Appearance, Power Rating and Fan

The PSU has a black finish and honeycombed ventilation holes. There is no typical fan grill but the casing has many holes punched in it. At 160mm, the case is moderately long. As usual these days, there is a power switch next to the mains plug. Because there's a fan for cooling, this PSU has fewer ventilation holes than the X-460FL. Modular cables can be mounted on the connector panel at the front, and as usual Seasonic's overall build quality is very good.

Seasonic still believes in powerful single rails. On +12V this PSU can deliver nearly the full power since step-down-converters are included for the smaller rails. +3.3V as well as +5V are rated at 125W and/or 25A maximum load. Both have the same ratings as the ones from the older 750W version. That would mean the same kind of components are used here and the voltage drop should be low. At 3A, 5VSB is relatively powerful as well.

The San Ace 120mm 9S1212F404 has seven fan blades and ball bearings; it is not PWM controlled. There is a shield to direct airflow so turbulences near the ventilation holes are eliminated. Owing to the low rotation and passive mode under 20% load, the fan shouldn't wear as much as other fans do in actively cooled PSUs.

    This is a decent PSU but I'm not a fan of modular cables for PSUs and this PSU is over-priced IMO. Reply

    If you're not a fan of modular cables why would you even consider a COMPLETELY modular PSU? There aren't many of them on the market, only the Seasonics and the Corsairs (that are Seasonics). Reply

    What price is some basic peace of mind? While I've never had a power supply blow up and damage any of my components, I've also never bought the $30 specials, either. I see this as more of an investment to the future.

    This PSU (like all high quality ones) has very good voltage stability (ripple plus total), which is the one thing that a PSU is supposed to provide. All of the other stuff is completely superfluous.

    Also, I think you're going to find that there are no other 80+ Gold certified PSU's that cost anything appreciably less.

    Though I do agree, I'm not a fan of modular cables - I would imagine that you'd get better voltage regulation if the cables weren't modular (a little bit better, at least).

    Plus, it's only $130.

    I'd go with the PC Power and Cooling Silencer II for $100. Reply

    I've always been a bit confused about the pricing of this model, which has been out for a while now. It's very close to the x650 in price (at least when the x650 is discounted, which the x560 never seems to be). Is the x560 actually higher quality than the older x650/x750 models? Reply

    It is.

    Well, not much. But the advantage is they have chosen better transistors. In addition the heatsinks for those SR transistors are larger now and the position of some components is different.

    Fine tuning.

    Thank you, Martin. It's great to be able to ask the experts questions! Reply

    I did purchase the X850 instead of the X560 in this review.

    Once I saw the pictures of the internals on another website review I knew this was the one for me.

    "This is basically an 850W PSU that doesn't always run the fan."

    surely not 850W ...

    Sure it is. That's the whole point of this sentence ;)
