Kolink KL-1000M

I have one of the specified PSU driving a 2600K and two GTX1070s used for folding. The CPU is doing nothing much, the gpus are at full load.

Underclocked together by -100 MHz, both cards at full load and the overall machine works fine.

Either card overclocked by +100/600 (core/memory) is fine with the other card not running.

Both overclocked and running and the machine hard reboots.

PSU issue do you think?

Anyone had issues caused by sleeved cable extenders?

They have been known to cause issues before, have you tried without them fitted

Most likely a psu issue because basically it's crap. There is not going to be any quality at all in a pretend 1000w modular psu costing less than £80? The 12v rail has only 840w on it and I doubt very much if it could manage anywhere near that. There is a disclaimer on the label stating that total power should not exceed 850w and couple that with the miserable 2 year warranty even Kolink have no faith in their rubbish psu's. Someone on here took a KL400M apart and it had the cheapest nastiest internal components they could find. There are plenty of threads on the internet with tales of these Kolink psu's being DOA, blowing up at first power on, blowing up/failing after a couple of weeks use. Kolink is best avoided. Buy cheap, buy twice especially when it comes to psu's.

I currently use Phanteks sleeved cable extensions for my 24 pin, 2x 8 pin, 8 pin pci-e and have never had any problems. I have used Bitfenix ones also and never had any problems with those either.

Maybe it's the combination of a crap PSU and extension cables bought from aliexpress. I've removed both the motherboard extension cables and the PCIE extensions and the machine is again seemingly stable with the cards overclocked.

I will look for a better PSU though.

just removed them and the machine is better for sure.

It may not be the cause of your issues but they have caused problems before

Certainly sounds like it
The phanteks ones were pretty reasonable price wise to be honest
All for saving cash

But sometimes it's better not to skimp on some things

I don't really understand why these extension cables are all so long. On a 24-pin you see maybe four inches, on the 8-pin maybe two, on a PCIE cable maybe six. Yet they seem to be around 18 inches.

By the way, computer "folding-stable" with overclocked gpus for 13 hours now. Only change is those extension cables.

Yeah I agree they are too long mate
The 24 pin especially makes cable management at the rear a pita
