dexter napísal:asi sa opakujem ale chill 510A nezvladol 8800GTS ...

chill je chill, kazdy poriadny 500W to potiahne aj keby tam je pretaktovany Kentsfield

Xenon

Zvladne to aj Eurocase. Su aj taki, co si k 8800GTX kupia 500W Eurocase a su spokojni.

chill je chill, kazdy poriadny 500W to potiahne aj keby tam je pretaktovany Kentsfield

len aby...
rezerva je totiz dobra vec a podla mna je napr. pri OC CORE2 a OC NV88GTS, 500W zatazena tak akurat...
a podla toho XT papka viac ako GTX
proste len pre istotu by som nahodil 600W...plakat potom nad BSOD je neskoro

Xenon

Preco plakat? Ved resetnes PC a hor sa kupit novy zdroj. :lol:

znacky ako EC a LC lakaju ludi na wataz, ktoru nikdy nemozu dosiahnut. pritom ucinnost zamerne neuvadzaju a ak uvadzuju tak nepravdivu(alebo pravdivu len vo velmi uzkom spektre zatazenia)

dexter napísal:rezerva je totiz dobra vec a podla mna je napr. pri OC CORE2 a OC NV88GTS, 500W zatazena tak akurat...

odporucam precitat http://legionhardware.com/document.php?id=635

podla toho to ten chill mal zvladnut...som to uz cital...
problam je ze zdroj moze lahko zobrat zo cebou aj nieco ine...
jednoznacne by som to nepodcenoval...
jo inak na defaltu CPU aj GK islo vsetko v pohode...

aj ty mas 520W corsair...
podla toho linku by urcite stacilo nieco okolo 350W...

dexman

v tom je najvacsi problem ludi, ze uprednostia wataz pred kvalitou prevedenia. chill sa uz pomaly moze rovnat k EC, LC...

stale si myslim, ze poriadny 500W zdroj bohate staci k 2900XT s akymkolvek sucasnym procesorom.

EDIT: zdroj som kupoval prave koli tomu, aby v horizonte 2 rokoch potiahol QC a poriadnu grafu. ten zdroj mi vydrzi este dlhe roky ak sa nebudu vyraznejsie menit ATX specifikacie.

EDIT2: sorry uz som trochu OT ale spotreba sa tyka aj tejto temy
v majovom PC Revue riesili spotrebu roznych systemov

Pentium D950 @ 3,74GHZ
Asus P5LD2-VM
4 x 1024 MB Corsair DDR2-6400
X1950XTX 512 MB
2 x Raptor 150 GB 10 000 RPM
spotreba pri maximalnej zatazi 265 W, tahal to Seasonic SS-350ET

Taketo prehnane reci citam a pocuvam dost casto

Pre Quad Core2Duo a 2x8800GTX staci kvalitny 550W zdroj.

Metiu

kto videl posledny diel oc tv ,tak si isto pamata ,ako tam typkovia mali zapojeny intelacky quad-core s odhadujem nejakou 7600-kou a spotreba celeho systemu (pretaktovaneho na nejakych 6.4Ghz) sa pohybovala okolo 280W

Cize pokial by sme zili v idealnom svete a kazdy by pisal na komponenty REALNE udaje (seasonic k niektorym typom udava efektivitu okolo 90% .. kiez by to bola pravda) tak by tu masinu potiahol aj idealny 350W zdroj

+ 8800Gtx (okolo 200W dufam ze nedristam) = cca 550W (samozrejme pocitame s "trosku" pretaktovanym quad-core ,ktore moze mat o nejakych odhadujem 80W vyssiu spotrebu) .. co z toho vyplyva ?
Quad Core2Duo a 2x8800GTX ? Nehrozi .. odskusaj a posli pohladnicu z nemocnice

TDP G80@GeForce 8800GTX je 175W (ak sa nemylim), cize vacsiu spotrebu mat nebude - v realnej prevadzke je spotreba ovela nizsia (samozrejme myslim 3D)

podla vsetkeho bude mat ATi este velmi vela prace na novych ovladacoch pre R600 ... Stale maju velke rezervy vo vykone. Existuje uz aj verzia 8.38, ktora prinasa dost velky narast fps:

Veru slusny narast vykonu s novymi ovladacmi...

Inak co je to za test v DX10 v tej tabulke...? Lebo ATi ma v nich v provnani s 8800GTX takmer nulovy vykon...

Ryko

Vdaka... takze podla tohto testiku ma ATi absolutne nulovy vykon pri vykreslovani tienovania v DX10...? To je mierne povedane trosku zvlastne...
Ale asi je zbytocne sa nad tym zamyslat, stale nejde o potvrdene a oficialne testy...
