Cyberpower pc questions

Jan 15, 2017 1:51PM PST

Guys I need some help with a gaming computer. The computer is a Cyberpower pc (raid max case). The only thing I can find with the cyberpower name on. The motherboard is a Msi 760 Gm-P34 (fx), Video Card is a Msi (Nvidia George Force Gt 720), Psu is a Thermaltake Tr2 430 watt (brand new), with 8gb of ddr3 1600 Ram (8gb total), and a 1tb hdd. My problem is this thought the motherboard or cpu went bad but it was a bad power supply by process of elimination. I have checked all the other components out and everything checks out good now, and I can actually get the computer to boot up now, but here are my issues I am trying to solve now biggest one is that it randomly shuts down like the power has been cut, sometimes it will stay running for an hour or 2 and sometimes it is a matter of just a couple minutes and it shuts down, and my other issue is this I can't get into the bios at the start up screen it is booting up in AHCI mode and it gives me no option to go to bios setup I would really like to do a clean install of Windows 10 on this computer but need to be able to change the boot order in able to do it. Any help or advice in this situation would be very much appreciated and thank you in advance for the help.

That PSU is awful.
Jan 15, 2017 1:54PM PST

"12V1@18A, +12V2@17A" so it's split rail and could be easy to overload a rail and shutdown.

I don't think a Windows reload is needed here.

This was the Psu recommended
Jan 15, 2017 2:34PM PST

the Psu is the one that was recommended to me at the parts store here they assured me that it would run it with no issues if it is not powerful enough what should I try this is for a friend of mines son so want to make sure it is reliable I don't understand though how the power supply again is the issue I have a gateway desktop that has the same ram and same processor but a different video card and it runs perfectly if I pull the video card on the cyberpower pc and use the on board via instead will this issue go away

The pull the graphics card test is telling you
Jan 15, 2017 2:37PM PST

There's a power issue. The PSU you listed is not recommended by most folk here. We stick to single rail models to avoid rail balance and overload issues. The symptoms and your test points to a poor PSU.

confused last post
Jan 15, 2017 5:04PM PST

sorry I must have got something mixed up in that last post with the cyberpower pc it has the same power problem whether you are using the Nvidia video card or the on board video in the motherboard I was referring to my gateway running properly on a 400 watt power supply

Shutdown
Jan 15, 2017 5:17PM PST

Get a can of compressed air and a small brush.
Take the side panel off and give the innards a good cleaning.
Pay attention to the heatsinks and fans.
Power it up and verify all the fans function.
Leave the side panel off and test.

thank yo
Jan 15, 2017 5:31PM PST

ok bob I will try that and see if it helps

If the computer is trying to pull too much power can you guys please recommend a good video card that will work with this motherboard and Psu that has an hdmi port

thank you again

need some sound advice
Jan 16, 2017 6:36AM PST

ok with the equipment I listed in my first post to start this thread can anyone help me with figuring out 1 of 2 things

1. A good replacement motherboard that has hdmi on the board

2. A video card that has hdmi that doesn't require so much power to run so I can continue to use the 430 watt psu

That's the last thing you want to change.

Since the power issue happens with and without the gpu I would not suspect the gpu.

You did not say if you did the cleaning/fan check and the cover off test.
While your in there verify the cpu hsf is firmly attached.

Lowest power GPU?
Jan 16, 2017 11:02AM PST

GeForce 7300 GS is about 16 Watts.

Your current GPU is about 19 Watts.

This may or may not help get by with such an awful PSU. In fact a good PSU may be cheaper.

work in progress

I am in the processs of breaking this thing all the way down to nothing have pulled everything out of the case and thourally cleaning it all realized last night that the cpu was installed under the heatsink whit no thermal compound. (asked owner if he had ever disassembled it and said no) so I am guessing it was shipped to him this way I don't know how it hasn't fried the cpu already but picking up some compound for it today for reassembly and testing I will let you know the results.

can you though please explain to me what is so cheap about this psu unit I am a true believer in taking no short cuts and the guy at the computer shop where it was purchased assured me that it would fit my needs and was of good quality so please help me understand why this was a bad decision to purchase it

Good to read you found the compound issue.
Jan 16, 2017 12:32PM PST

As to the PSU, the +12V rails are pretty low powered. Now the total Watts looks fine but the split rail means that we can't be sure if we are pushing a rail too hard. While this PSU might do, the troubles point to a faulting or overtaxed PSU.

I guess I could write more but hope your compound heatsink work helps.

Why the PSU was a bad decision is that a single rail would have removed the need to know what's on each rail, moving parts from one rail to the next. That sort of work is for engineers. I don't know your electronics skill level. Here that would take me marking which plugs have which rail then using a current loop meter to see how much each connection is pulling. All that goes onto paper so I can think over how to reduce the higher load on one rail.

Most owners are not into that work or don't understand what I wrote because well, why would folk know about Amperes, Rails and Watts?

thank you for clarifying that
Jan 16, 2017 2:41PM PST

I was wondering when I was installing the Psu why all the plugs were marked with different designations I can write down the numbers on the plugs and post them when I get home and that might help I do know for sure at this point that 1 cable goes to the dvd and the other goes to the hdd because that is all that is installed in this pc at this point the only other connections are the two motherboard connections

Psu
Jan 16, 2017 7:26PM PST

It would have been better to have a single rail unit just to keep life simple.
However in your case I doubt it matters.

Let's say everything is connected to rail #1.

Rough numbers.
Rail #1.....215w

The load.
Cpu...................100w
Gpu....................25w
Hdd/cd/fans.....30w
Looks like 155w.

If that psu can deliver on the rated specs your not close to overload.
Looks to be about 70%.

Toms tested a lot of supplies
Jan 16, 2017 9:55PM PST

And found many to fail close to the ratings. The PSU is suspect but what's next is even more time and money. Motherboard and other parts.

I start with a good PSU so I never worry. This one if on my PC would be gone.

Thank You Everybody

I just wanted to say thank you to everyone who gave me advice on this situation. I went through this computer from front to back, cleaned everything reapplied thermal compound to the Cpu, made a few changes to the bios, and did a fresh install of Windows 10 it is now on its 2nd day of my test running since yesterday with no shut downs.

Cpu Temp. 42° C
GPU Temp. 45° C

Just a quick note this tr2 psu seems to be fine with this system The AMD fx6300 is 3.5 ghz and it is clocking right now at roughly 3.8 with these Temps if everything stays the way they are till tomorrow gonna start running some gaming scenarios on it and see what happens.

I think the biggest factor in it shutting down before I did this work on it was the Cpu Temp due to no thermal compound on it.
