One of the staples of Intel's upcoming Haswell (http://www.engadget.com/2013/01/07/intel-announces-4th-generation-core-processors-at-ces/?utm_source=Feed_Classic&utm_medium=feed&utm_campaign=Engadget) 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. VR-Zone 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 (http://www.engadget.com/2013/03/22/corsair-vengeance-k70/?utm_source=Feed_Classic&utm_medium=feed&utm_campaign=Engadget) Robert Pearce tells The Tech Report 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.
