PC Shutting Down

[jwmachon]

Hi,

This is my system specs

AMD x4 960T 3.0Ghz Processor
Hyper 212 evo cooler
GTX 560 TI GPU
Windows 7 Ultimate
various usb sources keyboard mouse, 360 controller, joystick
pci Wireless card
EZCOOL 650W Power supply

Here is my problem

Overclocking the cpu upto 3.4ghz is not a problem on stress tests however if i go higer or increase the voltage a bit the pc shuts down completely just turns of no screens or anything

Core temps are fine

Does this sound like a psu not good enough

Thanks

Jonny

PSU is a possibility - it is a low end power supply, and even if it is rated at 650W, it will probably be far below that. We here recommend to get quality PSUs because it is a very good investment.

edit: This also does not necessarily mean you need more than 650W - with that build you can also get away with a high quality 500W PSU. But 600W is a good point to start if you want to have some headroom.

what else is worth checking ive tried different combinations but it always happpens when i try above 3.4 or increase voltage

thanks

first thing I notice is this:
http://www.amazon.co.uk/EZCOOL-650W-.../dp/B0010YLGZI
4 for 4 sayin steer clear.

2nd thing I notice is this:
+3.3V 35A; +5V 38A;+12V 38A
that much power on the lower voltage tells you it is an old design.

third:
For Socket 775; AM2; and all backward compatible CPU’s

I'm gonna go out on a limb here and say that PSU has outworn its welcome and its time you invest in a good unit.

Second EZCOOL question this week, same answer. It's JUNK.

I'm surprised that EZCool power supplies are still on the market. Could the EZCool 650w model produce 300w without blowing up? Probably not. I would not attempt to overclock anything in that system until you install a safe and reliable PSU. EZCool is a disaster waiting to happen - killing your mobo, ram, and video card as it releases the magic smoke.
