Does anyone know exactly what the difference is between this oder generation of PSU and the newer ones.

You would think the newer ones are better. But that isn't always the case. They have slightly different components. In what way exactly are these newer components different?

Anyone know?

* Larger/more/better heatsinks
* Better voltage regulation, ripple, and such
* cleaner PCBs redesigned with the benefit of time vs the first gen X-series

maybe other pluses but afaik it's all improvements on the X-x60 vs the old X-x50 units.

For pictures of the internals see page 4 of the JonnyGuru reviews.

oh and "ferky" on the forums at JG listed these differences between the 560 and 650. Go to the seasonic website and compare the 560 to the 660 to see how they compare if the 560 to 650 comparison confuses you.

* X-560 has few cm longer cables than X-650, 2x PCI-E 6+2 (X-650 has 4), 1x 3,5" floppy (X-650 has 2), 1x 8pin EPS12V (X-650 has 2 + 1x 4pin). 5x 5,25" Drive connector (X-650 has 8 )
* X-560 has a bit stronger fan (difference is 200-300RPM @12V), but probably not louder (because the PWM kicks in)
* Transient stage is a bit rearranged (positions of MOV, thermistor and fuse are "hidden" behind the relay)
* Heatsinks on the primary stage are colored in orange/gold on X-560
* PFC Mosfets on the X-560 are assembled in a TO-220 case which has an substantial advantage over TO-220FP (FullPak) in X-650 (in aspect of power dissipation).
* Mosfet trasistors on the switching section of the X-560 have a bit lower typical RDS(on) then the ones inside X-650 (which has a bit powerfull ones).
* PWM controller (CM6901) on the X-560 is no longer placed on the main PCB but on a small daugtherboard (opposite of the X-650).
* The +3.3/5V secondary Mosfet transistors in X-560 have a lower RDS(on) and have higher current limits on high temperatures (and also higher peak/pulse values).
* Some of the electrolytic capacitors on the secondary have higher values in X-560 (than the ones in X-650).
* Secondary +12V Mosfets in X-560 have better heatsinks (lower °C/W) than the ones in X-650.
* The PS223 monitoring integrated circuit in the X-560 has a bit of a help from a couple of LM393 Voltage Comparators (which isn't the case on X-650).
* Some smaller transformers are different between those two PSU (nothing too important).

folowed by the comment "all those improvements are really not important (except maybe for number of cables/connectors in X-650, if they are needed)."

Short answer is buy whichever is cheaper unless you want to buy the latest and greatest in which case get a x60 wattage.

I was planning on the X-560, but at $110 shipped the X-650 is hard to pass up.

The plan was for a i5-2500K with a GTX-560Ti. Sure, the X-650 is more than enough to power that, and sure, it would have been cool to match up the model numbers on my PSU and GPU, but I don't know that its worth $20 to get that.

Can someone tell me why I shouldn't buy this PSU right now?

I can't think of a reason I wouldn't want to use the X-650 in my system so I'm having a hard time thinking of a reason for you not to buy one.

I wandered around the interwebs looking for a comparable setup - Tom's tested this card using a i7-2600K based system and saw ~265W while gaming. So, neither PSU would hit 50% loading and the fan might not turn on for either. :D I'd go for the bargain.

Since you two utterly failed to convince me otherwise:

I've just ordered a Seasonic X-650.

This is the first official part to be ordered for my new build. Now I just need Fractal Design to give me a chance to see if I want the Arc Midi. Then I'd be pretty much ready to go on all the rest.

What's the latest about complaints of buzzing on the Seasonic X series. Are people still having that problem on newer units?

Ordered. Thanks!

Update Mar 31: It arrived this week, and I have to say, the packaging for these is just over the top. Velvety PSU bag? Two-pocket bag for the detached cables? Hopefully it'll work well. Gotta love Newegg -- ordered on a Saturday night, and received it around noon on Tuesday.
