1600w Lepa is a multi rail PSU. Check your 6pin connectors that go to the SP20 and make sure each 6pin pci-e connector is on a separate rail.

I know i am a geek so i am sure as hell know that you can not use 2 rails from 6 because they are only 20 amp
And you can not use any of the second cables and connectors on the same rail on the psu

But i gotta be honest i do not like the lepa psu's, yes they are best priced but to be honest i regret i ever bought it.
The plugs are weak and break off easily and in every way its an obvious cheap build.
If you try to use an 8 pin on the 20 amp rails it often does not even start. ( tried to power 7970 amd non oc'd which has 2 pci-e pin in case you want to oc )

Anyway its besides the point it is connected at the EVGA 1600G2 with its massive 1600 watt 1 rail
After it arrived i was pleased to see the fat cables and insane 9 pci-e connectors

They cost a small fortune but its really rock solid

However if one wants to have a super strong psu for cheap which often does as good as a gold psu, find the antec quattro 1200 (pro) second hand and you have a very good psu.
It even is as good as the platinum corsair 1200 in most cases, both ran with several miners and gpu rigs and give almost exact same readings on the wall.
The funny thing is the quattro is only rated 80+ silver and in my situation beats a lepa gold rated but showed same as 80+ plat in efficiency Cheesy

Maybe i been lucky with these 2 but i like them a lot, very good miner psu's ( the 1200 means i can constant deliver 1200 watt)
I have not been able to findout what these psu's actually maximum power is.

But they have limited pci-e plugs, so you need to hunt down some really nice pci-e splitters on ebay which do not have the scary thin cables
