New CORSAIR or XFX???

post #1 of 27
Thread Starter 
I'm currently in the market for a new power supply specifically a 850W Power supply, so far I've narrowed it down to two due to size of my case and specs>

1. CORSAIR Enthusiast Series TX850 V2 850W
http://www.newegg.com/Product/Produc...82E16817207017

2. XFX PRO850W XXX
http://www.newegg.com/Product/Produc...82E16817207017

Both are new and are also 850W.

any help would make my decision a lot easier thanks.

My specs:
- core i7 2600k
- sapphire 6990
- five fan modded NZXT Apollo case
- two Western Digital VelociRaptor 450GB 10000 RPM 6.0Gb/s
- One HITACHI Deskstar 2TB
- Crucial Ballistix Tracer 4GB with blue leds
- ZALMAN CNPS11X

An 850W is overkill. AMD recommends a 750W power supply to power a system with one 6990 in it, so that means even a quality 650W to 700W would be enough.

So, you can spend less money here.

The XFX Pro 750/850 XXX Units are better than the Corsair TX*** v2 units.

The XFX Pro Core *** Units are the same as the Corsair TX*** v2 units.

thanks for reminding me, however I am still worried about possibly needing more power in the future especially when I'm running a lot of high powered 120mm shark fans in my case as well as overclocking my 6990 and my i7 K as well.

FYI-Nvidia and AMD "recommend" PSU wattages based on peak wattage not sustained. For example a quality PSU rated for 750W continuous could for short peaks probably pull 850W+ with little or no harm.

My XFX 750W Black Edition for example, if the wattage rating was assigned like Nvidia or ATI have in mind for their "recommendation" would be called a "900W" PSU.

Most folks buy way more PSU than they need. I did certainly.

There's a Pro and a Pro Core? Or do you mean the Black Edition M12D's?

XFX got rid of the "Black Edition" PSU's.

Now they are all Pro XXX and Pro Core units.

The Pro XXX units are M12D's without the ugly green.

thanks for the alternatives and btw would the xfx 850w be ok for a pair of 6990s in cross fire if I'd decided to do it?
