5.0 out of 5 stars Real good PSU, but be careful with the size June 13 2009
By Kuk - Published on
I just build a new computer with antec1200/CP850 and the power supply fits like a glove, but be carefull its only design to fit 3 cases, its above the standard in height.

- Really stable voltages.
- Cheap compared to other modular 850w psu out there.
- Looks great on antec1200 (matching color with the inner case).
- Fully sleeved cables and are long enough to reach a 1200 setup.
- Modular
- Very quiet, its not dead silent, but the fan bearly spins for sure there are other component much louder than this PSU in you average computer.

- Size, its above standard, so might not fit you average case.

Overall if you have an Antec1200 case this probably is the best PSU you can get considering price/preformance. But be carefull if you have any other case you might look elsewhere.

5.0 out of 5 stars Great but very proprietary March 3 2010

Replacing a smaller power-supply I had in the case, I immediately noticed a quieter system and all-around better air-flow in my computer. The power-supply is partially modularized ( I say this because I was hoping more of the cables could be modularized out, such as the PCI-E power cables for the video cards). The built-in cables on the power-supply are extra long, perfect for use with the p183 which you can wrap the power cables behind the back of the motherboard (my old power-supply cables were too short to be fully routed around the back).

Because Antec is using a larger Power-Supply standard, it allows for more features and better specifications compared to the smaller power-supplies you may be used to. With that, comes a much cheaper power-supply but it does not skimp on the features and abilities. I recently built an computer using an Antec p183 case which is one case that supports the use of the CP-850 power supply. If you're going to be utilizing an Antec p183, p193 or 1200 case then I highly recommend using a CP-850 class power supply. It would be ignorant to use any other power-supply because the case is practically designed with the intentions of using this larger power-supply.

Bottom Line: Get this power-supply is you have a p183, p193 or 1200, otherwise you're going to have difficulty fitting this power-supply in your case in addition to its extra-long cables.

5.0 out of 5 stars Antec CP-850 psu Feb. 1 2010

This is a great psu for a handfull of Antec model cases (Antec Twelve Hundred, P183 and P193 ). Large fans and ample cable lengths provide excellent psu cooling and power cable routing options to create a clean, less cluttered system installation. This will NOT fit in most other cases.

4.0 out of 5 stars Fine so far, one high-pitched noise, low wattage May 27 2010
By Darin Bellisario - Published on

Installed in a P193 Case

- The +12v rails have been stable so far
- Relatively low noise, low T at idle
- cable length is nice
- Solid pricing, although the CP-850 is a better deal if you can do without the extra wattage.

- NOT A kW PSU, 840W on the +12v rails, to get to a kW you have to use each voltage equally. By Comparison, the Corsair TX solution (their lower-cost solution in fact, compared to their HX series) generally has a +12v rail within 20-40W of the rated value. The +12v rail is by far the most relevant power source, so calling it a kW PSU is a trick that really shouldn't fool anyone. I knew this buying it, but it's still something buyer's should be aware of.
- occasionally a whiney, high-pitched noise, unsure of source
- Would MUCH rather at single +12v rail, the FAQ on Antec's website pushes this as a more stable solution (4 rails), but what they mean is an easier-to-make-more-stable solution, the Corsair TX-series has perfectly stable single +12v rails, at similar price points, just check out reviews.

Overall I'm happy with it, but unless you need the extra 70W I see no reason to recommend it over the TX750.

5.0 out of 5 stars Good Power Supply July 21 2009
By astroboy - Published on
Verified Purchase
Solid power supply. Has really good performance to price ratio probably due to antec desire for people to adopt a new non-atx sized power supply. Runs very quiet and stays cool. Not a true modular power supply as there are several power lines connected to the box. As stated often, only fits 3 specific antec cases so do your research - amazed from another site the number of bad reviews due to "not fitting my case".
