Power usage issue

post #1 of 9
Thread Starter 
Hi,

My PC:

AsRock N68C-S UCC AM3
Saphire ATI HD 5450 1GB
4 GB DDR3
1TB Samsung Green SATA HDD
No DVD\CD Drive
1 USB mouse
1 USB Keyboard
AMD Sempron 145 2.8 GHZ unlocked to AMD Athlon II 4450e at 3.2 GHZ and 1.325 voltage.
PSU is a 1life 450w (I know, but has actually worked well for over 2 years now)


In November, I measured the power usage of this system and it was around 145 watts with 100% CPU load.
Now, the same build, except I removed the DVD\CD Drive, it uses 180-185 watts with 100% CPU load.

What happened? I think that for this system it seems excessive, doesn't it? Not to mention that when the I measured in November, the CPU was at 3.5 GHZ and about 1.4 or 1.375 voltage.
I connected the PSU to a 12 year? old P4 2.4 GHZ based system (it has a IDE 40GB HD, DVDRW, 1 PC133 or PC100 256MB stick, a graphics card, a network card, and the ATX motherboard). Using the OEM 300 Watt PSU, it uses around 223 watts with 100% CPU load, but, with the 1life 450 watt PSU, it uses 203 or so.

Also, my motherboard yesterday wasn't really good. I was cleaning inside the case and I disconnected the PSU to clean. Then I connected all the cables again.When I was finished, it wouldn't post (wouldn't go past the screen with the boot options and the press DEL to setup and such). I fixed it this morning by removing the DVD drive which hadn't worked in a few years and was needlessly using power. I also cleaned a lot more this morning. Maybe the motherboard isn't working very well and is using more power than it should? The CPU, RAM, Motherboard, PSU and HDD are just over 2 years old (bought December 2011).

Any help would be appreciated.

I'm not sure, but a PSU like that doesn't last more than 1-2 years, so I would replace it ASAP. It's especially dangerous to be overclocking or unlocking  CPU with a PSU like this powering your system. It's your choice to take this risk, but don't say that you haven't been warned.

I may replace it somewhat soon.
I did have a Phenom II X3 720 that at 3.6 GHZ caused the PSU to give a BSOD but then it was using almost 290 watts...
The Athlon was 3.5 GHZ for those 2 years now (although I did run it a 4.1 for while)

Yeah, I would bet that it's basically a generic 300W PSU with a total +12V capacity of no more than 350W.

Maybe... I bought the Phenom in December but I am going to sell it. But the PSU also has some wear and tear now after two years of use I guess.

What about GPU load? Was it the same when you made the measurements?

Hi,

Yes,GPU load was at idle when I measured both in November and now.
When gaming, the total power usage goes up another 10-15 watts.

It just seems weird that nothing changed but the power comsumption is around 40 watts more than it was in November. I even removed the DVD drive which should have saved a few watts.

Well, this morning I disconnected all the components from the motherboard and then put them back in one by one while monitoring power usage. Now, with the GPU overclocked at 820mhz (over 2 years like this, from 650mhz) and the CPU at overclocked at 3.2 GHZ, the PC was using 83-85 watts under 100% CPU usage (running WCG). I overclocked to 3.51 GHZ with 1.375 voltage and power consumption went up to 90-93 watts. Not really sure what happened but I like these figures. With the LCD monitor, mouse and keyboard, the whole computer is using around 115 watts which to me is good. Temps are good too (41 celsius with stock cooler and closed case). While gaming, the computer barely exceeds 100 watts (including CPU running WCG).
