Intel Haswell's idle states reportedly won't play well with some power supplies

<div dir="rtl" style="text-align: right;" trbidi="on"><div class="copy post-body" dir="ltr" itemprop="text" style="text-align: left;"> <div class="image-container" style="text-align: center;"><img alt="Intel Haswell's lowpower state reportedly won't play well with cheap power supplies" data-src-height="190" data-src-width="620" src="http://www.blogcdn.com/www.engadget.com/media/2013/05/intel-haswell-psu-demands.jpg" /></div>One of the staples of Intel's upcoming Haswell processor architecture is its support for lower-power idle states that can rival tablet chips in power consumption, even on the desktop. However, that may come with a big caveat for budget and custom-built PCs: certain power supplies might not cut it. <em>VR-Zone</em> claims that those idle states require as little as 0.05 amps of current, which could be too nuanced for older or cut-rate supplies that deliver power in bigger clumps. That might not be a problem for companies building complete PCs, but Corsair's Robert Pearce tells <em>The Tech Report</em> that it may lead to a lot of motherboard builders playing it safe by disabling those specific modes by default. Many of us, in turn, would either have to buy a fresh supply or toggle the power-saving options ourselves. We've reached out to Intel to verify the truth, but it may be wisest to make a cleaner break from the past with any near-term upgrades.<br /> </div></div>
