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.
