Hi, i'm in need to upgrade my 200w power supply on my Dell Dimension 8100. I came across one for my machine on ebay but the person told me it won't work because my own PSU does not have a ATX 24 pin and an 16 pin connector which both are meant to connect to the motherboard.

Every time my PC starts up the PSU is very loud. I came across another one on this site   http://www.atxpowersupplies.com/400-watt-power-supply-FSP400-60PFB-M.php  and it says clearly its for a Dimension 8100 but still has the ATX 24 pin and an 16 pin connector. Would it be safe to me to purchase this without it frying my motherboard?

My specs are:
Dell Dimension 8100
640mb RDRAM
Geforce 5200 256mb Graphics CardSome Dells use non-standard power supplies.  Read the nameplate on your 200W and see if it's the same as the so-called 400W.
Output     Max. Load
+5Vsb    2.5A
-12V    0.5A
-5V1    0.3A
+12V1    16A
+12V2    16A
+5V      20A
+3.3V    20AHi Computer_Commando, sorry only getting back to you now. Just CHECKED with my PSU and it does have a 24-pin ATX and also 1 x 16-pin Connector but i can't seem to find if it has a 4 Pin Molex P4 Connector square plug that connects direct to the motherboard.

My PSU is a 250w i thought it was a 200w. The details on the nameplate are:
Input 100 - 120v /6.0A
         200 - 240 /3.0A

Output +5v /28.0A
            +12v /14.0A
            +5VSB /2.0A



I also came across one 330w PSU on ebay. Would this be the right one to buy in your opinion?   http://cgi.ebay.ie/Dell-Dimension-8100-330W-PSU-NPS-330CB-024RGY-24RGY-/220548246093?pt=UK_Computing_PowerSupplies_EHIt seems to be the right one, it does say Dell on the nameplate in the pic.  BTW, it's that 16-pin motherboard connector that makes the PSU non-standard.  It's possible the 16-pin takes the place of the 4-pin Molex P4.Thanks Computer_Commando for your help. I'm going to buy that one soon on Ebay. Quote from: louis76 on August 28, 2010, 08:07:02 AM
