Noise and Power

Another aspect of system performance that we like to test is the noise and power requirements. Dell is marketing the XPS 410 as a multimedia computer, and in that case lowered noise levels are even more important. We tested noise and power at three settings: idle, 100% CPU, and maximum CPU + GPU. 100% CPU load is achieved by running two instances of Folding@Home (FAH). For the maximum stress test, we leave FAH running and launch the Splinter Cell: Chaos Theory benchmark at 1600x1200 4xAA/8xAF. Performing video encoding or other CPU intensive tasks while playing a game will achieve a similar CPU load.

Some of our readers have questioned in the past why we even perform such heavy stress test scenarios. After all, there are a lot of people that will never run two CPU intensive tasks along with a game to fully stress their computer, right? The problem is, we don't know what the future holds. Right now, most games and applications will not achieve the same load levels that we are using. In another year, however, newer products and games may actually reach the point where "typical use" scenarios put a similar stress on a system. We consider the maximum load test a worst-case scenario, but provided the systems can run fully stable throughout our testing then we can say with some confidence that they will be okay with future applications and games.

For the ABS system, noise results basically showed no difference between any of the clock speeds, as all of the fans run at a constant RPM. However, the water cooling fan does come with the ability to control fan speed, so we set that to minimum for idle testing and then a middle and maximum speed to show the difference in noise levels.

System Power Draw

System Noise Levels


Starting with power requirements, it should come as little surprise that faster CPUs and GPUs require more power. In comparison to the ABS Ultimate X9, the power requirements of the Dell and PC Club computers are extremely low, with the Dell using slightly more power. Using two faster graphics cards, a faster CPU, not to mention the water cooling configuration and hard drives clearly requires a lot more power than a typical midrange computer.

Looking at noise levels, all the tested computers have a relatively consistent noise output. The ABS Ultimate X9 is louder than the others at maximum fan speed and very quiet at minimum fan speed, but again we note that the X9 was not entirely stable during testing in the original configuration, and for high stress situations you will definitely want to increase the fan RPMs.

The Dell XPS 410 does very well in the noise and power benchmarks. If you had any concerns about the 375W power supply, the highest power draw we were able to achieve was 240W, which should leave you plenty of leeway. The noise levels are clearly better than the competition, and only under maximum load were we able to generate slightly more noise than at idle. Of course, if one of the optical drives spins up to maximum speed, the noise readings jump up to about 46 dB, but we're talking about constant system noise and not optical drive noise. Dell's use of a BTX form factor chassis and motherboard certainly appears to have helped them keep noise levels low; now users just need to remember to clean the dust off the fan intakes every now and then.

    Otherwise this machine is pretty solid, no question about it, ideal for making your average clueless kid an game addict.

    One thing not reasonable is the lack of RS232, LPT, PS/2 and FW, that makes it unusable as far as I'm concerned.

    Just wonder, will the ATX channel case builders ever actually LEARN how to make a proper AND cheapo case???

    It is possible and pretty easy to do at the same time, yet they are like afraid to make a killer product...

    Really...
    Most mouses nowadays are usb
    Keyboards also come in usb(although there are still a lot of PS/2 keyboards),
    RS232... USB Serial Port?(I realize the network guys use these, but they are obsolete for the general person),
    FW... I haven't run into something that "required" this for a while,
    LPT... soon there won't be many LPT printers left surviving, and again there are USB adapters.
    I wish my new motherboard didn't have RS232/LPT/PS/2, they just waste space.
    It did however come with lots of USB and 2 FW ports, which is nice.

    PS/2 usually just works, USB works, OS loads up and USB mouse turns off.I had amny times such a situation.
    That was just a single example..

    I am OK with an no-legacy approach as along as it is meaningfull.
    However to make legacy-free boards by removing all legacy stuff and not use the place for any other usage (i.e another 4-6 USB ports) is stupid.

    Also 6 USB ports as a complete I/O ? that's a joke!
    keyboard, mouse, printer, scanner, monitor, RS232 adapter and you have not a single port left!

    6 USB is nice if you have all that legacy - the big reason we use PS/2 KB and mouses is it frees up 2 USB ports.

    As for RS232, there is s huge amount of various equipment _produced_ for RS232! Why? because it makes no sense to go (pretty complicated vs. RS232) USB for simple data-reporting tasks.

    Some companies use a USB to serial chip (or emulation) to allow them to easily upgrade their products, and for something that was designed with USB in mind, which is ever increasing, it will cease to be a problem.
    I currently have 1 USB Joystick, 1 Keyboard/Mouse Transceiver, 1 RF Remote. That is only 3 ports for me, I have 4 Rear USB ports, can add 4 more, a 4 port hub (plug stuff in on my desk easier), and have 2 front USB ports. For a majority of people 6 is NO PROBLEM, there are USB hubs for a reason though.
    These computers are not designed for everyone, they are designed for most people, most people nowadays will not use the LPT/serial ports, while a lot still may still use PS/2 ports dell "provided" a USB keyboard and mouse. Most people have a mouse, keyboard, printer, and "maybe" something else such as a scanner.
    It would be great if there were 8 USB ports on the back but I am assuming the last 2 went to that card reader. Intel decided on 10 USB ports, dell would have to add in card to support more, or add an additional chip to the board.
    Monitor... did you not see the 2 DVI ports? (I don't know how you even justify listing this), RS232 is not required for most people.
    Ok I did go on a rant, but this just screams of stupidly, USB is an expandable bus; it doesn’t have a fixed number of ports, only devices which is 127(?) per controller.
    Sure they are saving quite a bit of money on an I/O chip from winbond, but in the end it doesn’t affect many people, so why not?

    Two USB on the front, six on back, two more to the flash reader I think. Keyboard+mouse takes one port (the keyboard has two extra ports on it). You've got printer, scanner, headphones, network, and maybe one or two other things that can go USB, but that still leaves one extra port for most people. An LPT/Serial card is an option if you want that (it will use a PCI slot). Most people don't need it, though. If they had put firewire in the extra rear space, that would have allowed the use of a PCI LPT/COM and still have the sound card and TV Tuner. Not sure about PhysX, though... need a PCI-E version I guess.

    "even on customs" => "even in the case of a custom setup"

    Dells Suck!


    Just kidding. When my Mom needed a new computer I had her buy a Dell. Its been trouble-free for several years.
  • Jetster - Monday, September 18, 2006 - link

    i'm really impressed with the case design,especially the internal layout, excellent airflow. easily better than the most standared atx case you can buy on the market now. and AT's statement is so true: "It's almost a shame that most people that purchase an XPS 410 are unlikely to appreciate the ease with which the system can be upgraded."
    BTW did Dell use the new video card design with the chipset on the other side? casue the hsf is facing upward, which is better imo
  • Homerboy - Monday, September 18, 2006 - link

    yeap. They are designed well, implemented even better and can't be beat bang for the buck. Sure higher-end and performance PCs will never be an pre-builts bread and butter, but they do it perfectly fine for the masses who don't know how to do it themsleves.

    And as far as their run-of-the-mill "workstations" and home PC are concerned. You simply can_not_beat a big-name manufacture on price and support.

    (*please note I build all my own PCs, but family, friends, and workplace all get pre-builts... Dell's actually).
  • JarredWalton - Monday, September 18, 2006 - link

    BTX motherboards have the slots flipped, so the case opens on the right instead of the left. That makes the GPU HSF face upward, as you can see. I didn't go into extreme detail on the BTX format, as I figure the images illustrate it well enough. :)
