I purchased this psu along with my new build back in 2015. Last couple years I started having a weird problem when i power on my computer, occasionally maybe once a month it would turn on for split second and turn off again. But if i press power again it would turn on normally. But recently it has been happening very frequently almost every 2 days. Today when i went to power on it turned off soon as it turned on did it 3 times before powering on normally. Is my psu dying? Once computer is on i can do everything normal.

Did your PSU come with the "power On jumper block -- that you place on the 24-pin cable ?
Confirm All connections, including the cord from the wall to the PSU
Does your MB have a Display ? what code does it show before turning off ?

It does come with power on jumper block. All connections are secure, my mb does have a code display screen but i have not checked it due to tower window facing a wall. I will check tomorrow morning during a cold start see if i get any code. But in the mean time does these symptoms sound like a failing psu?

Is your hardware overclocked? If yes, it could be that your motherboard is having a hard time booting at the oc settings you want to be applied.

If you suspect a PSU problem, buy or borrow another one that's just 'good enough' and try it. It's always nice to have a spare one laying around, even an el cheapo that will just 'do the job' until you can get a better one. In the wonderful world of electronics, sometimes the only way to troubleshoot/isolate a bad part is to swap it out with a new/known good part..You could also try it both with and without ECO Mode enabled..Sometimes ECO Mode causes problems. Use the OuterVision Power Supply Calculator to estimate your system wattage need.

If you disconnect ALL other connections to your PSU - except the 24-pin & installing the jumper Block Always starts the PSU --> is is Not a PSU issue

Okay so i finally got to it today. Did the psu testing with the jumper block and fan turned on no problem. I only did the test one time due to it working the first try, is testing it once suffice? After the test went to power up my system same thing, it turns on and off twice within a second then it boots up. The debug code display on my mobo is not very reliable, it was throwing all the codes and yet my pc runs fine after its powered up. I also changed my cmos battery for the first time while i was diagnosing. I noticed the original cmos battery which is over 5 years old seems to be dead when i put it in one of my led remote controller to test the battery. From what i search on google a dead cmos battery wouldnt hold system setting or things like time but i never experienced those signs. I also went ahead did a cmos reset, so no cpu or ram oc at the moment. I will be reporting back tomorrow again to see from a cold start if problem persist with non oc settigns. But i had these oc settings over a year with no problems. Could it be a dying mobo? i bought a fancy mobo asrock x99x killer hoping it would last long.

intermittent cold boot issues always have a tendency to be a pain to pin point. Main culprits: - Power Supply
- Failing CPU or unstable overclock(CPU degradation is very real)
While you cannot rule out RAM or the Motherboard, RAM usually would have shown you some crashes/BSOD's since 2015 among, other boot issues. Run Windows Memory Diagnostics or Memtest X86 just to be on the 100% sure side. be sure to test each module individually. Motherboards............well I've built a lot of systems in my life(vast majority were Asus and Gigabyte boards) and I've maybe seen 1 motherboard fail at a really really ripe age. While you cannot rule it out, I would say it's one of the less likely candidates. I think the best advice so far was Bob's, get your hands on a different power supply for testing sake, and plug in only what needs to be plugged in and see where that get's you. If things seem to "normalize" start reconnecting your other devices and keep an eye on it. I have seen failing SSD/HDD, and also CD-ROM drives cause a variety of different boot problems. p.s. It's normal to see a barrage of different post codes during boot sequence. Which leads to the next question; When this issue happens which post code does your motherboard display?

Thanks, yea ive been looking for a direct replacement of my current one but seems sold out everywhere and evga representative told me not sure when it will be available again. Now come to think of it, my boot issue didnt always started with computer turning on for a split second then off. The first ever symptom i had was trying to power on the computer in the morning but nothing would happen. I have to manually press the case power button again to startup the computer. This would happen maybe once every 1 or 2 month then a year later it started turning off soon as it power on then i have to manually turn on again. Only last 2 month it would power on and off looping twice before it automatically starting again. No other symptoms either during gaming or full cpu/gpu load. edit---- Oh i forgot to mention i also use a ups by cyberpower since 2015 when i build my rig. But ups doesnt seem to be having issues or dead battery.

That's a fact, especially if you want an EVGA unit, and prices are nuts..Maybe see if you can find one that's just good enough for now..Walmart, Target, Staples, Office Depot/OfficeMax other such similar places sell PSUs.

I found a supernova g3 thats available but alittle confused with their specs. Both g2 and g3 has same rear connectors but spec one says 6 x 6+2-Pin and the other 2 x 6-Pin, 4 x 6+2-Pin. Also g3 has 9sata connector but g2 has 10. Im confused.

What’s in the Box: 850 G2 What’s in the Box: 850 G3 The first number in parenthesis is the cable quantity, followed by the quantity and type of connectors on each cable. Does that help?

So the pci express connector numbers just different quantity of cables that will come in the box but both psu operate the same with same rear connectors? If the rear connectors are the same why does one say 9 sata power connector other say 10?

Yes. And the 850 G2 says it comes with two SATA power cables that have three connectors on each of the two cables, and one SATA power cable that has four connectors on it. The 850 G3 says it comes with just three SATA power cables that have three connectors on each cable. The SATA power cables will have different lengths. Each unit also comes with two 'Y' cables for the PCIe/VGA that has one cable coming from the PSU and splits off into two connectors for a graphics card, as well as straight single-connector cables that don't split off into two connectors. See also: Which EVGA Modular Cables are compatible with my PSU? in the EVGA FAQs. If you have any more questions, don't hesitate to ask.

Thanks, it seems g3 is in back order not ready to order i misread it. Ive not turned off my pc in 2 days lol i dont want my (5)HDD to get corrupted during the on and off cold start power up. Im planning to keep it on till i get a new psu to test out. I did a overclocked cpu stress test last night for an hour and no problem at all. Im really starting to think i have a really weird psu problem.

If you're going to leave your box running non-stop, it wouldn't be a bad idea to have a monitoring program running that will shut it off automatically in case of CPU overheating should something catastrophic happen when you're not around. Real Temp as an 'RTShutDown.bat' you can set to run.. MSI Afterburner has a 'System shutdown' application built-in..You can point HWiNFO to the 'RTShutDown.bat' in Real Temp to run..Set the shutdown temp at what you want to..Just some ways here to be safer.

With system at idle gpu can overheat too? Can you please explain alittle more on setting the shutdown temp with real temp. Im currently using hwinfo64 to check all my temperatures and stats.

Anything can happen, ya know.
Open the Real Temp Settings.
Checkmark Alarm.
Set the CPU Temperature and/or GPU Temperature to your desired shutdown temp(s) by typing the value in the boxes and press Enter.
Open Alarm EXE and change the Files of type to BAT Files (*.bat) in the dropdown.
Then click on the RTShutDown .bat file..Then Open..Then Apply..Then OK.
That's it.
If you just wanna run HWiNFO, you can right-click on any temperatures, then Alert Settings, then Enable Alerting, then set the temp values, then in the Run a Program box you can point it to the RTShutDown.bat if you wanna go that route..No need to have Real Temp running, only it's RTShutDown.bat is needed.
It's a good idea to intentionally set the temp threshold to a low number that you know you'll hit just for testing to see how it works..Then raise it to the shutdown temp you want to roll with.

My pc gotten worse, now it wont even boot up. Pc turns on but no display no hdd light just cpu/gpu/case fans running. I finally able to get a Ezvga g3 1000w but still the same. I wonder if its a bad psu or mobo. If a psu is faulty will computer have trouble booting up or operate normal once pc is booted up? I did manage to boot up once out of the blue, as long i didnt turn off my pc it ws able to stay on.
