This article on পিএসইউ efficiency for a modern sandy bridge gaming PC follows on from 3 previous articles, সম্পর্কে পিএসইউ efficiency for a medium power server, একটি medium use very high power gaming PC এবং একটি low power server or HTPC.
In this article I’m going to assume the system is operated from 4pm — 10pm weekdays and 10am — 11pm weekends at full power. I’m also going to assume the system is on and idle for the rest of the time.
দ্য system in question pulls ~45w idle and ~247w under full load. I’m assuming an AMD Radeon HD 6870 (18w idle, 163w full) instead of the EN9400GT (11w idle, 23w full), the power numbers are adjusted accordingly. All of these estimates are deliberately on the high side. I expect a typical PC will spend more time off, more time idle, and wont be loaded as intensely as the example.
জেনেরিক জন্য চিত্রে পিএসইউ সর্বনিম্ন প্রয়োজনীয়তার উপর ভিত্তি করে এবং সেই কারণে একটি লক হয়. এমনকি একটি খুব দরিদ্র দক্ষতার সঙ্গে পিএসইউ যেমন ডিসি ড্র কমে প্রাচীর থেকে এসি ড্র বৃদ্ধি হবে না. আমি একটি সেরা-কেস বাত্সরিক সংরক্ষণ হিসাব আছে, based on a kWh charge of 10p.
Make / Model | Efficiency at idle (45ওয়াট) | Efficiency at load (247ওয়াট) | Est. খ্রি. আকার ক্ষমতা (অলস) | Est. খ্রি. আকার ক্ষমতা (বোঝা) | রক্ষা |

HuntKey Jumper R90 300W 80+ Gold | 88% (at 60W) | 89% (at 250w) | 51ওয়াট | 281ওয়াট | £32.59 |
The conclusion is no longer clear. The value of an upgrade has improved over the previous scenario with a gaming PC. However, even with a lot of heavy use, and comparing the most efficient পিএসইউ’s with the worst a budget এটিএক্স পিএসইউ can perform, a new পিএসইউ will still take around 4 years to pay for itself. A real world upgrade is unlikely to net this much saving.
If you are considering replacing an existing পিএসইউ my advice would be not to bother, unless you have additional reasons. If you are buying new then it is worth paying more for a better পিএসইউ, within reason. Of course if you want the efficiency for other reasons (low noise, low heat) then those factors may make the value difference irrelevant.

Corrected slight error for Modu87+ and added the HuntKey Jumper R90. This পিএসইউ changes the conclusion for anyone with a low efficiency পিএসইউ. It produces savings of over £30, which is approximately the price of the পিএসইউ! A payback period of 1 বছর, with an expectation that electricity prices will continue to rise is well worth the investment.
