Hi,

I have searched the internet and have raised tickets with Corsair and HP but I've not had a lot of success, I ended up here because I bought the PSU from Overclockers and their support page suggests posting on the forum. So here goes.
I am running an HP Omen Accelerator with a GTX1080, a Firecuda, and a keyboard, mouse and monitor attached. I was getting messages suggesting I use a more powerful PSU - the stock one that came with the Omen is 300w - so I bought a Corsair SF600.
Installation seemed pretty straightforward, but when I turned it on I got a half second of power and then nothing. I checked all connections (a 24-pin to the mobo and two 6+2s to the GPU) and all looked good. I couldn't work out what was wrong. So I undid it all and reinstalled the old PSU and now the same thing happens there - power for an instant and then nothing.
