Hi, I got a Corsair 500W power supply running an i5 3470 on Gigabyte Z77-D3H and I'm not entirely sure if it will give enough power to run a Gigabyte gtx660 OC, or the Sapphire HD7870... What i don't want it to do, is give all it has and blow while frying my entire system (that wouldn't be good) so any answers are welcome :D 

More about : 500w psu gpu

I have a Corsair CX500M and I'm running a Sapphire 7870 GHz card with no problem. :)

I have seen many 7870s run on 500w psu and due to the reliable name and the processor you have it should be fine again in this case. I infact have the same sapphire gpu but higher psu because my awful processor. You'll be fine

Thanks guys! :D  I didn't want to make any foolish mistakes while buying the GPU's but thats sorted now. :)  Just one more thing... should i get the gtx660 or the Sapphire 7870? I want to be able to run games like BF4, GTA 5 (if it ever comes out on PC) and so on.

With my 7870 GHz I was able to play BF4 and AC4 on ultra settings with little issue. The 7870 is slightly faster than the 660 as well.

Well sounds like the 7870 is the one I'm going to go for in this case. Been using the intel integrated graphics and it's been a pain in the a** xD Thanks again.

The 660 and 7870 perform very similar in terms of gaming performance, for example heres a chart from a review on Tomshardware http://media.bestofmicro.com/U/8/352304/original/Crysis...

the review can be found here: http://www.tomshardware.com/reviews/geforce-gtx-660-gef... and includes other benchmark charts for 660 and 7870.

One important thing to note is that the 660 uses 35W less of power than a 7870 so if you are REALLY concerned then you can always go with the 660 but bare in mind that generally a 660 is more expensive.
