even low quality components gets a good life span if you use them at half the rated spec and in cooler environment.

an example is LED bulbs i own Philips, that have average lifespan of 1 year (heavy use), i had a chinese (forgot the brand), but due to aluminum heat sink to the electronic component, lasted for 4+ years (heavy use).

hehe that's why you don't throw old cards, you stress test first with a bunch of 290x and then run it light and cool.

even branded quality PSUs breaks down due to heat and high load. huge ATX PSU will save you the trouble of dealing with break out boards.

also if it is cheap, it will ROI faster.

There is a big guarantee for branded power supplies up to 10 years, although these branded power supplies broke down for me. But since service centers in my country do not repair them, the sellers returned the money to me for the purchase. Sometimes it turned out to buy a similar power supply cheaper.
There may not be a problem with Chinese power supplies, but now it is better to buy a proven branded PSU, because they are cheap.

Here is the math,

1300w branded psu ~ 300$
2600w chinese cheap psu ~ 150$

The 1300w can be used for 80% load, that's ~ 1000w, the 2600w used at 50% is 1300w.

Warranty is already priced in the retail, at ~300$ you already bought the 10yr warranty. For the cheap psu, you don't need to wait for 10 years for ROI.

I would only use the cheap psu on old gpus, when upgrading use the branded on new cards, move the old cards to the chinese psu.

I agree with you dear friend. I have 3 chinese psu 1600w cost me 40-50$ each used. I loaded them 900w and they are working since 2017. They are not bad but i saw there is rubbish chinese psu too.1st of all when you get pay into your hands it must be heavy. Only this reason i bought these cinese psus they are heavy.it is best way i guess to understand if psu is good quality if you dont have nothing to measure.

I also have not always used branded power supplies, and I am ready to confirm your words that they work well, but they have the disadvantage of lower efficiency and they consume more electricity from the outlet. Another downside is that these power supplies are harder to find repairs if they break. But on the other hand, there are now a lot of good and inexpensive power supplies at low prices.

pin burned surely warranty wont accept it, neither gpu or psu, sadly some psu cable quite bad doesnt hold 300w of power.
mostly the cable socket or psu socket get burned. and now gpus seems using under wattage configuration lol Grin

Other mathematics:
2600w chinese cheap psu ~ $ 150, but you need to take into account the real allowable load on this PSU, and this value can be in the range of 1300-2000 watts.
Excellent power supply Corsair 1000 watts after 3-4 years of use ~ 100 dollars.
If there is a breakdown, then I need 1 or 2 trips out of town to find the cause of the breakdown, and then buy the necessary components for repair. 2 trips is an expense of 20-30 dollars.

That's why I've bought Corsair 600W PCIe 5.0 cables for my 4090 gpus.

Share a link to the cable.
Branded cable is good, but 200-300 watts for one connector is a lot if the load is constant, like in mining. You cannot leave your mining farm unattended for a long time, and in the summer you will need to monitor your video cards more closely.

600W PCIe 5.0 12VHPWR Type-4 PSU Power Cable - https://www.corsair.com/us/en/p/pc-components-accessories/cp-8920284/600W-PCIe-5-0-12VHPWR-Type-4-PSU-Power-Cable-cp-8920284
RTX 4090 - Replacing 3x 8-pin Adapter with 600W PCIe 5.0 - https://www.youtube.com/watch?v=zOTo9_xekzg

Thank you. But of course it is very expensive. 3 cables for 6 GPU headers on the power supply will cost about half the cost of the power supply Sad

Nvidia assholes.
Therefore, I will choose other models with 8 pin power connector or AMD video cards that do not change the power connector.

I paid 25 euros for one cable, the PSU costed 300 euro, so I think it's a reasonable price.

In Russia, a corsair power supply (gold or platinum) of 1000 watts costs 100 euros. But you can buy for 10-20 euros cheaper in bulk.Ii is 3-4 years old, but the warranty for such power supplies is 10 years. For 300 euros you probably bought a more powerful unit, but I can use 2 used power supplies total power 2000 watt for 200 euros.

Yes, it is HX1500i. I have RM1000x on my other rigs.

We always have an inadequate price for such power supplies, and in the season they could cost $ 600, and this is the price of a used power supply. 850 or 1000 watts are the most popular power supplies in this series. For more power, it is better to choose a server PSU.

There are chinese atx PSU with ratings of 3000w, 2000w, they are big and lots of wires. They are cheap, might worth a try--only for old ROI'd cards LOL

I think running them at 50-60% of rated power would be ideal.

Each of these Chinese power supplies has its drawbacks, because manufacturers save on buying quality components. Moreover, if you need more than 2000 watts and 2 corsair power supplies of 1000 watts each do not suit you, then it is better to buy server power supplies. I wouldn't buy cheap power supplies because I don't want to risk a stack of graphics cards.

Much better than an adapter, it eliminates an unnecessary extra connection, but only works with Corsair. Each different PSU needs its own custom
cable to match its pinouts. PCIe 5 PSUs are still rare since only Nvidia GPUs can use them.
