Hey guys,

I am looking at buying a new pc that will be left on to run 24/7 that will always be at about 70% cpu usage per day.

I am currently looking at E5-1650 v3 3.50Ghz 32GB RAM 240GB SSD Quadro M6000 which I can buy for cheap, it is in near perfect condition as it has been sitting in the corner of our office and I know it has never been used.

Will this chew alot more power and increase my electricity bill as this cpu was made in 2014. Or can I undervolt the cpu to keep it in line with more modern cpus.

Any knowledge you hardware guys can provide would be greatly appreciated.

TDP 140 W

70% constant use

Yes it will use power.

Is it worth buying a newer pc to save on my electricity bill?

I can get the 140 TDP for about 1/4 total cost of getting a new pc.

Just trying to workout if electricity will cost me more than the amount I will save on buying newer parts.

-To be fair, we cannot answer this question.

Probably, you would need to calculate the costs based on consumption, cost of electricity in your area (which may vary over time), as well as the length of time that you intend to run the machine. If you intend on having separate cooling systems in place, then you will also need to calculate those costs. If the machine is no longer under warranty, then you may also need to account for possible maintenance and parts replacement etc..

But you asked about undervolting. Even then, this is probably something that you would have to check for yourself. Run the system normally, gather all of the necessary data, then run the system while undervolting to check the difference and compare your potential costs.

Similar to what ++METHOS said, there's a lot of 'variables' that will also play into any kind of cost you will face that makes it kind of hard for anyone to give you a rock solid answer.

Some examples of things you will need to consider / factor into your choices:

1. Cost of Electricity

This is going to be a big factor in terms of overall price / expense. The cost of power wildly ranges depending on where in the world you live. In some areas, power is so cheap that you don't need to care/worry about it pretty much at all. While in other areas, it's so expensive it is a prime factor you have to budget for year round. There are also areas where the cost will vary based on the time of year which may also factor into how you need to budget certain things.

2. Quality of Parts
3. Overall Part Selection

These two points go hand-in-hand. There is more to a computer than just the CPU in regards to what pulls power. And the quality of those parts can also play a huge factor in what is 'eating' power. You can have two entirely different motherboards that will land up drawing vastly different amounts of power based on the quality of parts used on the boards.

This lends itself into another point to keep in mind, heat. The most power your system will land up drawing/using, the more heat it will produce. That heat will need to be dealt with in some manner and depending on where you live, that could be another issue. In some areas, the heat may be a welcomed addition and can help lower the cost of heating by other means, but in other areas, it can be an added expense as you need to rid the heat as much as possible to avoid overheating or other issues.

4. Best Part For The Job

This is something we can't really make any kind of input on since you didn't explain what the system will be doing. There are many many advances in various aspects of a CPU that have happened over the last 10 years on both sides of the coin. (AMD vs. Intel) So it is hard to say if the CPU you are asking about is the 'best' part for the job you want to accomplish.

There is a chance that the workflow you are using would be better suited on an AMD chip vs. Intel where in the last several years, AMD has absolutely destroyed Intel when it comes to multi-core tasks. Or if the task is single-threaded, Intel has continued to dominate in that regard.

Along with this, there are various different chips from each of these companies that could potentially better suit your specific workflow that are both old and new. Not all chips are created equal or have the 'best' handling of various things across generations. While a chip from Intel from 10 years ago may be an absolute beast at handling 'x', their newest chip may not. The same goes with AMD.

For example, with AMD, their newest lineups can be absolute beasts with multi-core workloads. However, in gaming, you can actually get a performance lost if all cores are enabled. It is better, in some situations, to 'park' or disable part of the CPUs to get better performance depending on the workload.

5. Efficient Software Usage

This is another hard one to go into much detail about since you didn't say what the workload is that you are doing. But, something to keep in mind and look into is seeing and knowing if whatever it is you are doing/running is the best fit for that job/task.

It is possible that there are much better software solutions available to complete the task you plan to run and can do so in a much more efficient manner. For example, if the current solution you run will always take up ~70% CPU usage, there could be a much better optimized solution that can do that same work at only 30%. Or, there could be another solution that can also do the work at 70%, but at a much more efficient/faster rate.

6. Configurations

There are a ton of different configurations that can be made on a computer to greatly improve (reduce) its total power draw.

Some things that you can look into configuring/tweaking would be:

- Disabling any extra features on the motherboard you do not need/use.
- Disabling any extra ports on the motherboard you do not need/use.
- Disabling extra CPU features that are not needed.
- Disabling parts of the CPU. (ie. AMD allows you to disable one (or more) CCDs)
- etc.

Next, another big factor that can help reduce the stress on the CPU is how your setup will make use of RAM. On most modern setups / CPUs, the memory controller is build into the CPU now to get the best performance. However, this means that there is now the added 'cost' to running higher end memory in regards to power and heat.

If your given task does not require it, it can be heavily beneficial to configure the system to make the RAM is unimportant as possible.

- Run the system in single-channel mode with only one stick of RAM.
- Ensuring the RAM is running in a proper timing configuration.
- Underclock the RAM to make its speed as low as possible to reduce any kind of extra stress on the controller.

Then, other configurations that could factor into this would be that of the software you use. Making sure it is configured to best serve the task you are trying to complete. Without any info on what you are even doing, that will be ultimately up to you to figure out.

---

There a ton of other little tid bits that could be looked at in regards to what would be best to look into as well, however this is some surface-level things to keep in mind. Without more information as well, it is hard for us to really do much in regards to any kind of recommendations for you other than generalized suggestions.
