PSU Power surge Asus shutdown

[sisi lee evans]

Hi just finished my first new build with the following specs

CPU
Intel Core i3 3220 (3.3 Ghz) Ivy Bridge
PSU
Corsair GS Series Alimentation pour PC ATX 600 W
RAM
Mémoire Corsair CMX8GX3M2A1333C9 (2x4Go DDR3 1333 PC10600)
MOBO
Asus P8B75-M LX Carte mère Micro ATX Intel Socket 1155
VIDEO CARD
Sapphire 11200-14-20G Carte graphique AMD Radeon HD 7850 920 Mhz 2 Go PCI-Express 16
HARD DRIVES
Western Digital WD5000AAKX WD Blue Desktop Disque dur interne 3,5" SATA III 7200 tours/min 500 Go
SSD Intel 80g

I'm occasional getting computer shutdowns
"ASUS Power surge detected - computer shut down to protect etc"
when the system is idle or running small programs like word (but strangely enough not when gaming CS GO etc)

Here are my questions.
Q1) Is this happening because the PSU is not powerful enough (I checked forums before the build and people said it would be fine)
Q2) Could this be happening due to home power supply being unstable?
Q3) I've downloaded HWMonitor to check for voltage spikes but what should I be looking for to know if something is wrong?
Q4)This started happening after I installed the vid card so I suspect it's because the PSU is not powerful enough but before I fork out for a new one is there anything I can do to affirm that this is the problem and not something else?

I'm having the same problem atm. You found out what happened?

The consensus with this app is that its too sensitive. You can shut it off via the BIOS.
