Corsair HX850 850 W Full Modular 80 Plus Platinum 135 mm Fan ATX Power Supply Unit - Black

Product Information

The only downside (imo) for the RM850x (2018) would be the rifle bearing fan (its longevity) and the cables - which I don't mind that much if they keep the ripple under better control. Will the rifle bearing fan last long enough or would a PSU with and FDB fan be a better option for my ocd (hx850/1000w, ion+ 860p) So it is then up to the motherboard designer to ensure any demands through any motherboard circuit do not exceed the ATX standards. Note for graphics cards, the PCIe standard allows for a maximum of 75W through the PCIe slot. But we all know many cards demand much more than that so they get their additional power via separate power cables directly from the PSU. 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").

The 135 mm fan responsible for the cooling needs of the HX850 is the Corsair NR135P, a fan we frequently see in the company’s high-performance PSUs. Unfortunately, we cannot identify the OEM of the fan but we can tell that it is a quality model with a fluid dynamic bearing engine for longevity. It has a maximum speed of about 1500 RPM but, considering the unit’s output and efficiency, it is highly unlikely that it will be reaching this speed under normal operating conditions. The HX850 features full range fan control with a passive mode, meaning that the PSU’s thermal circuitry will not even start the fan unless airflow becomes necessary. 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. Like I've mentiond I am not interested in the digital versions even though I could set up the fan curve manually, because I find the prices a bit "too premium".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 fan Mainboard - Bo Mạch Chủ Intel Z790 ( mới ) Intel B760 ( Mới ) AMD X670 ( mới ) AMD B650 ( mới ) Intel H610m ( mới ) Intel B660 Intel Z690 Intel X AMD TRX40 HUANANZHI Intel LGA 3647

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.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.
