That's a bad PSU you purchased. From what I see I can only find that name on Ebay / some forums where the replies say to run away.
One of the good bad PSU signs is the way it has a fake SLI logo on a very cheap looking blog that was generated by an auto-translator yet cross-referencing it with nVidia shows there are no PSUs under that brand name with actual SLI certification.

Just a heads up for this one. First, after researching I found no manufacturer information, so whoever manufactured these obviously did so using the name Kentek that belongs to a Laser parts company who does not manufacture power supplies, I called Kentek and was told I'm not the first to call or complain of the same issue. I purchased one on Ebay for my own computer an to write a review while I have yet to hear from the seller who has plenty more to sell. I suspect possible trademark and other legal issues besides the fact that motherboards of 600 watt or higher require the eight pin CPU connector, rarely six pin and never four pin that is just not right any way you look at it. Obviously either customs or some federal agency needs to investigate considering I would personally never attempt to use an adapter or modify the connections as there can be very serious complications or destroy one's motherboard. Too many people are trying to save money by building or repairing their own systems for such very inferior parts to be sold in such ways with obviously no oversight or at least this should be investigated considering there is talk or reviews stating systems are actually catching fire, exploding or destroying motherboards. I'm sending mine back to the seller on Ebay after writing him about the problem he has yet to answer my messages and it's becoming more and more obvious the seller was quit aware of this problem before selling such an inferior or possibly even illegal unlicensed product considering trade laws etc etc. I strongly suggest considering much further research of this product before purchasing. I'm also college schooled, Dell certified tech, many college courses in computer science, programming and have been building my own and other's systems for a few decades so i so know a little about computers though I don't claim to be a master, and I am very disappointed in this product and always sorry to report such things but I try to help others in any way I can, and this is only my own personal opinion so please don't base your own decisions based on my own opinion, legally or otherwise I don't claim to be an expert but I do suggest further research before purchasing this item
I tried putting the old PSU back in but I'm now experiencing the same issues with both PSU's what is wrong with my PC?
Pull your hard drive and mount it into another computer. I think you might have shorted out the motherboard....
