a lot if you spend enough. But getting that money back is hard and costly
Ah 18,000kH/s very nice!
I hope it goes well with the fuse box
Just wondering how easy is it to change for cash? And do wallets like blockchain support litecoin?
I might try a small rig as it's quite tempting to invest some savings as profit seems higher

Not more cost!
Don't rule out the effectiveness of forced air cooling. If you could get enough air moving (box fans probably wouldn't do it) then even in the summer you should be ok. This comes from experience of systems running in 40ºC ambient and kicking out 20+kw of heat.
Well, slight update.
One of my 1300W PSU's trips out when I fire up the 4th 280X. The other 4 are working perfectly fine each with 5 identical cards running in identical machines.
Electrician has been today to fit a new garage unit with 32A on each fuse. 3 rigs on each now.

, are you going to RMA the power supply?. The psu sounds faulty not holding the 4th gpu. I had to RMA my MSI 280x as it started squeeling and the fan oil was leaking out the fans

running 7kw on 1 single 32A ring 24/7 is asking for trouble. If he's telling you its safe then get a new sparky tbh.
Bring another ring down there and split the load as evenly as you can

Well 7000W would the worst case scenario.
7000/240 = under 30A. He should be ok?

How is it worse case? He added up his usage and it came to 7kw.. His miners are on 24/7,..
UK is 230/240v mix, 7000/230 - 30.4A
Though the main issue here is also heat, I imagine his seller is HOT (I remember him saying its uncomfortably hot), When the ambient room temp rises, The load a cable can carry drops. IE;
10M length of 2,5MM T&E, Clipped to wall @ 30c ambient = Max 23A
10M length of 2,5MM T&E, Clipped to wall @ 45c ambient = Max 18.1A
Voltage drop calc

Worst case as in the maximum amount of power he is drawing from his PSU per rig.
Yes if you want to calculate a truly worst case then divide by 230 sure.
One thing Im vague about is the core which is being used. If its anything above 2.5mm he should be ok. But 2.5mm is rated at around 20A (depending on temperature) so defiinite no no.
But if his sparky said 32A is fine, he wouldnt fit a 32A breaker surely on a 20amp max ring surely.
Fair enough. But as said above, if the sparky ascertained the ring is rated at 32A, he then should be ok, albeit at the topc end of the 32A.
Ideally he wants to move to a 6 core. Thats what I maybe doing soon.

Considering both legs of the ringmain it could well be 2.5mm with a 32A, Each leg carries a min of ~20A IIRC
But who knows if the sparky has properly de-rated it on the basis of how hot the room is going to be (Miners was probably off when he came so assumed cold room..) and the consistency of the load too needs taking into account.

Could be. But if it was me, I would definitely follow StonedPenguins advice (and my own!) to double confirm the above points as well.
Got another sparky coming over tonight, always good to get a second opinion (although the first guy yesterday seemed quite clued up).

A 2.5mm RING (as the photos show) is fine at 32A. A 2.5mm RADIAL, would not be. The temperatures could become an issue, but without knowing how hot it is actually getting, conjecture is pretty pointless!
