     Not so long ago, we took a close look at a new offering from Corsair, the VX550. Since then, the folks over at Corsair haven't been sitting around doing nothing, and today we're looking at the proof of that - the brand new TX750. This wee beastie is the first in a new line of power supplies from Corsair that promise to take over the high end sector of Corsair's offerings for a little while. Will it live up to the lofty standards set by the VX and HX lines? Me, Oklahoma Wolf, and my good buddy Madmat are going to find out today. Come with us as we delve into a world filled with transistors, coils, capacitors, and goblins.

Ok, no goblins. Technically they're called thermistors.

     First things first. Here's a box. A lovely box. A large box. Yonder box immediately promises us a world of coolness within; like a 750W energy efficient, quiet, cool, power supply capable of a whopping 60A on the 12V rail.

     But this is a box of many sides. Here, we see the bottom of the box, which features a quick blurb on how cool the contained PSU is, in no less than three languages. Those languages are English, French, and Spanish. No Klingon, much to my dismay.

     The back of the box. Here we see some big promises being made in several bullet points, again in three languages. Just some highlights from that list:

  • Guaranteed to deliver rated specifications at 50°C
  • 80%+ energy efficiency at 20%, 50% and 100% load condition for less heat generation and lower energy bill
  • Dedicated single +12V rail offers maximum compatibility with latest components
  • High quality Japanese capacitors provide uncompromised performance and reliability
  • Powerful +5Vsb rail with 3A rating
  • Compatibility guaranteed with dual-GPU configurations

     This unit certainly promises a lot, doesn't it? I can't wait to see how it does. Neither can the beavers outside. Hang on a sec - I'm just going to go chase them away. Y'all can have a look at this chart while I'm away from the keyboard:

Corsair TX750W +3.3V +5V +12V -12V -5V +5VSB
30A 28A 60A 0.8A N/A 3A
Max Combined Watts 180W 720W 9.6W N/A 15W

     Man, those beavers can really move. Where was I? Right, the table. As we can see, this unit claims that we can hit 720W just on the 12V alone. That's quite a bold statement. But what also impresses me somewhat is the combined 3.3V/5V rating. At 180W, this unit should also be strong enough to power Grandma's old Pentium III based rig, as long as you don't mind wasting the better part of this unit's potential. The crossload tests should tell us how well it can do that. Let's open the box.

     The first thing we see after opening the box is the owner's manual, a 39 page work of obsessive compulsive translation that features operating instructions in no less than eight languages. But, still no Klingon. Beneath the owner's manual is a thick piece of foam that protects the PSU itself. No bubble wrap on this monster.

     Neat-o! Another PSU cozy, this time in black. Let's unpack the box and see what's in there.

     Here we see the box contents all posing for the camera. We have the power supply itself, a 16AWG line cable, and a little bag containing an even smaller bag of black screws, a case badge, and some black zip ties. But no Klingons. Ok, I'll stop with the Klingon stuff now, just don't shoot me. I'll just take off this here twist tie and arrange the cables so you can see them and... wait a minute, what's this?

     Looks like shipping damage. Only thing is, this unit was packed so well you could probably use the box to ship Mom's good china to... well, China. So, methinks we're looking at an isolated factory boo-boo, as review sample #2 does not feature such "aesthetic enhancements."

     Ah, here we go. And now, another table. Uh-oh, the beavers are back. Son of a... now they have torches! Time to get the hose. This could take a while... I'm just going to put the table up and then turn this over to Matt for a while.
