I have 2 HD6950 2gb in a SLI
MSI 890FXA-GD70 MotherBoard
AMD Phenom II X6 1090 T 3.2 GHZ
16 GB Ram
Antec 1200 Case

I need help on finding what would be the best PSU for this system!
Please let me know what you think.

Antec 1200 watt psu and cooler master 1200 were suggested but I am not sure which would be best or if there is a better one out there. Should I only get an 850 Watt PSU?

If there is any other info you need just ask. Thank you all

Thanks for the suggestion I noticed that the Corsair is not Modular is there a Modular PSU that you think would work? Also, would I get any benefit from going with the 850 Corsair over the 750?

Hands down, the CP-850 .... it's specifically made just for that and 3 other cases ..... nothing in its price range even comes close.

It is completely unmatched by any ATX unit on the market I can think of. You'd have to spend twice as much as this thing costs to find the next best thing, performance wise.

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 [four] compatible Antec cases ... in the model 1200, 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! It's not uncommon for enthusiasts to frequently replace the motherboard and components that mount onto it — such as CPU, RAM and video card — while the case and PSU are retained. There would be ample reason to take that approach with the CP-850 and one of the compatible Antec cases.

For the quiet-seeking computer gaming enthusiast, the CP-850 (along with any of the [four] 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 one that's really an ultimate everyman case (P193) — is not exactly a hardship either.

The CP-850 is non-standard, but compelling, and in its typical application, as powerful and quiet a PSU as anyone will ever need.


And you don't want modular ... you want hybrid modular where all the "necessary" cables are hard wired. Only the "optional" cables should be modular.
