Powerbank Compatibility (Replacement Power Supply)

Q: Powerbank Compatibility (Replacement Power Supply)


I am planning on buying a portable wall charger/powerbank and I just want to make sure it won't reduce my phone's battery life in the long run. The phone I have is a BLU Energy XL, which came with a 9V/2A charger that plugs into the wall. However, the powerbank that I am most interested in provides 5V/4.8 or 5V/3.0A (or Qualcomm 3.0, which I am actually not sure about the tech specs) and most powerbanks in general I believe provide something like 5V maximum from USB type ports. In looking up some articles, I discovered that one should try to match the voltage of a replacement power supply (in this case, analogous to my powerbank) to the original power supply because otherwise this may impact the battery's lifetime. Is that true?

In general for my knowledge, how does one convert between something like 9V/2A and 5V/3A in terms of the impact it has on a battery? I can kind of conceptually understand the impact that current has in that it really sets an upper limit for the Amps that a power supply can find and the higher the amps for a given voltage, the faster a device will charge. Not really sure about the impact of voltage? Can one just compare the power of the different chargers like 9*2= 16 watts vs 5*3=15 watts?

Thanks in advance!!

Possibly a noob question, but please help if you know about this.

When buying a PSU I know I need the right Wattage for compatibility with my components. But is it important (or not) to also know the Amps and Volts and/or size the cables have that will go into the MOBO? Does this have anything to do with ATX/EPS? If so, what is ATX/EPS? I am cluless, please help me understand WHAT is important to know and what isn't. Thank you

A:Power Supply - Compatibility

Voltages are standard. Amps matter but mostly on the +12 volt rail(s), that's where most components draw from. Any quality power supply will have the majority of its power on the +12volt rails.

EPS is an extension of ATX adding extra power, stability, and connectors for higher end systems, they can be used in place of regular ATX power supplies. I think most good ones these days are EPS.

The maker of the PSU as well as how many watts are the two biggest factors when buying a PSU. If you read through a lot of the post in this forum, you'll find that many of the problems are PSU related, and that these problems are extremely hard to diagnose.

Hi I have a Dell T5400 with flashing 1 and 3 lights. I tried multiple different combinations of ram and nothing works, so I suspect the power supply is faulty. I bought an inexpensive one on ebay to hopefully exchange the PSU but as luck would have it the model number on the PSU is different. My broken one is H875E-00 and the new one is N875E-00.  The motherboard looks the same but they have different REV numbers. Are they compatible? Guess I know what the reply is going to be ...

Hey guys,

My motherboard has recently blown and I've had to replace it. My only issue is that it has a different internal power source to my former motherboard and I'm not sure if I can utilise my old power supply with it. I've included pictures of the motherboard connection (the blue one) and the power supply connection. Power supply connection is for a larger connection but it works perfectly with the motherboard, except it is inserted into 4 slots rather than 8.

Is this safe? It seems to be working fine.

A:XPS 410 Power supply replacement

You can run any retail ATX power supply in the 410. I would recommend getting a modular PSU so that you only connect the wires that you need and put the others away until they are needed. This will help with not getting a clutter of wires that block the air flow.

Recently the fan on my 600 W Cooler Master Power supply started to make increasingly loud noises. Upon investigation I found that the fan was locking up and then fighting to spin. I tried dusting down the system but had no luck in getting the fan to function properly. So yesterday I went out and purchased a new 650 W Antec Power Supply to replace it. I powered down my system, shut off the power supply, and removed the power cable. With an ESD strap tethered I documented the connections, removed the cables, and replaced the Cooler Master with the new Antec PSU. I then powered the box back up heard it post, figured it was fine and put my monitor back on it.

This is where my problems begins.

My system configuration is as follows:

motherboard: nforce 6801 sli
vid card: 8800 GTS
HD: two 76GB raptors in a RAID 0 for my OS
HD: two 500GB 7500k drives in a RAID 0 for storage
PSU: 650 W Antec
OS: Windows XP

When I power the box up all fans are active, the hard drives spin up, the mother board posts normally, and displays the "FF" status on the motherboards LED indicator signaling a normal boot process. The BIOS runs and I see it detect my two RAID stripes and it indicates that they are healthy. It gets to the boot from CD check and goes to a blank screen. It does not progress any further.

I am not of the opinion that the old PSU somehow damaged some system components as the actual power output was fine and my system functio... Read more

The only thing I can think of is you maybe unseated something a bit when reconnecting stuff. With the power off of course go through and reseat all the power connections, data cables, and add-on cards.

Any reason you didn't just replace the fan in the PSU rather than the entire PSU? Maybe put the old one back in temporarly just to see if it works still.

IMO, 40GB is way too small for the system drive. You'd be constantly babysitting it, moving files, and everything you do would have to be retargeted before starting a project. Windows 7 64 bit would use half of that space just for itself.

if i install a 400W PSU will it effect the other components in any way, eg... blow the motherboard? fry the HDD?

searched already for an answer but could find a specify yes or no... cheers guys

A:Power supply and mother board compatibility

Most likely no. There are some older Dell systems that had a proprietary power supply where the pins were switched around so that only a Dell PSU could be used.

As far as pure wattage goes, have no fear. 1000w power supplies are just as safe if not safer than that 200w in the current system.

Really, if your planning on investing in such a nice graphics card, you might as well put just a little more into the PSU as well, maybe a 450w or 500w.

Hello, I have replaced the power supply on a Gateway PC. The PC starts to boot then hangs with the message "no response from MSD". I think I may not have re-connected all the devices properly, or, not plugged in the power to somewhere. Rather than start troubleshooting I thought someone here might know that specific error code so I can go directly to the problem. Any help? Thanks.

A:Gateway Power Supply replacement

Sounds like there is no signal from the video card. How far along in the POST does it get? I am also not sure if Gateway uses standard ATX power supplys, you may need to get one directly from Gateway. Compare the pinouts from the old PSU and the one you just put in and see if the voltages are all the same with the same number of pins. This would be the connector that clips onto the motherboard.

For and HP Computer. The power supply model is a Hipro HP-2537F3R and is 250W. I thought that just any ATX power supply would work but i talked to a local vendor and he told me that I have to find one that is specifically made for HP or Compaq Computers because of some kind of difference in Wiring. Is This true? He can get me one at a decent price, but its gonna take him about a week and i was hoping to get one sooner. So i wanted to see if there was anything compatable that i can get locally. Thanks.

HP uses a small form factor psu as in all the ones I have replaced. They are ATX psu's but to get them to fit your case you may want to wait on the other guy as in if it does not work you can return it on their business for getting you the wrong part and not be stuck with something you can't use.

I had some intermittent shut downs before the power supply finally totally crapped out. I have an HP Pavillion. I first bought a 750 watt supply from Tiger direct, but it wouldn't fit in my case. BUT, I did hook it up and make sure that the computer started up and ran ok. It ran fine. NOW, to replace that, the only thing I could find that would fit was a 350W diablotek. My problem is this, Now, when I hit the power button, the power supply fan turns on, but nothing else. When I turn it off, a power surge spins the cooling fan and the cpu fan.
The side note would be that when I was putting in the power supply, the heat sinc was in the way. When I pulled it out, I didn't realize that the cpu came out with it. I jacked up the cpu when reinstalling the sinc. I bent some prongs. I have replaced it with the identical cpu and still have this problem. Any ideas??

I'm getting a GeForce 8400 gs, and a 380W power supply.

The graphics card says "Minimum recommended power supply with +12 Volt current rating of 18 Amp Amps." I looked over the power supply specs, and none of the 12v outputs have an amp rating of 18. I read somewhere though that you have to combine the rails to add up to the amp rating? I assume that's for high end graphics cards, where you have to plug the psu directly into the card. I don't know what a rail is, I don't know how it would work for this graphics card, since it doesn't seem to require the psu to plug into it directly, Iz confoosed.

I am basically clueless when it comes to power supplies, so can someone please educate me in this, and PLEASE be mindful of how you explain it because like I said, I'm almost clueless about this stuff. Taking a couple more minutes to throughly explain this to me so I understand it well, won't kill you.

I don't want to sound rude when I say this, but it annoys me when people do this to me. I honestly don't care what graphics card or power supply you have, if it's better than mine and you think I should get it. I am well aware that there are graphics cards, and power supplies, that are WAY better than the ones I chose. I chose these pieces of hardware because of my budget.

A:Question about power supply compatibility with graphics card

It may be the way the specs are written on your PS... but
The graphics card does care what the output is... more than the motherboard or other component does...
A cheap power supply from 2005 or before had a better chance of not supplying the minimum power.... Now you can see all these specs for a quality power supply when you look at the descriptive information on the power supply section of Newegg, Directron, ZipZoomFly, cdw.com, and many others... but only in the past year or two has it all been published.

I have an ASUS M4AGTD PRO, and it requires EATX power.
However, my power supply only has ATX and EPS power (Both 12v, as required by my motherboard).

I at first tried using the EPS cable, which worked. Sorta.
It wouldn't boot, but I can't exactly say that it was at the fault of the PSU just yet, as I had incompatible RAM (wasn't listed under the QVL) and CPU (wasn't listed under the supported processors), both of which are being replaced shortly.

It fit perfectly into place, as well. Which I can't exactly say for the other cable....

The ATX cable didn't work, but it's possible that I didn't place the 2x2 pins in their correct positions, as I've heard mention that it's still possible to power the motherboard with ATX when it requires EATX.

I'm troubleshooting several other things on my new build, so I can't exactly limit my issue to my power supply.

But I guess what I'm asking is whether or not my PSU is compatible with my motherboard.

If it is, then I can eliminate it from my list of suspects.

I chose this motherboard because of its cheap price for what you get with the graphics card for now, and being able to add a pci-e 16x 2.0 card on later.

The mobo is micro atx and says power pin 24 pin.
When choosing the case will anything that says ATX be fine?
Since micro atx is just atx but smaller?

Since the motherboard says 24 power pin the case MUST say it has a 20+4 power supply unit?

Some cases with a power supply do not say how many pin the psu is at all. Do I assume those are just 20 pin?

Laptop spec: HP530, Model HSTNN-C29CCeleron 1.73ghz1.5gig Ram,Windows Vista Home Basic. Last year I started having trouble with my HP530's power supply.

I created a topic not long ago about my power supply getting ready to die on me. I thought I would get as much out of it as I could but I went ahead and replaced it with OEM Dell power supply 350W a few days ago. It wasn't hard to swap out the old one and put the new one in but trying to get the CMOS battery out was a chore unto itself. I took a picture of the inside configuration and wrote down where everything was connected so I would get it all back together right. When I got the everything hooked back up and plugged it back in to start it up I got an amber light on the power button. It turned on anyway and when it did I got the infamous "Diskette Drive 0 failure" screen. That's not a big deal and I fixed that in the BIOS controls. I also had to reset the date and time. Here's where it's getting tricky. I can't get either optical drive to read anything. Before they were working fine. The system does recognize both the DVD ROM and the DVD RW drive and says they are both working fine. When I put a disk in they start spinning normally but the Windows dialog box asking me what I want to do never comes up. I tried to do a systems restore and got the dreaded "An error has prevented windows restore from working" box with the red X. I wonder if something is wrong with the registry? I know I have both the optical drives connected right. One is plugged into SATA 1 and the other into SATA 4, just like they were before. I can't figure ... Read more

I replaced a busted power supply in my old XPS 420 (with a MasterCool MasterLite 600). Everything has seemingly gone wonderfully. However, during the replacement I had to remove the heat sink from the CPU to get to the cables. I've never really installed heat sinks before so I got some thermal paste a put a dot tried to put the heat sink back on and it didn't fall into place. When I removed the heat sink I noticed the paste hadn't covered all the CPU so I added a bit more to make sure. Then was successful the next time putting everything into place.
I'm really concerned I might have not done it correctly so I installed speedfan to check temperatures. For the CPU I'm getting temperatures of 80degC (just posting this post). Which seems high, but I remember checking speedfan a while back and have a faint recollection of the temperatures also seeming high before. Also the GPU is at a similar temperature and I didn't touch that.
I'm just wondering should I pull the heat sink off and do the thermal paste again or is this a non-issue and these computers just run that hot normally?

I would redo the heatsink application, with Arctic Silver thermal compound.  Fully clean off the old thermal compound from both the top of the CPU and the bottom of the heat sink.

Hi, I am new here
Anyways, I have got this Dell Inspiron 660s which has power supply blown and I am thinking to buy a modular power supply (I am aware it might not fit inside the box). I am also thinking I may add a graphic card to make it a gaming or video editing station. (Haven't decided any specific graphic card tho). 
My questions are,
1) Is it possible (and/or recommended) to use modular power supply for this pc?
2) If yes, how can I choose and what are the key factors should I consider while buying a modular psu? 
Model name  L220NS-00
Printed information on PSU:


+5 V ~/15 A
+3.3 V ~/10 A
+12 V ~/18 A
~+5Vaux ~/3 A
+5 V & 3.3 V SHALL NOT EXCEED 100W
