The Inspiron One 2320 offers few surprises in its power efficiency. You can argue that it overachieves a little given that it draws less power than the slower Samsung Series 7 all-in-one, although only by a narrow margin. And while the Lenovo IdeaCentre B520 is much faster than this Dell, you can also see from our comparison chart that that speed comes with a dramatic increase in power costs.
One other note about this system and its power and thermal efficiency: I received a few e-mails from owners of Dell'sreporting frequent failures because of overheating. While I didn't come across any such issues during the admittedly short review process of that unit, I made a point to watch out for any similar issues on this model. I measure the temperature of the cooling vent on the back panel during a test run of 3DMark 2011, one of the more intensive benchmarks around. During that test, our handheld laser thermometer registered 107 degree peaks in temperature around the vent, with an average probably around 100 degrees or so. We've seen iMacs hit 104 degrees, so that temperature range isn't out of the question for an all-in-one.
Looking further, I ran a program called LinX on the Dell. We use LinX to test the stability of overclocked gaming desktops, and essentially it runs a series of calculations that maxes out the CPU and memory utilization. If the system can't maintain maximum performance due to heat or other issues, LinX will report an error. I left LinX running overnight on the Inspiron One 2320, and found it had successfully completed the test run when I came in the following morning. Your mileage may vary, and stability can change over time with wear, but I can at least report that our review unit passed our stability tests.
Should you need to service the Inspiron One 2320 for overheating or any reason, you'll find Dell's on-paper service and support policies compare well with those of its mainstream competition. You get 24-7 phone support, a yearlong parts-and-labor warranty, a variety of support resources online, and various diagnostic tools on the system itself. Phone support, of course, varies from support rep to support rep.
While I'd like to see faster performance from this system given its competition in the same price range, Dell has overachieved in the variety of connections going into and out of its new Inspiron One 2320 all-in-one. And even if it's not the fastest all-in-one out there for $1,200 or so, its performance is robust enough that you can still feel confident playing games or performing basic digital media editing tasks. I wouldn't recommend this system over the Lenovo IdeaCentre B520 for dedicated gamers, but this Dell is a solid buy for consumers looking for a general purpose all-in-one.
