5.0 out of 5 stars excellent quality, July 29, 2010
Amazon Verified Purchase(What's this?)
This review is from: Corsair HX Professional Series 750-Watt 80 Plus Certified Power Supply Compatible with Core i7 and Core i5 - CMPSU-750HX (Personal Computers)
This PSU replaced an OCZ stealthXstream psu and by every regard it's of much, much higher quality. The PSU is very large so if you're not bottom mounting it be absolutely sure your case can tolerate a 10 pound brick at the top. The 24-pin connector cord is extremely long, giving people like me the ability to run it behind the motherboard (cord management) without the need of buying a 24-pin extension. It's modular so you only need to plug in the cords you need. And best of all, it's ultra quiet. I have six 120mm intake fans (3 intake, 1 cpu, 1 gpu, 1 exhaust) and one 200mm exhaust. My computer sounds like a floor vent when the AC is blowing; just a quiet hum of air moving. No whisp, no whine. Right away it was noticeably quieter than the OCZ psu this replaced.

The modular cables are stored in a velcro bag (two standard molex power cables, two sata power cables, and four 4-pin PCI-E adapters!!), the PSU comes wrapped in a velvet satchel, the packaging is over sized, and it's all heavily padded. In the end, Corsair did not cut any corners whatsoever in making this PSU. What you pay a little extra for in price is obvious when looking at and using this item. I highly, highly recommend it.

5.0 out of 5 stars Corsair HX750W PSU, December 23, 2009
Amazon Verified Purchase(What's this?)
This review is from: Corsair HX Professional Series 750-Watt 80 Plus Certified Power Supply Compatible with Core i7 and Core i5 - CMPSU-750HX (Personal Computers)
Pros: 750+ Watts of power on a single 60 Amp rail. I say 750+ because multiple reviews by reputable PC forums have shown the HX750W to be almost virtually identical to its HX850W sibling. I've seen reports of HX750Ws putting out 900+ volts with outstanding noise and ripple values on the line. My system draws perhaps 200 Watts at any given time, give or take, but just knowing that I have the headroom (as well as the efficiency even at a mere 20% load on the PSU, as demonstrated by the 80 Plus Silver certification) is nice. The 7 year warranty and 100,000 hour MTBF mean that this PSU has the potential to(and should, according to the MTBF) run for a solid 11 years. Outstanding!

Cons: Um... help me out here. A PSU from a proven manufacturer with one of the best warranties in the industry and outstanding performance... can't say I see too many cons, at least so far.

Other Thoughts: These newer Corsair HX series PSUs are manufactured by CWT and rebadged by Corsair. That being said, CWT has done an outstanding job with this PSU as far as design and parts are concerned, from what I have researched. Its been reported that just about everything in the HX series' design is more than solidly engineered and constructed. I've owned this PSU for a week now and it's been running almost non-stop and I have no reason to believe it will do otherwise. However, should the unit suffer any failures, minor or catastrophic, this review will be promptly updated.

5.0 out of 5 stars Fantastic Product, but Amazon shipped this poorly., August 10, 2010
By

Amazon Verified Purchase(What's this?)
The HX850 is an outstanding product, works perfect with 0 issues. More than ample power for complete quad-SLI/XFire. The cable management is fantastic, and the packaging of the product from Corsair was outstanding. I gave this item 5 stars for the product, but not for the shipping..

Be aware of Amazon's shipping for this item, I received this product in a box 3x the size of the package, with nothing stopping the package from moving N/S/E/W, the only thing in the box was loose(yes loose) air bagging on top of it. 1 Star for Amazon's shipping.

I pay for Amazon Prime and I have never seen such poor shipping, of all the times though, it is on one of the most expensive items I have purchased here, very unsatisfied.

The ONLY reason the product was not damaged was because of Corsair's fantastic packing job. The PSU is inside a plastic bag, followed by a cloth tie up bag, in cased in 2 very sturdy sheets of foam. The other end of the box is stuffed(nothing moves in this package) with a re-usable and very handy bag for your cables. All in all Corsair did a magnificent job on the product, and the packaging of it. Amazon, however, failed to ship this properly, but thankfully Corsair did their part to secure it.
