• R104 - power supply works, but the dead unit

  Hi I have a Readynas 104 about 2 years and it just stopped working and will not. The power supply shows a green light, suggesting it is fine, but the box itself died. Any ideas how to fix this problem or do I get it looked at under warranty? Also I have a thought to replace it with another more powererful Readynas. If I simply move the disks to the new unit will be able to prepare the raid 5 array, I had the installer on the R104 (4 x 3 TB WD) Red readers

• Legacy with defective power supply unit. Looking for replacement source

  RND4000 (ReadyNAS NV + v1 [v3]) group legacy with a power failure. Looking for replacement source. Not after replacement free of charge since it is obviously out of warranty and end of product life. However, it is a little expensive Kit to replace. If I did, I would still want to use it as a backup of synchronization for the new.

  I was unable to find any power supply corresponding by the name given to the unit (ST-220FUB-05F), all the results of my research resulted in a power different with smilar looks and namesake. Main differences are slight changes in the output rails, different output connectors. Also include a fan that mine didn't, perhaps a clue to the failure there.

  I was shocked to find that he was / is none replaceable fuse in the power supply and if there was a gauge commonent that he was unable to do the job because a cracket big mosfet to clean his radiator, think that's what it is, hard to see in here. Unable to find a replacement, I'll have to try to replace the component that is visibly damaged. Not easy because it's crowded in there and may fail because there are perhaps other failing components that didn't explode or evacuate. I really need ot get this unit backup and running.

  Help, please. Consider the purchase of an equivalent of second hand RND4000 for parts. See you soon.

  Hello EkDor,

• G4 MDD power supply Issue

  My MDD was recently stop only two or three minutes after a cold start. The power led lights up, the gray screen with the Apple logo appears with the spinning wheel, but then the machine suddenly loses power as if the power cord was disconnected. These are the things I've already tried:

  1. Removed the PRAM Battery
  2. Disconnected all devices except the keyboard and the monitor
  3. Tried a different power cord

  Start in safe mode did not help. The fans are all running, the red LED lights on the logic board and disk drives seem to work. This could be a power supply issue or a problem with the motherboard and is it possible that I can definitely identify the problem without being able to start the G4? The startup time has been considering more when everything worked last week, would that be a clue? I've owned this machine for more than twelve years and it put to the test so I wonder if it's time to retire him.

  Thanks in advance for any help you can offer!

• 29W power supply will work for iPad 9.7 Pro

  My iPad Pro 9.7 inches provided with a power of 10 watts. It takes about six hours is responsible for the depletion of the layer to be 100% responsible. I would like to be able to do it faster. I noticed that the iPad Pro with a larger screen has a 29 Watt power supply available in the Apple Store. I bought this with the cable Apple to convert USB type C USB 2, which I am connected to my Flash a USB cable.  When I try on my Pro 9.7 inch iPad it charges no faster than six hours. Anyone who has tried using a larger power and they have managed to improve the loading time?

  The smaller iPad Pro does not have lightning speed USB - C compliant connector which has the bigger iPad Pro, so the special USB - C cable and 29W power supply wiil lightning does not work with the smaller iPad Pro to load more quickly.

  Return these back to Apple for a full refund.

  Sorry

• Fan of mid-2010 MP in power supply

  The fan in the power supply of my Mac Pro (mid 2010, OS 10.11.5) began its decent slow in death - intermittent squeaking. I hesitate to pay a few hundred dollars to replace the power supply just when a fan $ 20 will most likely do the trick.

  (1) is that someone can confirm that the fan is replaceable? iFixit.com wasn't much help to answer this question, or for parts. Here's their entry: https://www.ifixit.com/Guide/Mac+Pro+First+Generation+Power+Supply+Unit+Replacem ent/32222

  (2) even in the case that does not know the answer to question (1), I want to give it a shot; can someone point me to a source of parts other than ebay.com, galaxyhp.com or Low End Mac google group? I'm happy to install an after-market fan, unless this is not recommended for a reason any.

  (3) any other suggestions? (If the bearing is not tight, I'm curious to know if I can just pack the her with the fat.)

  Thanks in advance!

  I would try a few drops of Marvel mystery oil, he made fans years beyond their phase of freezing/grinding...

• Power supply on the move...

  What link should I plug my USB 2 plug in my power supply for my MBP 13 '' end 2011...

  None of them. The USB ports on your MacBook Pro are not designed to provide a high current to charge a power supply.

  In case you were keen to use it to power your MacBook Pro, you should know that your MacBook Pro will not charge or run a USB power supply.

• Power supply for Powermac MDD

  Hey all,.

  I got a Powermac MDD dead sitting in my room for a few years now that I picked up for free because it lights. I came to the conclusion that it was the power supply, so I took and threw it years. Now, here I am, no power supply and one useless MDD.

  I really want to get this thing to the top and running, but as the price of the power supply on ebay are absolutely ridiculous. I hope that someone here has a job, they are willing to participate with and sell to me. (Pay me for the part + shipping costs). Also interested in an OS disc that will work for the machine, so I can stand him up and running.

  If eBay is too pricing heartburn, try a Mac (MUG) user GFroup in your area. This site will help you locate a:

  http://appleusergroupresources.com/find-a-group/

  As a general rule, you don't have to physically visit the groups for assistance. Several times, simply by sending an e-mail "looking to buy" published groups addresses will receive a response.

  The other option is to look for a private LABEL job and use it for parts. The cost of a scrap computer may be less than the PSU.

• Power supply selection guide

  This MOD can make a post-IT.

  Here is a general guide on how to select a power supply for your HP desktop computer.  The majority of the standard ATX power supply (PSU) must fit in an envelope of HP.  The exception would be a slim casing or the esoteric Merle.

  Looking for a certification 80 + on the PSU to save electricity.  A PC is normally idle or operate at low load 75% of the time.  Therefore, to find a power supply which is more effective in the range 50 - 90W.  A power supply 80 + 350W reaches the level of efficiency of 80% at the exit of 70W (20% of rated output).  The output must be greater than 140W to achieve the same level of efficiency of a PSU of 700W 80 + equivalent.  So choose a power supply that is rated at 25% more than the maximum load of the ACTUAL spending of the rig you will save more of $ on electricity.

  A modern PSU is designed to achieve maximum efficiency between 20 and 80% of the nominal power.  Running a power supply above 80% charge level will result in excessive heat, noise and premature failure.

  A platform Nvidia GeForce GTX 280 (1024 MB of RAM) will rely on 350W max to the wall.  Taking into account the effectiveness of a block of power SUPPLY 80 +, the actual load on the power supply is only 280W (350 x 0.80).  To calculate the required power supply, multiply the actual load by 1.25 (25% margin).  In this case we only need a PSU 350W (280 x 1.25) to run this GPU.

  Let's apply what we know of a rigging of Radeon HD 4870 (512 MB RAM).  290W max to the wall.  Actual load is 290W x 0.80 or 230W.  Now, apply the 25% margin rule and we come to a requirement of 290W PSU (230W x 1.25).  Even if we apply a safety margin of 50%, the power required is always under 350W (230W x 1.50).

  There are no overspec need the power supply by 50%, unless you run your PC up 24/7.  Don't forget that there is a huge variation in the quality of the PSU and side.  Maybe a good 500W PSU is not able to provide as much energy as a quality 350W.  Antec Earthwatts/NeoPower/TruePower and Corsair Seasonic are widely available at several American retailers of quality units.

  High-end power supplies number will need additional power supply PSU in the form of one or two 6/8 pin plug GPU.  You can buy an adapter to convert a molex 4pin to plug 6-pin power of GPUS.

  Hi Nautsj,

  You need to open your PC and measure the physical dimensions of your diet. Here is a list of the things to consider:

  1. technical characteristics
  2. the total power - important
  3. amperage 12 + v - important
  4 modular - is not required, but I like the flexibility
  5. guarantee
  6 i7 and SLI ready
  7. energy efficiency
  8 cost
  9. size - standard ATX PSU is 5.5 "by 5.9" by 3.4 "give or take a few tenths
  10. a single + 12 volt rail is a better choice.

  www.Newegg.com has many choices of power supplies. Corsair, OCZ, Rosewill, Thermaltake...

  The typical EVGA GTX 570 in 9 "long.  The adjacent slot on the PCI-E x 16 slot must be vacant.  Open your PC and do some measures so that you know for sure if the card fits.  According to me, it will fit.

  For what is a PSU, Corsair CX600has very little growth, but the Corsair HX650gives you plenty of space to grow.

  I use the HX650 in two PC.  It is a modular model in order to have better options with the selection of cable.

  "How-to" HP articles should be useful.

  TIP: When installing the power supply, unlock the scanner and slide it forward to facilitate the removal and installation of the new power supply.

• Pavilian A4313W: Power supply for Pavilion A4313W

  Get technical support for my mother. She got an A4313W of Pavilion, which has a default power inside. Which is a specific power supply, or a work of a generic cannot in this system?

  If it's specific, can someone give me the part number for it?

  HERE IS a GENERAL GUIDE for this model of PC.  It seems to be a standard power source, so you can replace it with a generally available device rather than ordering a unit # part.  Don't forget to check the dimensions, however.  Also, IMHO get a higher power than listed unit is only 250w.  I would get at least a 400w unit and they are reasonably priced, too.

• Compaq Mini 110: Polarity of power supply jack

  Hello

  I have a HP/Compaq Mini 110 that was given to me because both the battery and the AC adapter was lost. I have a power supply of the correct voltage (19 VDC) and can get an outlet of the right size. I need to know what the polarity of the plug must be, for example, is the center of the end positive or negative? I also need to know if the computer will be also powered if one battery (even dead) is not installed. If it will power-up with the polarity a/c adapter, I'm going to buy a battery, otherwise I don't lose money. Shame on HP/Compaq to not show a pictorial of polarity on the camera body. If I can get going, have enough moxie upgrade to Windows 10? Thank you.

  Here is the Service Manual:

  See p. 54 on the hard drive. She straight plug the motherboard, but it shows a cart or make sledding which does not move there and the SSD is welded to a SATA connector. For some time I took one of these apart.

  He's a regular SATA and the size limit, it's what is on the market, not the hardware, so you could theoretically install a 2 TB or a 2.5 inch SATA SSD. You could probably get one inch 80 gig SATA SSD 2.5 for a pittance and it would run as well as he is capable of running.

  The memory you have is DDR2-800, but the system he clocks up to speed DDR2-533.

  The power Jack is soldered to the motherboard and there is no way I know to stretch upward. A lot of youtube videos on the welding on a new jack and you can find the plug for a few dollars. It is not a work that I do, but I saw several times and I think you can probably manage it if you have the soldering equipment.

• Power supply for a1648x?

  Hi all. I wanted to get a new graphics card for a while now, and I finally decided to get the GeForce 8500GT 1 GB. The problem is that the minimum power is 350w. On the specs of my computer, it is not the power supply. My computer is HP Pavilion a1648x. I'm pretty new to this, so if someone could explain where I can find the power supply or what to do if I don't have enough power, that would be great. Thank you.

  You currently have a POWER ATX 300w PSU. (REF: 5188-2625).  If you want to upgrade, simply buy a 24-pin ATX PSU that meets the minimum requirements for your graphics card.
  
  I would recommend a PSU Antec from Newegg.

• HP ENVY PHOENIX CTO 810-135QE - 600 watts power supply Question

  In the near future, I would like to upgrade the video card in my desktop HP ENVY PHOENIX CTO 135QE-810 GT 640 default to something a little more powerful and I was wondering if there is any details about the default 600 watts power that will help me in my decision to the next video card.

  I know that some video cards require a number of amps on the 12 volt rail and all the information that I have found previously on the power of 600 watts power supply in the computer is not in that kind of detail.

  What I read, the power is a Petrus 600W e-star 5.0 Bronze, HP Part number 633186-002.

  Any additional details and details on this power to help me determine the next video card would be useful.

  On a side note the video card, I'm currently doing is one of the next Nvidia GTX 750 TI models, thoughts and recommendations on this specific map?

  Thank you

  Hello

  Your PC has UEFI bios, so most video cards should work.  Some video cards will work in UEFI mode and others in legacy mode, that your PC is able to run.

  When the manufacturer of the video card and/or AMD or NVIDIA specify a minimum power supply size then it is best to stick to this recommendation.  Not all power supplies are built to the same standards of quality.  In addition the internal components, temperature, charges unknown and time that the PC will be placed under the maximum load are taken into account at the recommendation of minimum power supply is indicated.

  I have not seen a power of 500 watts with 12v rating of 18A, but this does not mean that there is not. And if that's the case, then the total power rating is suspect. A video card that requires an external auxiliary power connector will also draw power from the PCI-E slot.

  Are there cases where the minimum size of the power supply is insufficient? Yes, those who might be extreme but someone can have connected to power different connectors either to avoid buying a new power supply or maybe around just the food manufacturer minimum power rating. Some may do it thinking 'I'm going on fox the Fox ". It can work, but maybe the questions later start occurred.  I prefer to get the job done right the first time. You don't need a power supply to perhaps of overload and short circuit then internally causing spikes to the components in the PC.
