Leadtek 8800 GTS needs 550 W PSU ??? help needed!

[Dark_Placebo]

ive read the specs needed are 550 W and 26A on the 12v rail.... last time ive heard it only needs 400 W ?? but on the website it said 550 W,

and must of the ppl here told me to just get a 400 w psu.... am i misunderstanding something ? thanks alot !!

by the way... its LEADTEK 8800 GTS. thanks !

lemme clarify.... im understanding this bit by bit.... so... even if i have SLI 8800 gts with 4 x hard drives and 2 x dvd drives....

a 400W psu could handle all, as long as i have a high amp (30+ amps) on the 12 v rail ?

Well, no, because the total amperage depends on the total wattage. Like, your not going to find a 300w psu with 60a on the +12v rail, it's impossible. Read the PSU 101 & 102 sticky, it's all explained there.

 

[Dark_Placebo]

no.. that would just be for futture upgrades i really gotta study sticky...sniff

help needed !! this is the only PSU ive seen in my area:

cooler master real power... too bad i dont know how to read the specs..... but if im correct.... and add all amp on the 12v rail.... then it suffice... ryt ?

again... i would be using... (i have all available)

Intel E6600
Leadtek 8800 GTS
250 GB Seagate Barracuda (SATA)
Sony 18x DVD COmbo
2 GB Corsair Ram
P5B-E Plus

i would be adding in the future... a tuner card and stuffs...

would this be enough ? thanks alot !

 

[Dark_Placebo]

im gonna read it again now....

i live in the philippines....

my question now would be... in the worst case scenario.... being this would be my last resort.... or only PSU available.....

WILL THIS POWER up my system with no PROBLEMS ? thanks alot !

 

[Dark_Placebo]

wait.... if i computed that... the amps on the 12v rail is at 18amp... so.. 450 watts / 18 = 25 amps ? or am i missing something ?

 

[Dark_Placebo]

alright ! im getting this thing bit by bit!! but... how did u get the total V ? so... 264W dividided by ? which part ? if i divide 264 by 20.5.... it would be 12.8... where did u get the 12.8 ?

also.... after reading the psu..... i assume that the 12v is for the VIDEO CARD SOLELY ryt ?

 

[Dark_Placebo]

AAHHH !!! now i get it !! thats alryt dude !!

so i assume... that even with the 22amp still wont work ryt ?

by that.... and in the event i would use that... what consequence im up to ?? like.... my vid card wont work at all ?? or will some programs shut down after a while ??

about my question... the 12 v is for the Vid card ryt ??

and in the event the total wattage for the 12v is not indicated.... how will i compute for the total wattage ? thx alot !

 

[Dark_Placebo]

stupid me... i might have skipped that part...

okay... in the event i would find something.. lets say.. 500 watts... and 30 A on the combined 12 v rails..... but.... its not a recognized BRAND.. lets say..... Hec..... would that be better than buying a branded psu with lesser amps on the combined rails ? thanks alot !

 

[Dark_Placebo]

how about this one ? http://www.newegg.com/Product/Product.aspx?Item=N82E16817139002

 

[Dark_Placebo]

i do hope so the store has THAT !!! whew !!

by the way... how do you compute the total wattage on the 12v ? so that i can compute ?

and also my prev question.... if i find a non-branded psu with the complete specs..... would it be better than a low spec BRANDED psu ? thanks alot !!!!!!

 

[Dark_Placebo]

im so sorry for being so stubborn! my apologies...hahah !! i just called a local store... and they have this... unfortunately its not on new egg... its around $160:

http://www.shopping.com/xPF-Enermax-Enermax-600w-Noisetaker-Single-Dual-SLI-PCIe-PCI-Express-Ready-EG701AX-VE-SFMA-AX-2-0-Series-ATX

i cant compute the total amp.... cant find the total wattage on the 12v...

 

[Dark_Placebo]

ive researched a lil more... i found that the enermax one... has 27A on the 12v...

 

[Dark_Placebo]

wow... i never saw that.

worst case scenario if the corsair psu isnt available, would you advise to get that one since its already available ? but its $160..... sniff....

 

[Dark_Placebo]

Alright !! Now ive decided!! After reading your posts about the consequences of having a poor or low end psu could really be bad.... i wont sacrifice my system for that.

ill tell you tomorrow what the findings are! thanks ALOT for the help !!! w00t w00t !!!!!!!!!!!

 

[Dark_Placebo]

w00t w00t !! THANK GOD !! i was able to buy the Corsair 620 w psu !!! w00t w00t !! now im happy !!!

THANKS ALOT Mplichfamily !!!! if it werent for you... my good system would be for naught !
