Power adapter question

Guest2 · 9 Oct 2011 at 16:53

I have given my mate my old ATI 5770 graphics card, with it is an 8 pin pci-e to 2 power connections.

Does he need to plug both in or just one?

It looks like the middle one on this pic.

What happes if he just used one of the power connections (because he only has one free?)

you need to plug both in. only having one molex connection and no PCIe 6 pin connections makes me wonder if the PSU is up to the job. what make/model PSU is it?

Is a Delta Electronics DPS-250AB-22

He said he's plugged one of the molex cables in and its working at the moment, installed with drivers on.

That PSU sounds a bit crappy to me. Is he at risk of blowing his pc up if using only one molex?

If it working should I leave him to it (even if only using one molex)

Suggest that he changes his PSU, if he says it's fine then leave him to it!
