Hi everybody.
 
I have a trouble here with a Supernova G2 1300w that i purchased brand new 4 years ago. The voltages appear to be wayy lower then supposed to be, so the PC will hard crash at the slightest attempt at using the Videocard. Windows desktop is fine, google chrome is fine too as long as i don't go on Google Map's Satellite view. Compress files or load the CPU with a benchmark will do but the voltages will go uber low. Obviously, games won't work anymore.
 
At first i thought is was a videocard issue because it's apps that use it that crash. But after having reformatted twice and tried countless drivers revisions from 2017 and 2018, i was sceptical. Finally, a co-worker used it for a couple of weeks and didn't had any problems with it. So it's ok. I also thought that windows updates were causing it as i had a major update around the time when it started, however, i re-installed windows with an older version i had in a USB key but it didn't do the trick.
 
Finally, yesterday i decided to check the voltages with HWMonitor and that is what the voltages are with ZERO load and ZERO Overclock. (
, , 
If i run a CPU Bench 12v will take a big hit and drop in the high 10's and 3.3 and 5 will be more like 2.7 and 4.1... In the Bios, the 12v value is in the 11.6\11.7 range.
 
Lastly, my system is old but still does the trick as i don't game on my PC as much as i once did.. :)
 
-Xeon X5650 @ 2.66ghz
-Asus P6T-SE
-24Gb GSkill DDR3 @1333Ghz
-Powercolor PCS+ 290 @ 1.04Ghz (Stock)
-2x Samsung 860Evo 500Gb Raid 0
-1x Adata SP550 240Gb (For Virtual Memory (LOL))
-Corsair Watercooling (For Silence!!)
-EVGA Supernova 1300 G2 (Overkill! For peace of mind. I had my fair share of crappy PSU..)
 
If you have any ideas, i'm more then willing to check it out! Note that i also checked the Serial Number and it's not affected by the 2013 Recall.
 
Thanks in Advance!
Marko!

    Sounds like it's defective. Have you checked your rail voltages with a multimeter while the system is under a load?

    I didn't because i don't own one. What i tried is...

    -I tried cleaning it with a compressed air can but as i clean both my PC and PS4 every 6 months there wasn't much dust.
    -I tried to switch those modular connectors elsewhere on the PSU when possible (Sata, VGA, CPU).
    -I tried to connect the Computer directly on the wall. (I use a surge protector that also protect my screen.)

    I'd highly suggest you get a multimeter as software readings can be inaccurate.

    I was able to borrow a friend's Snap On Multimeter. I'll check it out later then i'll report back. :)

    Are you using One PCIe Power Cable to the Graphics Card or One Power Cable?
    If using only One  PCIe Power Cable Use Two  PCIe Power Cables and see if your Graphics Card crashes.
    Maybe add a EVGA Power Boost to your PCIe Slot for extra power.

    Your Asus P6T-SE X58 is showing it's age maybe.

    Hello,
     
    Welcome to the forums. Judging by the HWMonitor, it appears to be undervolting. I will be sending you an email directly on this.

    Is this a known issue, I asked because I have of the 1300 G2 and none of them would power up the X299 Dark Motherboard.

    The Videocard is connected with 2 Red wires (VGA) and the board and disks with black wires (SATA, CPU, tralala). Same as when i installed it 4 and a half years ago. It all started to act weird a while ago (Last May or June) but i didn't had time to check it out then, with my son and divorce taking much of my time and the job taking the rest of it... :(

    Good thing it is still under warranty.

    Little update.
     
    I forgot that fancy Snap-On Multimeter at work so precise voltages check will have to wait until tomorrow... However, i switched the videocard from the 1st PCI-E 16x to the second one and voltages improved in the Bios by at least .2 to .4 volts at all voltages (3.3, 5 and 12) and the videocard didn't crashed again in a benchmark. I don't understand why... I will definitely try to check those voltages tomorrow and i also ordered one of those neat Power Boost thingy that bcavnaugh talked about earlier... Perhaps a PCS+ 290 is a little too much for a old X58. Perhaps...
     
    We'll see about that... :\

    Little question for the pros. Can a fried PCI-E 16X slot still work at low load? The computer seems to work allright with the videocard on slot number 2, however, when the card was still on the 1st slot, everything was normal at low load. Those crashes only happened at high loads, when a program was asking too much from the GPU.. Can't wait to properly measure the volts the PSU is outputting tonight...

    I wouldn't think so.

    Keep us post after you have made the changes and added the Power Boost.
     
    Also run your Serial Number here to see if shows up https://www.evga.com/articles/00803/

    It's not on the recall list. :)

    Little Update. The PSU is fine!! Voltmeter confirmed 12v at 12.1v and 5v at 5.08v. It seems like it's the board that is having trouble supplying all the power the Powercolor PCS+ 290 is demanding for whatever reason. What is weird is that it worked, like 2years 24\7, without issues and now, all of a sudden i had to move it down on the 2nd 16x PCI-E slot for it to work in 3D apps. I allready ordered a power boost so we'll see if it's going to aid that old, but otherwise, perfectly fine PC. 
     
    Wait and see as they say...
