Hi guys,

I have a Gigabyte GA-H170-HD3 LGA 1151 Motherboard. Will it support a Galax GeForce GTX 1070 EX 8GB Video Card without needing to be upgraded?

Ahh... I forgot to mention that one: GOOD QUALITY PSU
Of course you can get GTX1070 and i7 running on a 430W PSU, It's Seasonic PSU. They are well known...

Uhh if it's a good quality PSU it does not need to be 500W.
Running a 430W seasonic fanless with my i7-3770 (lightly overclocked) and gtx 1070 for a while now with absolutely no stability issues. I've tested with a prime95 and furmark simultaneously for a few hours without an issue. Testing using a kill-a-watt I think it peaked around 250W max.
 
POWER: max consumption with overclock appears to be about 180W for the GTX1070

Systems vary, but most Intel setups don't use more than 150W so in this example it's 330W so sure a 450W (ish) quality PSU can work.

If buying a new PSU I'd invest in a quality unit as an investment. A good one can last a long time (and less likely to damage your components). One example is an EVGA G3 650W (the Wattage is overkill but you can use ECO MODE to disable the fan. You need 650W so 50% is 325W and thus unlikely to require the fan to turn on).

Note some PSU fans are noisy. Some aren't. It's FRUSTRATING as I'm noise sensitive and the EVGA G2 was too noisy for my tastes (though luckily the ECO MODE works fine).

My CPU is an i5-6500. RAM is 8 GB (but I might be upgrading that to 16 in the very near future).
My PSU is... an Antec something-a-rather; 900w, apparently, at any rate.

Of course you can get GTX1070 and i7 running on a 430W PSU, It's Seasonic PSU. They are well known for reliable and built with high-quality components.

I also use a high-quality 400w PSU to power my old C2Q+GTX960 build. No problem for 4 years (I swapped the PSU on 2013, if I not wrong) until the motherboard died, I'm surprised that my FSP PSU is not causing the problem and still going strong.

And for the OP, No need to upgrade anything. Just plug it into your motherboard, install the driver, and enjoy.
Your i5 will not bottleneck the 1070.
