(Help) What PSU i should grab for my PC.

[melev2910]

Hello guys.
I was used Corsair CX750M, but now it doesn't work properly.
When I use my pc about 30minutes till 1 hours. My PC got hang, blank monitor and led keyboard mouse turn off then i can't force shutdown my pc. I need to unplug cable power to turn of my PC.
I ask my friend he said my PC temp all normal, and it seems my PSU can't handle my pc again, so i need to grab the new one. I need help for choosing new PSU for my PC.

Here is my spec :
Procie Amd FX8350
VGA GTX970 Jetsteam
RAM 2 x 8 VGEN 1600mhz ddr3
1TB Seagate WDC blue.

Is the 650W PSU min req for my PC build sir?
Is it better the 650W Gold or the 550W Titainium sir?

 

[Dark Lord of Tech]

A 550W can run those specs.

 

[melev2910]

so sir its ok even i grab the 550W Gold PSU from Seasonic? or prefer the 650W Gold? I don't plant at overclocking or even using 2 GPUs, coz im just a beginner.

It very well might not even be the PSU that is your problem. In fact, I am in pretty good belief it might be the motherboard.

I recommended that particular 650w psu only because it was on sale for a great price. That sale is now over so I change my recommendation to this-

turkey has a good point though. You should always find out what the problem is before you go spending money. Have you tried troubleshooting it at all? Take the 970 out and see if it runs correctly.

What motherboard are you using?

 

[Dark Lord of Tech]

To properly diagnose it never hurts to get a good reliable PSU , CX750M is not a good one that's for sure.

 

[melev2910]

I asked my friend, he said its will be 2 option motherboard or psu. I check my motherboard, its look all ok no damage and all capasitors look good. So i think its PSU problem, my CX750 also a replacement PSU from distributor. I have used it about 2 week and the problem come. I have tried to remove gtx970 and using onboard vga driver. Cpu temp look normal, but when i try to run Bluray movie it hang again even without gtx970. When my cpu hang, i can't even force shutdown my cpu.
So guys is it a PSU problem or motherboard? How to check if my motherboard ok or not?

 

[melev2910]

My mother board is Asus M5A78L/ USB3.0
I used it since August 2013

 

[melev2910]

Which one better Seasonic G650 or Using Superflower Leadex Gold 550? that two price is balance.
And how about Superflower 650W Platinum King? its Platinum but the price is lower than G650 and Leadex G550.

First you need to describe what "My PC got hang, blank monitor" means. Blank as in black? Blank as in frozen? Is there video output? No video output (no signal?)

 

[melev2910]

Yea, it just happens like that. CPU still on, all fans at case working. But monitor doesn't display anything (no signal)
I used mouse and keyboard with LED, with USB port connector.
When it happens, all LED at keyboard and mouse off, even numlock not working.
Power LED at case on, But Process LED isn't blinking even just once. When i try to force shutdown (holding power button at case), it doesn't work.
I need to unplug the power cable to make it off.
Then i try to remove my gtx970, but this thing still happen.
This is my 1st time with problem like this, i was asked my friend then he said it may be PSU prob.
How about ur thinking sir?

 

[turkey3_scratch]

I think it's the motherboard.

 

[melev2910]

But sir, when i plug again the power cable, then turn on my cpu, its beep and then pc run normally, i try play games, play movies etc.
But about 10 minutes or more it hang again.
The last try, when i try game with my gtx970, i got very low fps with the game. back when my pc normal its ok even with ultra setting.
So how to check my motherboard healthy or not sir? any idea? help me XD

What kind of cpu cooler are using? How are your cpu clock speeds during gaming?

 

[melev2910]

CPU cooler, deepcool ganmaxxx 400, clockspeed cpu 4Ghz, i'm not using OC coz im beginner sir.

 

[CTurbo]

I meant what are you actual clock speeds during gaming particularly when the issues occur.

 

[melev2910]

I think it's the motherboard.

sir why u believe its motherboard problem? i have bought a new PSU. I try to run my PC but 1 hours latter problems still come. I'm really crazy with this problem.

 

[melev2910]

I meant what are you actual clock speeds during gaming particularly when the issues occur.

Already a long time in use,did you use it with a different cpu before? If so which one and do you still have it in that case? Could test with it if still having it.

Did you ever update the bios?

 

[CTurbo]

We told you to properly diagnose the problem before spending money.

What psu did you buy?

 

[melev2910]

Sorry guys its been a while, i'm really mad with my PC problem.
And as the result 3 days ago, i'm on gamble spending my money again to pick a new motherboard with the same type.
and then right now, my PC is working well again like before. SO the MAIN problem is MY Motherboard.
Thank all, u guys really help a lot.
