Final Thoughts and Conclusions
The new ProXStream 1,000W joins the GameXStream 700W power supply as being two of the best power supplies OCZ has brought to market. The ProXStream 1,000W PSU delivers a lot of stable power in a very compact enclosure. The DC outputs were solid and the +12V rails were very strong. The overall efficiency was good and the 80mm cooling fan did an excellent job of keeping all the internal bits cool, at the expense of being noisy. In addition to the sleeved cables, the black-chrome finish looks awesome. For the majority of power users and/or gamers who are looking for a compact, high output power supply, and who are not too worried about noise, the OCZ ProXStream 1kW PSU should be an excellent choice.
Initially I was concerned that the ProXStream PSU might have a problem delivering enough power to support overclocked 8800 video cards (based on OCZ’s 20A maximum +12V rail specification). However, testing showed that both the +12V3 and +12V4 outputs are capable of delivering well over 300 watts each, which should be enough power for a pair of overclocked 8800s.
The OCZ ProXStream 1,000W power supply has a typical street price of around $300 USD and is currently available from Newegg.com ($299.99).
Strengths:
- Up to 1,000 watts DC output
- Solid, stable voltages
- Excellent build quality and high efficiency
- Compact enclosure — only 140mm deep
- Active PFC and Universal AC input
- Up to 70A on the +12V outputs
- Four PCI-e connectors to support multiple video cards
- Black-chrome finish and sleeved cables look great
- Backed by a 3-year warranty
Weaknesses:
- Quite noisy
- No On-Off switch
For excellent performance and a lot of power packed in a small enclosure, the OCZ ProXStream 1,000W power supply earns Gold.
