Upgrading power supply for HP Pavilion P6604f

Hello everyone, I have a question about my computer which is a hp pavilion p6604f, whose specifications are

-Amd athlon II 220 2.80 ghz

-6 GB of ram

-750 GB hard drive

power-250 watts

Running on Windows 7 Home premium 64-bit

Y at - there no replacement HP power supplies for this computer, one that's more than 350 watts?

Im planning to buy a video card is a Nvidia GT 430, with the power of necessary minimum power supply of 300.

So, are there replacement parts, or I can buy any power supply? I don't know if it's ATX or Micro ATX

A power SUPPLY Antec TruePower PSU is huge and does not correctly match in a matter of HP.

Example: 3.4 "x 5.9" x 7.1 "(Antec TruePower) (due 120 mm fan) vs 3.4"x 5.9"x 5.5"(Antec EarthWatts EA-500D) (w / 80 mm fan) "»

  • HP Pavilion 500-326na: upgrade of power supply for HP Pavilion 500-326na

    Last year, I bought a HP Pavilion 500-326na. I now want to update its graphics and to do this, I need to power level. I want to upgrade to a CX500, but the specs say that his current power is "external". I don't know what this means, and indeed, I don't know if I will be able to upgrade. I see no reason why I shouldn't be, but everything I've seen only offers assistance on internal types.

    Thanks for any help.

    Hello

    Look at the power supply cord.  If you have a device of black brick similar to those for portable computers, then you have an external power supply. PC with external cannot be upgraded with the installation of an internal power supply as a Corsair CX500 according to HP internal.

  • The upgrade of the power supply for HP Pavilion M7570N

    The reason I'm on this forum is when I called hp support and gave me a stupid answer of not being able to change the PSU because of software...

    It's a high-end desktop PC.  No doubt he will come with an ATX PSU with 5VDC, 12VDC and 3.3Vdc output rails.  I'm not familiar with the Interior of your PC, so I'll give you two General configurations of PSU layout.

    1. design intermediary such as PC Power & Cooling with one or two 80 mm fans to expel air through the PSU.

    http://www.Newegg.com/product/product.aspx?item=N82E16817341011

    2 down-draft design as Cosair 450VX with a 120 mm or more huge blowing fan case in the heat sink and the motherboard of the PSU.

    http://www.Newegg.com/product/product.aspx?item=N82E16817139003

    If the power supply is at the top, back or side of the PC, then a power supply down-project will do a better job to remove heat from the PC.  If the power supply is in the middle of the PC, then go with an intermediate design.  This design will generate more noise at higher load, since the smallest fan should turn more quickly to transport the same amount of air in a 150 mm or 120 mm fan.

    Looking for a nominal 80% efficiency POWER supply.  Detachable power cable is a bonus to maximize the air flow inside the PC.  Make sure the power supply is delivered with the right type of power connector to drive you GPU.  All modern units of quality with 20 + 4 and 4 + 4 key cards.  If you do not plan to run graphic dual with a high range GPU, so it doesn't matter what quality 80 watter 380 power SUPPLY Antec, Corsair, Enermax and Seasonic PSU will be enough.  You will need to back up POWER supply to 450-550W, if you run two graphics cards high-end.

    A good 450W PSU is a good compromise because it is more effective when the PC is idle and has enough power to run two GPUS.  If you want to save $ on electricity, then get a smaller power supply (range 300-350W) because these units reach the level of efficiency of 80% around release of 65 to 70 watts.

  • Update of power supply for HP Pavilion 500-056

    I want to upgrade to a discrete graphics card, but the 300 watt PSU is not enough.  It is not one of the standard sizes such as ATX12V, EPS12V, SFX12V (small footprint), LFX12V (low profile form factor), or TFX12V (slim form factor).

    Does anyone know of a specific diet that can fit in my computer case?  Without my ability to be upgraded will be severely compromised.

    According to the specs of HP Pavilion 500-056 desktop PC product page, your computer uses a power SUPPLY ATX12V PSU which is 150 x 140 x 86 mm (5.9 x 5.5 x 3.4 inches) in size. Please consider replacing it with a Corsair CX500, CX600, CX500M, or CX600M depending on your graphics card needs.

  • Replace the power supply for a Pavilion a140n

    How to install a new power supply in a HP Pavilion a140n? Is there a step by step guide?

    Zz30fg, welcome to the forum.

    Is the model you list correct?  I can't find anywhere.

    Before you start, I suggest that you measure existing power supply unit (PSU) to make sure that the one you choose to insert in the space provided.

    The first thing you will do is turn off the computer.  Disconnect all devices that are connected, for example, keyboard, mouse, printer, etc.  Once done, remove the side cover of the case.  There are two or more screws on the back of the computer that you have to remove.  Then slide the side gently to the rear.  Put it somewhere safe.   Be sure to touch the metal inside of the case before touching any components.  This will eliminate static electricity (ESD).  Now you can disconnect the cables from the PSU.  This is where it gets a little tricky.  I normally take a picture of the connections and mark them as clearly as possible on the motherboard.  Believe me, you'll be much happier if you do.  Once this operation is complete, it is time to remove the (4) screws that hold the power supply in place.  Hold it with care.  If it falls it can damage other components.

    The new power supply will be marked with the appropriate connector cables.  At this point, it's just the opposite of what you were doing to uninstall the existing PSU.  Install the power supply into the case.  Do not overtighten the screws.  Make sure that the cables are inside the case.  Once in place, carefully connect all cables to the appropriate connectors.

    If you have any other questions, I will watch this thread for you help.

  • Aurora-R4, seeking to upgrade power supply for a better quality of power supply that is not a brand of Dell?

    OK, I have a R4 Aurora, and in my view, that it comes with a power supply of 875 watt. Not 100% about this though. For now, I want to upgrade the power supply to a power supply, so it can support say double cards video in better quality SLI mode. The problem is that the PSU 875 does not have a rail system unique to 12 volts to 50 amps of power support to handle difficult loads of power and provide ample cooling in the power supply. What I would do in the future, it is out of the current PSU, I now and looking to buy a decent POWER supply unit elsewhere. Reference Dell sells a power supply higher than I can use existing wiring, or should I find another brand of PSU and seek to replace the power wiring? And how is it difficult to install if I have to use a different power supply with a different wiring? Installation instructions?

  • Upgrade power supply for Pavillion 9040n

    Hello.  My PC is a 9040n Pavilion with Vista.  Full sheet here http://h10010.www1.hp.com/wwpc/ca/en/ho/WF06b/12132708-12133156-12133158-12133158-12133158-80631744-...

    I'm moving my current card of the chart (NVIDIA GeForce 8400 GS graphics card) to a Radeon HD 6450.  This means that I also put to the power supply.  Can anyone recommend a diet around 600w that works?  Don't look for is not the cheapest, but I like to keep around $100 or less.

    I saw a couple that seems like they would work, except that the fan is at the top, like this: http://ncix.com/products/?sku=59908and I guess that's out of the question for my PC.

    Thanks for your suggestions!

    Kevin

    If you look at the blades of the fan in the power supply, you will see that it sucks air through the fan and pushes the air components of the PSU, then the vents next to the plug/socket and power switch. Place the power supply on the top of your computer case with power supply on the side fan draw the air out of the case will not blow hot air into the case.

  • Need help for upgrade power supply for HP H8-1445

  • upgrade power supply for h-rs880-µATX

    I would like to move power from 300w to 450 or 500 more. Don't know what power supply would be compatible for H-RS880-µATX motherboard.

    Kako571111, welcome to the forum.

    When a help request, you must always include the brand / model of the computer or the monitor. This information is necessary for us to review the specifications for them.

    I sugest measuring the current power supply (PSU) and comparing them with the one you choose.  You can buy one that has a quantity of power.  However, I do recommend more than 600W.  The computer uses only the amount of power required to carry out.  A 600W unit will give you possible shared future updates.

  • The upgrade of the power supply for a HP Pavilion 500-054

    Hey people,

    I'm changing the 500-054 flag so that it can play a few games, not a hardcore gamer, just want to be able to play the occasional game. I want to get a lower end external video card, but this requires a power supply greater than 300. I am looking for a new power supply for my computer, but I couldn't find one for the 500-074. Are the ones that will work for my computer or I am a hopeless case?

    Thank you

    A standard ATX power supply will work. Please look at the Corsair CX430, CX500, CX600, or their variations of modular cables for your needs.

  • HP Elite 1090-T H8: seeking your suggestions for upgrading the power supply for a new video card

    I have a HP EliteH8-1090 t who is about a year, but with an AMD Radeon HD 6570 low power graphics card and a 450W power supply. I want to upgrade the 650W power to support the installation of a replacement graphics card.

    I tried to replace the HP 450W with Corsair TX650 and Corsair TX850 food. The system appears to power (DVD drawer opens and closes, the hard disks spin, fans run) with either a Corsair, he's stuck at this point. My system is unable to enter start mode when either power supply is installed - it seems stuck in a mode of seed, and the monitor still asleep.

    Can someone please advise on a compatible power supply for HP system? I'm puzzled by why a simple exchange of a power supply does not work. Just like a record, the system has a card mother Pegatron IPMTB-K (Truckee).

    Thank you!

    No problem. I wish you good luck with it. On a positive note the HX650 is a much better than the TX650 ILA unit internal quality and what I like is the best it's quite fan fan much quieter than the TX650 while helping your organization of cable being modular and help keep temperatures cooler in your computer case.

  • New power supply for Pavilion a1230n

    I need to replace the power supply on my Pavilion a1230n.

    The current source is a Thermaltake TR2 430W (430 watt), model number W0070RU).

    I would like to find a better diet quality and rated at 500 watts continuous.

    Food will sit just above the case without space above it. So I need to have a power supply either a front opening, or an opening on the bottom.

  • Power supply for Pavilion a6720f?

    Hello. Is power supply for an a6720f a standard ATX, or something exclusive? I need to know.

    Thank you.

    This is a standard size ATX PSU - 5.5 "by 5.9" by 3.4 "but confirm this by opening your PC and by measuring the PSU.  Go back to the bottom of all the cables coming from the PSU for the endpoints so that you know which links are necessary.
