Where is the problem and is my psu enough?

AvadaK · Aug 5, 2016

So I had these weird power down-spikes on my gpu after installing new motherboard and cpu. At the same time drivers(and games) were crashing, clock speed dropped etc. I took the gpu out and we are running pretty much fine with integrated gpu, some lag spikes rarely but thats normal I quess. So im asking is my psu dying or can it handle the followings:

PSU: Gx 650w bronze
CPU: i7 6700k
MB: Asus Z-170-a
Old GPU: Gtx 660 ti
New GPU I've planned: XFX Amd Radeon RX 480
RAM: 16gb ddr4
HDD: 1gb
SSD: 120gb

The psu is old and not that good, but can it run with that config? If not, I might have access to Corsair 550w, is that enoguh?

Pics of the problem on old 660 ti:

Sounds like indeed your power supply is dying. If it is a cheapo one, don't use it to run your pc anymore.

Which corsair you have access to? Corsair VS, CS, CX (not the new CXM) series is not that good either.

My cousin just said one day he had one, didnt ask more. Prob. few years old, would 550w be enough to run the system? I dont have the logs from that but when I played H1Z1 the drivers crashed and windows wasn't able to recover them so the screens stayed black. Can the problem be on psu and gpu or is it just one? Before installing mb and cpu everything was fine.

Cooler Master GX is not a good quality psu. To be sure it is indeed the psu, why not borrow a quality psu from someone and test with that? As you mentioned aster removing the gpu (this reduces load in psu) the pc works fine, i assume it is gpu.

550w will be fine. You can run your system with a good 450w. But first ask the model of the corsair psu.

So I asked and he said that its Corsair 430m so is it just the CXM u mentioned? Outervisions calculator says the recommended psu wattage is 385 for the system with rx 480 and 426w with gtx 660 ti, so with new gpu it would run fine or is it a bad quality psu? One more expensive solution would be to first buy a new 500-650w psu and then if the problem still exists, buy a new gpu.

VS is dead last in terms of Corsair quality.

XFX 550.

AvadaK · Aug 5, 2016

I guess I'll buy that one. How about testing the system with rx 480 with that 430w, and buy a new psu after few months?

Inkiad · Aug 5, 2016

You did not mention the model. May be it is the CS430M. If so, not good either. But you can run it for a few moths in emergency.

AvadaK · Aug 5, 2016

Inkiad :

My cousin isn't home atm, but I think it's the CX430M, so would it be enough? I didnt find the power consumption of the motherboard(asus z170-a). So it'd be fine? Only a few months.

Inkiad · Aug 5, 2016

It will be ok, yes. If it is indeed CX430M

Otherwise buy a better one asap, the ones recommended till now.

AvadaK · Aug 5, 2016

Inkiad :

Got a confirmation that it is indeed the CX, not sure if m or not. Is the difference big and you said "otherwice", does that mean that if it runs fine we dont need a new one? Also is the diffrence between CX430M and non-m that big?

Inkiad · Aug 5, 2016

Yes it is pretty big. Non m's are widely known for failing left and right. There are also some reports of fire hazard.

AvadaK · Aug 5, 2016

Inkiad :

Yeah, well im getting that one for testing, it should run with old 660 ti just barely. Maybe the power save-mode will do something. Both of you thanks for answering and helping with this problem

Dark Lord of Tech · Aug 5, 2016

I would get at least a decent 550w.

AvadaK · Aug 6, 2016

Yea, if everything goes fine and I'm sure the psu is the problem I'm getting the one you suggested. Just when I have enough money.

Old thread i know, just tested another PSU and the problem is still there. I ordered the MB from Germany and i'm from Finland, dude from Asus told me to ship the mb back to germany for rma, anything I can do? That would be like a month without pc.

Inkiad · Aug 11, 2016

With which psu you tested?

AvadaK · Aug 11, 2016

Inkiad :

The CX430M, lowered gpu max power to 80% just in case.

Inkiad · Aug 12, 2016

Make sure you installed your graphics card and its driver appropriately. Do a clean install of drivers.

AvadaK · Aug 12, 2016

Inkiad :

I have reinstalled them with DDU twice like a week back. No difference. So Germany it is?

Inkiad · Aug 12, 2016

Unfortunately yes.

Or take your pc to a local computer repair shop to make sure it is indeed the motherboard. They are willing to help most of the time.

AvadaK · Aug 12, 2016

Inkiad :

Thanks for the help, ye sure I can test that.

Where is the problem and is my psu enough?
