Corsair TX 650 V2 or CX 750?

post #1 of 2
Thread Starter 
I can grab them both for £70. Will be powering an i5 2500k and a HD 6950 (might crossfire later).
Thanks!

The TX650 V2 is the superior unit and it would be overkill even if you added a 2nd 6950.  All that would really be needed is a quality-made 550W unit:

 

http://www.guru3d.com/articles_pages/radeon_hd_6950_crossfirex_review,14.html

 

With two 6950s under full load in their system, their PSU pulled 473W from the wall outlet.  Their CPU was idling, so I'll add 150W for an overclocked 2500K.  So a simultaneous full load between the 6950s and the 2500K would make the PSU pull 623W from the wall outlet.  If the PSU is 85% efficient while pulling 623W from the wall outlet, then that would mean the system is pulling about 530W from the PSU.

 

Here is a very high-quality modular PSU that would be more than enough for this:

 

The 550W SeaSonic G Series at Scan.co.uk for £73.86 inc. VAT

 

It can continuously deliver 550W "24/7" if it's ever needed.  ;)
