Modified HP

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:
which according to the thread i found it on, should fit (as long as your current box measures: 15 cm wide x 14 cm long x 8.6 cm high)
and this card:

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:

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

thank you

  1. anyone?
  2. I like the Corsair PSU's personally, they have a single 12v rail. 550w would be better but 450 is OK.
    The OCZ's are good also.

    The card you selected is for AGP and won't fit in your motherboard, one of these will be better or a 9800GT.

    POWERCOLOR AX4850 512MD3-PH Radeon HD 4850 512MB 256-bit GDDR3
    SAPPHIRE 100245HDMI Radeon HD 4850 512MB 256-bit GDDR3
  3. 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.
  4. thanks for the input, well i have a 23 inch HP monitor,

    the max resolution is 1920X1080

    what do you guys think about this PSU?:

    also, one quick question: besides the brand name, what's the difference in the cards you suggested and is either one better?
  5. 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.
  6. If not a heavy PC gamer, a 5770 would probably be sufficient (considering how much more a 5850 costs).
  7. That's a good PSU. Not much difference between the two cards, the Powercolor uses the better capacitors.

    If you do consider a 5770.
    Best PCIe Card: ~$95 To $180
  8. alright well thanks for all the input so far, so after looking around some more i think i'm going to go with these:
    any more suggestions/opinons/things i should before i order?
  9. Don't get the xxx edition and get the normal one and OC it yourself.
