Gigabyte Intros PoweRock KX 320W Value PSU

btarunr · Jul 14, 2011

Gigabyte added a new entry-level model to its PoweRock KX line of value PSUs. The new one delivers 320W of continuous power. It bears the same feature-set as other models in the series, which include 370W, 420W and 470W models, with ATX 12V v2.0 compliance, OVP, OCP, UVP, and SCP. With a dual 12V rail design, PoweRock KX 320W is rated by Gigabyte to have efficiency of over 78%, and mean time before failure of 100,000 hours. Unlike many PSUs in the low-wattage segment, this PSU uses a 120 mm fan to cool it. Gigabyte didn't give out a price-tag.

So like most Gigabyte products it will fail shortly after the warranty expires?

320 watts? its really tight for today rigs

Continuous. I am wondering what the max value would be .....

320W and an "efficiency" of 78% ??? That's soooo 2005!

Ok, seriously: I really appreciate that a mayor vendor decides to market such a low-wattage PSU. Every time i build a value pc (120W TDP, 50W idle) , i struggle to find a PSU that isn't three or four times oversized. But the "78%" efficiency rating is just ridiculous. Every PSU should at least come with a "80+" sticker, even if it's value-oriented.
The 320W rating should be enough for plenty of PCs, taken that it is a real 320W PSU and not a re-stickered 250-odd one. A decent PC with, say, a quad-core and HD5770-class graphics will be perfectly happy with just 320 watts.

Who said it will be the same price as those? it's aimed at standard office dual/quad core pc's and I would have one of these over a crappy generic one that most office PC's come with.

Love these threads

ZOMG these are crap, I would never but s**t like this....

yet those people feel the need to troll I mean post. If you don't see what market this is aimed at just ask instead of making the same useless comments in the same kinds of threads over and over again.

Chances are I'd use it for a "big box store" style of office PC, would have been nice if they could have gotten it 80+ tho.
