while neither is considered best in class, both platforms have been reviewed as solid by independent sites and the 600w version will power your set up with no issue. the CM does offer modular cabling if that is appealing to you.
Any other suggestions for a better PSU at that pricepoint ?
Also would i need a more powerful PSU to crossfire in the future ?
I have not seen a 7850 crossfire review yet, but based on seeing single 7850 power consumption figures in reviews and knowing a 7850 on full load is very unlikely to draw more than 100W, I would not expect a system with two 7850s to draw more than 400W, more realistically 350W.
The Sapphire HD 7850 OC only needs one 6pin PCIe connector, so even a 550W PSU with two PCIe connectors is going to be plenty.
PSUs in your price range which will support 7850 crossfire:
XFX Pro 550W Core Edition or the 650W version.
OCZ ZS Series 750W or the 650W version.
is the PSU in that combo better than the best suggested on this thread?
The Cooler Master Silent Pro Gold 600W is better than the Pro M 600W in that it uses a more modern independant regulation design, it is more efficient, has more connectors and has a 48A +12V rail vs 40A on the SPM600W.
However it has very high ripple and noise on the 12V and 5V rails on full load. It is still in spec, but personally it puts me off the SPG series.
The one in that offer is modular?
It is in fact modular. It isn't easy to tell from the wording of marketing material but it's definitely modular.
well i know for a fact isnt included as coolermaster dont make it in white.... cheeky ebuyer!
