0पीएसयू लोगोपीएसयू क्षमता 2 – A typical gaming PC

Following on from the slight surprise that a new पीएसयू is a poor investment for a low power PC I decided I’d reassure myself that an efficient पीएसयू is a good investment for a typicalenthusiast” पीसी.


To do this depends on the configuration, how much time the PC spends on, and how much time it spends being heavily utilised. I’m basing this on a fairly-high power single-GPU system with a Core i7 सीपीयू and a Radeon 5870. I’m also going to assume the system is operated from 3pm – 11pm weekdays and 9am – 1am weekends, making for a total of 72 hours a week. I’ll also assume the system spends 50% time idle and 50% full-load.

The system in question pulls ~80w idle and ~340w under full load. Finding efficiencies for this is tricky, so the value will be rounded up to 400w (the पीएसयू’s in question don’t vary greatly between 300w and 400w)

All of these estimates are deliberately on the high side. I expect a typical PC will spend more time off, अधिक समय बेकार, और अभ्यस्त उदाहरण के रूप में तीव्रता के रूप में लोड किया. Most systems also use lower power सीपीयू’s and GPU’s too.

सामान्य के लिए आंकड़ा पीएसयू is based on the minimum requirement and is therefore a worst case. Even with a very poor efficiency पीएसयू डीसी ड्रा घटने के रूप में दीवार से एसी ड्रा में वृद्धि नहीं होगी. I have calculated a best-case yearly saving, 10p की एक किलोवाट घंटा चार्ज पर आधारित.

A new पीएसयू in this scenario is probably not advisable on a financial only basis. Even with quite a lot of heavy use, and comparing the most efficient पीएसयूएक बजट सबसे खराब के साथ ATX पीएसयू can perform the saving will take around 5 years to recoup. एक वास्तविक दुनिया उन्नयन इतना बचत शुद्ध करने की संभावना नहीं है.

If you are considering replacing an existing पीएसयू मेरी सलाह परेशान करने के लिए नहीं होगा, unless you have additional reasons. If you are buying new then it is worth paying more for a better पीएसयू, कारण के भीतर. Of course if you want the efficiency for other reasons (कम शोर, कम गर्मी) then those factors may make the value difference irrelevant.

अद्यतन (25-Dec-2011)

Huntkey जम्पर R90 जोड़ा गया. Whilst it is sold as a 300W पीएसयू, it does work slightly above spec, especially if well cooled. यह पीएसयू does make a bit of different to the conclusions. It produces savings of over £20, which is a significant proportion of the price of the पीएसयू! A payback period of 2 वर्ष, with an expectation that electricity prices will continue to rise would certainly be worth thinking about. हालांकि, the HuntKey isn’t specified high enough to really provide for the configuration specified in this scenario, and as such we couldn’t recommend running it beyond its rating.
