I am torn between SeaSonic X750 Gold 750W---------COUGAR SX850 COUGAR-SX850 850W


I have very recent experience with the 1000w version of the cougar (2 weeks ago) and i am absolutely pleased with its performance however...

This build is on a tighter budget and the 30$ difference is worth asking the question so here I am! The Seasonic is as you can see 750w and cert GOLD the cougar is 850W cert silver... the dilemma is lose 100w for the gold rating and also the 30$ savings or spend a bit more but get 100 watts more to have a bit more headroom but take a small hit with a silver rating?

specs for this rig are more then likely as follows

i7 2600k (mild oc)
8gb 1600 G. SKILL ram
THOR v2 case
More then likely 2x 6950's in crossfire *
digital fan controller
possibility for water cooling

Any and all input is greatly appreciated and personal use with a relatively demanding system using the seasonic 750 would be great

The Seasonic will keep easilly the crossfire. My advice gat the 850w because you overclocked the CPU and is better to have a little Watts +.

With the Seasonic 750W you can run 3-way HD 6950s in CF without any problem, the single HD 6950 draws about 160W (itself) in Full Load, 2 in CF will draw about 320W gives you a plenty of 400W available, if you'll OC each nail on your PC it would be more than enough.

Also, the Cougar is a great PSU and the model You picked is such a great one compared to other small market segment HEC's PSUs.

Overclocking a K will not add more than 25 watts to the total power consumption.

I vote the Seasonic! Just ordered one on Thanksgiving.

It got great reviews from Jonny Guru and Hard OCP.

One thing I'd note though, is that the seasonic is fully modular, whereas the cougar is not.
