Znacka zdroja

[Diablo1st]

Ak mas prachy ber dajaky lepsi, ale v poslednej dobe sa noname znacky ako Eurocase a Mercury polepsili. Nahovorim, ze su na tom ako enermaxe ale ak tahaju slabsiu zostavu, tak to zvladnu. Len nemozu ist na plny vykon.
Mne uz rok taha 350W Eurocase s 120mm fanom Sempron 2800+pretaktovany na 2,4GHz a 6600GT,300GB HDD, DVD-RW uplne bez problemov a zo zdroje ide uplne studeny vzduch, a s nestabilitou som tiez nemal problemy a aj napatia sa drzali v pohode.

. . ..Pamatam si na test kde sa testovali nejake vykonne zdroje a Q-tech 650W mal ucinnost oklo 35% pri plnej zatazi, mal tri fany aby sa to teplo stihalo odchladit, hucal jak svina, a teda pri plnom odbere spotreboval nieco okolo 1,3KW a to uz sa na ucte za elektrinu pekne prajavi. l

No, inac som nasiel ten test na webe, bo som nieco hladal o tom zdroji. Jeden typek ho predava v bazari, ale toto ma presvedcilo.

QTec's Triple Fan 650W is clearly a joke power supply. From the triplet of cooling fans that battle against each other to cool very little, to the supposed ratings that don't even add up to 650W, finishing with the massive failure for the PSU to get anywhere near its rated output. At 350W the outputs started to fluctuate rapidly before settling down.

By 450W, efficiency was dropping like a stone, input power increasing at a very rapid rate. At 50% efficiency and 900W of input power with the PSU making a horrible screeching sound, PD and I stood well back and recorded its demise on video. At 1100W of input power (1.1 kilowatts), it popped with a massive bang, the internal fuse letting go in impressive style.

For its rediculously low cost, the QTec Triple Fan 650W can only be described as a clown's supply. Buy at your own peril and don't say we didn't warn you. The worst supply on test by quite some margin and a complete misadvertisement of capabilities, suckering people into a poor purchase.

podla testou co som cital tak mi vychadzaju najlepsie asi tie Fortrony (500W = 2200sk + dan), ale som presveceny ze ak tam das EuroCase 550W bude to funfovat rovnako, akurat lacnejsie.

T.

tak s tymto absolutne nesuhlasim, toto je pekna blbost... vidno ze si este nikdy nemal znackovy zdroj...

moja skusenost s neznackovym nejakym shitom noname 300W po prechode z Ahtlon 800 , 256Ram , 15Gb HDD na Athlon 2500+ @ 3400+ , 512Ram , 160 S-ATA mi zacalo vypinat disk, preto som vymenil zdroj za Fortrona FPS350-THN (12cm vetrak) a plna spokojnost komp ide ako svajciarnske hodinky slovo ako RESET ani nepoznam vsetko na 100% spolahlive ziadne kolisanie napatia (s noname zdrojom mi to behalo bezne tak +- 0,2V)

takze tolko moja skusenost so znackovym a neznackovym zdrojom inak osobne ak staviam nejake PC s HW grafikou (nie integr.) vzdy kupujucemu odporucam minimalne Fortrona
