Solved

I need some help with my PSU! :)

So first off my system:

MOBO: Z77X-D3H
CPU: i5 3570k
GPU: Msi 660ti
RAM: 2x4gb Patriot Ram @1600mhz
PSU: Corsair CX 500 Watt 80 Plus


So everyone is telling me the psu is too small for the overclocking I am doing, but here's the kicker. When ever I run a PSU calculator test my system always is at like 380 watts. I have my cpu overclock with volts in and still all test are like 380 watts.

Here is the settings I use: (down the settings in order)
1 physical CPU
Regular - Desktop Mobo

Intel
LGA 1155
Intel core i5 3570k
100% TDP (I set every power setting to 100% just to get full maxes)
Overclock settings:
4.6ghz
1.3v

2 Sticks of DDR3

NVIDIA
1xGTX 660ti

1x5400rpm

No SSD

No Drives (No DVD, blu-Ray, CD, Tape, Floppy; nothing)

No PCI Cards

No Usbs

No Firewire

No Fan Controller, or Front Bay

No Cold Cathodes (I dont even know what that is lol)

Fans:
2x120mm Regular
2x120mm LED

No Water Cooling or Kits (I have a Hyper 212 Evo+; only uses the fans)

System Load: 100%

Capacitor Aging: 10% (new psu, but will be keeping it long)


The 12v rail on my PSU puts out 453 watts, which means I have about 50 watts of power left (Keep in mind its not the full 500 watts; 80 plus though)

Is 50 watts enough to overclock my 660ti a little? And how much do you think I could?

Also Core Temp shows my cpu using 60 watts @100% load @4.6ghz but the psu calculator says 113 watts??

  1. Best answer
    The maximum power of the 660 ti is 150w(nvidia site), the cx 500w will do for it even oc+ rest of components, though, there're better psus, it will do, it will not reach 400w max load, your system, that's with the cpu and 660 ti oc, etc.
