Topic: 930~960w on 1000w psu. safe or not? - page 2. (Read 1665 times)
It’s definitely not safe. Above % 70-80 is not safe. Even in that margin its calculated regarding psu decreasing everyday. You should buy at least 1100 -1200 w to keep your hardware safe and healthy.
I have 850W PSU running on full capacity for about 3 month non-stop and it works fine 
I did it for more than 6 months on a shitty old cooler master silver psu with no failures, but that doesn't mean its a good idea.
Only psu I've ever had burn on me is a thermaltake, and that was a 750w running at 300w

I`ve also had thermaltake psu that died after two-three power outages. Main two capacitors got inflated like baloons.... Avoid thermaltake folks.
If it is was corsair I would say yes, if it was a crappy no name I'd say heck no.
Also if you look at the efficiency curve you want to stay 50%-85% for most PSUs.
I will never go over 85% for safety and efficiency.

I recently ordered a lot of APW3++ and they are awesome. I used the small server with breakout boards before and after using the AWP3++ I will use nothing else. very low noise, very very low heat compared to the server PSUs.
$105 for a 1600W 94% efficiency PSU is the best you can do.

I have 850W enermax bronze from old dogecoin times when i mined dogecoin, did 900w from wall 24/7 1+year, after year brake s start usin again this, replaced fan runs now 5x rx570 700-800W from wall.
Also i had antminer s2, with enermax 1000W gold, 1050-1100W from wall 24/7, 1+ year, still alive also fan ok.
SS x1250W , 1300W wall many moths gpu script mining, after 1,5y pcie plug melted and rma replaced.
Cheap Nexus 1000W , 850W wall, still alive. 3 years.
If psu can handle it I dont see problem to run max. only psu efficiency will be lower.

I am running 890 watt with 5x Radeon cards in a Corsair 1000 watt gold rated 80+ PSU since January not a single problem until now. Usually a 1000 watt PSU at full load can be a bit max, you should check the back of your PSU and check the total wattage support under the four divided tabs, for example my Corsair says max power will be 1120 watt no matter that the PSU is 1000 watt that is why I am not having problem. Not all PSU-s are like this by the way, I have another Be quiet 600 watt and max wattage support is 576 watt so check your back of your PSU.
I see your PSU says max output power 1000 watt so may be not that safe running 24/7 more than 90% of continuous power.

Yes is super safe.
My case now I got 1000w and use 850w at wall, and another rig 1250w and use 1050w at wall. I live at tropical country, high temperature here. Do you think it is safe?
I would have thought 80 to 85% load is where we try to aim for?
90% is certainly too high.
90% is certainly too high.
80% of the power supply RATING will show as somewhat more than that on a wattmeter, due to the power supply CONVERSION LOSSES.
The RATING is how much power the supply is rated to supply to the load, NOT how much it is rated to pull from the wall.
not safe, you shoud use 80% psu
There are few options that you can choose:
1.) Buy PSU that can run 1200w
2.) Buy Server PSU and add synchronizer
3.) You can power limit the video cards
I do not recommend the third variant.

Did you change the PSU dude?

At that wattage your PSU is not the most efficient, but it is definitely safe to run it. But only if you manage to run it cool, PSUs hate high temperatures.
The PSU is made to run at those wattages and if it burns, it would probably burn even at lower wattages, because it would mean that it is faulty. Also regarding the efficiency calculation the senior guys here are right - I would recommend not to listen the noobies in this thread.
There is no need to waste additional money on 1200PSU and please calculate your return when buying platinum PSU and dont buy them blindly just because somebody else told you. The additional price for it rarely pays off vs a cheaper gold PSU.

you will save some money on it. but you'll burn your entire house. which do you prefer?
The "at the wall" measurement includes power lost to inefficiency in the power supply.
It will COMMONLY be 8-10% or so higher (depending on the efficiency level of your specific PS at the point you are operating it) than what the system itself is drawing.
The power supply "rating" is for how much you can pull out of the PS - 80% of THAT is what you should be aiming for as a max, which will be more like 88-90% when measured "at the wall".
Also, most power supplies get less efficient fairly quickly when you push them much past the 60-80% range.
So its around 880w for 1000w psu and 1100w for 1250w psu. It will COMMONLY be 8-10% or so higher (depending on the efficiency level of your specific PS at the point you are operating it) than what the system itself is drawing.

already got a 500w power supply.
btw one thing I forgot to mention is that those numbers were taken from the energy meter. GPU-Z is showing about 30-40w less for each card. which of these is right when measuring power for the PSU?

Please read from your wattage meter instead of GPU-Z, GPU-Z is just an estimation.

80% is the gold rule.
