X750 - Connectors and Cable Lengths
Since the X750 is equipped with a fully modular connector panel; even the main plugs are detachable. That can be useful for those who don't want to deal with fixed cables during installation, and it potentially allows custom cables (i.e. shorter harnesses) in the future. A sticker above the sockets shows where to attach each type of cable harness. On the left side are two connectors—one 16-pin and one 10-pin—that combine to form the main 24-pin cable. There are two PCIe connectors with two 6/8-pin PCIe connections per harness. 4-pin ATX12V and 8-pin EPS12V are available, along with five sockets for SATA/Molex harnesses. All of the cables are sheathed with a soft mesh fabric, through which you can still see the cable colors.
The harnesses are reasonably long but you'll want to measure on larger cases just to be safe. The 24-pin, ATX12V, and EPS12V are 55cm, as are the four 6/8-pin PCIe harnesses. The peripheral cables are up to 80cm long, with an additional adapter that lets you connect two floppy plugs (15cm). Using all of the harnesses, you get eight SATA and Molex connections, so there's enough for a good size RAID setup with a few optical drives.

I use an HX1000 Corsair PSU in my system, I would have bought this unit because it's higher quality but they don't make more than 750watt units in this series. Why not?529th - Thursday, April 15, 2010 - link
The 750 should put most machines today in the most efficient part of the efficiency curve.With the 650 model you hit the highest efficiency of 92.1% between 269-292; and most systems draw around there when gaming. My i7 920 (stock clocks,) 5870 (stock clocks,) 6g 1333 1.6v, was right between there; and I'm glad I chose the 650w model. Even then if you are doing a little overclocking, you stay within the 90 percentile between 134w - 588w which is solid. So given the 750w model you can assume another 100w added to the 588w and you'll still be in the 90 percentile which is darn good!
Of course, not all machines are running stock clocks.

JonnyGuru did a great review on the[rul=http://www.jonnyguru.com/modules.php?name=NDReview...]Seasonic X-650[/url]. The ripple suppression on these things are top notch. Check out page 3.Isn't he still a mod here?

Got the 750 on ebay for 148 (with shipping) after cashback. Was quite a steal considering the MSRPpower draw at the wall went from 153 to 123 at idle. Quite the change from my old aerocool zeroDBA.

Are power supply manufacturer’s going to be moving towards switching topology between lower and higher loads?Given the trend in CPU’s/ GPU’s to use power gating and hard disk controllers spinning down disks when idle, are we going to be seeing power supplies which provide high efficiencies in 50w-150w and 400w+ in the case of a 750w power supply.

I put together a new system using my old HX620 and I was getting squealing from various components. I decided to take a chance and try a new PSU and I knew I wanted one that was more efficient. I'd seen some of the pics of the inside of the X750 and fell in love with it, it's so clean. So I coughed up the money to get one, and luckily it was worth it because all the squealing noises went away. And it's also drawing less power according to the kill-a-watt tester I plugged it into. So, it's pricey, but if you want a good PSU, this is it.Salsoolo - Thursday, June 3, 2010 - link
thats a fine psu90+ all over over, thats amazing

I don't suppose any one could offer some thoughts based on my needs outlined in this thread of mine?http://www.jonnyguru.com/forums/showthread.php?p=6...
Much appreciated if anyone can!
