You get 2 of these in the box although I only needed one for my new graphics card where my PSU did not have the new type power plug. I am glad 2 are included as I could not get the pins in one to line up properly with the PSU plug but the other one went in no problem and works like a dream and saved me a new PSU. Not tried under load yet but if there are any issues I will edit this review. Edit I can confirm that under load using an i7 with an RTX2060 I have had no issues so far.
