Corsair Professional Series power supplies are design for enthusiasts and gamers who demand high performance, high efficiency, the flexibility of modular cables, and unflinching reliability. Designed and engineered using cutting-edge technology, each Corsair Professional Series power supply is built to the highest quality standards, and delivers the features and performance that technology enthusiast’s demand. Corsair Professional Series power supplies are built using Industrial Grade electrical components, ensuring the stable, clean and reliable voltages that are essential for high-end gaming PCs and workstations. Professional Series PSUs are rigorously tested at 100% load and an ambient temperature of 50°C, guaranteeing stability and reliability even in the most demanding, multi-core, multi-graphics card systems.

The Corsair Professional Series HX1050 PSU passes 80 PLUS GOLD certification standards, for up to 90% energy-efficiency. This reduces wasted energy, reducing energy bills, and lowers the amount of excess heat generated, allowing the cooling fan to spin more slowly and quietly. Corsair Professional Series power supplies are built using Industrial Grade electrical components, ensuring the stable, clean and reliable voltages that are essential for high-end gaming PCs and workstations.

Corsair Professional Series power supplies boast an innovative semi-modular cabling configuration that uses low-profile, flat modular cables, which reduce air friction to help maximize airflow through the computer chassis. The modular design also simplifies installation as it allows unprecedented flexibility in utilizing only those cables which are needed.

87.5 Amp Single +12V Rail The HX1050 is ideal for gaming and enthusiast PCs with the latest CPUs and multiple graphics cards, thanks to the dedicated 87.5 Amp single +12V rail, and 6 x PCI-E graphics connectors. The immensely powerful single +12V rail also simplifies installation, as you don’t have to worry about which +12V rail is connected to each component in your PC, as with multi-rails PSUs.
Advanced DC-DC Circuit Design The use of advanced DC-to-DC circuitry means that energy losses due to AC-to-DC power conversions are eliminated, increasing energy-efficiency and performance.
80 PLUS GOLD Energy Efficiency The HX1050 power supply delivers up to 90% energy efficiency under real-world load conditions and passes 80 PLUS GOLD certification. This means that less power is wasted as heat, helping to keep the PSU cool and reliable, in addition to reducing electricity consumption and energy bills.
Comprehensive Modular Cable System The HX1050 features a comprehensive modular cable set that caters for tall chassis and modern, high performance gaming PCs. The cable set includes 6 x PCI-E power connectors, and 2 x 8-pin EPS12V connectors.
Low Noise Design The high energy-efficiency, which results in less electricity wasted as heat, means that the HX1050 requires less cooling than more inefficient PSUs. The ultra-quiet, 140mm double ball-bearing fan automatically adjusts its speed to deliver the proper amount of airflow, so high-performance power delivery is not at the expense of noise.
Energy-Efficiency The Corsair HX1050 complies with the ErP directive and has qualified by Intel, which means that the power consumption of a whole system (with an ErP compliant motherboard) in either standby or off mode must be under 1W.

N/A 5/9/2013 6:21:14 PM Tech Level: 4/5 Ownership: 5/5	Rating: 5/5Awesome Product Pros: I've had this PSU for about 2 years now, got it when it first came out and it's still awesome! I can barely hear it, likewise other users have indicated that it squeaks. I have yet to notice anything like that! Works wonderfully, love how it's modular. Comes with lots of cables for expansion. Good overall PSU for the price. Cons: None, awesome PSU. Other Thoughts: i7-2600k OC'd @ 4.8ghz Asus P8Z68-deluxe Corsair Vengeance 16GB DDR3 Ram EVGA GTX 660 Ti SC Corsair Force GT 120gb SSD Hitachi 1TB 64mb cache 6gbps HDD Did you find this review helpful?

N/A 5/1/2013 5:31:51 PM Tech Level: 5/5 Ownership: 4/5 Verified Owner	Rating: 4/5Sqeeeeeeeks By Pros: Delivers the juice and laughs about the 850 watt peak load I use while gaming or encoding. Plenty of room for expansion and the modular cable system is great. Did I mention this PSU is a great value and is high quality and nice and stable even at full rated load. Cons: Does make a high pitched noise, some users say they can hear it all the time, I only hear it when the side of my case is open. Many users have reported DOA or dead within 3 months, though my unit seems to be great so far. Other Thoughts: I run a huge system, on an AMD FX platform with ATI cards and loads of drives.

N/A 4/29/2013 6:02:33 AM Tech Level: 5/5 Ownership: 3/5 Verified Owner	Rating: 1/5Not Recommended Pros: Product is very beautiful to look at and comes with a PSU velvet storage bag. Cons: Stopped working within 5 seconds of first power cycle. Fried CPU and most likely Motherboard too on that same first power cycle. Sent it back (RMA) and will never consider Corsair products again (sorry). Other Thoughts: I cannot recommend this product based on my experience with quality. Did you find this review helpful?

Mike 4/14/2013 10:33:31 AM Tech Level: 5/5 Ownership: 4/5	Rating: 4/5It's A Good PSU Pros: Did not purchase this from Newegg. It's a great power supply, real work horse. I actually only need a 800W, Actual System Draw is 690W according tot he calcs, 600W is the peak i've managed to obtain. I like my PSU's to last forever, so therefore I got this one. It's been working great for the last 2 months... Cons: The 5V rail after 2 months of use has gone from 5.1-5.2V (first after purchase test) to 5.6-6.1V (for the last week). So now I am in the process of having to RMA it. I'm disappointed that the 5V rail has degraded so much in such little time. I'm most likely going to purchase another one, RMA this one I currently have, and have it as a spare just in case. I really can't go too long without this computer as this is the main computer used for my business and managing my servers remotely. And games...which I don't really get to play hardly ever. Other Thoughts: It's great. If it isn't 80 Gold, don't but it. Corsair makes some really good products. I've installed a total of 19 Corsair PSU's in the last month for my customers (from 500W to 1100W) and they are all running like champs. It's one of the few products I push to my customers from the same manufacturer. They have decent customer support, even though the technical support sounds like the guy is reading from a screen and doesn't know what "I already did that" means (it's happened to me a couple of times). It's a great product, just remember to test the voltages before you connect it. Did you find this review helpful? Thanks for the valuable feedback you provided!

More sata power than I could ever fit in my case. Cons: None Other Thoughts: Replaced a 700w raidmax peice of junk.. couldnt power 2 6850s without some adapters.

Log 1/31/2013 11:51:03 AM Tech Level: 4/5 Ownership: 3/5	Rating: 5/5Awesome! Pros: Amazing 1050 Watt Corsair Powered Cool Sticker Many features Supports SLI/Crossfire Cons: Maybe make the Sata connectors a bit closer, had some trouble connecting my hard drives, because mine are close. Not taking anything off though. Other Thoughts: I bought the 80+ silver one, (not on newegg) at a local computer store. And I love mine. Nothing wrong with it, in my opinion. Simply amazing.

N/A 1/18/2013 3:30:50 PM Tech Level: 3/5 Ownership: 5/5	Rating: 2/5Great if it lasts more than 3 months Pros: Looks great Doesn't feel cheap. Tech support is good. Cons: Only lasted a year (first one) Price You pay shipping on RMAs Other Thoughts: Had bought the HX1000(I don't think they are made anymore) and it was solid running for about a year, and then it started to shut down. Becoming more frequent it eventually gave up and died. I had no problems getting it RMA'ed through Corsair. Other than the fact that getting it shipped cross border to their OC was expensive. I received the replacement within a little over a week, which was nice. However, after only 3 month this one has died too. I've decided to not RMA this one and go for something different. I managed to get a good deal on an XFX 1000W platinum. (XFX is manufactured by Seasonic) I find Corsair products to be of good quality and will stick with their RAM sticks, but I won't be buying another Corsair (Channel Wise) manufactured PSU ever again.

ChicagoMan 1/14/2013 8:42:59 AM Tech Level: 5/5 Ownership: 5/5	Rating: 1/5This Was an RMA replacement Pros: It worked for 2 months Cons: This unit was an RMA replacement for the THX 1000. The problem seems to be with the circuit that controls the 12v rails when using an ATI card. I originaly had the 4872x2 which randomlly crashed my PC, so then I purchased the 5870 with the exact same result. Talked with XFX and ASUS and replaced graphics cards, and RAM, even considered the processor and MB but really didn't make sense since the problem was the graphics card. I placed a low end graphics card that only used 6V and it worked great, but the moment I needed the 12V I would ger random crashes. If you are using an ATI card I would recommend against getting this PSU as I have now owned two that will not play well with ATI cards. I am replacing this unit with an XFX PSU in hopes that their PSU will work with their graphics cards Other Thoughts: Corsair is obviously using a control circuit for the 12V power distribution that does not work well with ATI cards. I am not sure if this is a known issue, but it is certainly one that I am now well aware of. 0 out of 1 people found this review helpful. Did you? Thanks for the valuable feedback you provided!
