OK guys, I need some help to localize what my problem may be.
Recently, my monitor keep crapping on me. I linked it to my computer both with DVI and VGA cables but the problem is the same : at some point, when I play a game or a Youtube video and try to go in fullscreen mode, the screen goes black, sound stops and I get this strange "D-SUB GESTION ALIM" message (sorry, in english it means "power management")

Now, I think many things could be the source of errors :
GPU : Gainward GeForce GTX 560 Ti Golden Sample
GPU Clockspeed : 900 Mhz
Memory Clockspeed : 2100 Mhz
This thing might be my nemesis. It can consume up to
395 W in busy mode and as we'll see, my PSU is not the best ever. Roughly, the consumption is the same as a ASUS GTX 580.
PSU : Cooler Master GX Series PSU - 550 Watt
Probably what makes me cringe (?) 550 W is probably seen in GAF as a blasphemy but I decided to give it a serious try on Cooler Master CPU Power Calculator. As mentioned above, I filled the GPU line with a GTX 580 just to be sure that I'll get a strict minimum wattage result.
The outcome :
This is exactly the PSU I am using. But will this really be sufficient with a webcam and an X360 controller in addition ? I don't doubt it, but I can't exclude the possibility for it to be overloaded.
Monitor : LG - Flatron E3450V-PN
Believe it or not, this guy (who has the same problem as me) posted a video with what seems to be my monitor :

But I didn't hear anything crazy about this monitor.
Cables :regular shit provided by LG
So GAF, do you think I have a deeper problem that what I listed here ? Please, help me to refine the problem. I can't game, that's as simple as that and I bought this machine in order to be able to play upcoming games + emulation. Talk about a bummer. Also, I can use my computer for normal task easily. It seems that under big load, like Youtube fullscreen 1080p, Metroid Prime Intro scene, the monitor just gives up. I want to know what's happenning. Thanks in advance.
