Was wondering if a 650W power supply would be enough be power a quad core cpu and an ati 5770? Would i need more or could i do with less?

Cheers
 
Should be about right assuming its a premium brand PSU.

You would only need something more powerfull to run multiple cards or lots of additional hardware - drives/cards etc.

I run an i7 920 & 5770 on this (http://www.overclockers.co.uk/showproduct.php?prodid=CA-031-OC&groupid=701&catid=123&subcat=) which is 600W I think I could probably run another 5770 off it also.

Read the full review here. http://enthusiast.hardocp.com/article/2008/11/12/ocz_700w_modxstream_pro_power_supply/4

You should read the reviews, this one is not recommended.

120v Load Testing Summary


Similar to our recent Xigmatek NRP-MC851 review the OCZ 700W ModXStream Pro failed our 120v load testing not just once but twice with two different units. Upon attempting full load on the second unit the unit ceased to function and would only emit a high pitched whine whenever plugged in. While the unit was running however, it did have slightly better voltage regulation than expected from a group regulated design and it posted decent efficiency numbers. The unit ranged from 81.40% to 83.25% efficient with a peak exhaust temperature of 52c. While the unit failed our load test, I can't say it is as much of shock as the CWT PSH failure was since this is the first time we have seen this platform. One other interesting point is the fact that both units we received carry a test report produced by PC Power & Cooling verifying the output of these units. Given that both verified units failed our testing we have to conclude that during the verification process for units that receive the test reports from PC Power & Cooling that they are not run at 45c ambient temperature. OCZ in fact informs us that it tests at 40c, 5c lower than our testing requires. Lastly, we can draw one further conclusion from this result, this platform is not an enthusiast or industrial class platform like PC Power & Cooling lines or even OCZ's own EliteXStream or ProXStream lines.

The Bottom Line


While we had high hopes for the OCZ 700W ModXStream Pro given OCZ's decent track record and the unusually low standards that other 700w units have set forth in our testing to date the OCZ 700W ModXStream Pro hardly lived up to its “Pro” moniker. The unit’s build quality was decent but the component selection was certainly questionable and in the end the unit was unable to complete our testing at full power. As such at $104.99 (after MIR) the OCZ 700W ModXStream Pro simply cannot be recommended, especially in light of the fact that its PC Power & Cooling stablemate, the Silencer 750 Quad, can be had for $104.99 (after MIR) and actually does perform well in our testing. In the end the OCZ 700W ModXStream Pro is just another in a long line of 700 watt victims in our testing regiment.
