Power supply help

I need to buy a new power supply to be able to handle a new video card and ram. Can I buy just any type? Are there certain types for certain computers?

I am using a HP a1600n (yes, I know it's crap...it's only for WoW), I am getting 4 gigs of ram and a 9800 gtx card. I planned on getting a 750 or 800 watt power supply.

  1. A good quality 500w or 650w would be good enough.
    Here is a good one for a decent price.

    Before you get any power supply I would check to see if your case accommodates ATX form PSUs.
  2. Why not get an HD4770 instead? It uses far less power for about the same performance, and probably wouldn't require a PSU upgrade.
  3. Probably not a great idea considering there is probably a 300W PSU in that HP and at best can run the stock configuration. I have an HP that has a similar style case and it is using a standard ATX PSU. You can always open it up and check for yourself, but I'm pretty sure it will be standard. Therefore since you are only using one card I would suggest something like...

  4. For a single graphics card, you wont need more than a high quality 450W PSU...
    Get something like this...
    Antec EA500

    And dont get the 9800GTX+, instead get the GTS 250...both the 9800GTX+ and GTS 250 have the same chip but the GTS250 has a smaller PCB and better circuitry and consumes less power...
  5. He would get away with a earthwatt 380 with those parts. but just get a beefyr model instead might need it eventually

    I was thinking the same thing when ragsters suggested the PC Power. The thing is the Antec you suggested is the same price and the PC Power is a better PSU, he would just have to deal with the rebate.

    I would suggest a 4850 instead of either the 9800GTX+ or the GTS 250. It performs the same and can be found for about $30 less.
    Here is one that's $79.99 after promo code and rebate. Code ends today.
  7. Please don't miss out on this deal. Newegg has the EA650w for $64.99 with no rebate required. Just use this coupon code (EMCLTMM25).

  8. ^+1
    That is a very good price on a very good PSU.
  9. What is ATX? How do I know if my computer can use it?

    I am getting the 9800 because I caught it for a very, very good deal (free from a friend).
