Hi all, I've just picked up a BeQuiet! Dark Power Pro 11 1000w Platinum PSU. I've built my PC, it's all working fine, except I noticed one fan was always really loud. I set all fans to 500rpm in the BIOS and it was still there, checked again and it's my PSU fan. It's running at 100% speed constantly even when the PC is idle and I can't work out any way to slow it down or stop it. Does anyone know if this indicates a broken unit or whether I can change this? It's very loud and annoying for a "silent" system! Thanks

Hi guys! Basically another topic of me having weird issues with my new PC. This time it's the power supply. The PSU in question is be quiet! dark power pro p8 1000W that served me really well in my previous build (3930K one) and so I decided to move it to my new build. The issue is really simple: fan keeps spinning at a really high rpm (my guess is max rpm) making it really loud and not worthy the be quiet! name Even at idle the fans spins like crazy and I checked the air coming out of it and it was as cold as my feelings are to my new computer right now so the PSU is definitely not overheating or anything. Any suggestions are welcome

Hey guys! I just bought a be quiet! PSU, namely the Dark Power Pro 12 1200W, and my computer does this weird wind up on boot, which it did not do before. I haven't touched a thing (software) else than switched out the PSU and the cables. Further, I also noticed that it "double booted" at two occasions, which I haven't seen before, namely: - I clicked the power button - The computer booted - The computer immidiately turned off - The computer booted again, regularly into windows without any hiccup Though, this has as I said only happened two times while the rest of my "boot tests" have been normal boots with that strange fan wind-up. Here's a very short Youtube clip of the boot and the wind up: https://youtu.be/0i_swehCrbY I have also attached the same video here on the post. My question to you is if this is normal or not, and if so, what I could/should do to mitigate it? Thank you so much in advance, / Anxious PC builder video-1600453800.mp4

Hi All, Just a couple quick questions here since I'm new at custom building PCs. Recently my old PSU crapped out, the guy who built my computer originally cheaped out on the PSU and it died after just 5 months of use. It was a Thermaltake Bronze Cert. 850W even though I asked him to go with at least Gold Cert. and I didn't find out he went with a cheaper one until after I brought my pc home.. In short, he screwed up a bunch of things including installing my RAM in the wrong spots and he had left all the extra HDD sleds in and installed my SSD directly infront of my GPU so that the GPU's fan closest to the front of the pc was rubbing against the sled because it's quite long. He also didn't hook up my pump to the right header... Needless to say I have lost faith in his abilities and so I'm going to swap out the PSU myself.. I'm also wondering what would have caused the PSU to die only 5 months into having my pc? But the more important question is will this replacement 850W PSU be enough or should I go up to the 1000W/1200W model? The 1200W is actually cheaper right now than the 1000W model, not sure why? But if I do need to go up to the 1000W/1200W would there be any harm in going with the 1200W even if I only need the 1000W just because it's cheaper? Be Quiet!

Hi Guys, I'm mostly posting here to document my returns process with be quiet! as I've already hit one hurdle and I think I may be in for a bumpy ride with this one (but who doesn't love a good argument with a manufacturer?!). I should add that I've only had this PSU for just over 2 years. The manufacturer's warranty is 5 years. Currently I have a massively overkill 1000W Dark Power Pro P10 (the one Seasonic designed, according to Tom's Hardware) in my rig. As of a few months ago my PC started randomly powering off on me, but it wasn't BSODing or anything - it would just turn completely off! Then I'd be unable to turn it back on for about 20 minutes after disconnecting the mains power to it. Back then my computer could stay on for a few hours before shutting off, but as of a week or so ago it got to the point where my computer would turn off after about 20 minutes and then refuse to turn back on. How am I meant to watch an episode of The Walking Dead this way?! Anyway, I thought I best check the power supply is to blame so I pulled it from my system and sat it on my desk with a multimeter on the 5V output to check it's definitely powered up and I shorted the green wire to black and got it running. I left it on my desk for an hour and sure enough it turned off (it isn't over heating - the fan is spinning and besides, it had no load on it at the time) and then didn't turn back on when flicking the mains switch. So my fault still persists. I phoned eBuyer (an English parts retailer) on Friday (5th December) to check if I had to go through be quiet! for this warranty claim or whether I could go through them. To which they said I would need to contact be quiet! I checked the contact info for be quiet! and the only way to contact them is by a contact form or through phone (and I'm not calling Germany when I live in the UK). So I sent them a short email through their contact form on Saturday 6th December. I got no reply to that from them by today (9th December) so I emailed them in the day the following: To Whom it May Concern, I have already tried contacting yourselves on Saturday 6th December through this contact form but I may have used the wrong Subject previously as I still haven't heard back about my problem. I have owned a Dark Power Pro P10 1000W for just over two years (I still have the receipt) and it has just developed a fault where it will shut off after being turned on for anywhere between 10 minutes and an hour. I have tested the unit outside of my system by running it whilst disconnected to anything with the only load on it being a multimeter checking the +5V output as a means to check it is still on. After 1 hour the PSU turned itself off, and then didn't turn back on at all until it was left to sit for another hour or more. Am I able to get this unit replaced as it is clearly faulty. Please understand I'd like this dealt with swiftly as I am unable to complete any of my degree work at the moment as the PSU was located in my only desktop in my house. Many Thanks, DarkerMorgul Quite quickly after I received this email (it's nice to get an eventual swift response): Dear Mr. Morgul, thank you for taking time to contact the be quiet! Customer care. We regret the inconvenience have occurred to you related to a product of our company. As to your device may be a technical defect is present, it should examined by your dealer. Therefore We kindly beg you to approach your dealer to discuss the terms of the warranty. Alternatively, you can handle the guarantee by the manufacturer. In this case we beg you, to send your defective power supply with a parcel delivery company of your choice postpaid to the following address: (Shipments without freight prepaid will not be accepted.) Listan GmbH & Co.KG Biedenkamp 3a D-21509 Glinde Germany Please note your shipment must be accompanied with - A copy of your invoice - A description of the error; - And your delivery address The power supply will be tested by our technique department after the arrival. After testing it will be repaired or exchanged. The processing time is currently around 10 -12 working days. The shipping to you is free of charge for you. Have a great day! With kind regards, The Service Guy Service & IQC Department So from this I figured the easiest route would be to call eBuyer up again after I finished work in order to double check the whole warranty thing. So I spoke to a lovely lady on the phone there (I can't fault their customer service - I complain to any company whenever goods don't get to me on time and eBuyer have always been very courteous if ever I have phoned them about this, and I've used them a lot. Until they changed to using Yodel and then I vowed never to use eBuyer again). who spoke to her manager who again confirmed I should contact be quiet! directly and that there wasn't anything eBuyer themselves should be doing. Fair enough I suppose! Now when I get annoyed I can be quite snotty and my level of fastidiousness in my writing often becomes somewhat amplified. So this was my follow up email to be quiet!: Hi The Service Guy, I just got off of the phone to the supplier of my power supply and they told me I would need to handle the warranty through be quiet!. This means, one would assume, that my only option is to send my power supply to yourselves. I have checked postage cost for shipping and it would be around £70, which is about 40% of the cost of the power supply at the time of purchase. This can only lead me to assume that you will cover postage for me, how will this be arranged? As I stated in my previous email I need this power supply fixed and sorted urgently so I am able to carry on with my home study. Would you be able to ship me a temporary power supply whilst my one is being fixed? Many Thanks, DarkerMorgul Yeah they probably won't send me a spare, but if you don't ask you don't get and honestly this is my only desktop in my home with all my work on it. be quiet! need to understand that I need this fixed urgently so I can continue my studies at home with ease rather than use the dilapidated laptop that I am currently having to type this on. I can get by for the time being but I shouldn't have to! I bought their top of the line PSU because I expect top of the line performance and longevity from it. And I don't expect to be shafted with shipping costs when it's their faulty product! I don't think that's too much to ask! I will argue this until I'm blue in the face. I will not be left out of pocket by their faulty product. I'll keep this post updated for those interested! Has anyone else had to deal with be quiet! if so, was their returns process fairly pain free? Thanks for reading!

Planning a new build and the PSU in mind is the be quiet! Dark Power Pro 850W. Just wondering if that'll be enough for: i5-4670k 2x R9-290x's custom water loop (2x Swiftech MCP655 pumps and up to 11 PWM fans) moderate to high overclock I like the Dark Power Pro for: Platinum rating, sleeved cables, and acoustics (under 20dB while under 90% load). All worth the extra coin. On that note, plan on doing some coin-mining with this rig, so I'm expecting a high GPU power-draw. Will have a 1500VA UPS as well (with adaptive sinewave feature).
