Wouldn't risk it. cx400 is for 3.2k and comes with active pfc. Seeing what you planned for your rig- vx450 is a no brainer.

I would recommend to read the psu guide properly in that case, I am sure the question you asked is allready answered on the guide.

[comp@ddict]

I have a query.

Config is like this:
P2 X4 940 BE
Palit HD4870 1GB GDDR5

Now I'm in a fix between two PSUs:-
1. Corsair VX550W for Rs. 5,500 odd
2. Tagan Stone Rock TG600-U37 600W for Rs. 4,600 only

Now Corsair PSU's give 85% efficiency, but Tagan Stone Rock PSUs supposedly give a 83% efficiency. ANd it can handle power upto 700W and a GTX285 + Core i7 work flawlessly on it.

But it's low cost makes me a bit wary that is it really that good. And on the other hand, I really need to go for a cheaper one(a.k.a. TAGAN).

So which one should I opt for. Reply ASAP.

But on which operational temps? I wasnt able to find about the operational temps of the tagan TG600-U37. You still have antec 650w and cm real power 550 as a good alternate.

[comp@ddict]

Costs of both?

And they have 2x6 pin I guess.

I will be going for HRDCore OCing too so.

@ The Sorcerer ,
You rock man, very nice article. One more vote from me to make this thread sticky.
I recently bought a Corsair TX 750 for my next gpu gtx 260/275/280 with my own sense. Your article proved my decision was perfect.

If you planning to hardcore ocing- I am sure even should be knowing that single rail has an advantage over dual/multiple rails always.

[comp@ddict]

But which one gives single rail, I have no idea about that.

For me, Hrd Core is actually 4Ghz on air, not higher than that.

And I'm really on the budget so is there a go ahead for Tagan, it beats competition by Rs. 1000

[surinder]

I was almost done with Antec-EA 650 but guess what comp@ddict added all new dimension Tagan Stone Rock TG600-U37 600W.

Is it better from Antec-EA 650 or anything else around 5k ?

[The Sorcerer]

Following notes updated:

Note: Powersupply advice and "myths" shouldn't be over-exaggerated unless its a bad powersupply or if there is a better psu available for the same price. Do note there have been cases of burnt computers which have been very serious such as the link below:
http://timesofindia.indiatimes.com/Citi ... 357502.cms
Its important to have proper wiring, earthing, sockets, UPS, surge protector at the same time as well. More advance the technology gets, so must the source. Electricity is a double edge sword, respect it and you get respect. You play around with it and you will learn that electricity has a pretty electrifying sense of humour the hard way.

[shaunak]

I ball has come out with a new "Sprinter" series.

Its not too bad. (Not cheap either)

I inspected it at the store. Its construction is solid and feels heavy. I wouldnt mind using it in a meduim range desktop. Its definately better than a VIP solution IMHO.

Pricing:
Sprinter 500 - Rs.2575/-
Black Stallion 600 APFC - Rs.4750/-

All I know is that the Tagan 600W PSU can deliver a max of 700W and can handle a GTX285 and Core i7 with ease.

[surinder]

Antec-EA 650 advertised to deliver 650 watts continuous power yes of course with more then 80% efficiency all the way but I don't know about its ability of max output. Anybody have any idea about it?

[The Sorcerer]

I got it confirmed that t600-u37 is not as true as what people claim. Tagan also didnt reveal many detailed specs as well- operational temps is one of them. For 4.7k, why would anyone buy a zebronics or an iball .

[acewin]

didnt get where zebronics in 4.7K came in the discussion

about t600-u37, well I do not think that everything can be 100% accurate, but it surely gives regular 600W, can give power upto 700W well the corsair ones are also considered to do similar job, just that corsair does not advertises it like that.

And if Antec-EA 650 has continous power of 650W then it canhandle to give more than 700W also.

So none of these are any bad choice for hardcore OCing or any such.
I do not think VX550 max power would be more than 650W or so. So, a final logical thought would be money and VX550 is little more costly for the requirement. but it certainly gives allout more than 550W continous.
But then if you are spending as much as 5.5K odd why not go for modular PSU. like tagan BZ600

[The Sorcerer]

^^ zebby psu came into point @ post #40.
Edit: Whoops its iball . My bad. edited.


vx450 is actually a seasonic 500w which gives power upto 600w- 650w easily. vx550 will give 700-750w on maximum load easily with operational temps of 50 degrees celcius. Corsairs are always rated way too conservatively.

[acewin]

true

[comp@ddict]

vx450 is actually a seasonic 500w which gives power upto 600w- 650w easily

Very true, Corsair knew that their VX450W is very good and powerful too, but they decided to play it safe and thus the name.

Update: Antec EA430 is added on lower end psu.

There's nothing to play safe though. Why play safe with a psu which is capable of handling more? But the reason is because different companies have different "idealogy" of labelling. I guess its better to buy a psu with 400w on proven normal load against a psu with proven peak load.

Cheapest 600W APFC PSU.

====

Anyway,
I was talking bout the Sprinter series, which is marked at 2.5K, so I guess it will retail at 1.5K .

Its solidly constructed and cheap. Felt better than the VIP ones to me at the shop. Decent choice for a mediocore system.

For some reason the guy wouldnt let me measure the short ckt amperage

[The Sorcerer]

^^ No actually cheapest psu with active pfc (according to me) is corsair cx400 and antec EA430 and u37 is actually lesser than 80% and topower psu have a pretty bad list of manufactured OEMS in the present as well. That will obviously explain they arent any good reviews of this unit tested on a load tester.

[The Sorcerer]

Update: Point added under the faq question:
Why would an el cheapo rated 800w give only 390w? Where are the rest going to? How do I judge a power supply?

Oh yeah this is also another very important point that many so called technical sound leave. Many companies brand themselves as 80+. But that's not all true. You see when AC is converted to DC, no matter how good a cooling is there will be a level of heat. On top if it, ambience can also add up to temperature on the power supply as wek. Do note that if the powersupply gets hotter, efficiency is will drop tremendously. This is called operational temps. Many reputed brands are well known are veterans because of transparency of details. Some do not reveal the operational temp details. By today's standards the efficiency is calculated on operational temps of 40 degrees celcius~50 degrees celcius. If the operational temps are not mentioned, most likely its tested under operational temps of 25 degrees celcius, like in older generation power supply like the coolermaster 600w extreme series. It is therefore vital to check a series of reviews and see if all the details are mentioned- as there are reviews which is used as, in reality more effective form of advertisement. If the details are not mentioned, better off taking the alternate one which has all the details. Besides why would a company hide the details if a power supply is good- unless its bad in reality.

[j1n M@tt]

anyone know hw is new Zebronics Pro sreies...looking at the specs, they seem very promising...not like the old platinum series.

[The Sorcerer]

I heard the newer ones are actually HEC OEM. ADDA fans and much better quality than the previous generation of the pro series. I think these are with active pfc but it needs to be tested properly by a mod at TE forums . So its going to take a while to put on the list.

[j1n M@tt]

know abt their pricing??

[The Sorcerer]

PRO-500------2850/-
PRO-600-----3700/-
PRO-350-----1850/-
PRO-550------3200/-
PRO-E750----6900/-
PRO-M500----3500/-
PRO-M600----4400/-
PRO-M800----9000/-
But I am not sure if the naming of the old version of pro are as same as new version of pro psu. If you see the sticker of the new version of pro, there is no UL number mentioned on the psu so its more difficult to identify which one is new and which one is old. But if someone can confirm if the boxing of the old generation zebronics pro is different from new generation pro, that's the only way the end users can find the different from old to new.

[The Sorcerer]

Update: added Cooler Master Real Power Pro 460 (RS-460-ASAA-D3) for lower mid end category.

[j1n M@tt]

^^price?? btw heard this is an awesome PSU for mid range usage

[The Sorcerer]

Its approx 4k. The psu should have been cheaper though. Corsair vx450 will still be a better buy against this done mainly due to the price.
