3070 GPU advice

[Mr Dan Dan]

I'm hoping someone can help me cos I feel helpless right now.

I managed to get a 3070, the gigabyte geforce one and I was told a corsair TX650M would be plenty to power the whole system (MSI MAG B550M MORTAR WIFI, 32gb corsair vengeance lpx RAM 3200, Ryzen 7 3700x, FUMA 2 cooler. Am I right in thinking the pcie cables that come with the PSU won't work on the 3070 cos it needs an 8 pin? Do I need to plug the 6 pin and the 8 pin or just the 8 pin and can I get an adapter that would connect a 6 pin and make it 8 pin. Sorry if these questions are dumb but I had a really good feeling about building my first pc and so far I've had nothing but trouble.

you should have 2 cables that have a 6pin with a 2 pin, also who told you 650w psu woul dbe enough? nvivida says you should use a 750w

I've tried pushing the 6+2 pin in and it won't go in, I've tried pushing pretty hard but I don't wanna try any harder in case I break it.

Someone on box recommended the 650w

Of course it goes in. Have you looked at the connection to see exactly which pins go where?

A 650W PSU is more than enough for 3070.

One of my systems is currently running a 3070 and 3700X with a quality 450W PSU.

These are 220W GPUs using only a single 1 x 8pin for the FE version. There is only so much power they can draw.

Well I lmao at you because my 3070fe box clearly says 650 watt psu minimum.

I was going to run mine on a 450 watt too but my other half persuaded me from doing it.

Better safe than sorry but that isn't to say it just won't run on a 450.

My 3070 reports around 250 watt when overclocked.

They can be made to draw 300 watt.

12 pin is good for 300 watt.

Fair play for using a 450 watt. I was very close to doing the same. Glad I didn't though, I can overclock without thinking about it and upgrade to a beefier CPU later.

Just push it in mate, don't be shy. 650w is plenty. Worst case you undervolt it slightly.

Mate dont force anything if you break it or worse hook the wrong power in and power up it's fried.
Can you post a picture of the cable ends ? Might help people direct you.

Daft question, have you tried the +2 plug on the other side of the 6 pin?

Looking at a picture of the connector, it looks like the +2 will reach both sides of the 6 pin.

But please do post a pic as Tiny_D suggested.

The card only has a +9% power limit. If you are overclocking it, it aint much.

I have a 3070 FE + 5600x with corsair tx550m. 0 issues so far, so even 550w is more than enough. The 650W recommendation is with a 10900K for which, 600W should be minimum.

Plug 1x 6pin+2pin (the bit dangling from the 6pin) from your PSU into the 8 pin socket on GPU, then plug the other 6pin (leave the +2pin out) next to it. If you are struggling, plug the 6pin part in first all the way then the 2pin bit after, don't try to do both at the same time.

Whether the 2 pin goes in first or 6 pin depends on the PSU. On some they even clip together beforehand.

Have a look at this re installing the GPU power. Has a good close up of the 6+2 cable ends.

Not sure what point you’re making.

Normally they show 227w at stock. Add 9% and you’re approaching 250w.

I think most clip together and you have to put them in at the same time.

Should just make them all 8 pin or whatever and have done with it. Make it all standard weather they need the power or not.

Cheers everyone for the advice. It was tight, really tight but I perservered and it is now fully inside. Thanks again

220W is the TBP. It might fluctuate a bit around that but 220W is the TBP. Add 9% and you get 240W which it may fluctuate around.

Also approaching 250W when overclocked (more like 240W) is nowhere near the 300W you claimed.

@Mr Dan Dan which gigabyte card is it ?
