I'm not open to be discarded without arguments
philipma1957 is suspicious of me and that's perfectly fine. But he's really checked his list. Of course it's fine he keeps the users he considers must stay after his checking
I no longer believe he is abusing the trust system

OgNasty has just denied everything, even straightforward cases like nonnakip, and hasn't given any explanations about that at all

Tomatocage hasn't reacted yet. Let's see what happens


I appreciate you re-checked them

Feedback from other users would be helpful here then. It seems you're very open to listening to them

Do check what happened by your deletions. Do verify what would happen if you remove more users. Do keep your exclusions if you've checked them and don't trust the feedback they've left. Do leave negative trust to those whose trust stopped being red because of your exclusions (if any). Do not trust me. I'm happy you did check your trust list, whatever the result

I don't see how I could prove I don't have a hidden agenda, even if I disclose who I am

I really appreciate you didn't take this as an attack to you (even though you're suspicious) and instead were open to check your list

Again. You should check at my arguments and decide for yourself. It shouldn't matter who I am

Here are some comments about some of the users listed by you:

CrazyGuy: hasn't left any trust in a long time
kano: no conflict of interests as he hasn't left trust to you, but has left only one single trust and it was 5 years ago. I don't see why you consider he should be on DT2
Cablez: hasn't left any trust in a long time
davecoin: no negative trust left at all (no scammers tagged)
buysolar: only 3 positive trust left, 2 of them to you. The last left feedback was 3 years ago
not.you: not active during the last year but has tagged some scammers
btcxcg: Only 5 positive trust left, including yourself. No negatives sent. Last feedback was 4 years ago
generalt: No negative trust sent. Last (positive) feedback sent was one year ago
Mikestang: Last feedback was sent 2 years ago, but he did tag 1 scammer at least
vg54dett: Only 6 positive trust left, including yourself. No negatives sent at all
AriesIV10: Positive trust only to 2 users, including yourself, only one negative sent

I'd appreciate if you can check again kano, buysolar, btcxcg, vg54dett and AriesIV10
(other users, post your comments about these members. I don't want philipma1957 or others to believe I have personal issues against any of them)
And you may consider adding users who leave much more feedback after you verify they're not abusing as I didn't find any really active user in your list


I'll check OgNasty's and Tomatocage's lists later

Bro Phil, what do you think about Vegas and some 550's/1050s jumping on eth? aren't they enough to pull up such diff?
