XPS 420 change power supply

againsmile,

Yours is the first report of anyone doing this to the XPS 420.

Hi~ PS still works well. I'm watching movie now. You can find this PS at newegg. http://www.newegg.com/Product/Product.aspx?Item=N82E16817152028 When I install this PS, the one thing I have to think about is the size. The size between the original one and this one is different. The height of this one is small.( I think the PS of dell is big. ) So, there is a little space. I uesd screws and I can fix it. (Still, thers is a space behind of the computer) If there is any problem with this one, I'll post it. Thanks,

Can only echo what Chris said you really are the 1st one who has reported changing it on the entire interweb!!

Post back exactly what happens when you push the power button. I mean exactly.

Could you also post a link to the PSU on a eshop or manufacturers website never heard of a power supply with that name.

When you changed it over, everything should have just worked, make sure you plugged in smaller 4 & 6 pin connectors properly. I have not received my 420 yet, its arriving at the start of the week so will get a chance to fiddle about with it then and see whats what.

Hey dell/CHRIS i have a XPS 420 with a 375watt..can i buy a 425watt from dell to replace the 375??if not i can just get a standard ATX power supply..looks like it worked for Againsmiles...please let me know than you

grprixgt97,

Currently no. Since againsmile got that one working, go with it. Of course, Dell will only support the hardware we shipped.

hi thanx for the quick response..ok now i feel kinda retarted..another question..i looked  at the power supply and the only thing i saw where it would say what the wattage was..it says output 425w..so i take it i have the 425watt..it doesnt say 375watt anywhere on the power supply..maybe i got lucky and got the 425 power supply..is there anyway to tell or to check..so i know for sure...again thank you for your time..please let me know.....thank you

COOL...then i can get a NVIDIA 8800 GT VIDEO CARD..AND THE POWER SUPPLY WILL HAVE THE 6PIN POWER CONNECTION FOR IT..SINCE ITS THE 425W...

grprixgt97,

You have the 425w.

it would have it if it was a 375W..

cool..one thing i am noticing from the 425 power supply..is a high pitch noise..i opened the case and stuck my ear up to the power supply and thats where the high pitch noise is coming from..its really starting to bug me..is there a way to replace it with out sending my whole system in for repair...will DELL send me the power supply in the mail and i can replace it my self>????i looked around in the forums and see other people are having the same problem with the 420watt power supplys with the high pitch noise...please let me know..

if you are under warrenty then yes they will send you one. or if you have onsite you can get a tech to do it. Just contact support tell them your issues and politely demand a new supply..

thanks for the info..yeah i talked to a rep today and they are sending me a new POWER SUPPLY...I rather install it myself......thanks for the info

Its a reset switch instead of blowing a fuse this goes and you push the button to get going again.

well i recieved my 425watt replacment today..swapped out the power supplys...the new power supply that dell sent me does the same thing..makes a HIGH PITCH SOUND..so i take it..it must be the model /brand of power supply...well i guess my only luck is to buy my own from a store and take my chances.....sheesh i love this computer but the noise is driving me crazy...

what does the little gray botton do on the back of the power supply
