Title. When playing games, my psu sometimes starts to buzz, and then it goes away for a few second, until i encounter some load in game. More buzzing, but louder and BAM, pc restarts. This is not just a squealing capacitor or so, i mean, my pc just resets. Quite annoying. :/

As you can read in my sig it's a 400cx Corsair, rest of my specs are in my sig. Bad psu? Too much load? Could it help if i put my motherboard and harddisk on some old psu and use the 400cx for my gpu or so?

I'm really depressed. :bawl:

400W isn't a huge amount, so it's possible it's under too much load.

Other than that, check it's still mounted properly and not shaking about, and it's clean. Dust build up may cause an overheat.

It could be yes, but on the other side, lots of people said that it should work flawlessly.

I run caseless, and there is not a gram of dust on my components. Also, a loose psu shouldn't make a pc restart. (Since the buzzing is parallel with the restarts, a loose psu wouldn't make much sense)

Then try a new PSU if you're convinced it's not anything else.

No, i have no money, or at least not for a worthy upgrade. If i upgrade, i'm getting 650tx or 750tx, not a 550w for 75€ where you end doing nothing more than just a gts250 and the current system. I don't have the money for a future proof solution.

Is there any other fix or so?

Nothing else I can think of. Not still under warranty I assume?

It's only 5-6 months old and i even have the box and such, dunno how RMA works though.

First, i want to make sure a RMA will fix it and not just the fact that's it's only 400watt and is dying under the load. A few weeks without pc will kill me, and if it's a useless RMA... And i have to pay shipping to the US, and that's half the price of a psu, so better not.

I suppose you could start HW monitor, and give your CPU/GPU a stress test simultaneously, watching temps and voltages during this time. It's very likely that it's the PSU though. I run a 500 watt (kow thinks it's crap) ULTRA PSU on a system with half your power, and it runs fine, though I'm weary of all-out upgrading with it.
