How much electric would this use? Stock and undervolted TDP for the system?

[keef247]

TLDR I refuse to pay the amount it'll cost me a month to run a 5800x/3080/4070 etc spec new rig so I'm thinking of building a budget 1080p'ish 2nd hand rig...

What would my worst come worse wattage usage be for say a Ryzen 5 3600g OR 5600x (both 65w tdp)//3060ti system/27-32" monitor? excluding amp/speakers as mostly be using earphones anyway... ALSO what have you guys achieved when undervolted with this setup/what tdp did you achieve for your system?

Once I have this info I can just bang the numbers into a kw/h calculator with my current tarrif.

Oh and what psu will I need for this? 650w or less?

Thanks!

My secondary rig is a Core i5 10400 mini-ITX system with a RX5600XT. Still need to finish rebuilding it properly but I estimate full load power consumption to be well under 300W at the wall.The biggest power consumption part would be the GPU. My main system is a Ryzen 7 5700X and an RTX3060TI. The latter consumes at worse around 330W from the wall. I use an SF600 PSU but its quite clear a 450W PSU would be enough for my system.

If you are going for a lower power consumption gamig system,I would base it around an RX6600. The RX6600 is very efficient.





Use a CPU such as a Core i5 12400F or Ryzen 5 5600/5600X capped to their nominal TDPs,and use an mATX motherboard based around a midrange chipset(B660 or B550). Full ATX highend motherboards might not be as efficient especially with higher end chipsets. I would estimate such a system would be fine with a decent 450W PSU.

Also look at the efficiency curves of the PSU at lower loads under 50% or thereabouts.

thanks mate that's very helpful! I'm going to be using a b550m matx board

There seems to be some very good deals on the RX6600 and RX6700 on OcUK now:

I'm after building this all with secondhand parts now mate bar the psu, cex do a 3060 for £330 delivered with 2 year warranty, so bang per buck excluding a monitor this should only cost me around £700 at worst with forum price deals secondhand?

[keef247]

wow that IS cheap! and mildly tempting so I could build it as a hackintosh (amd/ati supported cards) on dual boot. HMMMM...

[cptwhite_uk]

You can get a used RX 6600 for £230 at CEX, but for £18, I'd just get new...

The RX6600 consumes significantly less power than an RTX3060 because it was optimised for laptop use. The RX6700 10GB is interesting as I suspect it might also be under 200W power draw too.

[keef247]

That's also 175w tdp vs 200w! interestingggg!!! You might have swayed me but I'll have to see what performance is actually like as I was majorly underwelmed by the 6800xt vs 3080 10/12gb.
Thank you mate!

Going by the RX6650XT review,the RX6600 is slightly slower than an RTX3060 and an RX6700 would be slightly slower than an RTX3060TI:

I have seen the RTX2060 6GB for around £200 but it is slower overall than an RX6600,has less VRAM and consumes more power.

very shagadellic! I am mighty tempted now man! I love a hackintosh too, it's why I ended up buying actual macs after building a couple of HT's...
The idea of having my cake and eating in whilst building it into my Mac Pro case (remember) would be the icing on the cake <3

[keef247]

just watched this https://www.youtube.com/watch?v=7vmGghpYbC4

you've sold me (providing them have stock in 9 days when I can buy it!) and it's brand new so hassle free <3 mint! means I can do a hackintosh now as well! nice one you legend!

[keef247]

I'm very worried now regardless it'll still eat 300w + and be pointless So I'm not sure if I should bother at all now... I'd definitely play atleast 4 hours a day if I goto the trouble of spending all this money secondhand/new parts or not!

My car yet again is tempting me to put naughty bits of carbon fibre/repaint it and do a few more handling/visuals... And she usually wins sigh lol.

I might just get myself a an older mac mini (with the same 65w tdp hardware as my current macbook pro) and that same 27" 1080p monitor and keep the existing main macbook pro as a storage machine for everything I care about/backup - then it's only powered on for that and is easily mobile and I can plug the mac mini into the tv with my logitech keyboard/touchpad combo or at the desk with the new monitor as required when I fancy a desk experience.
