    So my Antec 430w ATX psu blew out this afternoon. I guess it was overdue, it was over 4 years old and I have a pretty dusty office, so it wasn't unexpected. I bought the Dynex 520w PSU from bestbuy. Popped it in. At first, all seemed well. Worked okay. Not terribly happy with the PSU as it doesn't have a power switch on it, but I can live with it.

    I have a very basic setup, ATI Radeon 4600 graphics card, quad core 2.4 intel, 4 gb standard RAM, dual tuner TV card & all the boring shit that goes with any TV.

    Anyway, fast forward about 2 hours. Suddenly my PC is randomly shutting down without warning. Reboot, barely gets to the desktop & shits the bed again, turns off.

    I disconnected the TV card, my firewire card, and an extra case fan I was running, and as of now, it's up. It's preforming well at this moment, but I have no idea how long this is going to last.

    Question: Why would a Dynex 520w shit the bed where I was running just fine with a 430w Antec for years?

    Dynex? Didnt even know they made power supplies.

    They make TV's dont they?

    Id return it and get a name brand - Antec, Corsair, Cooler Master, etc.

    Check you motherboard for blow capacitors. PSUs generally go bad because of blown caps and they can and often do spread on to your motherboard. If its randomly shutting down I would guess that over bad, new PSU.

    EDIT: A blown cap will have to top poped up. They should all be completely flat, if it is bubbled whatsoever it is bad.

    Yeah, but it's running now, leading me to believe that the PSU can't handle the load. Ergo, bad PSU.

    A blown cap will cause sporadic like running slowly, programs wont open, and randomly shutting off the PC.

    I completely agree, but I did a visual inspection of my caps when I was tearing my box apart, didn't see anything obvious. I work in a hospital that's a Dell shop so you can imagine I've seen shit tons of blown caps.

    I did have my eye on a corsair, but frankly I'm on the balls of my ass financially right now, and the comparable corsair PSU was $120 and the one I got was $65.

    Good idea. Be sure to run that rig 24/7 in the meantime so the Dynex can do as much damage as possible. It's always a wise move to buy a critical system component from a company that sounds like they make dryer sheets.

    Meh, that PSU stays up for like 20 minutes then craps out. Funny thing is, I can see the LED idiot light on the mobo still lit; with the original one that light was pulsing on & off, quick flash blips. That told me that a cap on the PSU probably blew out, preventing the power from going smoothly through the unit.

    I gave up on the dynex, and am on my laptop now. Not happy about it, but what else is there?

    Sonovabitch. I got the corsair, popped it in, and this fucker doesn't even pretend to want to power up my board. I guess the mobo is in fact shitted up. Damn.

    I have the same problem. Mine is only when I try to play any video games or push my system besides watching porno and netflix.

    I swear to god, the ONLY consistent thing about homebrew PCs is the complete lack thereof. I tore my PC completely apart today, reassembled EXACTLY the way it was, and it fired up without so much as a twitch. (Using the Corsair, of course, though I now doubt the original Antec was dead to begin with.)

    Fucking silly devices. Probably had a case of thermal creep, and when I reseated everything, shorted something against the frame. Stupid.

    At least all is good in my office world once again, and I'm sitting in front of my 22" and 32" glory instead of my 17" laptop display. That sucked.
