My computer upgrade

#1

Post by JayM » Mon Aug 05, 2019 1:16 am

I came into a bit of a windfall of unexpected extra money this month. Some of it's earmarked for getting the doggies their annual vaccinations and for the August utility bills but there was a bit left over, enough for me to be able to order a (used but tested good) AMD Phenom II X4 925 rev. C2 2.8GHz quad-core 95W CPU and a new Deepcool Gamma Archer cooler with a 120mm fan. I should get them both within 17 days, then the fun starts! I haven't swapped out a CPU in many years but I plan to do it myself now that I already have the 600W PSU installed. The total including shipping and delivery is ₱1726 or around US$33.41/€30. This will give me a slightly faster processor speed and two more cores plus 6MB of L3 cache which my current CPU (a 2.6GHz Athlon 64 x2 5000+) lacks. I've already checked and verified that my motherboard supports this CPU. I just hope it doesn't negatively impact my electricity bill, though if I understand correctly the wattage rating of CPUs isn't their power consumption per se, it's the maximum heat that can be generated before the CPU shuts itself down.

Good news: per cpuboss.com the Phenom only consumes around 6W more power on average than the Athlon, which is like a single LED light bulb so it shouldn't impact my electricity bill that much, and it runs at around the same temperature. It will probably run even cooler thanks to that huge new fan and heat sink vs. my current OEM cooler.

If you want to make up for the extra use.. turn it off ten minutes earlier or so ;)



If you are going to do what I did (double the PSU wattage capacity), yeah then you are going to make a dent.

That reminds me of my dog Sweetie. She likes to sleep next to me, and if I'm staying up too late on the computer to suit her (darn those funny British panel shows on YouTube! Quite Interesting, Would I Lie To You, 8 Out Of 10 Cats Does Countdown) she starts nagging and begging me to go to bed so she can sleep too. "Turn the computer off and go to bed, papa!"

I already more than doubled my PSU out of necessity, remember? My 250W (Edit: I looked at it more closely and it was 450W) one died on me one afternoon, or at least the 5V supply did as the fans still ran, and I had to install the 600W one that was in what's become my parts computer. (Which reminds me, it has an almost new CMOS battery in it too. I may as well swap those when I have the case open.)

In your case I doubt if it's the PSU. Just because it's rated at, say, 600W doesn't mean that it's consuming that much power all the time, it's just how much maximum power it's capable of providing. In your case I suspect it's more due to your GPU plus all those fans and things (I think I read online that the Ryzen CPUs actually consume less power than these old AM2/AM2+/AM3-socket CPUs, so unless you're overclocking it, which I don't think you are, or making a lot of snapshots, your CPU probably isn't drawing all that much power.) Although a PSU itself does consume (read: waste) some power, how much depending on its efficiency. (Mine's a cheap Xtyle brand plain-vanilla 600W PSU, not one of the new, fancy intelligent power supplies. But it was what I already had, it had low hours on it, and it seems to work.)

Same here with Doerak, my cat. He starts whining. He loves to sleep all day but there is a set time (roughly) for bedtime!

Ah yeah, indeed. And might as well!

True indeed. But regardless, I won't notice much of a difference since I pay too much monthly to begin with, which leaves me with a nice return at the end of the contract year. That return might be a wee lower, but it is still nothing really compared to all the other power using stuff in the house.

Your electric utility must charge based on an average annual consumption or something like that, which may cost more per month but it makes it easier to plan your budget, especially in the winter when the daylight is less and you consume more power. You know exactly how much your bill is going to be, winter or summer. The Visayan Electric Company where I live just charges by my actual usage every month according to the meter readings.

They read my meter once a year and then calculate what I have paid vs what I am owed.

They determine a monthly fee, calculated upon the past year. I usually up that a bit to make sure harsh winters and hot summers are covered as more power is consumed during those times.

I once had to pay hundreds extra, that is not happening to me again, that is for sure. So I pay too much to make sure I am covered in that area.

PSUs are switching power supplies so they use power roughly in proportion to demand regardless of their max rating.
The roughly is because they aren't 100% efficient and the efficiency varies somewhat with the load. Generally they're most efficient at 50% load and least efficient at very low loads. A 600w 80% efficient PSU might be only 65% efficient with a 60 watt load.

I think you've sized pretty well for efficiency.

Thanks, Tim. Considering I'm just using the onboard GPU and only have two case fans there's not a whole lot in this system consuming a lot of power right now, so there should be plenty for the "new" processor. I'm also thinking of getting an external PCI-E video card for it, as well as (perhaps) a PCI-E USB3.0/SATA III combo card. After that it will be a 20-22" 1080p-capable LED monitor, and I'll have my "new" computer! (Meanwhile my 1280x1020 17" monitor will have to do. I'll just set it aside as a spare whenever I'm able to get a new one.) I just want to be able to watch 1080p movies without having to rescale them to 720p first to prevent them from lagging or buffering in VLC. This PSU should have enough power for all of these. I never overclock the CPU either, nor do I enable turbo-boost. I usually run it with the BIOS's power-saving profile, in fact.
