8 pin + 6 pin GPU but only one 8 pin connector.

Hello. I've ordered a Gtx 1070 Ti online and only now found out that the gpu requires one 8 pin and one 6 pin connector. But my Psu only has one 8 pin. Will the GPU work with one 8 pin connected? Here are the specs: https://www.msi.com/Graphics-card/GeForce-GTX-1070-Ti-GAMING-8G/Specification

What's the exact PSU? A PSU missing connectors generally is missing them for very good reasons.

I don't know either. It's a pre-built PC I bought in a store. I only know it's 500W.

You'll have to actually look at it and identify it.

Without knowing, I can't say anything but no. PSUs thrown into pre-built are notoriously low-quality and I wouldn't risk a $400 GPU on one, sight unseen.

It says Eco Silent 500 on it.

It says Eco Silent 500 on it.

I would not run a $400 GPU on that. That's essentially a mediocre 400W power supply, a step above the pure garbage but not recommendable for this use (old, group regulated design that can't actually get its rated output on the +12V rail, which is what matters most these days). It's not surprising it only has the single PCIE connector.

Another thing to remember with pre-built systems is that the PSU, even though not always poor quality on some PC brands, will almost certainly not be sufficient for a GPU upgrade - -- they are usually just sufficient for the hardware that's in it when it leaves the factory.


The bottom line is you need a new PSU which has the two connecting cables that your 1070 Ti requires -- GPU won't work unless both cables are connected. -- don't go cheap on a PSU, use this opportunity to get a good one
