Are HP power supplies upgradeable?


I just got through with an on-line HP person who told me that HP power supplies are not upgradeable...???? HP rep basically said: :non:

The rep HP rep had no answer when I asked "Why not?" So I asked "is it fused into the case?" Then the rep replied "yes" I asked "are you sure?" ... I asked this becuse it took the rep 20 minutes to find out what the power supply was ... then the person said "you'll void your warrantee" ... Then quickly typed "I hope I've answered your question" and went away ...

That just seems rediculous; that a power supply would be fused into a case. Reason for this thread is that I am looking at an HP Pavilion H-250 however the power supply is apparently crazy low @ 430W. To this computer I want to replace the 5770 with a gtx 470. Why on earth does HP always put such low power supplies into their computers as a rule?

Maybe I should just be happy with the putter the way it's being sold with the 5770:

  2. 250f ... not 'h' but the link was posted above.

    the reason i was wanting to use this for an upgrade i thought would be obvious: i7 860, 8gigs ddr3, wireless 802.11n ... for $1200 and the fact that the ibuypower and cyberpower customer reviews are SOOO incredibly Negative on Newegg about both companies! Basically that's all Newegg sells .. and those ZT's [?] and HP's

    i just wanted to bump up the video card if possible particularly to a high end nvidia card.

    anyone know if this MOBO can support a higher PS or for that matter what make the MOBO is??

  4. Thank you for that answer ... that'a pretty much where I'm headed.

    My only fear is that I know Nothing about how to deal with the BIOS on new build. Any good links where I can learn about that?

    I have been putting together a 'wish list' of items for a new build at the newegg site for some time .... i just really don't want to fry the MOBO and everything else because I forgot to do something. perhaps i should order the parts and have a local shop assemble it ... or is it really that easy to do?
  5. This is what I have in the shopping cart at the moment for a build I am considering. I have the gtx 260 core 216 in there for now as I am not entirely convinced I want the gtx 470 ... maybe a 480? in any event I think I would do the build with the 260 and wait a while to upgrade to the 4xx. I would like to keep the price to 1500 max. [?] but that's not entirely in stone just me telling myself that enough is enough and not to go overboard with $$ :non: $$
