System Builder Marathon: $625 Gaming PC

Power Consumption

A number of readers have repeatedly requested that we add power-consumption data to the SBMs, and this month we are now able to provide total system power (of just the machine itself) measured from the wall outlet. 

Low-level overclocking with Riva Tuners was quick and easy, but it dramatically raised our idle-power consumption as the high clock speeds were running both in 2D and 3D. When overclocking with CCC, the 2D clocks cycle down to a very low level, so the extra 40 MHz gain that Riva offered compared to CCC did provide some extra FPS in games, but it came at the expense of full-time lower energy efficiency.   

Under load, we see the added power demands that our increased voltages and clock speeds have on system power consumption. 

For SBM performance testing, power-saving features such as CPU Enhanced Halt and CPU EIST Function were both disabled. Also, Gigabyte’s Dynamic Energy Saver Advanced was not installed until all testing was complete, as we did not want any interference when reaching our maximum overclocked speeds. After installing and enabling these utilities, power consumption in idle mode dropped to 89 W while load consumption dropped to a more-impressive 180 W. However, no performance testing was conducted with these settings and we can’t assume there was no loss in performance when enabled.

    Sure they could give a 625 dollar AMD setup, but it just wouldnt be as good at this time so why bother?
    Its always about value at the price points.

    What’s the point in an AMD setup when the Intel option gives you better value for money?

    lol... my e5200 crapped out at 3.7ghz 1.4vcore... someone i know got his e7300 to 4.0ghz at some ridiculous vcore though lol... it really depends on teh chip. some get good VID's, some get bad. some overclock good, some overclock crap, its the natura of binning. naturally e8400's would be binned more than the 5 and 7 series, and the e8500/8600 would be better still.

  • when r u guys gonna write about the nvidia ion platform?!?!?!?!

    i wouldn't risk buying an e7300 over an e5200. i have built amd systems, now i'm regretting why i didn't bought pentium dual core which are practically core2duo's with less cache.

    regarding nvidia ion, i think intel is thinking deeply of whether they allow nvidia to Atom since netbooks still sell without it.

    I actually just got done purchasing parts for a new pc that ended up being around that same price. This is my first time building a PC so I'm not sure if I could have done better, but I think it's worth mentioning if anyone is interested in going for a Quad Core instead of the Dual Core.

    Intel Quad Core Q6600
    Asus P5QL Pro Motherboard
    NVidia 9800 GTX
    GSkill 4 Gb Ram
    580 Watt PSU
    Rosewill Mid-Tower
    160 GB 7200 RPM Hard Drive
    SATA CD/DVD Burner

    I guess I will share my for-Christmas build with TH.

    $82 2.5GHz E5200 45nm C2D
    $0 (no CPU cooler)
    $54 ASUS P5KPL-CM
    $34 A-DATA 2x2GB (4GB) DDR2 800
    $200 GeForce 260
    $55 WD 320GB WD3200AAKS
    $0 integrated sound
    $0 integrated network
    $12 Spray painted an old beige case black.
    $67 500W SeaSonic
    $22 LG DVD burner
    $10 card reader

    $526 Total

    I don't see why they didn't shave off $40 for the cheaper CPU

    That is a nicely configured system at fair pricing
