This is the third installment in a series of articles addressing পিএসইউ efficiency. Article one focused on a [intlink id=“76” type=“post”]তাত্ত্বিক নতুন সার্ভারে[/intlink], শিল্প-icle 2 একটি উপর [intlink id=“77” type=“post”]টিপিক্যাল ডেস্কটপ পিসি[/intlink]. This article will focus on a current real server, and introduces a new পিএসইউ — an 80+ platinum model.
The system spends a lot of time semi-idling (serving network and disk requests but not doing too much CPU-র কাজ). I estimated that it would pull around 150W on average, and then calculated it below. It really did come out exactly like that!
Base system Sempron LE-1100 (1.9গিগাহার্জ সিঙ্গেল কোর) nForce 630i উপর / 7050 motherboard. 2Gb DDR-II | 35ওয়াট |

অনাগ্রহ, assuming a cost of £0.10 per kWh this system would cost a total of £131.50 a year to run even with a perfectly efficient পিএসইউ!

জেনেরিক জন্য চিত্রে পিএসইউ is based on the minimum requirement and is therefore a worst case. I have calculated a best-case yearly saving, based on a kWh charge of 10p and assuming 24.7 usage.

উপসংহার: This is the first scenario where new higher-efficiency PSUs are reasonably price competitive based only on power usage. For such a system, a high efficiency পিএসইউ will pay for itself within approximately 3 years. If you plan to keep the system for more than 3 years a high efficiency পিএসইউ is a worthwhile investment as its TCO will be lower. As energy prices continue to rise this TCO advantage will widen.

Added the HuntKey Jumper R90. This পিএসইউ changes the conclusion conclusively. It produces savings of over £40, যার অন্তত দাম পিএসইউ! A payback period of 1 বছর, with an expectation that electricity prices will continue to rise is well worth the investment.
