I'm buying a pc and I wondered:

If I get the 5770 would 450W be enough?
If I get the 5830 would I have to upgrade? Would 600W be enough?

I'm afraid I don't know the brand of psu, it just says the wattage and then 'Quiet 80 Plus Dual Rail PSU'. I don't really know much about power supplies, so please keep answers easy to understand. :whistle:  :D

For a 5770 450W is ok - set as the standard system requirements to run it: see link below

If you want to overclock it and/or your CPU then I would go with a 500W or 550W.

For a 5830 then 500W or 600W if you want to overclock it and/or your CPU:

Might I add if you are willing to get a 5830 it may be worth the extra 50 odd quid and go for a 5850. Up to you mate.

I personally recommend Corsair PSU's

Hope this helps

Thanks guys, I'm not really a hardcore gamer, more of a low to mid-level gamer. :) 

So do you think I should choose the 5850 with the 600W or the 5770 with the 450W?
Th 5830 would sort of be stretching my budget, but I don't know if the 5770 would be enough to last for a few years with 450W.

i would say get the 5850 unless u can wait a week and see what the prices will be when the new generation of ATI cards is released.

Swedens biggest computer website ( have posted preliminary prices of the new cards and according to those u will get a 6870 for the same price that u get a 5850 for today.

Note that this is PRELIMINARY prices in SWEDEN and they may change and/or be different in your country.

the ATI 5850 actually uses less power then an ATI 5830, so a solid 500w will do the job

So 600W is enough for the the 5830?

600W for a 5830 should be enough yes.
i have a Corsair TX650W to run my rig and then i have overclocked i5 and 5850CF.
