Studio 540 - Replacing PSU?

This question is answered

I will soon be replacing the PSU in my Dell Studio Desktop 540 and was after advice from those who have done it before.

I intend to replace the Dell 350W PSU with a Corsair VX 550W ATX PSU - can anybody confirm that I will be able to physically fit this PSU and that it will work without problems? This Corsair PSU is "Standard ATX PS/2 size" and "supports the latest ATX12V v2.2 standard and is backwards compatible with ATX12V 2.01 systems", if that helps.

I have also read conflicting things about Dell desktops and PSUs - one forum said I need a specialist adapter to "convert a 20 pin atx connector to Dell proprietary 20 pin connector" and provide a "Dell P10 connector"(?), while others have said replacing any Dell stock PSU with another brand can damage the motherboard. Some clarification would be greatly appreciated.

Furthermore, is there any more general, helpful advice for someone who is replacing their PSU for the first time? Obviously I don't want to screw this up and fry my computer! How difficult is it to do as a first-timer?

    That refers to old legacy Dell desktops with 20-pin power connector motherboards, that used Dell proprierary power supplies.

    Dell Dimension systems, 2200,2300,4300,4400,4500, 8200, and above, the power supplies [20-pin] are standard ATX, that have been modified, by having the power on-off switch removed.

    Dimension 4700, 8400 systems and above, use standard ATX [24-pin or 20+4-pin motherboard power connector] power supplies.

    Dell's small format, the D-8100 and several XPS systems, use a proprietary power supply.

     The Studio 540 Mini Tower is not one of  them, plus it has a 24-pin main motherboard power connector.

     Studio 540 Mini Tower systems can use most generic standard ATX power supply units, with either a 24-pin or 20+4-pin main motherboard power connector, with or without the on/off switch and four SATA power connectors.

    The Corsair VX 550W ATX Power Supply (CMPSU-550VXUK) [CMPSU-550VXUK] you gave the link to, should be compatible with the Studio 540 MT, but you may have a small problem finding space for the excess cables.

  • Just an update to my original post - I successfully installed a Corsair HX 620W Modular PSU into the Studio 540 Mini-Tower earlier today, and it runs perfectly. Here's a photo, you can see the original Dell 350W PSU removed in the top left:

    The Studio 540 MT does not use a Dell proprietary power supply, this PC can use most generic standard ATX power supply units, with either a 24-pin or 20+4-pin main motherboard power connector, with or without the on/off switch.

    You should be able to buy a compatible power supply from either a local or online computer store.

    Note: You require a power supply with four SATA power connectors.

    The link you posted does not show any power supplies, only computer cases.

  • Hi

    I've just found your post after I posted a request for help in installing the same Corsair in a Studio XPS 7100.

    I take it that either of the four-pin plugs on the hard wired EPS12V cable attach to the motherboard (can't see from your photo if you have two seperate plugs). Given the length of the Corsair, how did you overcome the two protruding flanges at the top of the case?

    Sorry, I don't know of any procedure to change the speed of a power supply's fan.
     
    Suggest you contact Coolermaster's Technical Support about the issue.
