OCZ EliteXStream 800W (Page 2 of 4) | Reports

Like the Seasonic M12II 500W, the OCZ EliteXStream has a clean black matte finish -- nothing fancy, nothing overdone -- I like it. The OCZ EliteXStream 800W does not incorporate any decorative lighting LEDs either. At the back is an open honeycomb mesh design to maximize airflow and minimize air resistance internally, as trapped heat could be a problem. Therefore, it's done as heat needs to leave the power supply as easily and efficiently as possible, because the OCZ EliteXStream incorporates only one 120mm fan at the bottom and incorporates no other fans. Standard power supply on/off switch is located to the right of the vertically oriented male connector for power input. A red/orange/green LED used to indicate status of power is placed above the on/off switch. As with most new power supplies, the OCZ EliteXStream 800W has an automatic full range (100V-240V) AC line voltage selection, so the user does not have to worry about manually selecting input voltage.

Being used to large, high power PSUs, I found the OCZ EliteXStream to be fairly small, like the Seasonic M12II -- a quick measurement indicated that the EliteXStream is only 2cm longer than the standard 14cm, making its dimensions identical to the Seasonic M12II power supplies. It's hard to find a real quality power supply, especially with such power output, with these dimensions nowadays anyway.

Flipping the OCZ EliteXStream over and turning it around reveals the bottom mounted 120mm fan, and the cable lead-out at the back. The 120mm fan (We'll take a closer look at later, when we open the power supply up) resides behind an 8-ring fan grille, which is fairly standard for keeping fingers away from the fan while minimizing airflow resistance. The fan is located a bit to the back, rather than at the center of the power supply. There are four screws attaching the fan grille to the housing, as well as four screws holding the housing together. A circular warranty seal is placed over one of these screws, and if you open the power supply, you void the warranty.

The cable lead-out is done cleanly with two zip ties near the lead out to ensure the cables stay in a bundle. Each individual cable roughly two centimeters from there are also individually zip tied around the sleeving. I'm not sure why they did that, but what I'm sure of is that it wouldn't hurt haha.

The OCZ EliteXStream 800W accepts universal voltage input, as mentioned earlier. For DC output, the maximum combined output is up to 800W; as suggested by the model. A combined total of 180W can be sent along the +3.3V and +5V rail, but up to 92.4W (28A) for the 3.3V rail and 150W (30A) for the +5V rail individually. The OCZ EliteXStream 800W incorporates a single +12V rail to maximize power delivery efficiency and minimize overhead -- up to 744W (62A @ 12V) can be sent through that rail. With all three combined, the power supply maxes out at 800W DC output.

A sticker next to the power information label says that this PSU made in Taiwan.

Their cables are long and far reaching; this is especially important if you are planning to install your power supply in a case that sets it in the bottom rather than the top. There's no lack of connectors either -- the following can be found on the OCZ EliteXStream 800W:

- 1x ATX 24-pin
- 1x EPS 8-pin
- 8x SATA
- 8x Molex
- 1x FDD
- 4x PCIe 8-pin (6+2)

That's probably more connectors than you'll ever need haha -- most of us probably won't be using eight hard drives and four graphics cards anyway. My only complaint in this area is that, while the EPS 8-pin power connector can act like an ATX 4-pin connector if you just connect the right portion, I still prefer separate connectors or at least a 4+4 pin block.

Like the PC Power & Cooling Silencer series, all cables are sleeved up to the first connector on each cable -- meaning that, for the Molex and SATA dongles, a good portion of them will be left not sleeved. It would be very nice if the cables were fully sleeved.
