The 7870 is no problem to use with a 500w. One thing i would check, is that the psu have the right(6,8-pin) pcie cables for the certain card you like to get.
570 can also be runed with 500w psu. Is it a good quality psu you got, and how many pcie cables does it have?
If your psu only have one 6-pin pcie cable i suggest you upgrade the psu to a 750-850w. Then you are ready for sli or cfire later. Corsair, Seasonic, enermax are good quality brands for psu's.
Guru3d reccomends this:
On your average system the card requires you to have a 600 Watt power supply unit. Though the card itself only needs about 213w at full load. It all depends on how mutch hardware you got, if you overclock and how good your current psu are...
Both reference cards have 2 pcie 6 pin connectors.
7850 on top and 7870 underneath.

It depends on how that 500W total is achieved.
Most of the cheaper / older PSUs don't allow much of the stated power over the 12v rail(s), which is what most of the components in your system run from.
Check the sticker on the side of the PSU and see where the power if available.
For a mainstream CPU (<95W TDP)and a 570 you'd be wanting about 450W on the 12V rail, which is 37.5a.
If it's a cheap PSU that came with the case, I wouldn't risk it. Such things are rarely able to achieve the power they say they can except @ 15 degrees or something silly.
If money's tight, it might be an idea to drop to a 560Ti and get a new PSU like http://www.aria.co.uk/SuperSpecials...US+Gold+Modular+Power+Supply+?productId=41315
May seem pricey but a decent PSU will last and give you peace of mind that it won't just blow up and take £1000 worth of computer stuff with it

Yeah i agree with what you say. To many peeps take to lightly on the psu pick, and many times it only leads to problems. A psu is like the heart in a pc so choosing a good one is important.
