Do GTX 1070 Need Power supply? Is it necessery?

Solution


If it doesn't have a PCIe connector, it almost certainly isn't truly 500W.,

It's been covered off, you need a quality PSU with the appropriate connectors.

Power...
Yes - everything needs power.

In all serious though, I assume you mean the PCIe power connectors? Yes.
The PCIe slot itself can only provide 75W max, whereas a GTX 1070 is a 150W card - the only way to adequately power it is a combination of the PCIe slot & PCIe power connectors from the PSU.

You should ensure the PSU is fit for purpose and good quality. If it doesn't have the required PCIe connectors..... it's not.

If I've misunderstood the question, please rephrase.
 
Do you mean a power supply for your computer or the gtx 1070? If your talking about the computer well, yeah duh. It needs like 150W or so, so if you're getting other power eating parts I suggest you get at least a 500W psu. As for one for a gpu, there's no such thing, or at least that I know of.
 
I mean i'm totally lost... i have a ATX Switching Power Supply Model: ATX -500B and it doesnt have connection cable, how should i connect the GTX 1070 in to the power supply? I also dont have a 8PIN connection cable. Which goes to the Card
 
So what should i do? Should i buy a 8pin cable or a new Power supply? Btw the power supply box is 500W. My problem is i cant connect the card to the power supply.
 
a 500w power supply without any pcie connections is not a very good one at all. it is likely a generic unit that only provides 200w or so max!!

you will need a new psu to power that high end video card. if you need some help picking a quality unit, just give a budget and can easily offer some quality choices. the rest of your system specs is also needed to ensure the new power supply can power the whole system

^^ Some of the best "bang for your buck" (that won't actually go 'bang' like yours likely would).

All around $65, The SeaSonic would be my pick.

newegg sells just as many junk units as they do quality ones. it's important to know what you are buying when it comes to a power supply. it is the most important part of a pc. if it dies, it may take some or all of the pc with it. $40 can get a high quality unit and it will get a totally piece of junk.

again if you need some help with a quality choice, just say so and i can easily point you in the right direction. if you're outside the US, just post a local store you can shop at and can look there for you. prices and availability changes a lot from country to country
 
Its a pre-build pc

Motherboard: GA-F2A68HM-HD2
Memory: 16gb
Hard drive 1TB
PSU ATX SWITCHING POWER SUPPLY MODEL: ATX-500B
Case: Fierce Sandstorm Red

And i forgot my processor but its a AMD something sorry

 
Ok, you have a standard motherboard , so a standard ATX PSU will be fine, any of the ones I listed are quality options.

RobCrezz is right though.....regardless of the CPU in there, it's going to hold back a 1070.

The 'best' CPU in the FM2+ socket would be the 860K or 880K if you're pairing with a discreet GPU. I wouldn't go any higher than a GTX 1050TI in there.
Anything greater would be wasted.
 
There;s no CPU on the FM2+ socket (probably not even a single AMD CPU currently) that won't hold back a GTX1070 quite dramatically.

You're wasting money with that GPU, as you'll never see the full use of it.

The A8/A10 chips' main benefit is their onboard graphics, with lesser CPU performance. As I mentioned earlier, I wouldn't go higher than a 1050TI in there (a $130 GPU vs a $400 minimum for the 1070)
 
It'll 'run' with only a PSU upgrade.

If you want to use it to it's full potential, you likely need a new CPU+Motherboard+(probably) RAM+PSU. Looking at maybe ~$400-$450 for that.

Or, return the 1070 and pick up a 1050ti, which is more suited to your current build.
