مجھے حال ہی میں ایک نیا مل گیا GPU میرے لئے HTPC which required a replace­ment power sup­ply as the old one was­n’t suit­able for power­ing a GPU ایک ساتھ 8 پن میں PCIe بجلی کی تار. The HTPC is in use for an aver­age of around 6 hours per day and with elec­tri­city at 15p/kWh any reduc­tion in power at the wall works out at 33p a year per Watt. This isn’t a big sav­ing, but if con­sump­tion is reduced by sev­er­al watts the sav­ing can add up.

Reg­u­lar “80 plus” (عرف 80 علاوہ سفید) اپکرموں are typ­ic­ally avail­able for around £30 with the cheapest 80 علاوہ سونے اپکرموں start­ing at £50. جبکہ سونے کے ساتھ درجہ بندی کرنے کا انتخاب PSU isn’t exclus­ively fin­an­cial, the poten­tial sav­ing is worth con­sid­er­ing. It is also worth con­sid­er­ing that a gold PSU that is less waste­ful will gen­er­ate less heat which will mean less fan noise is needed which is also import­ant in a HTPC. There are high­er rat­ings avail­able (Titani­um and Plat­in­um) but those products are pro­hib­it­ively expens­ive, and also don’t tend to be avail­able on lower power units. A typ­ic­al HTPC does­n’t need any­thing like 800W+ and as the 80 plus rat­ings only allow lower effi­ciency at the extremes of the oper­at­ing range an 80plus plat­in­um 800W unit at 100W draw may actu­ally be less effi­cient than a 400W gold unit.

Assum­ing an aver­age power con­sump­tion of around 120W and a 400W power sup­ply at 230V a gold rated unit would have to achieve at least 90% effi­ciency, where­as an 80plus white unit would have to achieve 82%. At these val­ues the white-rated unit will con­sume just over 146W at the wall, whilst the gold unit will con­sume just over 133W, a sav­ing of 13W, یا ہر سال £ 4. At this rate the gold-rated unit will pay for itself with­in 5 سال. اگر پی سی زیادہ کثرت سے استعمال ہوتا ہے تو یہ خود بھی تیزی سے ادائیگی کرے گا, یا پی سی مزید طاقت کھینچتا ہے, or if elec­tri­city prices go up. کوئی PSU with a 5 year war­ranty would appear to be a good invest­ment on fin­an­cial grounds alone, اور اس سے بھی زیادہ جب کم شور کو مدنظر رکھا جائے.

In terms of find­ing a reas­on­ably price gold-rated unit, in the past I bought a 300W “HuntKey Jump­er” but this is no longer avail­able. Sev­er­al retail­ers do have the Season­ic 350w GT تقریبا 50 ڈالر میں فروخت پر. Whilst the spe­cific­a­tions don’t men­tion it the pic­tures clearly show a 6+2 پن میں PCIe power con­nect­or as well as a 4+4 پن سی پی یو power con­nect­or which make it suit­able for all cur­rent hardware.
