Potential PSU problem?

[dboy87]

Hi,
I have a rig that is build up of following parts:

3.4 GHz Intel i7 4770 (not K)
Gigabyte 4 GB GTX 970
16 GB 1600 MHz Corsair Vengeance RAM
256 GB Samsung SSD
4 TB Seagate SSHD
600W CoolerMaster PSU

The problem is sometimes I get random flickering and beep sound along with the voulume icon being displayed, usually under heavy load I think. Another problem is that my 4 TB SSHD randomly stops responding and starts disappearing from my SYstem Volume information. SOmetimes even files gets corrupted on it. But it works fine if I try to access it via external USB connector and power supply. I even tried by changing the SATA ports and cables but the problem persists.

Could these be because of my PSU? Do you think its enough for my PC or should I upgrade?

Here's the screenshot from OCCT power supply test.

The HWMonitor engine, that is being used by OCCT, that displays the sensor readings for voltages is garbage.

If your +12V rail was really operating at +3.21V, +5V rail at +3.46V and +3.3V at +1.12V as reported then your system wouldn't even turn on.

What is the exact Cooler Master model number for the PSU?

My PSU model is cooler master RS-600-PCAR-E3.

My PSU model is cooler master RS-600-PCAR-E3.

That's the Cooler Master eXtreme Power Plus 600W with a liar label. It's made by Seventeam. It can't even put out 480W when new without the +12V rails voltage dropping out of spec. It should've been labelled as a 450W PSU. As the PSU ages the capacity will be reduced and the system that it is being used in will become unstable.

You can try troubleshooting with a better quality PSU.

Thanks, can you recommended me a good one, preferably a cooler master one as this is the brand most readily available in my city?

I have no idea which Cooler Master models are available to you or what your budget limit is.

Cooler Master has a lot of PSUs that I would never recommend. These are the only ones I would even consider recommending:

V550 Semi-Modular (RS-550-AMAA-G1)
V550W (RS-550-AFBA-G1) <==== Full Modular

System Power Supply Requirements for a single NVIDIA Reference Design GeForce GTX 970
• NVIDIA specifies a minimum of a 500 Watt or greater system power supply. (Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz 130 Watt TDP processor.)
• the system power supply must also have a maximum combined +12 Volt continuous current rating of 35 Amps or greater
• the system power supply should also have at least two 75-Watt 6-pin PCI Express supplementary power connectors. There are some non-reference design cards that require one 75-Watt 6-pin and one 150-Watt 8-pin PCI Express supplementary power connectors or just one 150-Watt 8-pin PCI Express supplementary power connector or two 150-Watt 8-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.
