So i got a brand new rig :
AMD Fx-6300 3.5 Ghz 6 cores
8GB Ram (4x2) 1333Ghz
1TB HDD 7200Rpm
500w Antec PSU
But i thought i might be able to use my older XFX ATI Raedon HD 4870... But now it heats u to 100 C. even the average temp is 70 C. and i have a feeling that it will damage my PC bcz it makes my cabinet soo hot that i can even touch it so i need a dirt cheap Graphic Card (bcz i dnt have any cash left) to play games like World Of Tanks, COD etc..
The HD 4870 is somewhere between the 6670 and the 7750.
Btw I had the same problem with my 4870, so I lowered its voltage by a small amount and its temperatures are now in check, it's working like this for about 2 years with no issues. The software I used is ati tray tools, google it if you want to give it a try.
Anyways, try what doron said and lower your voltages. If not, look for a used graphics card or ask around family and friends. I wouldn't buy a $50 card. Save up a bit until you can at least get a $100-$150 one...
For computer cases, sure. I wouldn't ever buy/use a power supply from them though.
Why not? Antec is one of the big 4 PSU companies that I would recommend to anybody. Very reputable brand.
Mostly because I already have 2 from Corsair. So, partially because I don't need one, and partially because I ruled them out when I was looking earlier. In another 6-8yrs when I need a new PSU again I may find that things have changed and I may choose them, but for now they're off the radar.
