How much can a 450W psu handle?

Naipross · Oct 18, 2017

I've got a corsair vs 450W psu and now I've some problems and just want to know if it's the psu. My pc just restarts when I play csgo, in the first rounds it just restarts, and it isn't overheating I just played another game for 45mins then withed to csgo and it crashed. I found in the eventvwr.exe that I could have turned off due to my psu. So is this psu enough for my pc? Just got the cpu cooler and it started shutting of about one week after the upgrade

My Specs.
Cpu. Amd x4 Athlon 870k
gpu. asus gtx 750to oc
ram. Kingston HyperX 1x8Gb 1600Mhz
ssd. Kingston HyperX Fury 480gb
MoBo. Asus A88XM-E
cooler. Cryorig M9A
PSU. Corsair VS 450W

Your system is not a power hog by any means.

Please post the specs on the power supply(EDIT. how did I miss that it was a corsair).

[strike]Not all 450 watt power supplies are made the same.[/strike]

Your system should not draw much over half of the power supply rating.

If it ONLY happens in CSGO, and other games work fine, I would rather not blame hardware.

FD2Raptor · Oct 18, 2017

If the different games that you tried is at least equally if not more demanding than CSGO then the problem may be else where, but, the Corsair VS 450 green label is notorious for dropping the main 12V rail under heavy load so that's your no.1 likelihood of where problem lies.

Naipross · Oct 18, 2017

the other game is more demanding. it only restarts once, when I turn it off manually and starts it again it happens again, but it never restarts twice. what's the problem then and how do I fix it?

nukemaster · Oct 18, 2017

You say the system is not overheating.

What are the temperatures like?

Naipross · Oct 18, 2017

If I can play a more demanding game my temperatures should be higher when I play that and it doesn't crash when I play that, only when I play csgo it crashes and there's like no software that reads the fm2+ socket correct. one says 20 another says 85, so I can't know what my cpu temps are, in bios they're 40 degrees celcius. Max temps on amd 870k is 72.2 degrees celcius

nukemaster · Oct 18, 2017

Did your board come with software to monitor temperatures.

A hard off does sound like a safety thing. I have seen driver/software issues cause similar issues in the past however.

Naipross · Oct 18, 2017

no I don't think it came with a software.

nukemaster · Oct 18, 2017

Your boards support document seems to indicate it has ASUS AI Suite 3 support.

I would try that. It is on the CD or Asus support site.

James Mason · Oct 18, 2017

The event viewer error is just saying the PC lost power suddenly, not necessarily the PSUs fault. that happens whenever the system "crashes."

Naipross · Oct 19, 2017

can the cpu cause this problem because when I overclocked it. There was nothing to control the voltages with so can it be because the voltages is on auto? there was cpu offset voltages and that was the only thing with voltages.

nukemaster · Oct 19, 2017

Auto may increase voltage quite a bit when overclocking(to attempt to improve stability, but at the cost of higher temperatures).

Offset could be better(offset also allows power savings to function). It takes some time to lock in an offset, but can be worth it.

Any luck with AI suite?

Naipross · Oct 19, 2017

what should I use the asus AI suite for?

Naipross · Oct 19, 2017

Asus AI suite says that the cpu temp are 45°c and the MB is 35°c Idle. under stress test 50°c cpu and 35°c MB just ran the stress test for 5mins. When idle it says that the cpu runs 100%/4400MHz and 1.440V. I only have Cpu frequency, voltages, temperature and fans.

nukemaster · Oct 19, 2017

Well that should indicate that your cpu temperatures should be ok. While AI may monitor a board sensor instead of a on cpu thermal sensor, you still seem to be well in the green if you only hit 50c. I would run it when gaming to see if it gets any hotter(check in from time to time.

The 100% load at idle does not seem normal however. Does the task manager show anything taking all your cpu cycles?

Naipross · Oct 19, 2017

ok I'll check it when I game next time. In the task manager it says that the cpu only is 30% watching youtube 1080p. totally idle it's around 10%. It just shows 100% in asus AI suite. What could cause my pc to crash then if my cpu is alright and everything else is fine?

nukemaster · Oct 19, 2017

Software or drivers.

Some monitoring software can cause such issues(I remember seeing it with speedfan for instance in the past).

Other hardware. Your restarts do not have any blue screen message right?

If you run something like Prime95(may have to leave one core free for the video stress test) and a video stress test together do you crash? This should be much more demanding than CS:GO

Naipross · Oct 19, 2017

Just ran prime95 and valley benchmark at the same time without it crashing. The things is it only crashes once per boot. so when I manually shut it down it crashes next time i start it but it never crashes when it already have crashed once.

Naipross · Oct 19, 2017

can this happen if I haven't updated windows because I haven't upgraded to windows 10 creators update last time i tried i got a totally grey screen and couldn't do anything I restarted the pc and it did like a windows 10 recovery or something don't really remember. I've tried upgrading it multiple times but the same thing happened.

nukemaster · Oct 19, 2017

Older software may have some bugs.

You say it fixes once it crashes? Do you have any overclock active? Maybe on reset it goes into some kind of safe settings.

Naipross · Oct 20, 2017

I have my cpu over clocked to 4.4GHz from 3.9 and on the gpu I've got +155MHz coreclock and +200MHz memoryclock. yes it fixes once it crashes. I did run Prime95 and valley today again and now the pc just freezed and i couldn't do anything but isn't that something that could happen if I stress cpu and gpu at the same time?

nukemaster · Oct 20, 2017

Stressing both gpu and cpu at the same time is exactly what some games do.

I recommend trying stock to see if it happens. It may very well just be an unstable overclock. The overclock also adds more power consumption to a system.

Naipross · Oct 21, 2017

It didn't happen when I had stock speed. so how do I get a stable overclock now?

nukemaster · Oct 21, 2017

Try the video card first then the cpu. Maybe only one is unstable.

Try the cpu at lower clock speeds. Not all can clock as good.

You may also be able to try offsets to see if they are better(very small amounts. do not go crazy).

When overclocking, power consumption does become more of an issue.
