Don't get cooler master power supplies, they are bad. If you want something cheap and reliable, I'd suggest Corsair CX 500.http://www.newegg.com/Product/Product.aspx?Item=N82E16817139027
As for HD 6870 vs GTX 560 is all about the games you play: they trade blows, and in the end they are even. On some games GTX 560 wins, and on others - HD 6870.
I already bought it
Got a good review here http://www.hardwaresecrets.com/article/Cooler-Master-GX-450-W-Power-Supply-Review/1234
After reading more in this forums about PSU (after I made this thread
) and a guy who helped me choose my build said this
" Cooler Master "450 watt" which has 35 amps on it's 12v rail for 420 total wattage.The GTX 560 only has a Thermal Design Power rating of 150 watt, so it'll pull around 13 amps and your CPU has a TDP of 95 or 8 amps. Even combined, you'll still have ~13 amps left to account for everything else connected to your computer. Although the CM GX 450W is capable of safely pulling it's fully rated 450 watts, so you have a bit more headroom than that. For comparison, an overclocked CPU and 560 system under stress only pulls around 380 watts total so you won't even come close to this number in normal usage."
I didn't fully understand till I read more about PSU's. That's why I had ask if radeon 6870 could use that PSU even if it says 500w requirement
Yeah that's what I have seen 6870 and 560 are pretty even I think I will just keep looking on newegg if they put a good deal from one of them and get that one.
sorry for talking so much about PSU on graphics card thread but just now learning all of this.
