psu buying advice

[aby geek]

hi friends,

i need your help and guidance to decide which smps to buy.

there are so many brands that iam confused wch brand to go for at what price point.

right now iam thinking of corsair vx 450.

but i would like to stick to a budget of 3k.

i may add a gpu later , minimum being gts 450 and max being 6850 and equivalents.

ill put the questions so its easy to answer.

1) sanest smps purchase for a 6850

2)sanest smps purchase for a 450 gts

3) maximum card a corsair vx450 can handle.


please include ques 3 in the psu you suggest as well.


thanx in advance

Can u mention ur whole rig?

If your budget is 3k then forget corsair. The cheapest corsair psu is cx400 priced at 2.7k
You should look for either gigabyte or fsp brand psu since they are cheaper and you can get a 500w psu for 3k or less.
Get an idea of what your computer needs in terms of power by calculating it at cooler master's official website.

1.) for 6850 u need a 450W or more
2.)GTS 450 can b run on a 400W PSU
3.)max VX450 can handle depends on ur rig for e.g if u hv more than 1 HDDs,optical drives,3-4case fans then not advisable to plug in a 6850..
IMO if u wanna use 6850 u should think of nothin less than a 450W(500W) PSU from a trusted n reputed brand.
Now for 450W PSUs within 3k - u can look into Gigabyte Superb 460W,FSP Saga II 500W.U can also look into Tagan.
Wait for wat others hv to say too!!

gigbyte 460w superb @2.2k
corsair cx 400w @2.8k

but do mention ur whole config

 

[aby geek]

hey thanks for your replies guys.

heres my config:

c2d e7500 2.93
asus g41 p5qpl-am
a data ddr2 800 2gb
seagate sata 250 hdd
and a samsung dvd writer

and my budget is flexible, but i dont want to be a spend thrift right now.
what is the maximum gpu cx 400w and cx 430w can handle?

please stick to corsair,seasonic,tagan. or any other brands you believe are as good as these.

also if you know what gpu will be best to add to the current rig,feel free to give your opinion.

and please give me useful links like power and eff calculators for psu.

 

[Jaskanwar Singh]

6850 will be perfect for you..get corsair vx450w.
actually cx430w has lower amps on 12v+ than cx400w.

[Gollum]

What? Really? So where does the extra 30w go?

 

[Jaskanwar Singh]

cx430w can deliver 430w at 30C temp only..its mentioned at the corsair site.

if you will go for 6850 to 6870 -

FSP Everest 500 @ 4.1k
FSP Epsilon 500 @ 4.1k
Seasonic S12II 520W @ 4k
Corsair VX450W @ 3.7k

if you will go for GTS450 to 5770 -

FSP Saga II 500W @ 2.1k
Corsair CX400W @ 2.7K

 

[Piyush]

which is better
epsilon/everest?

i thought epsilon is costlier than everest

 

[Jaskanwar Singh]

at smc international both at same price..but i am unable to find a comparison b/w two.

though both have around 85% efficiency

 

[Piyush]

must be a wrong info on their site
coz as far as i know
FSP epsilon 700W costs between 6.5k to 7k

now the question is whether it is bronze/silver/gold rated

 

[Jaskanwar Singh]

ya there are 2 700w mentioned one at 4 and other at 5k
both are bronze
FSP
FSP

 

[pegasus]

VX450(/VX550) if you afford it or grab a CX400 (2.5K-2.7K approx) while it's still available, if you want to stick to 3K max.

 

[aby geek]

thanks guys

the fabled psu guru the sorceror , said no FSP. then he got annoyed with my undecisiveness and locked his pm. i hope he drops in here. iam sorry sorceror, please return.


about the tagan 500 heard its 83% and is around 3k

well jasji if iam going to go over 4k i would seriously like a top brand over FSP.

what about seasonic? how good is it.

thnx in adv.

[ico]

Go for Seasonic. Most of the good Corsair PSUs have been Seasonic OEM.

 

[ssb1551]

I dun think FSP is tht bad!!Jus wait for others'(Cilus,Jas,Sam,ico n many more) opinion.
Hey Jas, will it b really bad if 1 opts for FSP?
