Ok first, I recently bought an HP p6257c. I am looking to put in a video card and I know I'll have to upgrade the power supply, since the stock one is only 300W. I've been browsing the forums here and found other people had already asked for suggestions, etc. Well from those threads, I found these PSUs: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
these are my specs:
Athlonll X4 620 (P) 2.6 GHz (95W)
GeForce 9100 (integrated graphics)
mobo: Pegatron M2N78-LA
(of course it comes with one PCI Express x16 slot)
8 GB RAM DDR2 PC2-6400 MB/sec
and like i said my current PSU is 300W
and in case I missed anything: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01...
now that you have all my info, what i'm wondering is which PSU should i get and if i missed anything. I know some, but not nearly enough, so if there are any compatibilty issues or something i should know about before ordering the items, plz let me know. I am not a heavy PC gamer, right now the only real game running on this machine is the Sims 3, but i would like to be able to run other games (dragon age, halo 2, MW2 etc.), obviously, not w/everything maxed out
Either PSU you have selected will be fine. For the graphics card itself like Datman said is agp and will nor be compatible. Depending on you resolution you may not need the 4850, but it is a great card for the money.
The PSU is good. The difference between the cards in terms of performance is none. The real difference is reliability, which if based on that decision I would go Sapphire over powercolor. For 1080p you may want a more powerful card to be able to be able to turn up some settings. A 5770 would be adequate for that resolution and a 5850 would allow maxing out almost all games. The 5770 is about $60 more while the 5850 is almost $200 more.
