Power Consumption And Temperatures

by

Power Consumption

For all testing of these value systems, power-saving features were disabled and Windows 7’s power options were set to high performance. Keeping this in mind, let’s take a look at the total system power usage measured from the AC source.

Loading all CPU and GPU cores with FurMark and Prime95 creates an almost ridiculous demand, while giving us a good look at the maximum potential load the system could face. Here, the June PC barely consumes over 250W and even stays below 300W once overclocked. The pair of Radeon HD 4850s from March do offer more performance, but at the cost of much higher consumption.

Take these CPU core temperatures with a grain of salt, as at idle, they are a fraction of a degree cooler than our ambient room temperature. While this was an untrustworthy measurement, socket sensors and finger testing also indicate we are within a safe zone. Overriding the automatic CPU and GPU fan control isn’t a necessity for stability, but keep our overclocked temperatures more in line with the stock measurements.

^ I dont like the idea of using the CM eXtreme power PSUs...
You could get a EA 430W for about $49 @newegg...
Just a thought - you could save money on the mobo by going with TOM's favorite brand ASRock board with the 770 Chipset...So with the money saved, getting a better PSU would have been a good idea...

I plan to build a similar machine so it's nice to see the numbers :-)
Again unlocking was successful the 50-50 chance do not apply to your tests.
But no surprise this is a just enough machine.

Buying the same components here, online, gets me to ~800 USD. That, including my 3% Diamond Customer discount at my favorite e-tailer. Granted, the Power Color was out of stock, which led me to Sapphire and i also had to exchange the RAM for Kingston HyperX CL7.

People in the States have way to much... fun :P

Wait, Tom's has a favorite brand? I've heard rumors in the past that Asus got all of Tom's Hardware's attention...and Gigabyte has been getting a lot of awards so maybe them...where does ASRock come into all of this favoritism, from its use in previous low-cost SBM machines?

I like this build much better than the $1000 one

This one and the $1000 show some pretty impressive efficiency and power savings over the previous, more expensive builds. Save some dough now and in the long haul. Imo thats pretty important on a tight budget build, you don't want it costing more over its lifetime than what you saved in building it.

and liked the idea of incorporating a $100 Cooler Master trio in the build.

No, this month its Coolermaster.

No shame, we all have bills.

Very well balanced system. Very helpful to see a working system with just 2 gigs ram and break the stereo type that 4 is required.

ah i miss the days when you could buy 4 gigs of ram for $20. But now that only buys you about 1gig.

You're reading that completely out of context.

if i changed the 5770 with 5870 in this build, will it be bottlenecked?

Well I dint literally mean the ASRock is THE FAVORITE brand of TOMs, but with boards from ASRock based on the X58 chipset being one of their recommended, why not have tried their AMD chipset mobo too?

Wait... Some stability issues (even at stock clocks) with this one, so the unlock was not a success. Overclocked data is for 3-cores at 3.556 GHz.

We are 2/3 if you just count SBM's. This one joins a few other unsuccessful PII and Athlon II unlocks I've encountered so 50/50 is closer to my own findings.

Our repeated advice: Spend a few bucks more on an X4 if you desire a quad.

Plus keyboard, mouse, OS...By the way I love it how Tom's makes it sound that you can unlock cores in almost every AMD CPU. I tried with 3, 2 wouldn't unlock and the 3rd didn't make it even 20 minutes through Prime95.


Plus a display too, if you need one. For us, that's $1400 alone and skews the value results a bit right?

The SBM series has never included peripherals or software. Hardware and pricing are clearly spelled out. We have complete faith our readers can add these other costs if need be.

Oh contraire regarding the unlocking. This one successfully ran many 1+ hour stents through Prime 95, but was not fully stable nor considered successful. You are completely ignoring our repeated advice of not relying on unlocking when making a processor decision.

@TA152H
I was also a fan of dual cores back then but most games and applications able to utilize a third core now.

I only find the 2gig memory quite uncomfortable since I'm using a 2gig 64bit system right now which maxes the ram occasionally so I have enabled virtual memory which sucks.
The budget could have been $600 or could use the stock heatsink to get the system to 4GB RAM.

ddragoonss :
The "Network:Integrated" and "Sound:Integrated" in the chart was really necessary?


Does it really hurt either? It's a standard component table used month after month for every SBM I've been part of. All SBM price tables included the same at one point but the other authers have since chosen to remove those rows when integrated. I still prefer they stay, but no it is not necesary. If those are the biggest complaints, I'm satified. :)
