Hey guys,i need suggestions regarding a PSU...the comp consumes about 420W...& the budget is about 2500...can stretch it to about 3000 if needed...could u guys please suggest a good one..which will work in future upgrades too??Thank you...
PSU needed with budget of about 2500
try the FSP Saga II 500W. its the only good unit under 3k. but with 420W power consumption? can you list the config please.
A
Gigabyte 80 Plus Active PFC 460W @ 2.2k
FSP Saga II 500 Watts @ 2.9k
VIP Gold 500W @ 2.2k
VIP Gold 600W @ 2.8k
Zebronics 550W Pro @ 2.8k
Zebronics 600W Pro @ 3.7k
found these around your budget.
the gigabyte 460 is a good buy but in your case it has very less headroom.
especially if you add a mid range graphic card.
if you ask me i find the zebronics 550w pro and VIP gold 600W sweet deals.
pick up one of them.
aah just read sam shab's post . there you have it so fsp is actually wrth the price , and at 100 rs more you wont have to flinch.
@sam.shab was my attempt ok?

buddy remove those bold marked PSUs. all those got too low 12V rail current. no way can any of them give anything near the marked output. & price wise they look even more ugly. FSP giving away 500W PSU with good 12V output (currently searching for the exact figure) & price is sweet. moreover its 80plus certified.
Confi is
P4 2.8 prescott
915GL motrherboard
250gb & 80 gb SATA

I think Corsair CX400 should be enough for this config.

Cooler Master Extreme 460 w @ 2600 .
Cooler Master Extreme 500 w @ 3200 .
All above will suit in your budget and requirement .

now thats a ridiculous suggestion.
a good 400W unit enough.
get FSP Saga II 400W or Gigabyte 460W. it'll be enough. get Corsair CX400W if you want that extra 3yrs warranty.

ok so where d we get info about 12v rail ampere listing of all psu. do you have a link to a resource page?
sry for the late reply(net was down)..ended up buying corsair vx450w for Rs3750 from lamington road
newegg have it but problem is it got only few PSU from FSP.
with tax? nice buy.
although you have bought the PSU, still I would like to know.
how did you come to know that your PC consumes 420W. This rig shouldn't consume much more than 300-350W. Even that I think I'm writing quite high.
An FSP Saga II 400W would have sufficed, but good that you bought VX450, you won't need to upgrade PSU in future if you change your gfx card to a mid range one.

it isn't high. its almost the current assumption. reason: P4 power hungry. 8600GT with electrolyte caps will suck lot of current. say close to 75W. that 915 board too with electrolyte caps (all the chemical dried already) will draw lots of power.
OK, I don't really have much idea of power consumption of different components, especially older generation ones. Can you please tell me more about it. Here is what I know
Athlon II X2 - 65W
Athlon II X4 - 95W
gfx cards - depends, generally below 100W for a low end cards
HDD - max 10W for each HDD
so how much do motherboard, RAM & DVD Drives consume?

graphics card without the connectors, usually below 70W (75W is the limit).
HDD ---> 5W green. 10W blue & blacks.
motherboard ---> all motherboards consume same. depends on caps, chokes, the chipset. so not much of a difference.
ram & DVD write ---> no idea.
for processor, it consumes 90W if pushed to limit (95W processor). 95W or more if OC'd.
here is a little tool that will allow you to check the power supply usage
eXtreme Power Supply Calculator
yes. these PSU calculators can be used but Cool Buddy asking for the individual components. so gave him a rough idea
few days back i bought corsair cx 400w from kolkata for Rs2900.....its really a beautiful PSU. hop it'll last longer....
By varying the components at eXtreme power supply calculator I figured this:
RAM - 4w
DVD Writer - 27w (really huge compared to my expectations)
A regular desktop Motherboard - 35w
All are approx, slight variations may be there
So if we take the efficiency of the PSU at 80%, a 500W PSU will easily be able to supply 400W continuous power, so one can use this
Processor - 95W
regular Mobo - 35W/high end mobo - 55W
HDDx1 - 10W
RAMx2 - 8W
DVD Writer - 30W
3 Fans - 5W
So we have around 200W headroom for adding a graphics card that means it will accommodate a HD5870. So basically we cannot use a HD5870 with Corsair VX450 whereas using a regular motherboard and HD5850 should be perfectly fine with the same PSU.

no. 80% efficiency means to give you 500W of power it'll suck in more power from the mains. but of total AC power drawn. 80% will be converted to DC. rest to heat.
a better way. 12V rail voltage X 230V..
oh! I had completely misunderstood the efficiency rating. I used to think it's the percentage of rated capacity the PSU can supply continuously.
That means if my PC is consuming 160W & assuming my frontech PSU is 60% efficient, I'm unnecessarily wasting around 100W which is being converted to heat. So if my PSU was 100% efficient, i could have saved around Rs. 4.5 in electricity costs for every 10 hours my computer is running!
But if this be so, then Corsair VX450 will be able to supply 450W of current & then it will suffice for even HD5870. Is it like that?

Efficiency = output/input : for anything.
Actually there was some link which was given here by one user which i used to calculate...frankly even i was surprised that this confi could consume 420W...& i wanted to make sure that in future the amount of power is sufficient so as to not change the power supply again...
Yeah i even i had this whole efficiency confusion...corsair vx450w had something like 80+ efficiency..what does it actually mean??i heard thos local brands have efficiency of 40% or so..what does it mean??Ps:-Thanks for the suggestion guys...frankly i almost bought the FSP Saga II 400W but in the end went for vx450w..hope it works well..yeah the price was inclusive of taxes...
