Corsair vs450 power supply sufficient enough?

[Waseni]

Hi.
I've build my first pc 9 months from now and to be honest it gives me quite a trouble.

Components are :
MB: Asus M5A78L-M LE/USB 3.0
CPU: AMD FX-6300
GPU: ASUS RADEON RX460 DUAL 2GB OC
RAM: 2X 4GB KINGSTON HYPERX FURY 1866 mhz
SSD: KINGSTON 120 GB
HD: 1000.0 GB SEAGATE Barracuda Guardia 7.2K rpm
Power supply : 450W, CORSAIR VS series VS450
Water cooling : ARCTIC COOLING Liquid Freezer 240

It worked all well for first month or two but then I started to have crashes with my gpu drivers which later became a bit bigger issue because my pc had sudden restarts.
Restarts are gone now that i lowered my gpu voltage.CPU aren't stable as it used to be now it has sudden drops from my 4.1 ghz oc to 3 ghz if i don't turn on and off turbo core in amd overdrive.
And today i noticed in my bios that my cpu voltage are marked as yellow on 1.261 volts .I'm sure that before it was entering yellow zone at 1.38 volts and also sometimes some weird cracking noise comes from my psu ,it's not frequent but it happens.What could that mean?
Should I change my power supply?

All the things you said are pointing to a power supply issue. If you can, borrow a different power supply and check the voltages, but I'm 99% sure the PSU is the issue.
From what I remember the VS series from Corsair is not regarded as a good PSU, also any overclocking on that particular board is sure to stress it out so that may also have caused issues.

450 W seems sufficient ,but if you begin having problems on a new system ,that are indicative of a bad power supply, it wouldn't matter if it was 1000 W because it could be a bad unit

This screams unstable overclock to me...CPU clocks do not drop because of a bad PSU or lack of power. There isn't really a 'brown out'. Its on and works and providing enough voltage, or it doesn't.

You are overclocking a hex core CPU on a 3+1 phase motherboard... I'm going to look there before the PSU personally.

Tough call here without swapping out honestly.

On VRMs without a heatsink no less but, restarting under load is definitely a PSU failure characteristic in most cases. Problem is that it realistically could be both. Even if it is the PSU, the board is likely going to throttle due to VRM temps. It's also worth noting that hot VRMs are less efficient which should be factored in. Either way, I think overclocking with this setup is rather unwise.

Guys what you say on these heatsinks for vrm? https://www.amazon.com/Enzotech-Mosfet-Passive-Copper-10-pack/dp/B004CL89D8
Also I'd like to take another power supply.Is it possible to find one that could last for few years and still be adequate for newer systems?
This way seems cheaper than buying new motherboard and even more when there is am4 on the market ....My oc is stable as long as there is 120 mm fan blowing at vrms.Without that it's imposible to maintain 4.1 ghz frequency even on 1.26 voltage.Once Mobo temp reaches 50 celsius it trottle back at 1.4 and back up once it cools down

 

[EarthDog]

650w evga g2 or g3 is plenty for any single cpu and gpu overclocked and allow plenty of headroom. Hell, with a 1080 or lower, you could sli on 650w.

Looks like youve answered your own question. When did you try the fan?

That motherboard is a bottom Barrel motherboard for Asus at this point I would get a 520 Watt seasonic and then slap fans on the Vrms. Otherwise you need to get a 990fx base motherboard from Asus the Sabertooth R 2.0 or 3.0, Crosshair 5, AsRock 990FX Extreme 4 or 6, Gigabyte 990FX UD3 or UD5- the Revision that @manofthem or @ThE_MaD_ShOt has

With what you said on noise and instability, have the motherboard tested if possible.

Otherwise replace both parts to avoid any other system damages.

 

[Jetster]

The VS power supply are bottom tier but still work just fine. Ive done two builds with no issues one was the vs450 the other vs550

Well, it still rolls back at 3 ghz under prime95 if i don't turn on and off turbo core in amd overdrive .I tryed fan when i first got my current oc.Prime95 runed 10 hrs stable that way.

Sorry I'm not sure what you mean by "have the motherboard tested it possible."

PSU can handle,even if is low rating/cheap,problem is with mobo/vcore/phases and cooling

Advise: Keep it default and see how is working or change psu/mobo/cpu for optimal performance,be aware that VS are not made for OC and stable amps.

could amps be reason behind my gpu driver crashes?it works well only if i undervolt from default 1120 volts to 1022 or when core frequency is reduced by 10% which makes it run at around 990 volts based on gpu-z readings
also it says that pcie power outpu is 48 watts on gpu-z.could that be an issue?even tho ppl say that PCIe 2.0 x16 should be fine with 75 watt gpu
regarding cpu it runs at almost default voltage ranging between 1.248 -1.272 volts with average of 1.26 volts. default settings with amd turbo core pulls 1.4 volts and without turbo core it's not much less than my oc voltage.maybe i could lower it a bit but i doubt it would go below 1.2v

 

[ASOT]

Stable amp and voltage is esential for cpu/gpu or else.. swap the psu and try

You are all over the place...

1. If pointing a fan at the vrm allows your clocks to stay high, then its obvious they need cooled and that is at least part of the issue.
2. Put cpu to stock and run gpu...does the driver still crash?
3. Put everything at stock and test...does it still crash?
4. As was said earlier, its likely one or the other. Because the motherboard isnt made for overclocking, we have no idea what is causing crashing under load. It could be the psu, it then that motherboard is also weak and may still throttle...you may buy another board amd the psu is bad.
5. Test the rails with a multimeter...

6. Amps matter, but the vs has enough to power that system, especially at stock.

Thank you guys for all the replys.I appreciate your time.
It helped me a lot and i made the choice.
Cheers!

 

[EarthDog]

And that choice was...........what?

 

[Waseni]

I will take better psu since it's component that could be used in future upgrades.I took look at 650w evga g3 and ppl complain about fan noise,probably better to look further. I'll also take this cooper mosfet heatsinks : https://www.amazon.com/Enzotech-Mosfet-Passive-Copper-10-pack/dp/B004CL89D8
Going to take risk with that so i can utilize more of my water cooling for a bit higher oc.
New mobo is just not an option since i don't intend to stick with am3+ when new motherboards are on the market.Thought to myself that it would be better to invest money from new am3+ mobo to better psu.

 

[EarthDog]

Lol, no fan noise on there. It has an eco mode. The fan wont even spin up with your pc man!

Edit: 750w has eco mode.. oops.. but i cant hear it all when it spins up....under full load.

Not sure if the psu will resolve your issues...but good to get those heatsinks and some thin thermal pads... it can only help until your mobo pops!

 

[Waseni]

i hope it won't pop for another year or two I' ll try to squeeze max under 1.4 volts
should grant me 4.3 ghz at least

 

[EarthDog]

I wish you the best of luck, because, you will need it.

I honestly think a new board is worth it if you are going to keep it for a "year or two".

Sorry I'm not sure what you mean by "have the motherboard tested it possible."

Take it to a shop and have them test your motherbiard, cpu and psu with their known good parts, process of elimination.
