Hi, I want to do a bit of ether mining on the side, but not sure if my pc can handle the cards.

My power supply is gold certified 700w.

i currently have an rtx 2060 but i was wondering if i could also add like Ti card in there. or a low power usage one to boost my MHs

Any ideas?

Update: I got my hands on an RTX 3060. Im now Running an RTX 2060 and RTX 3060 both mining overclocked on my 700w PSU. There are no issues, I have spoken to some miners I know and they also said it's fine too, core clocks are fully underclocked so very little power is being used, if I'm gaming I tend to turn off both gpus to ensure I have enough power.

Currently getting 75MH.

Not with the immediate intent to purchase a new PSU.

Use the link and the listed calculators to determine the power requirements of your system. If any component has a power range then use the high end wattage value.

Pay close attention to the recommended PSU wattage listed in GPU specifications.

Also do you own manual wattage total and add 25%.

As I understand the rtx 2060 specs recommended PSU is 500 watts. Likely that, overall, your 700 watt PSU will be insufficient if you add another GPU.

= = = =

That said, my thought is that you should reconsider your mining plans.

Mining is very demanding on a system. And with all the current problems regarding the availability of GPU's you may not wish to put your rtx 2060 (or any other GPU for that matter) at risk. Along with the host computer in general.

Especially when it is very unlikely that the mining will be profitable.

Successful mining is not an "on the side" proposition. Mining is 24/7 with multiple banks of multiple mining rigs.

Your unit is very low on this psu suitability list:
I do not see a gold rated psu named as such.
Can you provide a link to the specs of your unit?
Failing that can you post a photo of the data plate on the side of the psu?
 
Ridiculous? Did you post this question just to be told what you wanted to hear? You don't need a new PSU. Your existing one is more than capable of running a 2060 AND whatever else you want to put in there. You could put a 3090 in there and it would still be perfectly fine.
By all means, please do that @TommyTwoTone66 . Please put a 2060 and a 3090 and try to power it with that PSU and tell us what happens.

You are starting to give dangerous advices man. You should educate yourself a bit more about PSUs and their quality's importance in the system.

You need to list all the system parts and the brand, model and age of the power supply.

I don't plan on selling the etherium right away, I actually want the coin because I believe it has potential so it doesn't need to be super profitable. More just breaking even. But ok is there no low power consumption cards that might cope on the 700w?
 
Good points from Ralston18. ^^^

What is the make/model of your psu?
Gold rating and 700w means little.
In fact 700w is a clue; modern quality units seem to come in 650/750/850
Quality means all.
A poor psu will not deliver advertised power and will do even less in the confines of a case where heat builds up.

What is your processor? Is it overclocked where it draws extra power?
Here is a handy chart as to what is recommended for different graphics cards:

Considering the current high cost of good graphics cards, your plan may not yield what you hope for.
What cards are you looking at?

Dissent and discussion is one thing, you've taken it upon yourself to troll this thread and the OP with dangerous advice. Its been well established that the OP's PSU is poor quality and not even worthy of the power it is "rated" at.

This is your only warning this type of dangerous advice and behavior is unacceptable here. You will no longer be replying to this thread.

Yes still fine. Please do it and post back your hash rate because these other chumps seem to think that a 700W PSU isn't up for the job, based on... nothing?
You don't know what you're talking about and what a <MOD EDIT: Profanity> groupregulated unit is doing with the voltages in a system that 95% of it's needed power want from 12v.

Generally speaking, 700W is fine for mining with two mid-tier cards, provided the rest of your system isn't pulling much power. Etherium mining doesn't use much power when your cards are properly optimized for it. For example, I'm running two high-end cards (RTX 3080 and RTX 2080 Ti) off an 850W PSU right now. The whole system only pulls 480W at the wall, so there's plenty of headroom.

Also, I'm quite surprised by the heavy-handed moderation in this thread. It's true your PSU isn't of great quality, but TommyTwoTone66's assertion that 700W is sufficient power for mining with two cards is absolutely correct. I'd even go a step further and say it's common knowledge in the mining community, given that your cards should be configured with a reduced power limit. It's worth getting a quality PSU if you plan on mining 24/7, but 700W is a sufficient power budget.

Not that I need to explain myself here but you do make a point that is important to note.

Nobody whom had posted in this thread is disputing that 700w is plenty of power to do what the OP wants to do. More than enough even.

The issue comes into place with the following, the quality of the PSU that the OP has is VERY low, and especially with GPU prices right now, do you want to be running two expensive pieces of hardware 24x7 mining (ie when you aren't sitting in front of the computer where if/when something goes wrong you are there to stop it)? In addition the person ignoring this fact was personally attacking those who disputed him, and the OP, as well as adding fanatical theoreticals. All of which goes against the rules and spirit of this site. We want people to get good, safe, knowledgable help without abuse.

And so he is no longer posting in this thread. This is the end of discussion on this, if you have any questions on my decision feel free to privately message me.

Of course, the classic downvote + everyone's a chump except for me comeback reply for when you really need to defend the idea that MoAR wAtTs = beTteR QuaLiTy!!!! no matter what's going on in the thread.


EVEN when Aerocool units have a bad rep when it comes to quality.

Under that idea we could even say that a crumbling coal power plant with rusty generators from 1890 that produces 5MW is better than a last gen combined cycle that only produces 4.8 solely because the first "has more watts".

When it comes to quality a CX650 (that's an entry level PSU) would absolutely beat the Aerocool.

edit: downvoting me with alts and backing your own comment won't make you right so I'll proceed to LOL

@Jay_16,

This: "Im now running a 3060 and a 2060 on my 700w power supply both overclocked getting 75MH. no issues at all. "

That can certainly be so.

However, in my mind the matter is not that the GPU's will or will not run/perform/mine with any given PSU wattage or rating/efficiency.

Especially when those values were likely "established" under ideal conditions and possibly statistically skewed one way or another....

The question is for how long will it run? Especially with overclocking and numerous other system demands for power.

Mining needs power. Power generates heat. Heat destroys electronics.

Hence the need for more cooling which in turn needs even more power.

And details do matter....

@Rogue Leader summed it up nicely in his post (#26).

For me the mining risks to the GPU(s) or overall system far exceed the little chance of profit to be made.

Especially with your competition being entities with vast mining rigs. (Google "bit-mining rigs images".)

If someone wishes to mine then the important thing is that they understand risks involved: short-term and long term.

Right now, the GPU market being as it is, I would not want to have to go looking for a new GPU.

Keep a very close eye on your system.

Just from personal experience over say the past ten years I always leave my PC on, sometimes with games on pause for days with the gpu running high. Its stupid as it wastes electricity but the only components I've had fail are 1 hdd and 1 ssd. Hell at my old work place we had off the shelf Dell pcs running 24/7 for at least the 7 years I was there and only 1 was replaced in my time, 1 was in an enclosed metal compartment at about 100 degrees from 2000 and it was somehow still going strong in 2018. Mining ethereum isnt taxing on the system really apart from the gpus vram especially if you undervolt and underclock which is almost a must for mining. Could mining break your gpu or psu? Sure it could but they could also fail during a game of fortnight which is probably more taxing on the components.

If you already own decent hardware thats fine but going out and buying 1 gpu to add to your system for mining on the premise Ethereum will skyrocket is stupid though, it would probably be smarter to just use that money to buy some ethereum.

Heat does kill component I understand that. The side panel is removed and the fans are sitting around 65-75% which is perfectly fine.

the Vram temp hits a max of 81c and the overall temp of both gpus sits around 65c. So I really don’t see much risk to the gpus at this temp, especially when it runs a lot higher when gaming.

I realise people think that it may not be profitable, and maybe not.

but at the minute I’m pulling a nice little bit of extra cash a day and I would like to emphasise that it’s more of a hobby than a business.
those gpus are mining me the crypto I want and I believe in it’s long term potential.

Just as a general observation I will say no - there are no low power consumption cards that will work.

Mining (any crypto) needs power whether you intend to make a profit or not.

https://zipmex.com/au/learn/bitcoin-mining-hardware/

Again you are taking a risk (but that is up to you) of damaging your system in some manner for comparatively very little gain.

Breaking even is one thing. Breaking your system is another....

There may be other ideas and thoughts on the matter. Risk is subjective.
