OCZ has just released a new incarnation of their mainstream StealthXStream series, with models ranging from 400 W to 700 W. Today we are going to review the 600 W version and see how it differs from the original StealthXStream 600 W.

Like the original StealthXStream 600 W, the new StealthXStream 2 600 W is manufactured by FSP.

The StealthXStream 2 600 W is 5.5” (140 mm) deep, using a 120 mm ball-bearing fan manufactured by Yate Loon Electronics (model D12BH-12) on its bottom.

This unit features active PFC, of course.

The new StealthXStream 2 600 W doesn’t come with a modular cabling system. All cables have nylon sleeves, which come from inside the power supply. The cables included are the following:

• Main motherboard cable with a 20/24-pin connector, 18.1” (46 cm) long
• One cable with two ATX12V connectors that together form an EPS12V connector, 18.1” (46 cm) long
• One cable with one six/eight-pin connector and one six-pin connector for video cards, 17.3” (44 cm) to the first connector, 3.2” (8 cm) between connectors
• One cable with three SATA power connectors, 18.1” (46 cm) to the first connector, 8.7” (22 cm) between connectors
• One cable with three standard peripheral power connectors, 18.1” (46 cm) to the first connector, 7.9” (20 cm) between connectors
• One cable with two standard peripheral power connectors and one floppy disk drive power connector, 18.1” (46 cm) to the first connector, 7.9” (20 cm) between connectors

All wires are 18 AWG.

The cable configuration shows that this is a low-end product. The two video card connectors are installed on the same cable, instead of using separate cables, and there are only three SATA power connectors. Even though the distance between the SATA connectors is above the average (usually manufacturers use a distance of 5.9”/15 cm between connectors), you may find it hard to install your SATA optical drive and your SATA hard disk drive on the same cable. We think this product deserved at least two SATA cables with at least two SATA connectors each (three would be great).

This is almost the same configuration used by the original StealthXStream 600 W. The only difference between the two models is that the older model uses two six-pin connectors for video cards, instead of having one six/eight-pin connector and one six-pin connector.
