Picking out a psu for new project

I was wondering if any one has used the OCZ ZT 750w psu? http://www.newegg.com/Product/Produc...82E16817341052
The feature set seems to be right on the money for my new project that I will be working on later this month. I remember somewhere hearing that OCZ psu's are actually manufactured my seasonic, is this true? I am wanting to switch to a modular psu from my Kingwin MK-650 http://www.microcenter.com/single_pr...uct_id=0345546 and would like to keep around the same price as the OCZ (also having the 2 4+4 pins should be nice for the Crosshair V that I am getting). Any thoughts, comments or observations?

Also I did hit up the psu calc and it said a min of a 402w psu for:

Crosshair V motherboard
phenom 2 x4 975 (with a tasty oc)
custom water loop featuring a 240mm rad and a D5 vario pump
1 7200 rpm hdd
1 optical drive
CM Storm trooper case
Gigabyte HD6850-oc
2 120mm led fans (made by cooler master and come with the case)
2 120mm non led fans 1650 rpm

No. It's not true. That unit is made by Great Wall.
It's a mediocre unit. You can do better for the same money.
Review for you.

Either of those are fine. They're basically the same unit.

Ok thanks! I think I'm going to go with the XFX PRO750W XXX Edition after seeing how silverstone converted a multi 12v rail pcb into a single rail by soldering a wire across some contacts. Not to mention the shipping is cheaper and if i get lucky the mir is better (I never can get those things).

You will like the XFX. It is a solid unit. And don't worry. Your unit has a jumper bar soldered on the bottom of the PCB as well.

I found a review that included a pic of the bottom of the pcb and talked about the similarities between the 750w and 1000w. http://www.jonnyguru.com/modules.php...tory4&reid=183 <--650w
http://www.jonnyguru.com/modules.php...tory4&reid=180 <-- 1000w

if you look at the upper left hand side of the back of the pcb of the 650w you will see the same thing that is shown in a close up of the 1000w at the bottom of the page that I linked.

It is not unusual to find a jumper bar/wire on a PSU circuit board. Manufacturers typically use a common PCB between several product lines to streamline their supply chain and reduce manufacturing cost. For example XFX uses the same basic PCB for the Pro series and it has a jumper bar soldered across traces in the area of the secondary. It may not seem elegant, but if you think about it a jumper bar has almost no potential for failure unlike a PCB trace or any of the mounted components.
