Arrow Seasonic X-560 Review

Quote:
Seasonic comes to us again today with another model in the X Series lineup - the X-560. Like the other members of the family, this unit boasts 80 Plus Gold certification, full modularity, and a single 12V rail almost as powerful as the total rated capacity of the unit. It is also currently the lowest powered unit in the line that has a fan, with its 460W and 400W little brothers operating completely without a fan. Let's see how it does.

thanks for the review OW! It looks really good! I may have one also (in 1-2 weeks).

Now we are waiting for the X-760 and X-860

I think it's rather unnecessary to test the standby efficiency at full load. The CQC certification of energy-saving tests standby efficiency at 300mA load. The EuP lot6 requirement is no less than 50% efficiency @100mA load, and the recommended level in ATX12V specs is no less than 50%, 60%, 70% @100mA, 250mA, 1000mA load respectively.

Of course that means you need a more accurate single-rail load tester and a more accurate power meter. You can use some adjustable wire-wound resistors and a precise ammeter (or multimeter) as the load, but a power meter to provide the required accuracy is way more expensive.

Also I want to point out that the APFC circuit is usually deactivated in standby.

Well, I have to agree with the points off for pricing.
Currently everything from 400watt to 650watt (except 460watt which is more)
is priced at the exact same delivered price on the Egg.

I was hoping the 560x would be priced below the 650x. Makes sense.

Instead, the 650X has a $60 combo with a Lian Li case, making it a much better deal.

I'm excited and think the price will adjust itself. This should have a strong market eventually.

If Seasonic can somehow reduce the cost of this psu down to around $100, it'll be a top buy imho. Powerful enough for almost any non-crazy dual video card machine out there, I think it'll probably fit into basically 90% of the setups. Definitely one of my top picks for my next personal main computer.

Looking at the interal components it's pretty obvious that the 400-750W lineup is very similar ... so expecting a big price difference between them is unlikely and a bit unrealistic.

Number of produced samples is not going to get up like the S12II platform (in Corsair/Seasonic as well as in a bunch of other brands) so it's very unlikely to get a big price cut down in that direction too.

This is not a simple layout and it's not meant for 90% of low/mid-end setups, so it's price probably isn't going to be popular any time soon (talking about years).

Just look at all those Solid caps, big coils and that bunch of Mosfet's ... those aren't coming cheap and with that bundle and built quality ... it's meant to be expensive.

That's just the thing with high-end ... if you want it, you have to pay for it, and you get what you pay for

Loved the review, Wolfie.

It's interesting to me how the series improves as the Wattage falls in these fanned X-boxes (Wolfie inspires this kind of bad pun). Clever marketing: if the 560 had been introduced first, we would have been disappointed as each successive increase in power produced a slightly less tight control, even if they were fine psu's. Even the Corsair AX-850 (note that it is still an X-series psu), as nice as it is, would have been a further disappointment when seen at the end of a series running from the 560W on up.

I am very familiar with the fan in this psu. This whole series is available from Premier Farnell/Newark. They are all fine fans.

I got the X-650W based on Wolf's earlier review. Glad I did, even though it did not come with Velcro cable ties.

Yes, I agree with the quality. But you need to differentiate by price or there is no need for multiple models. If the only price is going to be $139, then there is no reason to have a 560 watt in addition to the 650 watt.

There is absolutely no reason to pay $30 or 60$(depending on the combo discount) more for the 560 x over the 650!!

However, I agree the pricing will settle out over time. I wasn't looking for $70,
but little over $100 makes more sense than $140.
