QVO Series has 3 year Warranty not 5

Pros: All good. Benchmarks acceptable, not record shattering.
Cons: Only negative and reason for review is to point to misprint or whatever where Newegg says it has 5 year warranty. Samsung product page shows all in QVO series are 3 year warranties.
Overall Review: Good Product. I like the performance of mine.
Enable CSM in Bios, Not UEFI Compliant

Pros: Works after you figure how to install.
Cons: No reference to not being UEFI compliant. On board Asmedia controller needed "Third Party Sata" enabled. But this Jmicro controller did not show up till I enabled CSM. I tried to install an Asmedia controller, but it did not work. That may have been result of conflict with onboard Asmedia chip. ? ? ? Why am I installing sata controller? Because each M.2 nvme took away 2 sata.
Overall Review: On 3 year old X170 , bios had CSM upfront, but with Z590 Bios, CSM hidden on last page on very bottom line, the only line you needed to scroll to see. It was not mentioned in bios setup chapter. Next year they might completely remove it.
Old Habits Hard to Break

Pros: Great feel, many helpful hot-keys, but, see below.
Cons: Had to go back to old MS Natural Keyboard because after week of use, I could not stop reaching for hot-keys that were not there anymore. Many keys changed location but two I miss that are gone are sleep and calculator.
Overall Review: If you coming from generic keyboard to this I think you will love it.

Specs & Driver

Pros: Driver dated 2013-09-12 for ORICO PVU3-5O2U is available at ORICO site oricoonline.us Title: "Driver for ORICO PVU3-2O2I & ORICO PVU3-4P & ORICO PVU3-5O2U & ORICO PVU3-5O2I.zip". Latest Driver for PVU3-5O2U Bundled. Go to support, driver & manuals, put PVU3-5O2U in search box and look for above titled zip file with 2013-09-12 date.
Cons: There is no specific manual for PVU3-5O2U but there is a product spec page. Their driver indexing is messed up, for sure. There are several older drivers and they seem to be listed in a random order.
Overall Review: soon to purchase, regardless of other neg re-views
ANTOline is One of Newegg's Best Partners
Used to buy more often from ANTOnline before Newegg and @ma_zon started cutting the cost and offered Primier & Prime. Price, confidence in product handling, return service and overall satisfaction is still good with ANTOnline. Definitely one of Newegg' best marketplace sellers.
