My corsair vx450 has a main large japanese capacitor rated at 105 degree C.
Good supply. I have 3 of them, and I have yet to have any power-related problems.
I've noticed this being advertised as a selling point on other PSU from fortran to seasonic to antec
Is this a good selling point or marketing? Is the primary benefit longevity or something else?
Some Chinese companies made bad capacitors for years. These would lose electrolytic fluid or swell. Either way, they stopped working early. So, longevity of they whole computer system was effected.
Most power supplies are rated for their "750 watt" power at roughly 25 Celsius. Inside a hot PC, the temperatures are usually over 40. Hardwaresecrets
is the best for power supply testing, now that SilentPCReview is not pumping out reviews at a fast pace. So, performance is effected.
Anyhow, I removed the original Adda fan with a clicking noise and swapped it for a S-flex 120mm Scythe, and use speed fan to spin it down to 50%, or about 5 volts. Hopefully the PSU will last long. It is virtually inaudible.
My pc uses nvidia 7600gts fanless and core2 duo 1.86ghz not overclocked no games.
Why not return the PSU for a free replacement?
Yes, the point of the 105 capacitors is that the supply will last at high temperatures, and deliver most of its rated power as temperatures increase. Your computer may not produce much heat, but good capacitors only add a couple of $ to the price of each PSU.Hardwaresecrets
always tears open a power supply, and tells you about each part that is being used.
