Optiplex gx820 can i connect 300 watt power supply


You listed GX820 and GX260.

I am assuming you meant the GX260.

There are three varieties of the Gx260.

1) The SFF (Small Form Factor) power supplies can be replaced, but I know of no upgrades for these.

2) For the SDT (Small Desk Top), you can get up to a 270 (best I have seen).

Example of where to get one.

For the Mini Tower, here is an example of a 400W replacement. There may be others for this model.

I have a GX280 Mini Tower and recently upgraded my PSU to one very similar to the one above.

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.

Addboat,
I have wasted enough time in Dell community for exactly the same problem. Even a link mentioned by Move_n_man above, on 8 Oct. 09 refers to my posting in Dell community. Its nothing but a crashed bios and unfortunately theres none who could tell how to flush the bios and reload fresh bios in the bios chip when computer does not boot.
Dell is in no mood to help! So do the so called experts of the Dell community.

Installing a sound card into my Optiplex GX260


Hi

OptiPlex GX260 can be Small Form-Factor, Small Desktop or Small Mini-Tower. Compatibility with PCline 5.1 PCI depends on the profile of the PCI Card and the Profile of your OptiPlex.

GX260 Small Form-Factor is compatible with Low-Profile PCI Cards only. GX260 Small Desktop and Small Mini-Tower are compatible with standard PCI Cards. (Small Mini-Tower however uses a PCI Cage).

Check OptiPlex GX260 Systems User's Guide - http://support.euro.dell.com/support/edocs/systems/opgx260/en/ug/index.htm
From here you visualize the 3 form factors. Also there is info and steps to install PCI cards.

NB:
1. Generally, upmarket PCI cards are standard height. Some manufactures supply a metal piece to allow it to be used in Low-Profile or Standard Profile.
2. Driver software needs to be installed after the hardware is installed.
