Possible issues with psu. Need help.

[nardvar]

Hello. I'm having intermittent proplems with system.

Power supply is a 6 year old Corsair TX 650.I have attached a screen capture of current voltage
readings and was wondering if they are within acceptable limits. Thank you kindly and regards, peter

Welcome to TPU! The first thing you need to do is set the system back to stock clocks. Then test for stability.

software readings mean nothing, if you suspect your PSU is faulty then a hardware multimeter is needed

Need full system specs:

Thanks for the welcome. It's appreciated.
This happens with stock clocks as well.
Five days ago I changed motherboard, cpu and ram. The psu and graphic card were kept
along with the 500hdd 720 spin and 125 ssd boot drive. Case as if it's important a NZXT S340.
It's black. Joy.
The motherboard a used Asus Z270-Ar had an issue in that one usp port was not working.
Found a broken off pin in the 19 pin 3.0. No biggie.
All new used components installed the system other then the usb went fine.
A day later when playing Titanfall 2 screen went blank system crashed rebooted
and found the bios screen artifacted with green horizontal lines.Not drivers as
windows wasn't loaded.Checked the bios to check temps and they were fine.Voltage information
was a something I could not process.Rebooted and found the windows logo now potatoe sized and
at the very bottom of the screen with fuzzy horizontal green lines.Into windows artifacts as well.
Shut down pc checked connections.All good no smells.Capacitors good.
Changed from display port cable to hdmi.
Set monitor to auto dp and hdmi.Was going to alternate from one to other a bit.
Rebooted into bios.Same thing to a lesser degree.
Switched cable again and encountered "no signal detected" Powered down
switched to hdmi and rebooted and "no signal detected" Case side open fans working on all devices
no excesive heat.A few things back and forth.Nothing. Card had officialy died in my book.My new
cpu a intel i5-7600k installed with just the right amount of thermal and cooled by a dual fan Cooler Master Hyper 212 EVO
has graphic capability and so with Titan removed it now through hdmi is
controlling my graphics without a hitch.
I took apart the Titan and checked thermal paste.Dry so I wiped it of with 99% and reapplied.
Stuck it back in.Same result.Just purchase a used 1070 oc (it's on it's way)and I hope this doesn't fry as well.
If it shows up the same results I know the titan was probably good so maybe a new mobo and psu.
BTW ran intel cpu check and memtest both passed.
Sorry no hardware testers.
Thanks for putting up with this babble and regards, peter.

Before replacing the gpu,

Replace the psu, it's failing.

software readings mean nothing, if you suspect your PSU is faulty then a hardware multimeter is needed

A multimeter is not even conclusive. Conclusive testing of a PSU requires the use of a dedicated power supply analyzer, or an oscillocope. And the PSU must be tested under a full range of expected loads from idle to maxed out.

Most multimeters are incapable of measuring ripple and other anomalies that affect stability. Therefore, if you suspect your PSU is faulty, and if you are not a qualified electronics technician with the proper test equipment, then swapping in a known good PSU with ample capacity is needed. If the problems go away, your old PSU is likely at fault. If you get the same problems, your old PSU is likely good. I say "likely" because I am not assuming all the power connections were tight and secure with the original supply.

Of course regardless the supply or its condition, you still need to feed it clean, stable power. For this reason, I always recommend every computer be on a "good" UPS with AVR (automatic voltage regulation). Also important for stable operation is a properly wired, and grounded to Earth ground wall outlet. For this reason, every home and every computer user should have access to a AC Outlet Tester to ensure your outlet is properly wired and grounded to Earth ground. I recommend one with a GFCI (ground fault circuit interrupt) indicator as it can be used to test bathroom and kitchen outlets (outlets near water) too. These testers can be found for your type and voltage outlet, foreign or domestic, (like this one for the UK) at most home improvement stores, or even the electrical department at Wal-Mart. Use it to test all the outlets in the home and if a fault is shown, have it fixed by a qualified electrician.

Did just that. Replaced with a Cooler Master Masterwatt 750 semi mod. Our local Staples store had one.They priced matched down from 119cdn
to 90 mirroring best buy.I have to say the young fellow helping me out there was awesome.
And is it just my imagination or are my downloads moving faster now. Power. Go figure.

Clean power is clean power. Ill get you info on the cm psu

Heres your model, it is decent.

Apologies for not responding to this earlier. Your obviously well informed and put some time into this response. It's much appreciated.Software if it's
available for testing devices on pc's is always nice if you don't have spare psu's or gpu's at hand.Hard testing at a shop is around $30 dollars. Many off us are enthusiasts and we buy and sell used of eBay usually at reduced prices so we can game at mid tier .


Anyway just to report new psu installed and the EVGA 1070 oc arrived.
Dirty dusty but hey $300 cdn so who's complaining. Installed and running without
any glitches. Screen is back to normal and rig appears stable but time will tell. Knock on wood three times, usually top of my head.Thanks again
for putting in the time to help out.

According to this photo, +3.3V, +5V, +12V are OK and within the ATX specs. CPU voltage also looks OK.
I assume that VIN 3 might be CPU I/O voltage and that seems OK as well.

There is a better software voltage monitor HW Info.

LOL Gotcha!

Great! Glad its working and thanks for the followup.
