Test: OCZ StealthXStream 2 500W

Konklusion

OCZ StealthXStream 2 serien er lavet til brug i små og mellemstore spillemaskiner. Der er to 12V linier på hver 18A i den testede 500W model, og den er 80+ certificeret, så den maks spilder 20% af energien som varme. I testen lå effektiviteten dog nærmere 87% hvilket jo kun taler til fordel for OCZ.


Innovation/Teknologi - 4
StealthXStream 2 serien har aktiv PFC, der giver en mere præcis DC spænding, og så overholder den til fulde den 80+ specifikation der er trykt på kassen. Det kan vi naturligvis kun bifalde, og derfor fortjener OCZ her et point over middel.

Udseendet er rimeligt konservativt. Den sorte farvegør StealthXStream attraktiv i en lang række designer kabinetter, hvor en kedelig grå OEM supply ville stikke for meget af. Det er nydeligt lavet, og kablerne er sleevede så de er nemme at holde styr på.

Ydelse - 4
Det er glædeligt at se en PSU i den billige mellemklasse, der rent faktisk overholder den ampere angivelse der er trykt på siden. Der var ingen problemer med at trække fuld strøm på alle linerne, og hverken støj eller ripple er i den grimme ende. Spændingerne holder sig også pænt inden for de tilladelige afvigelser hele vejen. Effektiviteten er rigtig fin mellem 100 og 400W hvor den ligger over 85%, så der er sagt god til en mellemklasse spillemaskine.

Pris - 3
DKR 450,- skal du slippe for 500W modellen, og dermed lægger OCZ sig lige midt i vrimlen af 500W PSU'er på markedet.

UK summary

The OCZ StealthXStream 2 series is made for use in small and mid-range gaming rigs. There are two 12V rails of 18A each in the 500W model we have reviewed here, and it is 80+ certified, meaning a maximum 20% power is dissipated as heat. I our test the efficiency was closer to 87%, witch is of course an added bonus.


Innovation/Technology - 4
The StealthXStream 2 serie feature active PFC for a more precise DC voltage output, and it lives up to the 80+ specifikation printed on the box. The technology is not the most advanced around, but it works well and we did not experience any flaws during our test.

Design/Layout - 3
It features a fairly conservative look. Tha black color makes it a candidate for many designer PC enclosures, where a dull grey OEM supply will not fit in. It is nicely done, and all the cables are sleeved so they do not mess up your build.

Performance - 4
It is good to see a PSU in the lower mid-end range that can keep up with the Amperage specifications printed on its side. We had no problems with drawing the full amount of Amps from any of the rails, and neither noise nor ripple is off the chart. The voltages are also stable within the ATX 2.2 specifications all the way. Efficiency is good between 100 and 400 Watts, where it stays above 85%. This makes it a good choice for a mid range gaming rig.

Price - 3
The pricetag is DKK 450,- (60€), witch puts it right along side most other 500W PSU's in this segment.
