Yes I used the same fan, on your recommendation. What PSU did you get?

[beanhead]

Capacitors have the score marks in the top for a reason, to allow them to blow when shit goes wrong.

Cheap components, cheap capacitors will mean the stress that those components can take is less. That's why your psu is fubar.

Buy a new one and get a decent one.

BTW A2 will take 100 days at 0.002 btc per MH per day to ROI, calculated at an average of 88MH/s. That's not including power costs. These units will never ROI at 10k each if you buy one now. GAW and KNC will have their bad boy units out at the end of September I reckon, even they will struggle to ROI because of all the 80-90MH units being bought currently.

But don't listen to me, I'm just a cynical bastard after pre-ordering a KNC titan and paying 12k after Vat and now KNC have dropped batch 2 by 3k! And will be shipping those just 1month after batch 1, and let's not mention that batch 1 is 250-300MH and batch 2 is 400MH with no hardware change apparently!

Only one winner in mining hardware these days, the hardware manufacturers....

I ordered two Meanwell PSU's they are not very cheap, but they fit in the same spot as the current one.

They claim 88% efficiency for the 12V version.

There is some truth in this, i know. But I first have to see whether KnC and GAW will come with a 500Mh/s machine which consumes low power.

GAW doesn't even make miners, it is only a reseller. That guy Josh has a lot of blah blah but is a mere amateur with respect to mining.

[james42]

My A2's won't take 100 days to ROI, but even if they do, it'll all be profit after that.

I've got a 24V Meanwell running one of my constant current LED circuits at home, been rock solid for the three years it's been running. Have to see if I can get hold of one

They are being sold everywhere, so that should be no problem.
The reseller over here has them in stock, on the Meanwell site it seems to take longer.

[beanhead]

I must admit I only heard of GAW a few days before their 500MH/s miner announcement. I can't vouch for them in any way. KNC are pretty trusted, which is why I made the order with them.

Just disappointed with their tactics. I don't think a month is enough for the drop in price and increase in MH to allow their early adopters to ROI, apparently the increase in MH is purely firmware, so I'm hoping they will release batch 1 at 400MH and give those that pre-ordered and gave them the money to fab the chips a chance to ROI. Wishful thinking me thinks.

Probably the first and very last time I will pre-order if I'm honest.

I'd love to know what you're mining and your calculations.

[JoostB]

I'll never pre-order, too much uncertainty.
Most of the time they deliver months too late or the equipment uses much more power than promised.
KnC also has a bad track record lately, when you read the KnC-Miner thread on bitcointalk you won't be happy.

A bunch of stuff really, some days good, some days not so good. I did very well with Razor, got in very early on that. Otherwise I just look for steady coins that have a good daily range of values, low difficulty, good block reward, and where there is not enough interest in the mining the coin. That way you get most of it and can pull in on average $40-$50 a day. That'll give me a 90ish day ROI. With a bit of careful mining and choosing when you sell the coins though, you can get it much higher. And don't forget to keep an eye on the rental markets, for example when Razors difficulty went through the roof - you could get more renting your rig than from mining the coin.

It's definitely not a mine and forget operation though, need careful planning, research and execution. And stay away from multipools.

And keep an eye on the ANN board here

Yep, my prospects were looking good... untill one blew after only a week. Still waiting....

Estimated delivery date for my new A2Mini is now the 25th of june, when true that will be a lot quicker than last time.

[james42]

I was just relieved when the Interlink website said "We have your parcel". If my usual guy brings it, it'll be here at 9am tomorrow

[minereu.com]

All A2MINI has been dispatched today as we planed

[TCM]

Any progress on getting those shipping costs back from order #2000?

[chipxtreme]

I can vouch for that as when I was picking up my A2BOX DPD pulled and and they loaded a shit load of boxes going in the van. Going to be a lot of happy miners

[nwfella]

Good looking site you have here.  I noticed you doing some sort of affiliate program...guess I'll have to register to get more details.  Seems to be a pretty popular way to try and bring in more potential business.

[james42]

Well my Interlink man is sitting outside my house in his van, smoking a cigarette and drinking his coffee before he gets my parcel out :-)

The picture completes.

It's a working mentality going from IT to the delivery monkeys it seems.
