High efficiency (really!) and a true sine-wave UPS

CyberPower CP850PFCLCD PFC Sinewave UPS 850 VA 510 Watts PFC Compatible Mini-Tower
CyberPower CP850PFCLCD PFC Sinewave UPS 850 VA 510 Watts PFC Compatible Mini-Tower

Pros: I used to design UPS systems, and I wanted to get a good unit to modify as a CPAP inverter and include a larger external battery. I have been using a larger version of this unit (1500VA / 900W) and have been very happy with it. This one has been very reliable and very low power losses. And yes - it is a proper sine wave output. Like most in this price range, it is line interactive. That means that the end load is usually just attached to the utility with a transformer being used to improve the line voltage range. The inverter is a 12V inverter that feeds a winding on the same transformer. There is a single 12V 9AH gel-cell type battery. This unit came from Newegg with much better packing than Newegg has done in the past. The Cyberpower retail box was inside a larger box with bubble wrap. Much of the bubble wrap had been popped from shipping, but the UPS arrived in good shape. I was very glad to see the extra packing. I have received several UPS systems from Newegg in the past with the UPS systems damaged. I used the software from their website to turn off the sounder, which worked great. Note: when pushing the button to power on or off the UPS, the sounder still will beep to warn you that you are killing the output or flaming it on. I personally like that to keep from making a bad mistake.

Cons: No problems, but the battery is quite small and will not last long if you drop a heavy load on it often. In general, the higher the load the shorter the battery capacity and overall cycle life will be. This is also true of more frequent power outages, even short ones. This is common to all UPS systems.

Overall Review: Efficiency numbers: Unit plugged in and off (no output, charging battery) = 4W at battery float Unit plugged in and on (no loading, charging battery) = 5W at battery float Peak input power in at no load on the output and maximum battery charging = about 23W Unit on battery (no load but maintaining the output voltage) = 1.8ADC (about 22W inverter losses) Never us a UPS above 80% of its rated watts, which for this one which is rated at 500W, that would be limited to 400W. Higher than that will be risky (all UPS systems are this way). The internal temperatures will be very high, and battery capacity and shelf life will suffer. I plan to keep this one below 200W. The VA rating is mostly useless these days, with clean PFC loads. The inverter higher VA does help with inrush on motor loads, though. Note that the internal charger cannot charge a very large battery, maybe up to 20-30AH added externally. I connected a 100AH externally with a charger and line triggered relay. In an extended outage, I can run my CPAP and a floor fan for nearly 12-14 hours (almost two nights). When adding an external battery, plan your fusing or breaker protection carefully. I have been very pleased with Cyberpower products. They use nice designs and are manufactured well. I am all set for another squirrel getting into a transformer (**flicker** ... **boom**).

DId not work on old Intel motherboards for TDS5000 scopes

3.5" SATA HDD to IDE/PATA Adapter Card ,SATA 22-Pin Hard Disk / DVD Burner to IDE 40Pin Interface Motherboard Converter w/ Molex 4-Pin Power Header

Pros: I have bought several devices from EN Labs before, and this is my first failure. This SATA drive to IDE motherboard adapter would have been a perfect solution for what I needed. It plug onto the SATA drive directly, so there has to be room around the HDD/SSD for the board overhang.

Cons: I bought one of these to try adding SATA type SSDs to some old 2004 scopes that only had IDE. This did not work on any of these TDS5000 series scopes. The motherboards have the old i845 and i865 chipsets. I have used several other SATA to IDE bridges before without issue, and the board had proper power connected. I did try a SATA DVD drive with it, and that drive worked. But I bought it to work with SSDs and was planning to buy many of them if it worked, but it did not.

Overall Review: This could be due to a timing error or other signaling issue, but I wanted to alert that this does not work for all motherboards.

Very happy with this NVME SSD!

SAMSUNG 980 PRO SSD with Heatsink 1TB, PCIe 4.0 M.2 2280, Speeds Up-to 7,000MB/s, Best for High End Computing, Workstations and Compatible with Playstation5 (MZ-V8P1T0CW)

Pros: I installed this in a 2015 era i7 system that was using a SATA type SSD. It was a bear to get Windows 10 converted over, but once it was running correctly, the 980 Pro rang great. In this older system, the transfers were about 1.7GB.sec to another NVME on a PCIe card.

Overall Review: I did not find any free software to convert the old MBR formatted SATA SSD to GPT for the NVME SSD, so I bought a copy of EaseUS Partion Manager to do it. The "clone system" worked well, after learning that a simple "clone" does not work. The new NVME SSD has to be seen in the Windows environment first before cloning can be done. Hope this is helpful to others.

Was tough for me to get the MBR partition moved over to this, heaksink does not touch all chips!

Western Digital WD BLACK SN850 NVMe M.2 2280 500GB PCI-Express 4.0 x4 3D NAND Internal Solid State Drive (SSD) WDS500G1XHE w/ Heatsink

Pros: Once I got this going, it was fast (>1.5MB/sec). Used this to convert an old 2015 era PC to NVME. The old drive was an MBR partitioned SATA and this NVME SSD was partitioned as GPT which I read is necessary to boot from NVME. It was a bear to get done, but I am happy now that it is working.

Cons: The heatsink does not come into contact with all of the SSD chips. So those chips rely on the thermal resistance through the PCB and the other chips to get reasonable cooling. I ended up putting a system fan blowing on the SSD to get the temp numbers down. The WD utility does not give good direction for converting / optimizing / configuring. It did not have the ease of use as the Samsung utilities that I have used before. I hope they polish this a bit more, and add help for users on setting things up.

Overall Review: I ended up using EaseUS Partition Manager to convert my old MBR formatted SATA to the GPT formatted NVME. Use the "system clone" function and not the "clone" function. Make sure windows is able to see the NVME with the Windows system drivers working (if using this in Windows).

Worked great, creative design

StarTech.com PEX4M2E1 M.2 Adapter - x4 PCIe 3.0 NVMe - Low Profile and Full Profile - SSD PCIE M.2 Adapter - M2 SSD - PCI Express SSD

Pros: Used this to add NVME to a 2015 era PC. The design looks simple but is actually quite complex, with curved traces to help from wave reflection / standing waves. The only active circuits appear to be a power supply. No driver needed. This also includes a half height back plate adapter if you need that.

Cons: I would have liked a spare NVME screw. These are very small and I expect hard to find.

Overall Review: This worked great with no issues. I ended up using EaseUS Partition Manager to convert my old MBR formatted SATA to the GPT formatted NVME. Use the "system clone" function and not the "clone" function. Make sure windows is able to see the NVME with the Windows system drivers working (if using this in Windows). Even on a 2015 machine, I was able to get 1.7GB/sec transfers to another NVME.

They take a while to get here, but very good quality if you are willing to wait

Dual 2 Ports USB 3.0 Back Panel to 20pin Header Cable with PCI Bracket
Dual 2 Ports USB 3.0 Back Panel to 20pin Header Cable with PCI Bracket

Pros: I bought 4 of these and the ones I have installed have worked great with good speed when I tested with known good USB 3.0 flash drives. I also used these to add USB 3.0 capability to the Sedna Dual PeSATA 3.5" front panel card. You have to trim the blue plastic away from the USB output side connectors to make it fit right and look clean to the outside world. For reference the Sedna front panel card is: https://www.newegg.com/p/1B4-0001-00002?Item=9SIA1JM0FD6650

Overall Review: Very happy with these cables. I did not mind the wait since it helps keep the mailing costs down.

Item arrive well packaged and in good condition

Sedna offers good alternatives for add on cards, as well as hard to find solutions. What I ordered is a unique front bay 5.25" dual PeSATA port (powered 12V/5V eSATA with USB 2.0) and Molex power out. I desoldered the Molex power output connectors and glued down two USB 3.0 port using epoxy. Now I have a dual PeSATA port and dual USB 3.0 front bay card.

Relatively fast delivery, good communication, good product

The seller contacted me very quickly after my purchase to say that they were out of the color cable that I ordered and offered a different color or a refund. I chose the different color, and received them a week later. The cables were very well made and functioned with the dual connector type (Lighting and USB micro). Very happy with these cables.
