Computer Turning Itself On And PSU Question

[SuperShermanTanker]

So my PC turns itself on and yes you heard me right it turns itself on and I already narrowed it down to only having the motherboard and my Corsiar CX750M power supply hooked up with only the CPU and a single stick of RAM in on the old motherboard and it still turned itself on then I RMAd the motherboard and it was fine until I started to overclock my CPU and now it turns itself back on again. Now the motherboard is brand new and it did work fine without self powering on for a few months until I tried overclocking the CPU and now I'm wondering if it's just my power supply since it isn't the highest quality one and probably might not like the voltages from the overclock. I do want to test a different PSU but the only other spare PSU I have is a 5 year old Thermaltake TR2 500 watt unit and that isn't the highest quality thing either but it's the only other PSU I can use to test it and I just don't know if I should trust that PSU in my main machine for a week to test it to see if it is my Corsair PSU and not the motherboard again. The Thermaltake PSU I have does work fine and powers up fine but I don't know how well it'll handle the 350-400 watt load from my main desktop under load for a long period of time since I do edit videos on my main desktop.

My computer used to do that too with a PSU of questionable quality.  Putting it on a UPS solved it, and I have also since upgraded the PSU (at a later date).  I haven't tested, but I suspect that if I were to plug it in directly again, it wouldn't have the problem.

Ooooo...the TR2, totally not a T7 PSU  

 

Although I think it's the PSU, have you tried uplugging the case's power switch from the motherboard? Maybe that's short circuiting? 

[Bananasplit_00]

probably the power button lol, might be PSU tho if mains power isnt the greatest. my computer will also turn itself on but thats only if i leave it in sleep mode for around 3 days usiually

It's not the case I narrowed that out of the equation on the old motherboard

kay then its the PSU, probably your wall powers foult, a better PSU would have more capacitance and better caps overall and minimise any problems there i would guess

Yeah, sorry if it wasn't clear from my initial post, but I strongly suspect the PSU as well.

Then what should I do should I just try the thermaltake or should I just drop the money on a new PSU

If you have another one in the house and don't mind the time necessary to do a swap, try it.  If not, or if the problem persists, I'd buy a good one using the list on the forum here (link in my sig)

the TR2 is a pretty crappy unit, i would sell both and drop the money on someting like an EVGA G2

I got this as a my only spare one that not a no name cheapo one

Yeah I might just do what was mentioned above...

pick up used Delta units of your local used market, there are usiually a few around at 370W-500W for just a few $ because people think they are shit because they are greay and a "no name" brand

[SuperShermanTanker]

So I came to the conclusion I'm just going to get a new better quality power supply at microcenter tomorrow and see if that fixes it

That'll fix it it's not a EVGA G2 but they are pretty much built the same

Yeah, I have a friend's dead TR2 600W that went up in smoke that I threw away already...the dog was having fun dragging it on the floor...

 

The new PSU should fix it. I do find it strange that the PC turns itself on. That's a new one for me.

 

For me, my PC would turn itself on due do the onboard ASUS Wifi card on the motherboard. I remember if I installed some ASUS Wi-Fi software it would turn the PC on randomly. I forgot what the software was supposed to do at this point and I just removed it according to what others with the same board have said online.

Excellent choice, and thanks for shopping at Microcenter ^^

In my house the electrical cables in the wall are so old they are made of aluminum and the house is wired so badly that if you do something like turn on the microwave the lights flicker a bit so I'm thinking it's just the fact of bad electrical in my house messing with the machine making it turn itself on

Well, I would think it would make the PC turn off, rather than on. The PSU relies on the signal wire to turn on.

 

Yeah, my house is wired with aluminum as well. At least we have the proper gauge of wire so no flickering. However, the street transformer is getting old and during most storms our power goes from 80 to 110V according to my UPS.

A UPS is the next thing on my list to get but for now I'm hoping this power supply I bought has enough filtration to filter out the power from my wall
