The latest USB 3.2 Gen1 is also pre짯sent in the B450NH mother짯board deli짯ve짯ring extra짯or짯di짯na짯ry per짯for짯mance boosts with light짯ning fast data trans짯fer speeds rea짯ching up to 5Gbps and is back짯ward com짯pa짯ti짯ble with older devices as well as tech짯no짯lo짯gy like SATA III 6Gbps which pro짯vi짯des 2x fas짯ter band짯width than the old SATA 3G pro짯vi짯ding extre짯me짯ly fast data trans짯fer rates capa짯ble of retrie짯ving and trans짯fer짯ring HD media with incre짯di짯ble precision.

The B450NH mother짯board also car짯ri짯es HDMI 4K2K port which sup짯ports up to 4K reso짯lu짯ti짯on enab짯ling new high-defi짯ni짯ti짯on image dis짯plays with four times the reso짯lu짯ti짯on of Full HD, which express bright and high짯ly detail짯ed con짯tent that fills the enti짯re screen with life짯li짯ke images allo짯wing users to enjoy high defi짯ni짯ti짯on TV shows and movies online such as You짯Tube or Net짯flix with the HDMI output.


When it comes to Rear I/O, the B450NH con짯ta짯ins a ful짯ly packed rear I/O panel pro짯vi짯ding mul짯ti짯ple con짯nec짯ti짯vi짯ty opti짯ons like 4 x USB 3.2 (Gen1) ports, 2x USB 2.0 ports as well as 1 x PS/2 Key짯board and mou짯se port and a stan짯dard D멣ub out짯put port com짯ple짯men짯ta짯ry to its alre짯a짯dy excep짯tio짯nal HDMI 4K2K port. Addi짯tio짯nal짯ly, the B450NH also has 3 x audio ports that run on Real짯tek ALC887 archi짯tec짯tu짯re which deli짯vers 7.1 Chan짯nels, High Defi짯ni짯ti짯on Audio as well as a LAN port that comes with Real짯tek Giga짯bit LAN tech짯no짯lo짯gy capa짯ble of pro짯vi짯ding fast los짯sless net짯work connectivity.


In con짯clu짯si짯on, the B450NH mother짯board from BIOSTAR is a gre짯at opti짯on for users loo짯king for a sta짯ble base plat짯form for their new AMD Ryzen build, with ama짯zing fea짯tures and relia짯ble BIOSTAR excel짯lence, it is undoub짯ted짯ly one of the best choices in the mar짯ket for a dai짯ly dri짯ver PC used for casu짯al con짯tent con짯sump짯ti짯on, HTPC, gam짯ing or even office use. 


Key Fea짯tures:



  • DDR4 Memo짯ry deli짯vers hig짯her per짯for짯mance, hig짯her DIMM capa짯ci짯ties, impro짯ved data inte짯gri짯ty and lower power consumption.
  • Capa짯ble of sup짯port짯ing up to 64GB maxi짯mum capa짯ci짯ty and up to 4000(OC) MHz of DDR4 memo짯ry for mul짯ti-appli짯ca짯ti짯ons and bet짯ter performance.


PCIe M.2 32Gb/s

  • PCIe M.2 32Gb/s is the latest sto짯rage inter짯face, it deli짯vers the hig짯hest band짯width and lower laten짯cy. It셲 5 times fas짯ter com짯pared with SATA III 6Gb/s.



  • SATA III 6Gbps pro짯vi짯des a hig짯her band짯width to retrie짯ve and trans짯fer HD media. With this super speed data trans짯fer, SATA III allows an incre짯di짯ble data boost which is 2x fas짯ter than the SATA 3G.


USB 3.2 Gen 1

  • USB 3.2 Gen1 deli짯vers com짯pel짯ling per짯for짯mance boosts and can be used to con짯nect mul짯ti짯ple devices wit짯hout worry짯ing about com짯pa짯ti짯bi짯li짯ty. It is capa짯ble of data trans짯fer speeds up to 5Gbps and back짯ward com짯pa짯ti짯ble with all exis짯ting USB products.
