Four-Way Power Supply Review Roundup

• HardOCP: Tagan BZ 1300W PSU:
  
  

  "The Tagan BZ 1300W is the Tagan’s second 1300 watt attempt to pass our gauntlet and its second failure. On some fronts the BZ 1300W represents solid improvements over the previous ITZ1300 (such as the DC Output Quality and efficiency) but on others it actually takes a step back (total DC Output capacity at 100v and internal build quality). It isn't like this unit is absolutely horrible as it did do well on all of the 120v testing and when it went it did so simply shutting down or latching off. However, the BZ 1300W's three failures result in a product that is certainly not award worthy and certainly not from our experience a value as $429.99 product. Had this unit been a much more economically priced unit perhaps some of these short comings could have been mitigated by price alone, but as it stands this unit is positioned as a premier product and in that field it isn't close to award worthy at this time."

• Hardware Secrets: BFG MX-550 Power Supply Review:
  
  

  "BFG MX-550 proved to be an excellent product if you stay inside its maximum labeled power.
  
  If you pull up to 80% (440 W) from it, it will deliver at least 84.5% efficiency. Working with it at up to 60% (330 W) from its labeled maximum capacity you will see efficiency between 86% and 88%, which is terrific. Pulling its full labeled power efficiency dropped to 81.6% – not as great as the other results but still above the 80% mark.
  
  Electrical noise level was very low, far below the maximum allowed, and the voltages were always within 3% from their nominal values."

• Hardware Secrets: MSI Turbostream 600 W Power Supply Review:
  
  

  "We were surprised with this power supply. With so many people saying bad things about the many previous incarnations of Solytech we were expecting a power supply with low efficiency and that couldn’t deliver its labeled power.
  
  This unit could deliver its labeled 600 W at 52º C, which is wonderful, plus we could pull up to 746 W from it, and it survived!
  
  But this isn’t a “perfect” power supply. Its main problem is the presence of only two SATA power plugs. If you have more than one hard disk drive you will need to use an adaptor to convert a standard peripheral power plug into a SATA power plug. If this bothers you, then you need to choose a different product."

• PC Perspective: OCZ ModXStream Pro 600W Power Supply Review‏:
  
  

  "The OCZ ModXStream Pro 600W tested out to be a good power supply. It produced good voltage regulation and delivers excellent efficiency. In addition, the ModXStream does its job very quietly, is 80Plus and NVIDIA SLI certified, and comes backed with OCZ’s PowerSwap warranty. On the down side, the DC outputs were not as clean (AC ripple) as we have come to expect from OCZ and PC Power & Cooling. And the 3-Year warranty goes along with the lower price point. "
