I am planning to setup a i7 rig. I have a VX450 Corsair power supply

My config may be as follows
Processor : i7 920 Stock ( or even if overclocked will clock it till may be 3.4ghz)
motherboard: Gigabyte X58A-UD7 Rev 1.0
Hdd: 4 hdd ( all 500 gb drives )
Graphic card : 560 GTX or 560 Ti
Fans: 6 , all 120 mm
Lights: maybe 2 UV

and maybe a cooler like H50 or Cooler Master Hyper N520

So do you think VX 450 will handle the above config
If no , then please suggest a PSU for it, along with market rates.
 
Get corsair tx650 v2-6.2k or seasonic s12ii620w-4.6k,Vx450 won't be able to handle this much load it's safer to upgrade the psu,you can sell your vx450 in the market here on te if you are tight on budget.

you will be absolutely fine with vx 450 that is unless you start ocing like crazy....

and btw gatekeeper you know right that he can run 2 gtx 560 ti's with that setup on a 650 watt psu....

so my advice if you plan on adding a gfx card later to sli or plan to oc rigorously then take tx 650 or gs 600 a cheaper but solid alternative(don't listen to what people say about this unit i have personally used it with i7 870 and 2 gtx 460s of course not much oc and it held up like a champ)....

gs 600 corsair price in bangalore is 3.7-3.8k max.....

and if you don't plan on ocing or adding another gfx card to sli then you will be absolutely fine with your vx 450.....
 
see rahulyo's sig rig....x6 with hd5850 on vx450...x6 eats more power than i7 and his is oced :D

and on a secondary note..i would like to add instead of i7 920 make an i5 2500k rig...will be cheaper less power hungry more powerfull in gaming and general not heavily multithreaded tasks , hence vx will still do gud keep the gpu and other parts same(change mobo to sandy compatible like z68 chipset or p67 chipset) :)

hey thanks a lot for your suggestions, I will be taking the combo mostly from a friend. So just wanted to know how good the psu would hold.

I may go for a PSU upgrade if I am able to get a good one.
 
Take a Corsair TX 650W v2 ~ a better option than VX450.

Assume , VX450 is Tata Nano and TX650v2 as Maruti Swift

Swift will cruise more easily on 80Kmph while Nano will struggle to keep that speed.

IMO- Its the same case with PSU too, a higher wattage PSU will handle loads more easily than running low wattage PSU at its limits.

wrong bro...

if a system eats up 400 watts then let it be a 450 watt psu or an 800 watt one both will work the same and in fact the 450 wattge psu will provide a bit higher efficiency as it would have being fully utilized...

and btw...if ur aim is to drive at 40 km/h then why the hell would u take swift.....it would be a waste of power..got it...this is the right analogy....

now let me tell u what to look out for in a psu...

1) capacitor ageing...as all components capacitors in the psus age too...and the more aged they become the less current they can hold and in this the lesser the efficiency and wattage figure becomes...the difference won't be substancial for say 3 yar old psu but for a 6 year old one u could say there would be some wattage drop.....

2) 80+ efficiency figures does not mean it will provide better current or 80% of rated power....

80+ efficiency is a certification which means a particular psu can take 100 watt ac current from socket and can convert atleast 80 watts of it into dc form and provide it to the components in pc...hence efffectively reducing electricity bills...

3)now myth abt eficiencies....most psus r most efficient at 20-50 and 90-100 % loads..and they r not equally efficient under varying load conditions so maybe under some circumstances even a 80+ certified psu might work under efficient...

4) most people go on and on that u need tx series u need hx and blah blah..i say most of those people dont know how a psu works or what to look out for...they just follow in the footsteps of some other high reputed member who said tx 650 awesome and hence they too start saying it without knowing actually why some guy suggested that unit and what benefits it holds...

now about tx and gs series....

tx

---

costly---does matter most

better build quality---does it really matter that much its not as if u r gonna shake it and drop it on everyday basis :P

has all japanese capacitors---results in longer life and better efficiencies...

higher working temperature of 50-60c---again does this matter too much..u aren't going to keep ur case in an oven do u :P

gs series

---------

less cost---matter most

good build quality---but not on par with tx series...but much much better than any psu like local ones zebby platinum series cm gx series corsair cx series etc etc...so again does not matter much...

mix of japanese and taiwanese capacitors---again does not matter high quality taiwanese caps and some high quality jap caps are not a bad deal..in fact its a bargain at the price point its selling...

lastly its operating temperature of 40-50c---again u r not going to put ur pc in oven so don't worry unless u r running high end stuff in some crappy zero airflow case..even then psu's don't reach 50c easily unless heavily stressed to their limits...

hope i cleared some misconceptions and the monotony u guys have...... :)

there are many more points like
ripple effects
atx spec compliance
voltage rails etc etc....but i dont have the patience right now to edplain those..xams on gotta sleep :)

All the stuff you wrote is very nice and all, but if he plans to overclock, its better to leave some additional headroom for the power. Plus he might even overclock the GPU. Thats because overclocking is usually infectious, people try to do all sorts of crap, and when the shit hits the fan, they sit with their hands on their head :rofl:

actually the point was why take the tx when gs is available for cheap and performs like a champ with negligible ripple or efficiency problems....

bcoz if we go by some other people's logic(not u ) then there argument will be tx better than gs ok i agree..then i will also say why not take hx or even better ax.....

so u see this was my point...... :)
 
@deaddevil :- Hey bro take TX650 v 2 or GS600 both r gud . If u have high budget thn go with TX series else GS series .
 
GS600 is rated at 40deg.c and TX650 v2 is rated at 50deg c and will be a better choice for the rig you have mentioned above.

PS: I am using GS600

I tried to explain in simple steps why TX is preferred over GS series. From your post, it looks like you always want to run your devices at 90% stress.. :tongue:

TX 650 v2 is a solid performer with better Ripple , efficiency, Japanese capacitors, good efficiency at all loads which makes it a better buy than GS .

If OP has strict budget, he can switch to GS series, there's no need to write an essay about it.

P.S: I've read a lot about PSU, so I've my own facts and experience about this.
 
Thanks a lot guys for your inputs.

i'll have to check on my budget, cause a TX is a bit costly. do you think people may offload their TX at this time, if I put a WTB thread in the market ?

how is a seasonic ?

u mean to say when people are wrong we should not shed the light on things and leave it at that...ur analogy was basically flawed and i think u belong to those psu overkill clubs where they teach u any psu other than tx is bad and not worthwhile unless u r on low budget....

and btw u again provided wrong info most all psu's r never completely efficient across the whole spectrum and tx is no difference in that fact from gs.

and u say ripple is better....u should only worry abt ripple in a psu when it goes down a certain threshold after which it can potencially cause damage to components...so unless ur psu is that bad u should not worry abt ripple and even the gx series from coolermaster which really have bad ripple to be called a gamer psu does not have enough ripple to cause any kind of component damage and gs series is leagues ahead....

have seen many guys like u ...doesn't matter to me what the op takes but for him i will say he won't notice even a 1% performance difference between gs600/700 and tx 650...so now its upto op whether he wants to save some money or just follow in with u guys blindly.....

and chiragsthakur...u seem like a kid from ur comments and that like u gave seriously....if u own a gs series it does not mean u can critisize it without facts.....

its as telling i have phenom x4 955 but i prefer and recommend i5 750/760.....got my point...this just shows how little u think before posting....

adios amigos..im off this thread..can't make people like u understand who have set mind set..... best of luck to op :)

seasonic is awesome as a psu company...
