be Quiet 530w PSU enough for Gigabyte GTX 970 Extreme ?

[alohamasto]

so my setup is right now is
i5 4670 @3.4ghz
Gigabyte GTX 670 oc 3x cooler
1 hdd
2 modules of ram at 1600mhz
and the Be quiet Psu 530w bronze plus.
so far(more like 3 years) i havent encounter any problems. So am i going to be ok with the that upgrade ? I know in fact that the 670 draws more power that the 970 but im seeing some others posts that recommend at least 600+ watt rated psus . thanks

You answered your question on your own: yes, will do.

Agreed - the GTX 970 consumes less power than the GTX 670.

That said, the Gigabyte version may pull a little more than the standard one, but one site I came across said that it pulls an estimated 170W, which is the same as the GTX 670.

You won't have any problems with your existing power supply.

You would need to use a Molex adapter for the 970. You have 4 pin+8 pin VGA power connectors and you will need a 2x8 pin VGA connectors for that model. A 530 W supply should work out fine being it is a decent unit.

I wouldn't recommend that adapter.

That said, it seems the Gigabyte GTX 970 Extreme uses 2 8-pin connectors? That seems like serious overkill for a GTX 970.

Does your PSU have 2 8-pin or 2-6+2 pin connectors by any chance? Perhaps that's why Gigabyte recommends a 600W power supply? Because they assume any smaller power supplies won't have the 2 8-pin connectors, I guess?

A normal 970 uses 2X 6pin which I thought was a overkill for the wattage of the card, so 2X8 yeah I would agree that seems like a overkill.

Thats is one of the better adapters since it uses 2 Molex over just one, it does the job as long as you make sure everything is tight fitting. I normally just replace the PSU and avoid adapter all together but not everyone is willing to drop another $60+ to upgrade a GPU.

Never use Molex adapters. If your PSU doesn't have the required connections, get a quality PSU that does have them. Pretty sure that PSU has 2x, 6+2, connections, though.


Edit: If this is the PSU you have, you have the needed connections.

You would be correct no BS adapter needed.

yup the L8 pure power is the psu that ive got , In general ist stated that the 670 draws like 30w more but on reviews like this one https://www.techpowerup.com/reviews/MSI/GTX_970_Gaming/25.html it shows the opposite, that the 970 draws more

 

[logainofhades]

Highly overclocked models are going to draw more power, than a reference design. That is a given.

For that particular model, I am not sure your PSU is good enough, without running it at near reference levels of clock speed. PSU and that card, you might be just as well off getting a GTX 1060 3gb. Similar performance to a 970, and even less power hungry.

Agreed - but 145 stock, vs 2x150W for the two 8-pin connectors, and the 75W available from the slot? 375W total?

I don't think it's going to draw 2-1/2 times the original amount of power. I can't imagine it surviving anything close to that.

 

[7664stefan]

No, I found around 300W max power consumption confirmed for this card. Honestly, this would not be my first choice.

EDIT: wait, is that just from the card, or the whole system? Because if it was exclusively from the card, then aren't the idle measurements shockingly high?

EDIT 2: Maybe not, the R9 285's load number looks like it's right at where I know the TDP rating is for that card. Ye gods, Gigabyte, it's not a contest to see who can draw the most power!
