5 out of 5 eggs1st haswell Power sup

This review is from: CORSAIR HX Series HX1050 1050W ATX12V / EPS12V SLI CrossFire 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Wow is it working?!! The fan rarely comes on. No heat no hick up, no bumps in the road on this bad boy. Here is the Lay out for you and you decide.

MSI Gaming 5 mother board
Crucial M.2 SSD 128 gig
WD Red 1 tera
Seagate Momentus 700gig
Intel i7-4790K
2X MSI R9 290X Lightning
Corsair Dominator 1600 32gig
H100i
Corsair Carbide Air 540
It fans up when a load hit her otherwise its off and cool.

Cons: Semi Mod

Other Thoughts: I am a believer that 850 watt is plenty for anything. I went a little further due to the 2 R9's. I think I would of been safe having a 850 in this series if they made it or something close. Anyhow its very very nice.

5 out of 5 eggsGreat PSU

This review is from: CORSAIR HX Series HX1050 1050W ATX12V / EPS12V SLI CrossFire 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: well this is a first time for a corsair purchase and everyone told me they were good, so word of mouth is why i made the purchase first off, well my friends were correct, this power supply unit looks well made to the eye, all the plugs and wires looked proper and not cut short or exposed like some other brands, you get a plenty supply of wiring for your needs for your entire case as well as internal stuff, as well as a case for the extras, as for the power supply itself it is running smooth and very quiet, no noise on startup and no noise upon running and no noise on shutdown and yes it works as it powers everything just fine.........the price i thought was fine for the similar products out there that were for the same or near the same but the quality with corsair might be he way to go ........buy with confidence,

Cons: none so far

2 out of 5 eggsit's a Squeeler

This review is from: CORSAIR HX Series HX1050 1050W ATX12V / EPS12V SLI CrossFire 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: The connection cords where a good length. My EPS and mainboard connector both wrap nicely around the back of the case (Antec 1200) to remain out of sight.

Although it's not completely modular, by the looks of things if you have a system assembled in the last 10 years you'll use the pre-wired connections anyways.

Cons: Coil Whine, Capacitor Squeal, whatever you want to call it, it's **** parts. I searched the box, the website and every piece of literature about this PSU and although I found a lot of "High Quality 105 degree Capacitors" I've not once seen the name "Japanese Capacitors". Irregardless it's got a bad component that is so high pitched it would make dogs howl.

I should have closed the box and sent it back the moment I found the faux felt bag surrounding the unit. (Overcompensating much?)

It does have a 7 year warranty, but here's my dilemma. Do I shut off my computer and repack the PSU for replacement and wait 2 weeks for this one to ship out and a new one to ship in, OR, do I buy that Seasonic that has much higher reviews and request a return on this one and swap it out without the downtime.

Manufacturer Response:

Dear Customer,

We're sorry to hear that you're experiencing coil whine. We do offer express RMA's for those who need their replacements in a hurry, if you would like to get a replacement feel free to submit a ticket at corsair.force.com or call us at 888-222-4346 and we'll be happy to help you.

Thank you,

5 out of 5 eggsMore Corsair Goodness

This review is from: CORSAIR HX Series HX1050 1050W ATX12V / EPS12V SLI CrossFire 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: Stable and power aplenty--cooling fan heard occasionally but no big deal. Nice long cables that reached all destinations within a huge Corsair 900D case. 3rd Corsair power supply I've purchased and nary a problem with the lot.

Cons: Fan can be heard occasionally.

Other Thoughts: This PSU is powering a Z97-WS with 4790K, GTX780, 7 hard drives, Areca RAID card, a H105 cooler, 4 case fans and 32GB of Corsair Dominator memory. No stability problems whatsoever. Another splendid Corsair power supply!

5 out of 5 eggsStill alive

This review is from: CORSAIR HX Series HX1050 1050W ATX12V / EPS12V SLI CrossFire 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: I give um a big number 5eggs. I bought two of these when they first came out and I have not had more carefree fun in all of my computing experiences. So I guess that makes them 3 years old or so.

Cons: Not really a con. More my own doing over the years they have some what merged together. As I was running together using a bridge much like a raid setup for hard drive with exact power supplies but with latest tech inside of these things and the tech in the bridge that merged them together. They are slightly warped and don't produce as strong a signal in the 24pin connections. Again my fault. But they work flawless for any power demand I might need.

Other Thoughts: I really did not think about all that three years ago with the duel setup. but it advantages out weighed everything. Being able to put power to the mainboard without regaurd or in a manner that was more tailored.
They were worth it to this day they work I owe alot of that to the idea that I SAW the sata cables and they were much different and I thought I should never mess with them....like changing them out for sleeved cables and whatnot. Was disappointed about the cables at first because of that. Soon I left the power supplies alone to do there job. And they did flawless over the years ran them through maybe 10 thunderstorms and they have always come out on top. Just a good power supply that will tandem with another one but does not favor going back to single after. And most of all A power supply that will never ever support the idea of changing cables. Even if the aftermarkets they sell in other places are for the 1200watt counterpart the cables need to say that famous 1050HX for me to trust so why mess with a good thing.

This review is from: CORSAIR HX Series HX1050 1050W ATX12V / EPS12V SLI CrossFire 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: It WAS good

Cons: until it started to make incredibly annoying sounds because of the gold coil... Disappointed.

Other Thoughts: Honestly didn't think I'd need warranty started doing this
2 months later, gonna buy a new power supply from a different brand although don't get me wrong corsair is great but power supplies might not be their thing.

1 out of 5 eggsThrice Dead

This review is from: CORSAIR HX Series HX1050 1050W ATX12V / EPS12V SLI CrossFire 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: My roommate has the exact same model, and it's worked for him....

Cons: I, on the other hand, have had 3 units die on me. One lasted about 1.5 years, the next 3 months, and the most recent, about 5 months, before the 12v rail started dropping too much and reset the computer. I've tried different outlets and battery back ups, makes no difference.

In addition, Corsair Customer Support is one of the worst I've ever witnessed. When you make an account on their portal, your address if permanently tied to your account. I can only hope that it can be changed by talking to their live chat, which naturally is only available during office hours. They also leave you to foot the shipping costs on an RMA when their product fails. Repeateadly.

Other Thoughts: Getting this model is apparently a gamble. Despite the overwhelming number of good reviews, I would never touch it nor anything by Corsair again if I could avoid it.

4 out of 5 eggsGreat PSU. Not quiet all the time.

This review is from: CORSAIR HX Series HX1050 1050W ATX12V / EPS12V SLI CrossFire 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready

Pros: I've been running the HX series of power supplies since I bought my first HX1000W in 2009. Since then, I've had one issue with the power supply where Corsair immediately sent me a replacement which ended up being the updated HX1050 model. Since then I've had one more (FREE) replacement (not due to any failure on the part of the power supply), and again received the most up to date model, this one featuring the "zero-RPM fan mode'. SEE CONS.

Overall great power supply, AMAZING warranty backed by a great company.

Cons: Zero RPM mode is completely silent at low-end loads, which is great. This works well for the RM450 I have in my server which is quiet and fan-less 100% of its uptime, I have never seen the fan turn on nor have I heard how loud it could be.

The HX1050, on the other hand, is LOUD. My newly built computer does not reach >30dB even under heavy graphical and CPU load thanks to my water cooling units. However, whenever the power supply decides it's hot, the fan revs WAY up, gets loud and fast for about 30 seconds, then spins down slowly and fades back to quiet.

This is pretty counter-intuitive. While it is nice that the fan will last much longer since it is not running for as much time (this would work inversely if the fan used sleeve bearings as the bearings would get sticky over time if not being used, but luckily these fans use dual-ball bearings). It would be MUCH nicer if the fan stayed at a low RPM all the time and never changed its speed. Then my computer would be quiet 100% of the time.

Wish I had just kept my 2013-model HX1050 instead of asking them for a replacement. That one ran quiet 100% of the time without this new "zero-RPM" mode stuff.

Other Thoughts: You don't need a 1050W power supply. Get out of here.

My system:
i7 4770k cooled w/ Corsair H110
GTX 770 cooled by Arctic Accelero Hybrid II-120
16GB DDR3 1600
120GB Intel 530
2 x 1TB Caviar Black RAID0
1 x 2TB Caviar Green

Full power draw under load: ~250W.

Yeah. Go get yourself an AX860 at most. A 650-750 will meet any single-GPU system's needs
