BeQuiet Squeal

[F2kSel]

If I were returning a PSU back to Be Quiet, I would go and use their PSU calculator first and make up a rig that draws less power than your current one so that they cant turn round and tell you that the PSU isn't up to the job...

Their PSU calculator is well dodgy, it claims that 1 GTX280 will draw 700w of power itself!!!

I just bought the 850w Dark Power Pro myself, and since purchasing I have noticed a couple of threads about people complaining about their PSU's... I hope my one doesn't go bad!!!

He shouldn't have to do any of that it if his rig is using less power than it says and according to all the people here that's the case.

Even if it was using more juice I really don't think it should go bang, I'm sure there would be a fuse or thermal cutout that should work if over loaded.

Yup, blowing up is different to not being able to support a PC under full load.

I've had the PC overclocked running prime, ATI artifact checker on and 2 instances of that HD lighting app thingy to try and force the GPU to crash (been getting pink screens of death in L4D/Fallout) and the pc was absolutely fine for several hours. So that was an OCed CPU at full load and the GPU at full load and power didnt seem to be an issue.

The bang this morning was from just turning the wall switch on to give the power to the PC. Its popped the last 3 times I've turned it on, and to be honest i thought it was the speakers as they do that, but this one must have pushed it over the edge. No doubt somethings blown inside the PSU.

Luckily I contacted the original place i bought it from before attempting to go through BeQuiet customer service. They were more than happy to give me an RMA number and test it out/replace.

Mine was bought back in Nov 2008, so if they replace it, it should be from a completely different batch at least.

Replacement bequiet 650 arrived. silent, even when overlocked. I guess the cap squeal of the last one was actually a fault which eventually led to it blowing up.


Side note: L4D still crashes the PC with a PSOD(pink screen of death). So the GPU is going back too.

Oh and the rest of the PC was fine. PSU protected everything.

That is good to hear SH4RKY.. It would have been devastating if your PSU took out other pieces of hardware at the same time...

sounds like a failure of the primary side - probably a faulty inductor, cap or some arcing somewhere thats taken it out. the spark was likely a cap popping or the primary fets blowing
glad the new one is better behaved and everything survived!

Its cap squeal. Some psu's do it some dont.

I had a tagan piperock (funky colors/modular) that looked ace but screamed when under load.

that said be sure its not your gfx card making the noise as the higher end cards do this aswel.

i finally know now what that noise was comming from my old gaming rig!
