Hello,

Hoping you guys can help, I’ve been building mining computers for the past few weeks and have 3 rigs consisting of of 12x Gtx 1070’s running smoothly. All of them have 2x Kolink Continuum 1500W PSU’s.

I recently ordered another 4 and all of them have died. Most of them didn't last an hour, one survived for a day. They all died while idle on Windows, half with 2 cards plugged in so I’m pretty sure it’s not overloaded.

I thought It might be the motherboard but it looks okay and the case is made of wood with only the metal screws and rubber risers touching the motherboard.

All their manufacturing numbers are next to each other so I’m thinking I somehow got a bad batch? My friend who also bought 2 at the same time had the same issues and his are dead, they were also in the same batch as mine.

It seems like too big of coincidence which makes me think there’s an issue somewhere but I’ve now replaced the PSU’s with a Silverstone and have no issues. :confused::confused:
 
No it's because Kolink with 95% of their models are poor, you are lucky that nothing worse happened. They have one or two models that are half decent other than that it's best to avoid.

sorry are you running 36 gtx 1070 off 2 x kolink 1500 psu? or am i reading what you wrote incorrectly?

I would stay away from Kolink stuff, the reviews are not exactly great. Stick with the normal brands like EVGA, Seasonic, superflower, ANTEC, Corsair, ect. I would also try not run the power supply close to the stated value, ie 1500w. Allow for some headroom.
 
I wouldn't call a score of 8.3/10 good, more mediocre. I wouldn't even look at a unit scoring less than 9/10 with all the choice of quality units available these days. Saying that, it's all too much of a coincidence to be anything but a bad batch. Enhance are not the best oem but they are far from being the worst. Only a 5 year warranty is pretty poor for a Platinum psu that costs £290 as well although the more expensive Superflowers are just as bad for warranty length.
 
Spoke too soon, broke 2 of the Silverstones earlier today. I'm thinking maybe I'm overloading the actual plug socket - I've got 6PSU's plugged into extensions that go back to the socket.

Going to speak to someone who knows about electricity and find out.

You shouldn't pull anymore than 2500w from a single socket, if you do you're in trouble. (This includes a maximum of 2500w on a extension too)
 
If the electrics on your house are set up correctly you'll just trip a braker or blow a fuse, you won't damage equipment.

My clothes iron is 3200w.

When looking at 1000+ psu I'd be looking at only using Seasonic.

Actually for PSUs over 1000 W Seasonic are a little behind the absolute best IMO, they have only recently been adding them to their range.

No a fuse or braker will only trip on a short or a very high overload. They aren't meant to be protection for foolishness.
Chances are it's on a 32 A ring. This is rated to 7780 W, but would only trip on a higher load or instant short.

Even an extension at 13 A fuse may not blow until it hits 20-25 A.

Overloading like that could cause problems with the supply so it's very possible to be the cause of the dead PSUs. And a potential fire risk as the cables could be overloaded.

My advise would be, only use a good quality extension leads with basic surge protection, limit it to 2 PSUs per extension lead and under 2500 W. And no more than 6000 W on one 32 A ring.
 
I have used a couple as there was no alternative and had to get the jobs out. I am apprehensive but they were bought by purchasing after recommendation from OCUK. Will see how long they last.

IIRC they are the same product as the Silverstone Strider and they have worked well for us in the past.

That's not what I wanted to hear seeing as I've just replaced mine with a Kolink
