Hello everyone, I probably will buy soon a HD 7870 XT w Boost and sell out the existing HD 7850 OC. The reviews say its maximum power consumption, while fully overclocked will be maximum 225-245 watt. My rig is given in the signature. Probably I'll in the future buy an i5 3470(77 watt TDP), one SSD and one extra RAM. Judging by the specifications you can see I'll be able to run my computer with a good quality single rail +12V PSU of ~450watt. For example Seasonic S12II Bronze 430 W.
In the above link you can see the PSU performs great when 345 watt on the +12V rail is extracted from it. And on the next page on that link shows how it performs when more than that is squeezed out of that.
Now I know the basic facts like we should have some extra room for wattage when it comes to buying psu and generally they perform at their best when under 80% load etc. So I may also buy a 500/550watt psu. Now my question is--
1. If I buy a psu of ~450 watt is Seasonic S12II Bronze 430 W the cheapest one maintaining great quality? I've fairly gone through all the recommended psu(400-499 W) list and I find it the cheapest. But in case I missed something or any new product that is not in the list and I can try??
Also note that this psu is actually too good for a ~60$ psu. "Flawless" according to the review. So I don't necessarily need a flawless one. A psu reliable enough not to burn out my PC any day will suffice for me.
2. If I buy a ~550 watt psu I've found 3 possible candidates. XFX core edition 550 W, Seasonic S12II Bronze 520 W and Rosewill Hive 550 W. I don't know much about Rosewill and other two brands are traditiolnally more popular. But three of them are more or less equal right?? I mean in terms of quality??
3. Anything else in 500-550w range u wish to recommend which will be cheaper with more or less equal quality?
4.. Does the warranty depend where I buy from? In newegg each product(PSU or not) have specific info on warranty under the 'Details' tab. But in Amazon I cannot see anything written explicitly for many products. So does it matter on the store I buy from too or only the brand of the product?? Some products I'm looking for are cheaper in amazon. Some products I'm looking for are cheaper in amazon than newegg.
5. In amazon when I search for the XFX core edition 550 W, I end up at
As you see the title doesn't say anything about core edition or pro series. However the serial P1550SXXB9 seems to be identical with the core edition product given in the XFX website with hyphens omitted:
So I guess these two are actually same right?
