The current BQ models are also out of the question since the only offer 5 years warranty (+ other models perform and/or are designed better) Each of Corsair’s seven PSU series has been developed with a specific market group in mind. The company is constantly upgrading/adapting the products of each series with new revisions, but the specific market group for that series always remains unchanged. For example, their first series, the HX, was developed to target the demanding high-end market. The original HX520W and the HX620W are now but a distant memory, yet the HX series is still targeted towards demanding PC enthusiasts, consisting of eight high output (750-1200 Watt) units with very impressive specifications.
Now my (several) question(s) would be: in this specific case, where I'm going for a more "silent airflow build" and with the components mentioned above, would the 3 PSUs be sufficient and quiet enough?Finally, the APFC converter is well-designed. Its readings are sky-high, even during the 10% load test. I'm not particulary interested in the digital HXi line, I'm more an analog dude (set it up and forget it). So in multi-rail supplies, there will always be restrictions preventing delivery of the full capability of the supply. When it comes to efficiency, the HX850 has no problem with 80 PLUS' Platinum requirements at 20% and 50% of its max-rated-capacity load. Under full load, it comes very close. Under normal operating temperatures (80 PLUS only tests at 23°C +/-5°C), we are pretty sure that the HX850 would easily pass the full load efficiency requirement as well.
I'm well aware that expensive psu =/= better or higher quality psu. It all depends on the design quality of the original platform and how well it was executed/modified (+other factors) in the end. There are more sophisticated multi-rail supplies that can automatically redistribute some of the available power from one rail to another rail. But they must always leave some in reserve on all rails. And note those supplies are also more expensive and more complex with more components that might fail. If not, would the HX1000 be a more "safer option" and does the price tag justify its quality? (not the current price tag but overall, since the market is f-ed anyways) regarding the recommendation of the EVG G3 kill-a-watt - EVGA in general isn't known for silent PSU models or am I wrong? If you're going for the least powerful unit that will suffice for your needs, you're probably going to be running it at higher than 50-60% loads frequently. And you'll be losing a bit of efficiency then too. Factoring in that sweet spot for efficiency generally means a significantly more powerful PSU than one might theoretically be able to get away with(like basically 2x as much power as you "need").PSU - Nguồn Máy Tính Nguồn Cooler Master Nguồn Corsair Nguồn Silverstone Nguồn NZXT Nguồn MSI Nguồn ASUS There is a switch that lets you choose between one +12V rail or multiple +12V rails. Across the HXi family, this is achieved using Corsair Link software. However, since the HX models don't have a digital interface, a different approach had to be used. As for the AX titanium line which is a modified SS prime platform - I never suggested that it's better even though it is considered and offered at a premium price.
CPU - Bộ Vi Xử Lý CPU AMD CPU Intel CPU Intel 14th ( mới ) CPU Intel 13th ( mới ) CPU Intel 12th CPU Intel Xeon CPU AMD 7000 Series I know all the differences between these models as well as the tech specs and components used (cables, fans) so there is no need to go into all of those details (thanks to JG forum, Tom's hw/Aris and couple of other reviewers and guys here on LTT forum). The thing is I would like to buy first and foremost high-quality (reliable/proven platform) psu which is silent and would basically work as an almost passive "solution" at 500-600w, or with a loosely profiled fan spinning at low rpms at that wattage. Avoid the coild whine would also be preferred. By sufficient I also mean - would the 850w models be enough to not have any problems with current and future GPUs (transient loads which would trip them in some cases and shut them down).
The Corsair HX850: Introduction
On the other "downside" the FD Ion+ OEM is High Power which isn't exactly known for high-end PSUs even if does look better than any other model they've made so far. What turns me off from the RMx is the potential coil whine (which plagues almost all Corsairs models lately) and the rifle bearing fan (getting louder after couple of year). The HXi platform (imo) is a bit old and probably needs a slight "refresh", at least when in comes to the cables and the volt. regulations at +12v. ( Yes I know that Mr. Gerow said that its furthest down the line to get a "facelift" and I know I'm not competent enough to judge it)
Which one of these 2 would be the better overall option when it comes to build quality (reliability) & silence, while also avoiding the coil whine "lottery"? FD ion+ is one example, it did look like an overall good option but with 3,5/5 rating it gave an impression it was mediocre (until you go a bit more in-depth). I would say it is better than say the new BQ platinum line. Technically maybe not on-par with the RMX850, but pretty close and with better cables and a good FDB fanAre there any other models from other OEMs/brands in this price range <200 euros (even if the market is kind f-ed now) which are comparable quality-wise and also when it comes to silence?
Great Deal
