PSU Replacement for a Hewlett Packard

About 2 years ago I bought a HP Pavilion a530n (plz don't laugh...OK, laugh) that came with a 250W PSU. I've never had a problem with it regarding power issues. However I recently purchased a Powercolor x800GTO that has a wattage requirement of 300W. Therefore I need to upgrade my PSU...

Problem is, I heard HP PSUs are extremely difficult, if not impossible, to upgrade. From what I've been told its due to custom connectors that they use to make the mobo incompatable with PSUs other than ones you order from HP.

Is this true? Some searching provided me with this option that claims to have the special 4-pin video connector.

Someone I game with also told me they have an HP Pavilion (different mobo) and upgraded their PSU with no problems. Help needed please...

  1. here is a couple of 180w units that define the pinouts here and here, it is +12v and -12v.

    You could cut it from the old unit & tap it from the ATX connector directly then use any mATX unit like this FSP Group (Fortron Source) FSP300-60GLS-R Micro ATX12V 300W which *should* be better than the usual OEM replacements...
  2. The new HP computer have same motherboard conectors than normal computers. Your motherboard could be ano ASUS, Gigabyte etc. estandar.

    The problem to upgrade is not the conectors. You could need to buy one new case with the power supply because case holes are not the same.

    One HP shop could remplace it with a wrkstation power supply. HP xw4300 have one 400w powersupply and is about 50$ to remplace. Ask him I can't tell you for sure if your case use the same design as Compaq Presario or bussines computers.


    Conesctor are the same. Form factor not. It adaptor could fit in the case http://www.newegg.com/Product/ShowImage.asp?Image=17%2D104%2D016%2D02%2Ejpg%2C17%2D104%2D016%2D03%2Ejpg%2C17%2D104%2D016%2D04%2Ejpg%2C17%2D104%2D016%2D05%2Ejpg%2C17%2D104%2D016%2D06%2Ejpg%2C17%2D104%2D016%2D07%2Ejpg%2C17%2D104%2D016%2D08%2Ejpg%2C17%2D104%2D016%2D09%2Ejpg&CurImage=17%2D104%2D016%2D02%2Ejpg&Description=FSP+Group+%28Fortron+Source%29+FSP300%2D60GLS%2DR+Micro+ATX12V+300W+Power+Supply+%2D+Retail
  3. You only need the special HP video conector if you have an old HP video card. Modern have molex or 6pin PCIe conector.
  4. Good info so far. I should have told you guys my mobo.

    It's an ASUS K8N8X-LA, otherwise known as the Diablo model.

    And here is what that extra HP video pin looks like.

  5. ok, i was in the same hole as u.

    I have a Sony Vaio with an ASUS Kirin. and the PSU blew so i ordered a new one. the issue is MircoATX PSU's can be too small. And full size ATX wont fit.

    i got this

    http://www.newegg.com/Product/Product.asp?Item=N82E16817192006

    WAYYYYY to small. but i got it in with a few sprace screws.

    You need a shorter Full size ATX PSU. which i dont think u will find.

    try this im not sure if it'll fit

  6. Thanks mate, I assumed OP need that connector!

    Lazy me, I usually check the HP support page, then get the part list from partsurfer. Looks like you're using part #5187-1098 "250 watt, Zinfandel PS2, Regulated".

    A bit of searching finds a replacement w/ details (dimensions & pinouts):
    300 Watt HP 5187-1098 (BESTEC ATX-250-12Z)
    looks like standard ATX 20-pin w/ AUX, 5.9W x 3.4H x 5.5D Inches (standard ATX).

    A look at the motherboard details doesn't show the old-school AUX connector so any ATX unit will work.

    So any one of these should do:

    SPARKLE ATX-300PN-B204 ATX 12V 2.0 300W $32 shipped @ zzf
    SPARKLE ATX-350PN-B204 ATX 12V 2.0 350W $34 shipped @ ewiz
    SPARKLE ATX-400PN-B204 ATX 12V 2.0 400W $42 shipped @ ewiz

    Are you sure? In the bottom left corner of the diagram it shows a 4-Pin slot labeled "AUX 1".

    Pengwin, my friend had the same problem with a Vaio. He got a standard size ATX PSU and managed to get it to work, but half of it is hanging outside the chassis.
  8. yah i didnt want it to hand out.


    the Aux 1 may just be a sound header u kno the core tha trun from your CD/DVD drive to the sound card
  9. So there is no consensus here then huh?

    Some say any PSU will do, others say I need the 4-Pin, some say I need a Mini ATX... :(
  10. Well you can google your HP part #5187-1098 for some replacement suggestions. Lots of hits on that "bestec" brand...
  11. Go to HP support and get one bigger power supply. If I'm not wrong your case uses the same power supply case than workstations. You have one 700w as the limit.

    Remember the cable is the same but the case are not standar.

    You can get one case and one standar power supply. There are a lot of mATX cases.

    And forgot the AUX1 conector. It is one audio conector.

    Looking at the diagram of my mobo, where would the HP 4 pin video connector go? I recall when I opened up my case, I saw a tiny cable that was tied off and not connected to anything. Maybe my mobo doesn't have a connection for it.

    If I do need the HP 4 pin, I found these two.

  13. i think that 5 pin video connector is just a 4 pin molex
  14. i recently bought a HP m7470n with Windows MC, it runs
    Athlon X2 4200+
    2 GB RAM
    TV Tuner
    2 Disc Drives
    300 GB SATA
    300W PSU ---> Some cheap piece

    i then bought an X1800XT and X-Fi soundcard, i knew i would need a new PSU for the gfx card, so i got a Antec SmartPower 2.0 500W, i had no problems installing it at all, it just slid right in, the only difference was it was considerably longer than the 300W PSU the HP came with so it was just a little tighter fit with the plugs into the disc drives but eveything else was fine and all pins were standard.
  15. HP power supplies have one speed control cable for the fan. In some motherboards there aren't conector fot it and the fan is always at full speed. The video connector is a molex with special form factor that fits in HP graphics cards.

    All other connectors are standar. Some cases are standar MC are standar case. other have compaq design and the power supply dont fit and others have one mATX "standar" form factor. It's easy to see, compaq form factor have the four screws in the squares .

    I am glad the OEMs are changing their evil ways and not using proprietary parts 8)
  17. So the HP 4 pin video would go into some onboard video thing on the mobo? My comp came with an AGP Nvidia FX card so maybe they tied the 4 pin off at the factory because I wasn't using onboard video?

    IcY, you probably have one of the newer cases. I have one of these.

    BTW, thanks to everyone for their help so far.

    Well look at the connector closely - does it have a blue power connector for the -12v? Probably not, since your PSU part #5187-1098 didn't call for the video connector.

    His HP Pavilion Media Center TV m7470n Desktop PC uses a newer 24-pin PCIE mobo, the MS-7184 (AmethystM) so he needs a ATX-300-12Z Rev. CDR PSU (according to partsurfer he needs the #5188-2625 "300-watt (Merlot C) regulated")- you can see the dimensions on this Bestec ATX-300-12Zwhich is 5.5"L x 5.9"W x 3.4"H for standard ATX size once again - along with the needed 24-pin ATX connector as well as a PCIE power plug.
    A bit more painful to find a detailed replacement part for that one :wink:

  19. i say get a PSU and try it.The End.

    makes life simple.

    Unless it blows out my mobo or other components. Then that's really the end.

    Makes life difficult.
  21. Go with your computer to the shop and test. If the power supply fits in the case you have new psu.

    Your motherboar needs ATX 20 pins. Get one that you can select 20 or 24 its easy new psu normaly have one adapter or one two pieces conector.

    If power supply fits in the case, the conector are standar in your motherboard.

    HP is using standar or semi estandar parts.Cases made by Compaq.
  22. You could compare your current PSU connectors to this diagram:



    that is how they should look if you unplug the connector and look at it head-on.

    If they match, you are running the standard ATX v1.3 for 20-pin w/ cpu connector and single-rail +12v. You can even use an ATX v2.x PSU since they are usually backward compatible with a 20+4 pin connector.



    It's not broken, the +4 pin part detaches for older 20-pin mobos...
  23. why not open the case up an dlook to see if tsi 20 or 24 pin
  24. Pengwin, the "Shorter Full-Size" form factor is called "PS/3", the "Full-Size" would be PS/2.

    Here's a PS/3
  25. bogut, I work on these things "for a living" and can tell you that any ATX power supply that fits WILL WORK. You will NOT spill the guts of the power supply, your parts will NOT go up in a cloud of sparks and smoke.

    MOST recent HP's and Compaq performance systems use a FULL SIZE power supply, a FEW have used PS/3 (the shorter version of a full-size), and HP converted its PS/3 systems to SFX a long time ago.

    PS/3 and SFX

    First I'd check to see if you have room for a full-sized power supply.

    The ONLY factor that remains is that most HP's with PS/3 or full-sized power supplies have a power plug opening that's too small to support any replacements with the plug in a slightly different location. Because of that, PICTURES come in handy for finding a unit that fits. Here's An Example of a full-size unit with high capacity that will fit the HP's cut-outs.

    If you can't find anything "cheaper" that fits, feel free to cut the hole out larger in the case.

    Why not just buy a freaking power supply that fits? Everybody is making this more complicated than it needs to be.

    I think you meant the cutout for dell cases. That one works great like PCP&C's dell replacement units that have the rocker removed.
    Actually it should work great for anything it is SPI/sparkle 8) and the auto-voltage sense for complete idiot-proofing is great for a dell replacement :lol:

    The pavilions use a full PSU cutout, not a whole lot of pics available on that particular model but there is a diagram on the user's guide found in page 5 of the Users Guide (5990-7510) which is linked from the a530n manual download section
  28. This was never a question about what will fit and what won't, and it was not about 20 pin vs. 24 pin. It was whether or not my current model uses the HP Video 4 Pin and if any PSU I buy to replace my current one would need that cable on it.

    4 Pin HP Video Connector
    http://pinouts.ru/Power/hp_power_pinout.shtml
  29. No, I meant the correct location for the small cutout in many HP/Compaq cases.

    You didn't know that HP/Compaq and Dell used the same socket location on cases with partially-closed openings? Well, now you do!
  30. Oh, in case you doubt my sound judgement, An HP case for your amusement

    That one came with a PS/3 power supply, but I replaced it with a PS/2. The power plug to one of the drives blocked installation of the larger unit, so I used a "splitter" with a right-angle end so that the plug wouldn't stick out as far.
  31. Wow, I've never seen that connector used before, every recent HP I've worked on had that connector unused, hanging out connected to nothing.

    Did you read the quote?
    Quote:
    This connector was actually used in some Pavilion models, in particular, ones that featured the EnSoniq soundcard. It is used to power the onboard power amplifier on these cards.


    It's been years since I've seen an amplified soundcard, you'd know if you had one. Most systems since around 1996 have used amplified speakers instead.

    Oh, in case you doubt my sound judgement

    that's definitely not the case - I meant the pavilions I have seen as of late - not all pavilions to date... bad wording on my part :oops:
  33. I don't think I saw in mentioned anywhere, did you try it with the 250watt ps you have? I bet it'll work, kinda like saying you need a 300hp truck to tow a 5000lb trailer and you only have a 250hp truck, then saying, hey, I need a new truck.
  34. yeah cool!

    c'mon now....lets not get off topic again

    The back of my case doesn't look like that. My PSU is located on top. Page 33 of this manual shows where my power supply is located and how to remove it.
    http://h10032.www1.hp.com/ctg/Manual/c00225826.pdf

    I checked and my sound card is NVidia, not EnSoniq, so that's a good sign. Last time I opened up my case I saw a wire tied off and hanging there. Most likely it was the HP 4 Pin.
  37. Yes, I was refering to the holes rather than the location, but it looks like your case has a larger hole so it can support a variety of power supplies. It also looks like it accepts full-depth power supplies, so you shouldn't have a problem finding an economical alternative. Fortron Source has a good 400W power unit that sells for around $40.
  38. My current PSU has a DEPTH of 5.5 inches, a HEIGHT of 3.5 inches, and a WIDTH of 6.25 inches.

    I would like to thank all of you who helped. From what I can gather I just need to find a PSU that fits and is around 400W.
  39. Yes, you can use a big power supply. So just pick something.
  40. anything is ATX format
