Voltage Regulation and Quality
| +3.3V regulation | |
| Load | Voltage |
| 10% | +2.24% |
| 20% | +2.00% |
| 50% | +1.42% |
| 80% | +0.80% |
| 100% | +0.30% |
| 110% | +0.08% |
| +5V regulation | |
| Load | Voltage |
| 10% | +0.80% |
| 20% | +0.60% |
| 50% | -0.12% |
| 80% | -0.70% |
| 100% | -1.29% |
| 110% | -1.40% |
| +12V regulation | |
| Load | Voltage |
| 10% | +2.80% |
| 20% | +2.66% |
| 50% | +2.30% |
| 80% | +1.97% |
| 100% | +1.49% |
| 110% | +0.54% |
Results are measured under room temperature using 115VAC. +12V starts very high since the tests are conformed to ATX standards. As expected, the 12V rail shows low drops and handles up to 41A as well. +3.3V and +5V are well regulated and not too weak. 5V in particular is very stable with only a small difference between 10% and 110% load.
Ripple and Noise
| +3.3V ripple quality | |
| Load | Ripple and noise |
| 10% | 7mV |
| 20% | 9mV |
| 50% | 14mV |
| 80% | 16mV |
| 100% | 18mV |
| 110% | 22mV |
| +5V ripple quality | |
| Load | Ripple and noise |
| 10% | 6mV |
| 20% | 7mV |
| 50% | 8mV |
| 80% | 11mV |
| 100% | 19mV |
| 110% | 21mV |
| +12V ripple quality (worst rail) | |
| Load | Ripple and noise |
| 10% | 9mV |
| 20% | 10mV |
| 50% | 14mV |
| 80% | 22mV |
| 100% | 25mV |
| 110% | 29mV |
Maybe we should stop measuring ripple and noise for Seasonic products since the results make their opponents angry. We've used up all of the positive words in our vocabulary in other Seasonic articles, so we'll just repeat what we said in the X-460FL review: The voltage quality is absolutely flawless. Small transients are no big deal for 3.3V and 5V, and +12V hardly has any noise at all. In short, this is an excellent design.

This is a decent PSU but I'm not a fan of modular cables for PSUs and this PSU is over-priced IMO.ckryan - Wednesday, March 23, 2011 - link
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).erple2 - Wednesday, March 23, 2011 - link
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.Termie - Tuesday, March 22, 2011 - link
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?Martin Kaffei - Tuesday, March 22, 2011 - link
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!Uwanna - Tuesday, March 22, 2011 - link
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 ;)MrS
