Upgrading to a Radeon HD 6570, PSU worries.

Last response: in Graphics & Displays

Hello you all. I currently have an ATI Radeon x1900 GT (very old card I know) and I am looking to upgrade to a decent card within my tight budget ($110). I'm a casual gamer (Starcraft II, no overclocking etc) so I figure that the ATI Radeon HD 6570 would give good value and performance. I'm worried though that I might not be able to run it because the recommended power supply watts is listed as 450w. Do you guys I will be able to use the GPU? My x1900 GT is running fine at the moment so if I can't use the 6570 HD, I'll stick with that in the time being. Specs below.

XFX HD-657X-ZHF2 Radeon HD 6570 1GB 128-bit DDR3 PCI Express 2.1 x16 HDCP Ready Video Card
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Specs:

AMD Phenom X4 9550 2.20GHz
6 GBs of RAM DDR2
500 GB hard drive (7200 rpm)
ATI Radeon x1900 GT 256 MB VRAM
Dynex™ - 400-Watt ATX CPU Power Supply
Windows Vista 64 bit Home Premium

Thanks.

Your Dynex "400W" PSU-shaped object is not really fit to power computer equipment: http://www.hardocp.com/article/2008/05/13/getting_best_...
The HD6570 would run happily on a good 300W PSU, but that's not what you have. Still, if it's powering a x1900GT it should handle a HD6570.
Normally, I'd recommend something a little stronger, like a GDDR5 version of the HD6670, but I just don't trust your PSU. If you can stretch your budget a little, get this 430W Antec Earthwatts for $40 shipped: http://www.newegg.com/Product/Product.aspx?Item=N82E168... and then add this HD6670 for $75 after MIR: http://www.newegg.com/Product/Product.aspx?Item=N82E168... (or $90 if you don't play the rebate game).

Thanks guys. Saved me from purchasing a card that I can't run at the moment :)  My x1900 GT (400 watt requirement) is running fine so I guess I'll stick with that until I can upgrade my PSU to a better quality brand and not that Dynex junk.

This should help in guessing how much wattage you need

However, remember that the quality of the unit makes a huge difference in how much power it delivers.


With my x1900 GT (x1900 series), their recommended PSU wattage is 387W but with the HD 6570, the recommended PSU wattage is 340W. :??:  Odd but yeah, I do have a poor brand psu.

Not really, newer GPUs tend to be more power efficient compared to its previous generation on top of being slightly faster. The HD 6570 doesn't really consume much power either.
