HD 7750 300w psu

I have a inspiron 580 with 300 watt psu, can i put in a hd 7750 even if my psu is onlt 300w? It claims you need 400w minumum and my computer came with geforce 310 which has a max of 30 watts, the 7750 is said to have max 42 watts. Will the 7750 work?


Sorry I made another post similiar to this...

  1. You should be OK with the 7750... an extra 10-15W of power shouldn't cause that PSU to explode. That said, if you can upgrade your power supply, it's always worth it to not run a generic crap-o brand 200-350W unit.
  2. There are two versions of the Radeon HD 7750:

    Radeon HD 7750 900 MHz Edition
    • Maximum Board Power: 83 Watts
    • PCI-E Supplementary Power Connectors: One 6-pin

    Original Radeon HD 7750 800 MHz Edition
    • Maximum Board Power: 75 Watts
    • PCI-E Supplementary Power Connectors: None

    Ok, so its not necessary to upgrade my psu, i get that. but if i do upgrade my psu, what should i upgrade it to? (I have a low budget so dont go too high with the prices)

    Also, i have heard that you cant upgrade the dell psu to more than 400w, and i have also heard that you cant upgrade the psu at all... Is that true?

    I dont know a great deal about computer hardware so any help is greatly appreciated
  4. As long as you have an ATX case, you should be OK upgrading to most any power supply, to the best of my knowledge.

    On a budget, this:

    Thx for the reply, but can you show me where it states the power usage of the card?

    Also i would like to get this version of the card: http://www.newegg.com/Product/Product.aspx?Item=N82E16814121633

    what is the max power it draws and does this require a 6 pin connector? Also it is pci express 3.0, will this work in my stock dell inspiron 580 motherboards pci e x16 socket?

    I made a slight mistake, the 7750 takes 55 watts (http://www.hwcompare.com/11774/radeon-hd-6770-1gb-vs-radeon-hd-7750/)
    and on amd website is says max is 61 watts

    Im not going to risk it so i guess im going to upgrade my power supply. Thanks i really appreciate your help, i dont really have experience with psu's so this may sound like a stupid question; does the psu you suggested have the sufficient cables to plug in my dell hardware to the psu? So if i install it i just screw it in my stock case and connect the 20 + 4 pin connectors?

    The ASUS HD7750-1GD5 has the following measured power consumption (from http://www.techpowerup.com/reviews/ASUS/HD_7750/24.html ):

    Furmark: 43 Watts
    Gaming: 43 Watts
    Blu-ray Playback: 22 Watts
    Connected to two monitors: 15 Watts
    Idle: 5 Watts

    This card does not have or need a 6-pin PCI Express supplementary power connector.

    The Dell Inspiron 580's 300 Watt OEM PSU, with its combined +12 Volt continuous current rating of 18 Amps should be able to power your system with a single ASUS HD7750-1GD5-V2.

    Your Dell Inspiron 580's motherboard has a PCIe 2.0 x16 slot. A PCIe 3.0 graphics card should be fully backward compatible with the PCIe 2.0 x16 slot on your motherboard.
