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.
