you need to put some consumer on 5V cable, i have same PSU, and i put a old cdrom on 5V and never shut's down.
Are you sure? If this is really true, that is just stupid. Not every machine needs the 5v. If I build a GPU mining rig running off a usb flash drive, it won't need the 5v. 6 pin to the GPU, 8 pin to the cpu, and 20/24 pin to the MB all 12v.
yes i'm sure,
i have 2 Corsair VS Series VS650 650W , and if i'm not puting nothing on 5V they keep shuting down.
here is a link so you can figure out why
