Your pre-recorded DVD movies will look sharp on the Sony, with realistic colours - particularly with progressive scan via the component video connection. And with audio the RDR-HX1000 really impresses, creating the best surround soundstage in this group via the optical or coaxial outputs. Open Water was even more menacing here than elsewhere in this group test, making the RDR-HX1000 the best home cinema sound machine this month. CDs also sound good - better than on many midrange CD players. Had all three cables along the left side before and only the CPU cable on the middle line of plug-ins on the PSU. Put one of the three GPU plugs to the middle and its like half as loud all of a sudden.

The loud one (I say more like buzzing) is only on high FPS, but the moment I activate G-Sync on window mode too, it seems like I never get more then my monitors 144 (165) FPS. Your electric bill is only going to change depending on a lot of factors. Air conditioning and home appliances are going to take up 90% of your electric bill, and because the percentage of that bill making up your computer is so small it can almost be ignored at times. The change is so small that it is not distinguishable between your other household appliances most likely. And in that mode that loud buzzing is not there, or not noticable at all, its only that dramatic if I do Heaven or Timespy without GSync, and the FPS jump to like 300+ !Still, expensive PSUs have better build quality so the PSUs themselves are going to last longer, and if they're designed properly like this one they can be very quiet. Cheap PSUs can be loud. First of all sry for my bad english, but its not my first language, and secondly I am new to the Corsair Forum, because I would rly need some help and your opinions. After taking apart my PC several times and trying to find the noise problem, trying to put the GPU horizontal again, trying different riser cables, different PSU cables and many other things, Two EPS connectors and eight PCIe ones across four cables are plenty to cover every imaginable usage scenario. The number of SATA connectors is adequate, and the same goes for four-pin Molex connectors since we don't often see eight of them (even in the highest-capacity PSUs). Corsair bundles a FDD adapter for those folks who still need one. Power Distribution

I will still give it a shot with some cable tests, but I dont think I can get rid of that not so loud "high-pitch" whine. Its only terrible for me if I do work without headphones, you know. I just got the new RTX 3090 FE and it is doing the exact same thing, maybe even a little bit louder.

Over the last three months I built a new personal system, with the help of a friend who has done dozens of systems and knows what he does. My wife is on home office and sits 2 rooms away and its only ok for her to work if I close both doors in between !

I have no idea if that may say something to you - Jonnyguru, because to me it does say nothing, only that the second corsair PSU (RMi now) does have exactly the same problem. That explains why one would buy high-quality PSUs, sure. But it doesn't explain why one would buy such high-wattage PSUs. Buying a 1000W PSU isn't going to benefit your machine if it only needs 500W on full load. In the middle part I start Heaven, only to get some load on the GPU - like 50% workload all settings on low in heaven, nothing special, and you can clearly hear the loud and annoying "buzzing" sound. Then took it a friend's house and he had an RM1000i so I put it on his system and the RTX 3090 did not buzz. Now that 3- and 4-way SLI is on the outs, I can only assume it's just the miners that need so much wattage anymore.Scenario 1 : over the span of an hour, I do not make much noise for 59 min (15 dBA), and then for 1 min I make as much noise as an airplane (130 dBA), the average noise output will be (59x15 + 130x1)/60 = 16.9 dBA. Electrolytic: 2x Nichicon (2-5,000h @ 105°C, HD), 2x Nippon Chemi-Con (1-5,000h @ 105°C, KZE), 9x Nippon Chemi-Con (4-10,000h @ 105°C, KY), 2x Rubycon (4-10,000h @ 105°C, YXF) Nippon Chemi-Con (420V, 470uF, 2,000h @ 105°C, KMZ) & 1x Nippon Chemi-Con (420V, 560uF, 2,000h @ 105°C, KMR) An other factor is the nature of the noise : at a given dBA level, two sounds can be perceived very differently, for example a high pitch noise or a grinding noise will be a lot more annoying than the sound of the wind. the FPS goes up to like 400, 500, and more (MSi Afterburner showings) and at these setting with the high FPS and the GPU on like 50% load the sound is terrible (30 feet/2 rooms away).

Any advice which one I should go for? The Corsair ones are obviously the cheapest of those, but are they any good? I had a Corsair mouse until recently and I completely hated it, so I have kind of a grudge against that company. My interest lies especially in which one is the most quiet and which one is the most reliable.I still need a valid reason to convince me that buying an expensive powersupply is better in real life and not on paper. Does my 3090 rly want that much power from the PSU that this happens and I can do nothing about it ? And the moment I start some workload on my GPU the loud CoilWhine or Buzzing or whatever I should call it is there again. But I found out two interesting things ....... Now it gets interesting, because I put in my new RM1000i the last hour and nothing changed. I do get the exact same problems. The not so loud whine (electrical sound) in idle.
