OCZ ModstreamPro700Watt. Enough for this build?

[aleksanderdev]

Hi.
Was wondering if the OCS modstream 700 is a good quality PSU.
When it comes to PSU brands i know very little.
And is it enough to support this build

i7 3770K CPU
Corsair H100 watercooling.
Asus GTX680 (wanna upgrade to sli later.)
Z77 Sabertooth
16 gig memory
Storm Trooper with 8 fans.

It is not a very good PSU i am unsure if it will support your current build but not for SLI 680 plus 0C here what you should be looking at CORSAIR Enthusiast Series TX750 V2 750W ATX12V v2.31/ EPS12V v2.92 80 PLUS BRONZE Certified Active PFC High Performance Power Supply

The OCZ ModXStream Pro 700W definitely won't be able to support GTX 680 SLI.
This is because it does not have enough PCIe connectors (only two) and having the PCIe and peripheral (SATA and molex) cables connected to the same +12V rail; the second one rated for 25A (12*25=300W). Finally the combined maximum of it's 12V rails is only 552W, which even on a single +12V rail unit would be a bit too low.

A single GTX 680 is rated to draw 195W at maximum, obviously two 195W cards cannot be supported by a 12V rail that supports 300W at most.

A ~700W PSU with a more sensible +12V rail layout, like the ones mentioned above will be able to power a build with GTX 680 SLI.
