I'm upgrading the gpu simply because 4870 doesn't cut it anymore, I need something more powerful. Since there are various differences in currency and pricing, I will just say that HD 7850 1 gb is the most I can afford but I think I'd prefer something a bit cheaper. Also I'm not sure whether 500w psu is enough for it? I dislike nvidia so I would really appreciate some radeon suggestion.
Looking at the prices and various benchmarks I think that 7850 might be the best options after all, even if its bit expensive for me. The performance difference between 7850 and 7770 is really big for such a low difference in price. Thanks for help!
Without creating new thread, I would like to ask if this psu is enough for radeon hd7950 ?
yes, just about all 7950s will use ~175 watts at most when gaming. but in terms of overclocking both the cpu and gpu you may face some limitations; which CX 500 is it? there is one with 38 amps on the 12 volt rail and one with 34.
I'm not really good with psus but the max load on +12V is 38a according to the box I have before my eyes, so then I guess its 38 amps version?
ok, there are a few different CX500s floating around in different parts of the world; just checking.
just an FYI, a 7950 can get up to 200 watts with a crazy overclock; it would depend how high you have to set the voltage when overclocking. a 965 BE can get up to 175 watts ( +50 more than stock) which again depends on what voltage you need to keep it stable.
the 375 watts for just the gpu and cpu, not adding in the chipset, RAM and hard drive needs (~35 watts), is pushing that "max" power of 456 watts pretty close. oyu can run a 7950 "out of the box and overclock the cpu to keep it from being a bottleneck. but if you are looking to overclock that 7950 also, a 550 -650 watt PSU would be most desirable.
