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.

Nice Martin, I've been looking at upgrading my PSU (550W ultra) and I only like buying the modular connectors. $200 still seems kind of high, but almost in the reasonable range. I'd like it to be $150 :)Another thing I might be shopping around for is a new UPS, have you guys reviewed any of those recently?

There is a 650W version. Selling for $160 at newegg nowjeffbui - Wednesday, April 14, 2010 - link
$138 at ewiz/superbiiz for the 650w version. I couldn't be happier with it.vol7ron - Wednesday, April 14, 2010 - link
I like the plan for the future though, especially with power supplies since they last long.My guess was that the next upgrade would be 750W or higher, the real goal was to have an 800W PSU and UPS. My machine probably only currently uses 350W, but I like to have headroom, especially since I keep adding HDs and will probably take advantage of more PCI slots in the future.

HX650 or HX750 (both are modular)HX650 is $120 at NewEgg, I have it... quiet and works well. Reviews show it to be 80+ Silver. but Corsair chose to be Bronze as their own testing (under very hot conditions) didn't qualify for Silver... Kudos to Corsair.

Sorry..my bad. Corsair PSU is Silver...almost Gold.One important thing about the HX650 and HX750 PSU is that they're just shy of 90% effecient at a VERY wide range of loading.
True, the Seasonic unit does do better at PEAK efficiency (if using 220v) by a few %, but if you're actually going to use a 750W PSU at any other load than this, the Corsair will save you $$ upfront and in the long run with lower power bills.
My $.02

HX650 is bronze...nothing more than bronzeHX750 is silver and was originally awarded Gold by 80plus.

Are you a bot or something? Take your stupid Corsair fanboyism and shove it....!!Souka - Thursday, April 15, 2010 - link
Wow... nice post...piroroadkill - Thursday, April 15, 2010 - link
The HX650 IS a Seasonic design, and I think, by looking at it, the HX750 is a Channel Well design. Regardless, Seasonic was also the OEM for the HX520 and HX620. Seasonic make damn fine power supplies.
