0सही HTPC बिजली की आपूर्ति 2020?

मुझे हाल ही में एक नया मिला है GPU मेरे लिए HTPC which required a replace­ment power sup­ply as the old one was­n’t suit­able for power­ing a GPU एक साथ 8 पिन PCIe बिजली का केबल. 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” (उर्फ 80 साथ ही सफेद) सार्वजनिक क्षेत्र के उपक्रमों are typ­ic­ally avail­able for around £30 with the cheapest 80 प्लस सोना सार्वजनिक क्षेत्र के उपक्रमों start­ing at £50. जबकि सोने की रेटिंग के साथ जाने का विकल्प पीएसयू isn’t exclus­ively fin­an­cial, the poten­tial sav­ing is worth con­sid­er­ing. It is also worth con­sid­er­ing that a gold पीएसयू 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% effi-ciency, 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, या £ 4 प्रति वर्ष. At this rate the gold-rated unit will pay for itself with­in 5 साल. यदि पीसी का उपयोग अधिक बार किया जाता है तो यह स्वयं के लिए भी तेजी से भुगतान करेगा, या पीसी अधिक शक्ति खींचता है, or if elec­tri­city prices go up. कोई भी पीएसयू के साथ 5 year war­ranty would appear to be a good invest­ment on fin­an­cial grounds alone, और तब और भी जब कम शोर को ध्यान में रखा जाता है.

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 लगभग 50 पाउंड की बिक्री पर. Whilst the spe­cific­a­tions don’t men­tion it the pic­tures clearly show a 6+2 पिन PCIe power con­nect­or as well as a 4+4 पिन सीपीयू power con­nect­or which make it suit­able for all cur­rent hardware.
