Conclusion

The OCZ PowerStream 420 is without a doubt one of the highest quality PSU's I've ever placed in my system. Among the power supplies I currently own: Antec 400W, True Blue 480W, TTGI-USA 4-fan TT-550TS, 14CM-450TS, 14CM-350TS, PCPower&Cooling TurboCool 510 Deluxe, and Silencer 400W. I'm honoured to add the PowerStream to this list, and the unit is currently (pun intended) in my reference system.

Not only has the unit performed flawlessly, it has been powering 3x120mm Sunons, 3x80mm LED Case fans, SATA HDD, ATA HDD, TDK CD/RW, Cooler Master Musketeer, Chaintech C-Box, and a Sapphire X800Pro. To be honest I was sceptical about reviewing this PSU, as I'd just finished testing the TurboCool 510 Deluxe, which I personally consider to be the best PSU on the market today. I was, however; pleasantly surprised with the PowerStream's performance, build quality, and accoutrements. The LED voltage sensors not only ensure the end-user will keep their rails on spec, but reflects the confidence OCZ engineers have in their unit's capabilities.

In other words, giving the end-user the ability to adjust voltage rails, presupposes a parts spec capable of such tolerances. That PowerStream is intended for BTX makes this unit an investment in the future. Very highly recommended!


I'd like to thank Ryan at OCZ Technology for providing the sample.


Question/Comments: Forum thread


Update 1st June '04 - on BTX form factor
I was just reading you review, and noticed an error. You incorrectly labeled the 6-pin AUX connector as a BTX connector. It is neither required nor even specified anymore for the new ATX 2.3 standard that includes BTX. In fact, it has even been removed as of 2.3, unlike 2.03 which is what everyone is used to and uses right now.
www.formfactors.org has a lot of good info about the new BTX power supplies and ATX 2.3, and it's where I got my info from.
