This review is from: Rosewill CAPSTONE Series CAPSTONE-550 Continuous 550W & 50 degree C Power Supply
Pros: 80+ Gold certified
Lots of connectors
Wires to connectors are in braided sheaths
Appears to be very high quality
Other Thoughts: If do the math, you will find that an 80+ power supply (PS) will pay for itself.
For my analysis I assumed that for the life of the power supply I would operate for one full year, 8,760 hours, at 200 W ("Kill A Watt" Reading with 100 % CPU (i5-2300) and 100 % GPU (GTX 960) usage).
Now a cheap PS MIGHT BRAG about being 70 % efficient,
so power IN = 285.7 W,
thus consuming 2,503 kW•Hrs in 8,760 hours.
At 200 W, this PS will be 90.13 % efficient (interpolated using the parabola defined by tested performance values downloaded from the certifying body, PlugLoadSolutions),
so power IN = 221.9 W,
thus consuming 1,944 kW•Hrs in 8,760 hours.
Compared to the cheap power supply, this power supply will consume 559 kW•Hrs less in one year's worth of running.
I pay $0.142/k•hr, so this power supply will save me $79 in 8,760 hours of operation.
Here is the evaluation process as one big formula (efficiency is a number from 0 to 1):
$_Saved = Number_of_Hours_for_Analysis * ( Operating_Power_in_W / Old_PS_Efficiency - Operating_Power_in_W / New_PS_Efficiency ) * Cost_of_Energy_in_$_per_kWHr * 0.001
This review is from: Brother HL-2270DW Wireless Monochrome Laser Printer
Flawless Print Quality
Quiet, and in standby there is NO SOUND AT ALL
Easy setup for PC and iStuff
Great Deals on Toner!
Other Thoughts: To elaborate on the last "pro", I have found that Newegg has so many great deals on the Rosewill toner cartridges, that I now have stockpiled at over half a dozen of the 2600-sheet toner cartridges.
The best deal yielded a cost per printed page of less than ½ cent.
This review is from: Samsung 40" 2.1 Soundbar With Wireless Sub And Bluetooth, HW-E450C
Pros: Easy Bluetooth connection. (I showed someone who typically gets upset trying to do new computer things how to connect the Windows 8 laptop to the speakers, and a week later (a week without even trying to use the speakers) was able to connect happily.)
Display is nice. Shows status pretty clearly, and is genuinely helpful.
Cons: No front cover cloth for the bar. You have to look at speakers.READ FULL REVIEW
