Power Consumption And Temperatures

Power Consumption

Last quarter's PC was driven by an Antec EarthWatts 430 W power supply with an 80 PLUS Bronze certification, while today's employs a Rosewill Green Series 630 W model with the more vanilla 80 PLUS cert.

Processor power saving features are enabled on both rigs. Meanwhile, the CPU and graphics card fans are controlled automatically, yielding quieter operation.

To see both machines consume only 56 W at idle, and so little under load, is simply amazing. Props to Intel for its efficient Sandy Bridge architecture, and to AMD for the low 2D idle consumption of these 6000-series Radeons.

While the performance of Intel’s bundled cooler isn't particularly impressive, it facilitates quiet operation and adequate cooling at stock frequencies. XFX's graphics cooler exhausts very little air out its rear vent. However, thermals were hardly a concern inside our small microATX mini tower. 

Automatic fan settings on the XFX Radeon HD 6950 never accelerated beyond 39% of the available ramp, even when the GPU was mildly overclocked. So, there's cooling to spare in the event we want to venture above Overdrive's frequency ceilings. Likewise, the more aggressively overclocked Radeon HD 6870 used last quarter only spun up from 37% to 40% to cope with the added heat from overclocking. Neither machine is silent, but both are adequately quiet.

    so now that all the 6950's are deactivated or $289+, is this build invalid? because a 7850 is looking really good right now...

    I appreciate what they're doing, but at some points, I can't help but feel like a cheap bitch.

    Making decisions overly measly amounts of money ($10) is just dumb. Work an extra day and just get the hardware you want. Or, don't go to the movies or out to eat for a few weeks.

    To me, there's a certain area, at which being cheap, just rips you off - you'd be better off spending a little more, and getting a much better item.

    Let me get this straight... you raised the budget $150 "as a result of steep price hikes on mechanical storage", then only spent $85 on a HDD. You really just wanted a more expensive graphics card. You could have taken the $70 processor savings and the $65 under-budget HDD savings and nearly have had a $500 build.

    very good read.
    nice to see where core i3's limits lie.
    i wonder if you guys will consider amd's new fx 6200 or fx 8120 for the $1200 build, with 78xx series in cfx.

    if I had $600 for a PC, I would go with i3-21xx, 6870, a better mobo and a better case.
    it is probably the best thing to do

To me, there's a certain area, at which being cheap, just rips you off - you'd be better off spending a little more, and getting a much better item.It's not an issues of whether they had the money or not, it's a matter of principle, you set your budget and goals at a certain point and then you make choices. Sure, not everyone will be happy with what they chose but that's what forums are for.

    Anyways, anything a bit over 60fps (on a 60hz monitor) really isn't that bad, i mean you might lack the bragging rights but at the end of the day, it's about gaming and feeling satisfied that you shot enough monsters. To further empathize that having 70 fps constant is not total shit because another GPU can serve you 130 (as if you're going to notice without watching the fps counter) my one suggestion for this SBM would be to introduce a different style of graphs. Below 30fps all the colors of the bars to be grey and over 60 the same thing. This to focus the attention on most relevant (to my opinion) segment. I've seen a lot of ppl chase those fps numbers, buying expensive GPUs only to have them sit in a bad enclosure, sub par motherboard or weak CPU.
    Even in gaming, i believe balance is key.

    Great Job! These builds keep me at Tomshardware!

    Only thing 1 thing, you said an I3 was used instead of an I5 on this page...

    You can check the 600 dec build here...

    Pretty sure an I5-2400 was used.

    I'm glad they used a i3 2120 for the CPU, but I wish they would have used some of the newer cards like the HD 7950 or the GTX 560 Ti 448. these are roughly the same price. Spending and extra $20 on a PSU was a waste. the EA430D and 380W are the core of the budget build. I would like to see some testing of a few of the less expensive PSU ($50 or less) to see which are junk and which aren't bad.
