The Antec VP450 delivers 450 Watts of reliable and continuous power, with dual +12V @18A output rails to ensure greater system stability.

it seems you are here to troll. If you run your psu at overload settings its gonna get fried faster than an egg cooking in 100 degree Celsius oil :D.

so stop posting bullshit about what you dont know, and eat cereal ;) which is to your right? or ri8?

I give up u r right...
Sorry & I may delete my post if u say so.

U yourself say dual rail is for stability & then disagree wid ur own statement.

Mind ur lang.. nobody is here 2 troll

Check temps on overload tests : they didn't cross 50C

All-in-all CX430v2 isn't good as it used 2 be cause more people are reporting cases of RMA..

the text is from newegg. you are trolling. point in case? overload test means when circuit starts tripping, the egg frying was a metaphoric example.

where are these rma cases coming from?

Overload protection[edit]

Power supplies often have protection from short circuit or overload that could damage the supply or cause a fire. Fuses and circuit breakers are two commonly used mechanisms for overload protection.[6]
A fuse contains a short piece of wire which melts if too much current flows. This effectively disconnects the power supply from its load, and the equipment stops working until the problem that caused the overload is identified and the fuse is replaced. Some power supplies use a very thin wire link soldered in place as a fuse. Fuses in power supply units may be replaceable by the end user, but fuses in consumer equipment may require tools to access and change.
A circuit breaker contains an element that heats, bends and triggers a spring which shuts the circuit down. Once the element cools, and the problem is identified the breaker can be reset and the power restored.
Some PSUs use a thermal cutout buried in the transformer rather than a fuse. The advantage is it allows greater current to be drawn for limited time than the unit can supply continuously. Some such cutouts are self resetting, some are single use only.

What is trip unit (circuit breaker)? - Definition from WhatIs.com

better stop eating cereal and start using the internet

we couldnt pull more, than shown in the table below, or the power supply would shut down. Indicating that all its circuit protections are working well.

stop derailing the thread with useless info and one line answers.

But the ANTEC one can deliver 432W of power to its dual Volt rail and I didn't get it why I have to consider 18A current which is coming from one of its one 12V Rail. GPU and other components can fetch power from both the rails simultaneously.

any decent gpu requires minimum 20amps on +12v rail.

look what you are posting, its not even 20A

who said that?
Underrated unit. Overload tests prove it. A company could even label it as a 500w unit.

There was a time when Corsair used to underrate their units as well. If CX430v2 was rated like the old VX450 was, CX430v2 will be called CX390v2 or something.

An HD 7950 system drawed power of 364W atmost so theoretically it can b used on a 450W system..

12V*20A=240W

AFAIK even HD7950 has tdp of 200w

lol check the rail power requirement for 7950 .. 25A

yes there are 450w psu from rosewill with 40+ on 12v rails those kind of psus cost 6k+ and not easily available here. You can definitely run that.

underrated agreed, but its only delivering 18amps on the rail. even a gtx 650 requires 20.

:facepalm:

40A*12V=480W

How d heck can it be a 450W PSU??

It's not delivering 18A. Labelled 18A but delivering more than it. Infact delivering (properly) more than what CX430v2 does before OCP kicks in.

GTX 650 Ti does not 'require 20A'. Infact less than it. That GPU hardly takes in 100w. ~85w would be my random guess. Divide by 12V, you get the actual A rating for only the card.

i did some googling and found out nice articles which i will like to share.

Single Rail vs. Multi Rail *Explained*
*forums.hardwaresecrets.com/multi-rail-single/3558
PSU "amps" Myth

quotes of authors of these articles -

Gabriel Torres said:
To make a long story short, "rails" are group of wires with an independent over current protection (OCP) circuit
Phaedrus2129 said:
Multiple rail: each trace is monitored separately, so if, say, one trace goes over 25A the power supply will shut down.

Single rail: all traces are monitored all together, so if the total current going through the +12V outputs goes over, say, 60A, the power supply will shut down. Alternatively, no OCP may be present at all on the +12V rail.
Phaedrus2129 said:
So final verdict? Single rail or multi rail? Well, with low-wattage units it doesn't matter. OCP on a single rail is useful up to about 40A or thereabouts, which is where most 550W power supplies fall. So with 550W and under power supplies, it's a moot point. However, with high wattage units, >45A on the +12V (650W and higher) picking a multi-rail unit will provide you with an extra layer of protection. It isn't essential, and it has no impact on the power supply's performance. However, it does provide an extra layer of safety in case you get a short circuit. And I would consider it a must for >1000W power supplies; [H] recently tested the single rail Corsair AX1200, but they had an accidental short circuit, and since the PSU's OCP is set for over 100A, the short overloaded and destroyed most of their testing equipment. So there is a danger with single rail units over 1000W.

-------------------------------------------------------------------------------------------------------------------------------------------------------------------


any decent gpu requires minimum 20amps on +12v rail.

the antec VP450P does not have only 18 amps on its 12v output. see this figure for example.
*wccftech.com/images/reviews/hardware/Power%20Supplies/Antec-450WPSU/4.JPG

total 12v1, 12v2 max load = 360w. this means 360/12 = 30 amps.
and u cant simply add 18+18 = 36 in case of multiple rail psu. u will need total power rating in this case.

so antec VP450P is absolutely fine psu. :)

-------------------------------------------------------------------------------------------------------------------------------------------------------------------

Phaedrus2129 said:
If the total +12V capacity is less than 80% of the power supply's total wattage rating then it should be considered to have a lower wattage than what it is labeled as. So you take the total +12V capacity and divide by 80% (0.80) and that's the "real" wattage with regards to modern systems. So if you have a 500W power supply with 350W on the +12V rail then it should be considered to be a 430W power supply, since 350/0.8 = 437.5 (feel free to round up or down a bit; try to stay within 10W).

Having a +12V current rating that makes up more than 80% of the PSU's wattage rating does not make it a higher wattage power supply. This is because the wattage will usually be limited by some other component (usually the primary side parts) than the rectifiers that produce +12V current

Well this is lot of discussion and I don't know what these ampere ratings on 12v or whatever you guys are arguing. My brother has agreed to pay me more(sorry about these budget fluctuations but it's complicated and believe me I'm getting headaches because of this purchase). I decided to go with seasonic s12II 520w and APC 1.1kva. I know it's more than what is needed right now but I will surely add a good GPU later on and I don't wanna get a new PSU at that time. So far I've purchased these things from MDcomputers
1. NZXT Gamma
2. FX 6300
3. Corsair Vengeance 4GB
4. Dell 20"
5. GT 630 DDR5
