[H] Corsair HX1050 1050 Watt Power Supply Review

post #1 of 7
Thread Starter 
Quote:
Corsair is known in enthusiast circles as a premier supplier of high performance memory and has risen to become one of the most talked about power supply brands around. Corsair was able to establish such an amazing presence in such a short time through the use of quality OEM builders (Seasonic and CWT), rigorous standards, and excellent support. Since its entrance into the PSU field, it has established a number of lines of power supplies to address (and overlap) just about every market segment with its GS, CX, VX, TX, HX, and AX lines. Today, Corsair brings us the HX1050 (CMPSU-1050HX), a replacement for one of its old standby units from the HX line, the HX1000W. This new unit is once more produced in conjunction with CWT.

Channel Well Technology (CWT) was founded and began manufacturing power supplies in 1993. Since 1993 Channel Well Technology products have shown up under various guises including Antec, Xclio, 2theMax, CWT, Thermaltake, Xigmatek, and Corsair. While most familiar to our US users from when it used to provide OEM services for Antec, CWT is one of the more complete OEM manufacturers as it has a fairly high level of vertical integration providing transformers all the way up to its well designed SMPS.

At least almost 3 months. I was going to get one when I swapped to Sandy in September.

Better late than never, I guess.

Dated July 2
Another CWT single rail. JonnyGuru is a much better review. Why, you get the real story. No fanboi bla bla this is such a great product because its corsair.

Let me point out some things that come to light.

But I'll say this again, too: 87.5A 12V rails are too much for single rail topology in my not so humble opinion. You're talking about almost enough current there to arc weld with. Think the unit will shut down if a transistor on the video card flames out? It may. It may not. I've seen single 12V units far smaller than this smoke hard drives due to bad connectors. They just don't see a partial short as a reason to shut down because the protection circuitry is too de-tuned in order to allow the high current flow. Therefore, you have to be careful running a single 12V unit this big. Make sure all connectors are in good shape, plugged in firmly and properly, and that there are no chances of short circuits anywhere.

More its the ATX standards. IMHO They are too loose. They allow for 10% + or - swing in voltage regulation. Look at this.

The unit only has 79 of the rated 87 amps, but look at your 12v. Its been my experience @ 11.7v is the point of bsod, app hangs and the like. Trust me 3 things at my desk at all times. A watch with a second hand, and a digital vom, and a calculator.
OKie IMHO gives it a awesome fair assessment. Can you find a better PSU for the price IDK, maybe not? What are you going to use it for, and for how long? I've tried figuring my gaming machines to the watt, forget it. Its a bad idea why again, ATX standards are too loose!

I give +10/ 12volt amps on gaming, OC workhorse machine. Do you need all of this extra amperage. Maybe not for a dedicated folding machine?
Trust theses words OCN. " Your mileage may vary "
