Solved

Might need a new PSU.

I'm wondering if anyone knows of a powerful but compact PSU.

I'm looking for a PSU that can spit out at the very least 650w of power but more would always be better.

I searched for "compact but powerful PSU" in google but that didn't garner many results and the one that I did get was only around 400 something watts which isn't enough.

Price range doesn't really matter but if I had to put a limit then my spending wouldn't go above 150$.

I can use all the help that I can get.

  1. Hi :)

    What PRECISELY do you mean by COMPACT ??

    Psus come in certain sizes...BUT some manufacturers like Dell put weird sized PSUs in them.....in which case you will have MAJOR problems finding a more powerful one...or even the same one...

    All the best Brett :)
  2. You're looking at a standard ATX power Supply for that sort of range. I have a 450W Silverstone uATX supply myself.

    What are your system specs? What form factor PSU does your case support?

    I have stock everything except for GPU. My GPU is an XFX Ati RAdeon 6870. It requires a minimum of 500watts and needs two 6-pin PCI connectors.

    My current PSU is: www.newegg.com/Product/Product.aspx?Item=N82E16817152042

    The PSU's dimensions are 6" x 3.5" x 6.25". As of right now, it fits . . . barely.

    The PSU that I had before was this: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371023

    It's dimensions are 5.5" x 5.9" x 3.4" and it fit perfectly into my case.

    The reason why I'm looking for a new PSU is because my current PSU has one PCI line that splits into two 6-pin connectors but my graphics card apparently requires two separate PCI lines, each with its own 6-pin connector.

    But I've looked at several PSU's and they are all too big to fit in my stock case.

    So I've come to you all for some help. Maybe someone here has a powerful PSU that isn't too big.

    What case? Those are both standard ATX PSUs. There is little variation in the size of ATX PSUs...the length is the only measurement that will change on higher power PSUs. Current sale on Antec PSUs at Newegg. Great little PSU with enough PCIe connectors for your PC is the Antec Earthwatts EA-500: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371035

    EA-500 has more than enough power to run your rig...I'm running a 6950 on a 520W Seasonic. Great recent article on PC power consumption showed that an i52500K and an HD6870 under full stress (Prime95 and Furmark) only used 271W: http://www.silentpcreview.com/article1245-page1.html

    I personally wouldn't put a Raidmax within 5 feet of my PC. That being said, yours should have sufficient connectors for your GPU. It shouldn't matter that both PCIe power connectors are on the same physical cable...they are rated by the mfr to provide the required power (75W) to each PCIe connector. Have you tried connecting everything and booting?

    EDIT: BTW the EA-500D has the same dimensions as your Antec Basiq PSU.

    Um . . . wow. I don't know what t say. So basically, XFX is trying to sucker my not-so-tech-savvy-ass into buying their PSU's that have 2 separate PCI lines when it shouldn't matter since I have a 700w continuous PSU with almost 3x the minimum required watts. And I don't even have an i5. I have an AMD quad-core something (not sure the exact make and model but it's Ghz is 2.7).

    Now that's two people that I've heard tell me that Raidmax sucks even though Newegg customers gave it 4 stars. I'm starting to worry about the money I spent on this PSU. It won't blow up or anything, will it?

    As for connecting everything and rebooting . . . I've connected everything yet my monitor stays blank and doesn't register the GPU. I'm not sure if it's because of the fact that my monitor is just stupid or if I had a problem with the PSU. I went for the "obvious" problem which was that my PSU didn't have 2 separate PCIe lines.

    Thanks for your input. I'll keep my current PSU and just try to fix my monitor or something.

    Once again, thanks.

    It's not likely to be your monitor. Boot-no-video troubleshooting guide: http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems
    You could have a bad PSU...i wouldn't doubt it with a Raidmax.
    Try the paperclip trick to see if your PSU will start up: http://www.youtube.com/watch?v=u0OKmIuNtmI

    I'm sure its not the Raidmax because it turns on and runs everything fine on my old GPU.

    But if it could be the problem of the PSU then I suppose I'll take it to Fry's and get its voltage tested.
