I did this last night with the oven it seemed a waste of heat and if you close when hot the fan will switch on and take it all away
but not had to use the heating this year so far , the other thing is we never have the heating on after we go to bed
Quick rule of thumb for you: @20p /kwh 100 Watts on all day, 24 hours is nearly £0.5.
Rule of thumb 2: How much cheaper is a gas fire at heating a room than a computer? Assuming a slightly older non-glass fronted, its between 3 and 4 times cheaper than the computer is.
, on my pc my 3090 and 5800x are already undervolted for most games anyways.

So how many times a day do you use the oven in your house for cooking ? We only use it at tea time so wouldnt keep us very warm. I think you need to wake up and smell the coffee.
p.s clean ovens dont smell.
The oven here smells sometimes, bit of loose food getting toasty, only gets cleaned once a year
My point is just being in the room where heat is produced the most (oven, kettle, etc), then if possible work from that same room, and reduce costs with using no heating outside of minimum amount to keep house damp/frost free depending house/ preferences. My parents kitchen stays warm from dinner time to bed time due to warming from the oven alone which is why i mentioned it. I think if working from home and don't want expensive energy bills, getting an office duvet is probably the easiest route.
A computer is very inefficient at of heating a room compared to a radiant heater, gas heater or heat pump

People are honestly worried about 7.5p per hour of gaming?
A monitor pulls 50w or so. An average GPU pulls 200w and an average cpu 65w.
If you have stupidly specced a 16 core CPU for gaming then that is on you.
I'm using a 5600x, 3080ti and a 32 inch Samsung odyssey G7. It will cost me around 7.5p per hour of gaming.
That means if I game for 10 hours per day which I don't it's 75p per day.
I literally spend more on soda water per day to drink. It's buttons the cost to run a gaming rig.

Buy a games console.
Yep, if gaming at the lowest energy cost is your thing no pc can compete with a console or mobile device
I'll run everything at stock but not bothered about tweaking to save pennies.
Shocking though the state of bills. I've left ours on a variable rate and relying on the price increase cap as all the fixed rate deals are a lot higher and locked in for a while. Only time will tell if is was right or wrong!

People have other bills too.
At some point all those "buttons" add up.
If you saved 25p a day by make a small change it can go towards other bills or towards your soda water.
The whole point of the thread was that prices are going up.

I'm not going to change my gaming habits to save 15p per day. It's pointless.
You would literally be better off changing something else not your gaming.
For instance get rid of your tumble dryer that will make more savings than stopping gaming.
I think on the face of it, it won't seem like much of a saving. But as it's seemingly unlikely that unit rates will drop to sub 20p/kWh it'll be a long term cost to look at.
Working on a pc/laptop during the day doesn't consume huge amounts, here's a glimpse of my consumption for the office, i average a bit under 0.8kWh a day.

My PC is generally on 14 hours+ a day but only a couple of hours will be gaming, rest will be just windows/dev work. Not sure PC tweaking alone would account for much, maybe in a whole house strategy.
I agree everyones circumstances are different and there are so many different variables, electric only, electric/gas, solar power into the equation. Like I said before my current consumption is covered by the solar panels so at the moment my Electricity cost is zero WFH. Heatings not on as its not needed the house is 21c. No need for me to sit here in a chilly room like some seem to be saying in their poorly insulated homes.
Which is also another variable. Age of house (ours is nearly 30 years old). I dont think we will all be sat here shivering because we cant afford the heating and have our hands round the PC case.

I undervolt and FPS limit, not to save energy really but to reduce heat in my small mancave.
I've more GPU power than I need to run at my monitors max refresh rate so it seems sensible to limit FPS.

So far I havent had any notification of anything going up but I do have the 6900XT running up to 2600Mhz only, to keep the temps and consumption down. The RAM its running at 1.4v so not a lot, and the CPU has Curve Optimizer enabled. If I enable my 2nd monitor it doesnt allow the VRAM to go on idle and consume around 38w, so I disable it from windows when its not under use which reduces idle consumption to 18w or so.
Besides that I dont think I will change anything else, at least for now.

yea, that is the main waste. Systems powered on and idling doing not much useful.
Depends on how you look at it.
Compared to electric heater a computer is not only outputting X amount of heat watts, but also doing "useful" work for you, say encoding a video. So it is doing more for same power use
This. I have 750w PSU. Even assuming it's running at 100% and by undervolting etc. I drop that by 20%, I'm saving ~150w, or 3.6kw/day.
Assuming the tariff is ~20p/kwh, that's a potential saving of... 72p/day or £262.80/year.
That sounds like a lot, until you factor in:
- I don't game 24/7, so the majority of the time my GPU is drawing ~15-30w just rendering my desktop.*
- My PSU isn't running at 100% when gaming, so the saving would be far smaller.
- To get a reduction of 20%, I'd most likely have to hobble it so much it would barely be worth using.
* well... when idle, most of the time actually it's drawing 125w mining eth while I work
