I just built a great system, updated every piece of hardware with the latest possible drivers, got all of the windows updates, and I'm occasionally getting random shutdowns (no bsod, no errors. as if I just unplugged the computer) with a restart automatically following shortly after. My full system specs:
mobo: asrock z68 pro
cpu: i5 2500k (turbo boost limited to 4.2 ghz, idles at 35c, never goes over 90c on load)
gpu: gtx 560 ti (oced very slightly while playing games)
ram: G.SKILL Ripjaws X Series 8GB
sound card: ASUS XONAR DG 5.1
hdd: Seagate Barracuda ST31000524AS 1TB 7200 RPM 32MB Cache SATA 6.0Gb/s
psu: Rosewill Green Series RG700-S12 700W
I don't think my cpu is overheating. I've never had a shutdown while playing games yet (I built the system about 3 days ago by the way). It seems that I shutdown at random times. I shutdown twice while screensharing on skype, when I was playing a flash game on the internet, when I was editing some hd footage, browsing the internet, downloading a game on steam, and other random times. Should I return this PSU and get a better one (if the problem is with the PSU)? Thanks. I really feel like I skimped out on the PSU. I regret it.
All of my temps are normal but I don't know much about the voltages. How can I know if they're abnormal? And no, I do not have an extra PSU. Also, what determines if a PSU is low-end or high-end? I might just have this PSU returned and buy a better one.
The shutdowns are pretty rare now. If it bothers me more I guess I'll have it exchanged for a better one. But you guys are sure that the issue is with the PSU and nothing else right? I do not know how nor do I have the tools to test the voltage of the PSU though.
A GeForce GTX 560 Ti has a graphics card power of 170 Watts. This means that the graphics card itself may draw up to 14.2 Amps from the +12 Volt rail.
For a single GeForce GTX 560 Ti graphics card system NVIDIA recommends a power supply with 500 Watts or greater with a +12 Volt continuous current rating of 30 Amps and with at least two 6-pin PCI Express supplementary power connectors.
The Corsair Enthusiast Series TX650 V2 (CMPSU-650TXV2) with its +12 Volt continuous current rating of 53 Amps is way more than enough to power your single GeForce GTX 560 Ti graphics card system with plenty in reserve for overclocking the CPU and GPU and the addition of more peripherals.
