Frequent Resets - PSU???

I completed my first build a few weeks ago and everything is perfect except on thing...resets. My system will, seemingly randomly, reset - no shutdown procedure, no power off, no lag time (the LEDs dont even go off before reboot). I have some ideas of what the problem might be, but I am not very tech savvy so I am looking for some help from all of you who know what you are doing. Here is what I believe to be the relevant info (let me know if you need more):

Resets are random, but tend to happen more in the morning hours than in the evening.

There are no temp issues - the system is running quite cool...def not overheating

I am not running a crazy power-hungry sys: 1 HDD, 1 DVD-rw, HD 3850, E6750, 2GB G.Skill, Gigabyte DS3P.

My PSU came with the case :rolleyes: - 500 w, with 22 amps on 12v.

I have four fans, all of which are molex.

Ok, so here is my diagnosis/questions/idiotic notions. I am mostly guessing this a PSU issue and that I should get a real power supply. But I have no way of testing to make sure this is the case, so before I drop $100 I want to be reassured. The only other idea I have, which may be totally asinine, is this: is it possible that my MOBO is forcing the resets based on the fact that there are no fans plugged into the MOBO for sys fan or front fan? I am wondering if, at a certain temp that isnt that high, the MOBO goes to control a sys fan, finds that there isn't one, and resets.

Here are my questions? Does this seem to be a PSU issue? Will I solve this issue by getting a reputable and more powerful PSU? Could this be at all related to my fan setup? If so, is there a way to adapt the molex to the small three-prong MOBO fan port?

I appreciate any and all advice, suggestions, or ideas. Thanks all.
 
The only fan most mobos care about is the CPU fan, and a lot of BIOS have an option these days to disable even that. I doubt it's your fans. Sounds more like either a PSU issue or possible memory faults.
 
Thanks for the reply, EvilTwinSkippy

What do you mean by memory faults? I dont know that term. Are you talking timing and such? I am not OCing; as a matter of fact, I have been running my BIOS's failsafe defaults.

I came up with one more theory. I have noticed that the reset almost only happens during the morning. I checked my apartment's circuit breaker panel and found that the outlet I am using is on the same circuit as my kitchen appliances. I further noticed that the resets seem to only be happening while my coffee maker is on.

This could of course be completely coincidental. I'm not really sure how to test that theory either due to a severe lack of outlets in my apartment.
 
I know nothing but most of these new graphics cards require a +12 volt with a amp rating of about 22 on one rail. I myself run 50 amps on 1 +12 volt rail.:)

With a graphics card 22 amps + whatever the rest of the computer needs.
 
Thanks for the reply crewzen.
i suspected this might be true. I looked through all the documentation that came with my card and could not find power requirements, or I would have done the math. I can, and should, look into that more though. I am sure I can find the numbers somewhere.
 
What PSU is it? Most PS's that come with the cases(cheap ones) wont work with much.
