Is my PWS/PSU my problem??

[Concealed_45]

First post, hope im in the right  section.

 

ASUS M5A97 r2.0, FX-4300, MSI GTX 970 100ME, Win10, 650watt unknown PWS, 5 case fans, dual fan CPU cooler.

 

I added the GPU recently as a step toward upgrading. MB and CPU is next. But the computer has started just randomly shutting off during games. It will not power back up untill I unplug it, cycle the PWS power switch and plug it back in. I have run temp monitoring softwares to see if I was having a temp. issue, but GPU never gets over 70 and CPU over 55. According to all the calculators the 650 PWS should be plenty, but I have no idea what brand it is, came with a kit. The system has been running about three years. I am guessing its the PWS but looking for any input on other possibilities. I have a new PWS on the way.

 

TIA

uhhh... What's a PWS?

Personal Weather Station

 

(I assume PoWer Supply aka PSU).

If you have a multimeter, probe the 12V rails when the PC is under load. If it drops too much then that would explain it.

Power Supply/PSU/PWS....most call them PWS around here, lol

Im not sure how or where to do that. I have a multimeter, would I be looking for voltage or amperage? and can I just probe one of the extra Molex connectors?

[Huntsman]

Voltage. NEVER NEVER probe for amperage. Probe between yellow and black wire. That's 12V. Red is 5V and orange is 3.3V.

okay, thanks

I get 12.02v at idle on Win10 desktop. When running Prime95 along with MSI Kombuster it drops to 11.93v

[Huntsman]

what about the other rails?

I dont know how to tell what the different rails are or where to check them. I probed the cable with the molex connectors that has only a couple fans running from it.

[Huntsman]

Probe between the red wire and black then the orange and black under load conditions. This is to test if your PSU is faulty. Although this is only a basic test, a more comprehensive test is done using a load box and DCPA.

5.15, and 3.14

[Huntsman]

5V is slightly high but otherwise normal. The next step is to probe the same voltage rails using oscilloscope if you could get your hands on one. Look for large voltage ripples.

[Concealed_45]

Okay, thank you for the help. I doubt if i can get an oscilloscope though, or anyone who knows how to use it if i did. I guess if the new power supply doesnt help i will have to accelerate my schedule on upgrading the MB and CPU.

No-name PSU? Replace it my friend. Check out the PSU whitelist in my sig.

I found it was a kingwin when i removed it, replaced with a EVGA, so far so good, but i havent run it enough to be sure yet.
