Näyttää siltä, että nykyinen virtalähteeni sanoi itsensä viimein irti. Tarvitsisin varmaan pikaisesti uutta, että pöytäkone taas pyörisi. Saattoi toki olla, että kun yritin säätää uutta kovalevyä koneeseen, hääräsin jotain solmuun, mutta on tuosta välillä ennenkin virta katkeillut. Nyt se ei enää näyttäisi pääsevän käyttikseenkään asti.
Koska en virtajutuista tiedä juuri tuon taivaallista, osaisiko joku suositella uutta virtalähdettä, mikä riittäisi nykyisen kokoonpanoni tarpeisiin? Nykyinen virtalähde on siis jokin Macron MPT-351P ja siinä on input 230V~4A 50Hz, output 350W max. Koneessa muuten on neljässä paikassa ramit täynnä yhteensä 6Gt, kolme kovalevyä (uusi mukaan lukien) ja USBit täynnä sälää. Voi olla, että uusi virtalähde riittää joka tapauksessa, jos kyse on vain siitä, että nykyinen on mennyt mäsäksi. Jos kyse silti oli laitteiston virrankulutuskatosta, niin osaisikohan joku päätellä sitä nykyisestä kokoonpanostani?
Tarkemmin raudastani tietoa tässä (lshw, ei välttämättä täysin ajan tasainen sattuneesta syystä):
