Computer crash, fans, led and power button still work!

Hey guys, so I bought a new graphics cards last month, a GTX 770 4gb. However since maybe one week, my computer started crashing for apparently no reason once or twice per day. The fans, LEDs, power button and all that's USB powered still seem to work. I think the problem is with my PSU, as my graphics card needed 2 x 6 pins connector and I didn't have any available. So I used two 2x molex to 6pin adaptors. It would make sense that my graphics card would need too much power for my PSU. Still, before buying a new PSU I would like your opinions on that!
Thank you guys!

  1. Well what PSU is it? Make and model please.

    Though needing two additional 6+2pin adapters is a bad sign right off the bat.
  2. Use this PSU calculator to determine if your PSU is out of it's range. That's a good start. Just plug your system into the calculator part by part. Once you do, post your findings here.

  3. The thing is, it's an Orion PSU, but there isn't any sticker on it telling me the model or the Watts. I'm trying to find the model on Google, but I don't seem to find anything that look like mine.

    I'd say it's time for a new PSU no matter which way you look at it. Sounds like it is very old and outdated. And more than likely severely underpowered. Older PSU's tended to have less wattage anyway because all of these power hungry GPU's weren't available.

    UPDATE: I was going through my older posts and noticed that I recommended a new PSU, but I didn't exactly say what kind. I recommend that you go with Corsair AX, AXi, RM, CS, or TX. There are rumors that the RM series has faulty secondary capacitors, but I have researched it and have found NOTHING to back that up. The AX and especially the AXi series by Corsair are as good as it gets in the PSU department. Both are "80 Plus Platinum rated, and the AXi (ONLY the AXi, not the AX) series is the only digitally controlled PSU on the market. The AXi (again ONLY the AXi, not the AX) also comes with a Corsair Link module, which along with the Corsair Link dashboard software (Corsair Link software is available as a free download from Corsair's site) gives you the ability to monitor/tweak your PSU in many different ways, including the fan. The AX and AXi both come with an industry leading 7 year warranty. You may as well call this a lifetime warranty because no one who games keeps a computer for more than 7 years. (I assume you game because of the high-end GPU)

    You will pay more for a Corsair, but you get what you pay for. I own a Corsair AX860i and absolutely love it.
  5. Yes, I'll buy a new PSU, but it's strange because it's not that old, I built my computer myself in July 2012. I guess the guy who sold me the pieces wanted to sell his last old power supply. Your test says I should get at least 472w, I'll go with something like 650w, I guess it should be alright.
    Thank you guys!

    Whenever you purchase a PSU, don't buy the cheapest you can find. Find something at least in the mid-range. Cheap PSU's = more problems than you want
  7. Agreed, and if you HAVE to go cheap, the "cheapest" I recommend is the Corsair CX/Builder lineup.

    I went all out with the AX860i. Yes, it's expensive. BUT....it's worth it.
