  • Power Supply sufficient?

    It is very hard to find if you have a powerful enough PSU to power your computer so I'm asking the tech heads here if mine is powerful enough for my components.

    My system:
    Asus p5q motherboard
    Evga geforce gtx 260
    Seagate barricude 500GB drive
    Western Digital 250 GB drive
    DVD read only drive
    Logitech G15
    Soundblast audigy 4
    4 GB's 800 Mhz ram.
    E2180 CPU soon to be an e8x00 or q8x00
    2 internal fans mounted.

    Power Supply is an OCZ 500W Stealth Stream.

    Am I ok with that PSU? My power readings are correct according to Asus Probe as well.

    I ask this because i recently noticed my dvd drive giving me problems with read speeds and causing my mouse pointer to lag as well as dvd video's not playing at full capacity. I ran Nero disc speed and it could not test a DVD all the way through but it did test a plain CD at very poor speeds. It's an LG 52x DVD Drive HL-DT-ST DVD-ROM GDR8163B.

    Thanks for any help.

    Re: Power Supply sufficient?

    It should be more than enough.

    Just make sure your +12V line(s) supply at least 32 amps or so. (Formula: 500 / 12 = 41.67 A) < That's the basic formula, of course your PSU might not give 41 A and it miay give slightly lower or higher depending on what it's rated peak wattage is.

    Edit: Looked on OCZ's site and found your PSU's label: OCZ 500W Stealthxstream PSU.

    Your PSU should be able to supply up to 40 A on the +12V rails which means, it's more than enough power for your rig (which I'm guessing uses maybe 28 A during heavy gaming/multitasking - basing off of peak load from a PSU amperage/wattage calculator).

      If it's an IDE DVD drive, check the IDE bus speed settings. It may be running in PIO mode or some setting that's really slow.

          eXtreme PSU Calculator

          It's the most accurate and up-to-date one that I've found.

          There are two versions: free and "premium" (aka paid).

          I use the premium one so I get amperage for the +3.3V, +5V, and +12V rails. Last time I paid for it (about 2 years ago) there was a lifetime offer (200 years) for $9.99. I don't know if that offer still exists, but it shouldn't be that expensive.

            i found this one that seems pretty helpful

            http://web.aanet.com.au/SnooP/psucalc.php

            google ftw, every looks good there to me so i'm going to replace the dvd drive.

            sarc i checked any sort of config for IDE but i don't have any thing related to PIO or any way to change IDE operation in the bios at all.

              Get a SATA drive if you're going to get a new drive.

              That PSU calculator's pretty decent. I used to use it before the extreme one came into existence.

                The DMA/PIO setting isn't set in the BIOS.

                http://www.microsoft.com/whdc/device...e/ide-dma.mspx

                It's in the device manager under the IDE controller.

                  Ah thanks sarc, that didn't help at all. I'm pretty sure this drive is just dying. Everything was set for DMA.

                    Maybe the drive is dying. Is it making a lot of noise when you use it?

                      Re: Power Supply sufficient?

                      yep it sure is and disc speed tells me it can't test dvd's and very slow on cd's. I first recognized a problem when it wasn't playing a DVD very well and then tried to copy some files from a DVD and it choked up hardcore.

                      Yeah gotta be a dying drive so i'll replace it today.

                        What brand is the drive?

                        If you want something a bit more quiet, I suggest looking at a LG. They might not spin up as quickly as a Lite-On, but they're really quiet when operating.

                          Re: Power Supply sufficient?

                          I bought a new LG DVD burner and it's running perfectly.

                          I had an LG before and it lasted 4 years.

                          Thanks for the help.
