Help me pick a PSU

[crunchpepper]

The PSU in my system is a couple years old now, and I've deducted it to be the cause of my random and sudden system crashes after doing many test.

Now the real question, what do I even upgrade to?

I need something that's in stock through the shortage and isn't price gouged (and obviously gold rated efficiency and above 750w).

My system:

i5 7600k 

RX VEGA 56

and my PSU right now is the Corsair TX 750M.

What if you're wrong?

first test with a friends unit and see if the problem persists.

my friends and i don't have spares to test with it nor will i ask them to take their unit of of their pc that's a lot of work

MSI 650W AGF @ 90 USD is a decent unit

would 650W even be enough for a vega 56?

What is the problem you're having and what makes you think it's the PSU that is the cause?

 

I noticed this is your first post here, so I realize you didn't come here for troubleshooting help first.

 

If you went to Reddit first, I'll have you know that 99% of the people there are wrong 99% of the time.

no I'm IT certified and know a bit about computers.  My computer can't run at certain clock speeds it used to, so I tested my memory and it came clear. However when my cpu voltage clocks were higher, I'd get a memory leak. I get power delivery problems from USB that aren't caused by windows drivers. I get all the symptoms of a memory leak, without any indication that my ram is faulty. Unfortunately, I don't have a multimeter on hand to test my PSU more extensively but from the tests I did I deduced that it's my PSU and I'd be shocked if it wasn't.

It COULD be my motherboard but considering nothing in my BIOS is out of wack I highly doubt it.

That's not a PSU issue, that's your CPU degrading.

Nor could you make any accurate conclusions with such a (likely consumer grade) multimeter

Memory leaks are strictly software issue. Not RAM, not motherboard, not PSU, software.

Not a PSU issue either.

You was talking about system crashes, now you're talking about memory leaks ? What is it ? System crashes as in, reboots ? With BSODs or not ?

Random system crashes due to "memory leaks" usually caused by driver failure. Sometimes my windows will corrupt because of the memory leaks and I have to DISM through an ISO. 

No BSOD, I will get random blank screens (usually the color gray or beige) and I lose all access to my system and the only way to fix things is to force shut off. If I turn my computer back on windows takes a while to boot because of auto repair. My crashes are always in due to a driver failing but it has nothing to do with windows considering multiple reinstallations haven't fixed it. 

 

EDIT: I should probably add that whenever my windows corrupts it's because it's under heavy load and my entire system just shuts off. That's probably the biggest indicator but I always seem to forget to talk about that when explaining my problems because it's only ever happened twice. 

Another thing, most of the time my computer is usable. It's unpredictable whether or not these crashes will happen. Even under load, sometimes my pc is fine, sometimes it isn't. 
 

The thing is, when it seems like everything could be failing in the system it's probably the PSU. I've repaired many PC's with similar problems where it ended up being a faulty PSU.

That's amazing.  Never heard that from anyone else unless they were using PSUs letting > 100mV of AC ripple through to the motherboard and graphics card causing the VRMs to overheat on those components.  But never on a quality PSU.

Is anything overclocked or undervolted or changed from stock settings?  Have you checked the Event Viewer for any clues to system / software errors?

I feel like we have different definitions of a 'memory leak'.

https://en.wikipedia.org/wiki/Memory_leak

In computer science, a memory leak is a type of resource leak that occurs when a computer program incorrectly manages memory allocations in a way that memory which is no longer needed is not released. A memory leak may also happen when an object is stored .

Crashes with the display turning funny colors probably means either GPU or PSU instability (or more like it's cables/connectors are toast), you're right. The only way to diagnose that is to swap either the GPU or PSU for another one, do you have any friend you can lend them from for the time being ?

Memory leaks can cause windows corruption and the likes, but maybe I am using the term incorrectly there. I am purchasing a seasonic powersupply at best buy to test my system. I wouldn't want to ask my friends to take the power supply out of their system so I can test.

Everything is stock. I get event ID 10111 and 10110 when my system crashes.

PC components have a life span, my PSU could be meeting mine. Even the most expensive hardware can only last so long.

There are Seasonic PSUs that trip with Vega 56.

I think a man who quite literally made that PSU has some idea about the lifespan of PSUs lol. It's still possible that it's just faulty tho. For how long did you had it ?

I'd pick something else with Vega 56.

I saw one suggestion for that problem was to check that all the power cables from the PSU are firmly clicked into the GPU and other parts, and into the PSU itself.  If they are not, issues like yours can crop up. 

 

[crunchpepper]

UPDATE: New PSU fixed my crashing and instability. I'm able to overclock again. However my ram (when overclocked to 2666) leaks causing windows corruption. So there were TWO issues with my PC.

i even replaced the cables to my psu (at least the ones I could) and still got the crashes.

Yeah I've read about that, but it was with older models not the new GX-750 so I decided to take that risk since it was the only PSU in stock
