Hi guys I just want to ask if my PSU can handle overclocking of cpu or gpu or maybe both?

Specs:
Intel i7-4790K
MSI GTX760 TW
MSI z97 Gaming-5 mobo
Seasonic 520W
8gb 1600mhz ram


A response would be much appreciated

Thanks!

Seasonic is very solid brand. You will not have any problems.

Even the power rating is low? "520w"

will it support the cpu and gpu if I overclock them?

Thanks for the reply :)

Get a decent 650w if you want to overclock.

Yeah a gtx 760 is a 170w card plus processor/motherboard 120W Hard drive, Ram, DVD .. Well I believe you are likely already pushing 460+W and even a mild overclock could possibly make your rig unstable. I would suggest at least a quality 600W before overclocking, something else to consider is if you are going to upgrade your power sully you might consider upgrading to enable yourself to go sli(so you don't have to upgrade your Power Supply again later) that would however require a good 800w+ power supply. Hope this helps have a great day.

The power supply also isn't Haswell compatible.

I was fairly certain that Compatibility in things like that really meant nothing, as long as it supply's enough power to the correct components that is all that matters.

When an Intel Core (i3, i5, i7) processor is idle, it goes into a sleep state that requires less power than when the CPU is active. Since the motherboard voltage regulation modules that provide power to the CPU gets their power from the power supply's +12V rail, these sleep states can dramatically reduce the load on the power supply's +12V rail.

According to Intel's presentation at IDF, the new Haswell processors enter a sleep state called C7 that can drop processor power usage as low as 0.05A. Even if the sleeping CPU is the only load on the +12V rail, most power supplies can handle a load this low. The potential problem comes up when there is still a substantial load on the power supply's non-primary rails (the +3.3V and +5V). If the load on these non-primary rails are above a certain threshold (which varies by PSU), the +12V can go out of spec (voltages greater than +12.6V). If the +12V is out of spec when the motherboard comes out of the sleep state, the PSU's protection may prevent the PSU from running and will cause the power supply to "latch off". This will require the user to cycle the power on their power supply using the power switch on the back of the unit.

While we are still working with Intel on the details of the testing methodology they use to check PSUs for Haswell compatibility, it is already known that a power supply that uses DC to DC for the non-primary rails (the +3.3V and +5V) will not have an issue with the new low power sleep states. This is because a DC to DC buck converter is used to convert +12V to +3.3V and +5V. This means that no matter what load the CPU puts on the power supply, there will always be a load on the +12V because the +12V is required to provide power to +3.3V and +5V.

Corsair utilizes this DC to DC technology in most of their power supplies. Starting with the CX750 and CX750M and moving all of the way through the GS Series, TX and TX-M Series, the HX Series, both the AX Series Gold and AX Series Platinum, and the new AXi Series. So whatever your budget, if you choose Intel's new Haswell processor and wish to utilize the new, low power C7 sleep state, Corsair has a power supply for you.

I see, well that makes since then, as with all the system's that we build we disable C7, speed step, Etc to increase performance on our machines and remove the lag of processor spooling.

I just purchased an 850watt PSU for 30quid.. its heavy.. the heavier the better.. ring your local shop and ask them if they have an deals on..
