OCZ GameXStream 850w ATX PSU



When talking about power supplies, the general rule of thumb is more power = more noise. This is because in order to combat the extra heat produced by higher wattage power supplies manufacturers need to install more powerful (and noisy) cooling solutions.

However, this rule has been totally disproved by the OCZ GameXStream, which managed to produce a full and stable 850w of power without the noise and heat associated with other high wattage units we've tested in the past. Add to this the fact that the OCZ GameXStream is no bigger than your average ATX power supply along with its excellent efficiency level of over 85% (as tested by our equipment) and it's hard to even consider using another power supply for your high-end future gaming PC.

In recognition of these excellent qualities I need to congratulate OCZ for being the first company in the history of Overclock3D to receive our "Best In Class" award. This award signifies that the OCZ GameXStream 850w PSU is considered by Overclock3D to be the best all-round power supply in the 600w - 900w classification.

The OCZ GameXStream 850w is currently available from Specialtech for the very reasonable price of £115.

• Rock stable voltages.
• Ultra-high efficiency.
• Very silent for an 850w PSU.
• Fully sleeved cables.
• 36 month warranty with fast support.
• Internal adjustable potentiometer.
• Standard ATX size (amazing for a unit with this much power).

• Nothing worth talking about. A first for any PSU here at OC3D!

All GameXStream PSU's are the same. Pure, ownage. Best bang for buck unit OUT there, despite ripple issues @ max load. Never the less, great review guys. Great PSU too.Quote
