I was wondering if my current power supply (Cooler Master RS430) is enough for my system if I buy an HD4870 graphics card.
Intel Core 2 Quad Q9450 @ Stock (with stock cooler)
OCZ 4GB PC8000
Samsung 400GB SataII hard drive
MSI P35 Neo2-FR
Currently a X1950Pro card, but I'm about to buy a new one
My Coolermaster power supply has 14A on the 12V1 line and 15A on the 12V2 line. Does anyone know if that's enough to run a HD4870?
Thanks for your help. The sticker says exactly what I said (because I looked it up before I posted ), so 29A combined. So that means my PSU could handle it? It's a Coolermaster PSU, so not an extremely cheap 430 Watt one, so I think those are constant amps and not peak amps.
And do you think my PSU is powerful enough to run the card along with the rest of my components? I'd like a few more replies as confirmation, because I don't like to be surprise that I do need a more powerful PSU. If I do, I'd go for an HD4850 instead.
If you look up the 4870x2 they say min 30amps on the 12 rail so I don't know where you got the 11amps from? also maybe the single is less I have lots of USB annd hard drives extream 3ghz cpu and the 4870x2 and a therm cpu cooler and a few fans when I looked up all the power my system should have a 834w power box I did have a new enermax liberty 620w and had some funky things going on and blamed Vista but now I have a PC POWER & COOLING 750W and no more problems runs smooth as can be. all the problems went away. I have a BMW 540IA and when the battery goes it does funny things also so maybe power is very important! here is a link you can add up the power your system uses, http://extreme.outervision.com/PSUEngine
Thanks for the link phantomsys. I entered my complete system and added a few modifications I might do in the near future (such as two HDD's instead of one, and a few casefans), and it says the system would use 386 Watts, so 430 should do fine I think.
