It's too early to evaluate. a couple of months in the work. but the supply is really rich. all in bags. the turntable is quiet. module .plus version was with tester. Semi-passive cooling. 650w cost 120€. Sisonik. cooling mode. 10 years warranty. filling . 80+G It's too early to say. I hope he can be trusted with a computer.  starpom: use Seasonic FOCUS GX-650 few months |
Official BP. The equipment is generally royal, bags, boxes, sachets)) To be honest, I did not expect this from a PSU for 120 bucks. The wires are long, those for additional power are also separated (6 + 2 or 8) All in an iron braid, in short, I'm delighted). What is the button to disable or enable passive cooling. I didn't know about this at all. I measured the efficiency (output) in the load, it turned out 88% when applying 500 watts! It is not audible at all at low and medium loads, at high it is audible, but weakly. Doesn't overheat. I looked at the layout under the set, everything is very neatly done. I found a disassembled photo on the Internet, everything is on Japanese spare parts, almost all polymer capacitors. There is also a sense of heaviness. and something noble. I put it in the computer and I’m 100% sure that it will plow for more than one year. I hope my review will help someone decide, but I'm very pleased. The workmanship is top notch. Good fit and attention to detail. Long cables + separated by pins. Excellent efficiency. Quiet. No Anton Ch: use Seasonic FOCUS GX-550 few months |
The same filling is in Antec EA650G Pro. Quality. Heavy (but that's a plus). |
