Topic: I'm suspecting my 1200w power supply (Read 170 times)
I would also recommend that you measure the actual watts at the wall. Efficiency of power supplies play a role that cannot be ignored. If we do a rough calculation, an 80% efficient 1200W PSU will draw around 1500W at the wall [1200/0.8]. It needs to provide 1200W to the inside of the PC but will draw more power at the wall to do it. The more expensive PSUs like the Corsair AX1200i that is 80Plus Platinum is much more efficient than a normal 1200W 80Plus rated PSU. Not to say this is your problem but it would be good if you can invest in a proper PSU where the watts at the wall is closer to the internal rated watts. Furthermore, get yourself a watt meter at the wall. You plug the PSU power cable into the watt meter and that into the wall. It then displays the actually watts at the wall on the plug and you just leave it there. As your loads increase, you will see the digital display increase. Lastly, make sure you put a UPS between the wall and the PSU, just to take out any fluctuations in power that may damage a PSU, because in the end such a fluctuation could have damaged your current PSU.
The bulbs flicker, are these house lights or computer lights? I wouldn't suspect a computer PSU
to affect house lights. If the lights flicker at 60Hz (or whatever you AC is) it's an inverter issue.
If the lights are browing out your generator is overloaded.

Where are you located where it’s cheaper to mine with a generator than with electricity. Given how high the price of fuel is lately I am guessing you must live somewhere in Iran where fuel is like $0.10/L for you.
Either way. Like the above posters have said. Not all generators are rated for this job. Many generators are for construction equipment like power drills which don’t need as clean a signal as a computer. You need to get a different generator.

It can also be the type of generator. You want to use one with a digital inverter so you get clean power. A lot of generators provide less than clean sine wave power. They are fine for running a motor or equipment like a drill…but electronics will be affected by their less than a pure sine wave.
This can lead to problems and even damage to electronics expecting cleaner power.
Maybe this is the real issue here? My generator has no digital inverter and I can't figure out if it's a pure sine or not since I'm not qualified personnel, it's been over 4 days that I've been using the gen with this mining rig and it works perfectly but the light still flickers. This can lead to problems and even damage to electronics expecting cleaner power.
The flickering lights is a clear sign of it being dirty power. You can simply install a UPS (power backup) with sufficient wattage and plug it into generator and psu into it and get clean power. Or an AVR (automatic voltage regulator).
Here is an article about what why and how to resolve.

This can actually be a stupid question but if it is do pardon me, I think my power supply 1200watt is faulty, its akasa brand the thing is whenever I use the generator to power the power supply my bulbs will start flickering/shaking like unstable current, at first I thought it was the generator but I powered a pressing iron on it with takes 1400watt and the light/current was very stable, I also use another power supply it's stable too, is the 1200watt power supply faulty?
A generator of 1400W is not enough you need at least one of abt. 2000W to account for the the power draw fluctuations of your psu as it can peak at over 1400W.
Okay some generators put out a square wave and not a sine wave
and some psu's are fuck you I want a sine wave not a square wave approximation of a sign wave.
And a 1200 watt psu running against a 1400 watt gen is not good.
more like use a 2000 watt gen.

the one above is a 2000/2300 and is sine wave rated
it is likely the bare minimum you need
"About this item
2,300 Peak Watts/ 2,000 Rated Watts
Capable of up to 6 Hours of Operation at Half Load on 1.18 Gallons of Fuel
Compact Suitcase Design, Weighing Less than 47 lbs for Easy Handling
Quiet Operation (59 dB) make it Virtually Silent from just 10 feet away
Stable Sine Wave Technology provides pure, safe electrical power for powering and charging laptops, cell phones, and other sensitive electronic devices"
the key points are
1)stable sine wave tech
2) 2000 constant 2300 peak watts
I have this gen below
https://www.amazon.com/CRAFTSMAN-Craftman-1700-Inverter-Generator/dp/B07P5XRQPR/ref=sr_1_3?
it is pretty much the same as the ford it runs just about anything up to 1200-1300 watts
and some psu's are fuck you I want a sine wave not a square wave approximation of a sign wave.

Have you tried another power supply? If not try getting one from your friend just to confirm, if the light from the generator is now stable then that power isn't working very well, though if this doesn't happen with grid power then that generator is in bad shape.

Use a power supply testerhttps://aliexpress.ru/item/1005001359834960.html?
I don't have one, so I connect some old hard drives and/or DVD drives to the power supply, connect the green and black wires to a 24 pin connector, and measure the voltages with a multimeter. Tests must be performed on a working 110/220 volt power outlet.
What is the max power output of the generator? Should be double the power you drawing I mean a 2800watt generator is enough to work very well, drop more information to get accurate answer.
