Question about Dell (HP-L161NF3P) (P0813) 160-Watt Power Supply

Dell GX270 SFF 160Watt PSU - no start at low temperatures

Hi,
my Dell GX270 SFF often does not start at the first time especially on a cold day.
The problem seems to be the powersupply. I have temporary used the PSU from an other machine and it works.
So I think the PSU is worn out. Is there a possibility to replace the capacitors or other error-pregnant parts?
The machine is 4 years old now and out of guarantee.

You're on the right track... failing capacitors were a real issue for these Dell PCs (and others), in fact I would be surprised if there wasn't at least one failing capacitor on the motherboard as well.

Not an extremely difficult task though it requires some electronics skill, suitable equipment & appropriate replacement components, try brands like (but not limited to) Rubycon, Panasonic, Sanyo & SamXon you're looking for Low ESR rated capacitors of equal voltage rating & capacitance.

Additionally 10v capacitors can be replaced by 6.3v items as you're only looking at 12v, 3.3v & 5v being produced within the PSU.

    I should also point out to use extreme caution when dealing with the internals of any such device as the large capacitors can store lethal charges of electricity... allow the PSU sufficient time to discharge.

What usually breaks down in a switching power supply ?


I'd guess it was (an) electrolytic capacitors ?, especially if PSU is old or has been subjected to high temperatures. Perhaps an internet search would tell you more ?

I am looking for a schematic for a Dell Optiplex GX280 power supply. The supply is model HP-U2106F3.


I just replaced my GX280 power supply (mini-tower) with the following 400W for $30.

The only place I can think you will find an actual schematic for the PSU is from the manufacturer.

My dell gx270 power supply has been burnt how can i repair it


If the power supply has been burnt, individual electronic components likely failed due to a power surge or other issue, and you may have experienced a short within the unit. Unfortunately, due to advanced difficulty and low cost, power supplies generally are not repaired, they are replaced instead.

Can you turn on an ATX power supply when not connected to a mother board?


Yes, especially if you are testing the PSU connections with a tester. Just plug the PSU into a wall socket, it does not have to have its connections connected on the motherboard for it to be running.

Dell power supply NPS-210AB will not turn on


Try switching it with one that you are certain works just to make sure it didnt blow or that your computer is working alright. or, using a multimeter, try and check for any current flowing to any of the connectors...

I have a Dell Desktop Optiplex GX270 the problem which i am facing is that its totally all right when i start it but after few minutes it seems that its hibernating the display is gone just blinking of LED...


Here's the bad news.
Dell had the 270 and several previous models made for them and the manufacturer installed cheap capacitors on the motherboards to save money. If your machine is still under warranty Dell will replace the motherboard. If not, they will sell you a refurbished one if they still have any. If you are handy with a good soldering iron, look at the motherboard and find the aluminum capacitors that show bulging or leaking from the top or bottom. Replace them with caps of identical value and higher quality.
Otherwise, follow the good news.
The good news is, Dell makes many more computers for you to choose from and purchase, and the capacitor problem has been resolved.

Yeah. I know.

Want to upgrade power supply on Dell Dimension 4700. Bought Rocket Fish RF-550wps 550 watt powersupply to install . Unable to proceede no schematics ror placing wireing


Hi there.
Rocket Fish RF-550wps PSU is standard ATX power supply.
Dell tend to use their own power supplies which differ slightly from standard power supplies.
I suggest you take or send the Rocket Fish RF-550wps PSU back as it won't fit and order one from Dell themselves, at least then you will have a guaranteed fit.
Once you have your new power supply from Dell (or a Dell ATX power supply) it should be easy to fit in.
Post back if you need any more help.

Good luck and thanks for using FixYa!!

HP Pavilion 250 watt PSU that includes a Nvidia GeForce 9300


The maximum output of a PSU simply means it is able to supply a certain amount of power. It can also deliver anything under the wattage. Where you fry things is where the connectors are wrong. HP, COmpaq, Dell, IBM have all, at times, used nonstandard connectors in their PCs. If you take something with a standard connector, and use it in a machine where that connector needs to nonstandard, you can fry stuff.
