I'm building a new computer and I was looking for a peer review of the build I have so far. I appreciate your help. This computer will mainly be used for gaming such as running bf3 and I would like to keep the total cost around $1200.
Approximate Purchase Date: This week 1/8/2012
Preferred Website(s) for Parts: newegg.com
Parts Not Required: Mouse, keyboard, monitor, speakers
System Usage from Most to Least Important: Gaming, and a tiny bit of 3ds Max and VFX programs.
The PSU you selected is an excellent PSU but why pay $190 for a PSU when you can get a PSU for $115 that is specifically designed for that case, gets a 10.0 jonnyguru performance rating and runs cooler and queiter than anything else due to its CPX form factor. ?
The Antec CP-850 is a superlative power supply by almost any standard. Its electrical performance is up at the level of its more expensive brethren, the Signature 650 and 850, and Seasonic's flagship, the M12D-850: Voltage regulation is extremely tight for all the lines at all loads, and the ripple noise is amazingly low.
The noise performance is excellent, with the <400W performance matching or bettering virtually every PSU tested thus far. Above 500W load in our heat box, the noise level goes over 40 dBA@1m, or about the norm for PSUs rated this high. It has the virtue keeping itself extremely cool, however, cooler than any other PSU we've tested at such high loads.
A serious consideration is that in each of the three compatible Antec cases, the CP-850 mounts on the bottom, and the intake for the PSU is quite separate from the rest of the system. In the P193 and P183, the PSU is in an entirely separate thermal chamber, and in the model 1200 (Note the DF-85 is built on the 1200 chassis so the CP-850 fits in the DF-85], a direct path can be maintained to the directly opposite, wide-open front vent. This means that our extreme hot box test conditions never apply to the CP-850; in other words, SPCR's test environment is unrealistically hot for the CP-850. Our atypical spot check with a room ambient thermal test showed the CP-850 would reach only 24 dBA@1m at 700W load in a 27°C working environment. This is ridiculously quiet for such high power output.
The above is an obviously unfair advantage for the CP-850... but what of it? Antec has used an integrated systems approach for its CP-850 and its best cases, and if that approach is an advantage over all other case/PSU combinations, then, all the more power to Antec!
For the quiet-seeking computer gaming enthusiast, the CP-850 (along with any of the three compatible cases) is something of a godsend. Fantastically stable power, super low noise at any power load, long expected reliability due to excellent cooling, modular cabling, and all at a price that's no higher than many high end 6~700W models. That you're limited to one of three well-executed high cases from Antec — one mostly for silence (P183), one mostly for gaming (1200 [and its sibling the DF-85]) and one that's really an ultimate everyman case (P193) — is not exactly a hardship either.
Until Asrock offers an industry standard 3 year warranty, I can not recommend their products.
This GFX card is $40 cheaper and a bit faster than the 6950 .... however when ya add a 2nd one in SLI, it beats the CF'd 6950's by over 100 fps.
