Help, will HD5450 1GB DDR3 work on a 250w PSU?

Good evening, I'm a bit confusing for a videocard that can run well on my PC. I want to buy a videocard to increase performance on HD videos, cinema, etc and maybe a bit for old video games.

I understand the main things to have in mind is board compatibility and needed PSU. My PC is 4 years old and it has and ACER 946GZT-AM V.1.0 motherboard, comes with PCI-e 1.1 which I believe PCI-e 2.0 cards are compatible.

The rest are:
-Core 2 Duo E4400 @ 2,00 Ghz
-1x2 GB Markvision RAM
-Delta Electronics DPS-250AB 250W

I put an eye for the ati HD5450 or nvidia gt210, which I like for the cheap price and well performance for cinema, any other upper than these require more than 350W I think.

I research on forums and some says that HD5450 can perform well on a 250W PSU, others says at least 300W is needed.

Please I beg for help here, any suggestions is appreciated, if I should change the Power supply I will do it, but I want to know if I won't have problems with this HD5450 on this board.

here's the PSU label: http://oi48.tinypic.com/11hbc3r.jpg

Thanks.

Edit: I decided to buy a >500 W PSU, if there's a chance to go for an upper videocard, which will be good? Gt430? Gt220?

  1. Hey,

    Well as @ct1615 said your psu should be fine, and I noticed you decided to get a bigger one, and that does indeed open up some doors to what you can get. What is your budget for getting a graphics card?
  2. I strongly recommend a better psu, I agree delta does make some ok power supplies but they usually outsource them to other companies instead of using them themselves.

    That power supply is only capable of 180w at max load I surely wouldn't put any graphics card in that without first upgrading.

    Edit: derp, I thought you had a 95w cpu instead of 65. Still a better idea to get a better quality psu.
  3. hey itll run comfortably ive run a hd 5450 before on a generic 250 w without any issues

    i don't even know where to begin in correcting all that crap :pfff:



    The first sentence is mainly opinion, I sure as heck wouldn't put any psu in my system that was branded as a delta unit, without a glowing review behind it.

    during a stress test you won't break 165w with a more power hungry system.

    Core i7 Test System Specs
    - Intel Core i7 965 Extreme Edition (Overclocked @ 3.70GHz)
    - x3 2GB G.Skill DDR3 PC3-12800 (CAS 9-9-9-24)
    - Asus P6T Deluxe (Intel X58)
    - Seagate 500GB 7200-RPM (Serial ATA300)



    let's see what guru 3D said

    Our test system is a power hungry Core i7 965 / X58 based and overclocked to 3.75 GHz. Next to that we have energy saving functions disabled for this motherboard and processor (to ensure consistent benchmark results).

    Our motherboard also allows adding power phases for stability, which we enabled as well. I'd say on average we are using roughly 50 to 100 Watts more than a standard PC due to these settings and then add the CPU overclock, water-cooling, additional cold cathode lights etc.

    Keep that in mind. Our normal system power consumption is much higher than your average system.


    Single GPU 5450:

    System in IDLE = 154 Watts
    System with GPU in FULL Stress =177 Watts
    Difference (GPU load) =23 Watt

    and finally techppower up states you will use 9w for video playback and a mind blowing 13w during gaming. i can't imagine they make PSU powerful enough to run two of these bad boys in CF...



  6. ^ ohh, I thought the card took at least 30-50w.(Even then it wouldn't be an issue) Thanks for taking the time and posting the charts :)

    Regardless OP I was wrong, go for it.
  7. Look at a 6450 512 MB DDR3

    http://www.newegg.com/Product/Product.aspx?Item=N82E16814125378

    20 dollars and has much better performance in old games.

    delta made PSU for DELL for a while, those PSU were well known for providing "good" power for a mass vendor PC.

    they currently make the well reviewed antec earthwatt series and antec High Current gamer Series (750w+, below is seasonic), among other brands & series


    I wasn't aware they made dell psus, though I am using their Antec EA 500D in my current system, its a pretty alright power supply.
  9. Yes, it will run. But dont expect performance out of the HD 5450. I bought a PC with it and even minecraft couldnt run well
