A defect that is useless to take under warranty
15 May 2026 
A month after assembling the PC with 9070XT and this PSU, random "crashes" started happening. Both monitors would simply turn off, and the system unit wouldn't indicate any problem, forcing a hard restart. The effect is exactly like if you disconnect the graphics card from the motherboard or one of the power cables on the graphics card while the PC is running.

I spent several weeks trying to fix it on the software level, trying everything I could. I also disassembled and reassembled the computer, hoping to find a cable that was improperly connected. I even bought a new powerful UPS with a battery backup that allowed the computer to continue working for almost an hour during power outages. All to no avail.

I sent the PSU and the graphics card for diagnostics under warranty. Both were returned without identifying any problems. Only the graphics card service center provided a documented report with their name and address, and it was evident from the condition of the graphics card and packaging that something had been done with them. As for the PSU, there was no indication of who, where, or what had been done, or if it was even taken out of the box.

Having no more faith in the warranty's value, I replaced the PSU itself and bought a BQ Dark Power 14 850W. PROBLEM FIXED. It has been working for 2 months now, even under more load than before, without any issues.

Most likely, one of the 8-pin cables in the set is faulty, and there is no spare included in the package; I need all three provided for the 9070XT. Official replacement cables are not available on the market, and it's better not to risk valuable equipment with third-party cables.
Easy to install, quiet fan.
A defect, I'm not sure how typical it is for this manufacturer. The service center did not find any defect during diagnostics, so I waited for several weeks to no avail, and the money for delivery went to waste.
Oleksiyuse PCCooler YN1000 few months
for ~4600UAH probably the best PSU

Built on the Andyson P32 platform. It features Japanese components and a full-bridge topology. It has a fan controller for better regulation, unlike other coolers that constantly turn the fan on and off based on the sensor.
ATX 3.1, operates quietly even under high load
Reviews mention that it gets a bit hot under full load.
Oleksandr use PCCooler YN750 few months
