Just bought a Enermax 550watt

[Sniper82]

Its only 20pin and am curious would it work with NF4 boards? Do I need to buy the 20-24 pin adapter? Its got 24amps on the 12+ rail is that plenty?

 

[hundesau]

everything about 20amps is fine, and: no, u dont really need the adapter, the missing 4 pins are only for further stabilization, they are redundant, so u wont even recognize if u dont have them. furthermore enermax is a good brand but i doubt 550Watt are necessary, id buy something like a 420Watt maximum power supply. dont think u need more not even with SLI@2 cards. the thing is that usually power supplies tend to have a lower kinf of input-output...hm, how do i explain it.....usually the relation of input of power to output of power is at its maximum at about 60% of usage. if u have 550watt u wont ever reach the 60% point. u will stay most of the time at lets say the 40% point. but the input-output relation at 40% usage is alot lower, so ur wasting input power. if u had a 350 or 420watt supply u would have a usage of 60% and the power correlation was at its best again. okay, i know u dont understand me right now....maybe someone else can explain it more simple. fact is, u dont need that much of watt instead it will in long terms cost u some more money for power due to that bad input-outpu relation that a supply of high watts has when not used with highly demanding components. not that much of a big problem but ya know...makes no sense to have a 550watt power supply in my oppinion, but its ok though.

actually some of the Nf4 boards do need the 24pin. DFI told me it will require it and not to use a adapter

 

[hundesau]

whats the difference between adapter and a 24 pin right from the pwer supply? i doubt there is one. not sure though.

Hope thats not true because I was hopeing to get a DFI NF4 board once its here. I got the PSU for $45 shipped. If I was buying new I would have went with a 450-480watt. I won't buy another PSU just to use a DFI. I will just have to go with a different brand.

Either way the DFI will probably be out of my price range anyway.

 

[Justin343563611]

Yeah I have a 550 watt PSU 20 Pinner. Will an adaptor work for me?

 

[Demo24]

yeah im gonna have to buy a new PSU also for the DFI. I dont see why they wouldnt tell me it would work with a adapter if it did. Means more sales for them. But I have heard people say on this board theres problems wiht useing adapters if mobo requires 24pin

 

[hundesau]

i dont see the reason for problems. if u buy a new psu then u gonna have an adapter also. there is no difference between an adapter and a native 24pin connector.

Enermax Noisetakers have the 24 pin connection. Also, my EG425P-VE model is 420 watts but has 29A on 12v rail.

Actually it could make a difference if you need more current. i.e. Four 12G wires will carry twice the current of two 12G wires.

 

[Sniper82]

So is it a bad idea to use the 20 to 24 pin adapter? Or is it a mystery as to whether it will hurt the PSU or whatever in the long run?

 

[Blazer]

Never use a 20 pin psu plug to a 24 pin mobo connector,adapter or not.
you can use a 24 pin psu connector with a 24/20 pin adapter to a 20 pin mobo connector.

The MOST important part than you cannot skimp on is the PSU,WHY anyone would spend $1000.00 or more on sys componets and only buy a $50.00 or LESS PSU is beyond me.

why is it the Gigabyte GA-K8NXP-9 reviews and stuff lists it to work with both 20 and 24 pin?

 

[hundesau]

erm, blazer? thats.......not rite.

first: the only reason the extra 4 pins exist is to stabilize the slightly higher power needs of pcie bus architecture. but i know a couple uf guys who didnt buy a new psu for there boards and use the 20pins connector and nothing bad ever happened to them. so if ur scared buy an adapter, but dont buy a new car just cuz ur running outa fuel.
second: the reason to buy a 60$ psu is that u dont need to spend more then 100$ to get a good quality psu. take a tagan for example or bequiet blackline series or a somehow louder enermax. they dont cost more than 70$ and will give excellent results.

 

[hundesau]

@sniper: cuz both the psu u got and the board u have do have the same ATX specs. See ATX is an standard and a every ATX thing may it be a board or a psu has to fulfill certain requirements and one of these is that it must work with all ATX specified components. Its a standard, a norm. So every ATX standard psu will/must work together with an ATX standardized mainboard. Esay as that. The new psu standard is called ATX12V v2.0. Still it is ATX and will work with every ATX mainboard. But it has instead of the old 20pins connector a 24 pin connector and some other minor changes like s-ata connectors and they took away the 6 Pin Aux connector and some other minor stuff. And sitll the old ATX standard has to work with the newer one. Those are the fucklng rules with standards .

 

[Sniper82]

anyone using a 20pin PSU on a NF4 board or NF4 Sli?

 

[Demo24]

the giga-byte doesnt need a adapter. others require the 24pin. Im not lieing why would I? Ask them for yourself and see what they say

I been using an antec 550 with 2x 6600gt on an Asus A8N-SLI for a couple of weeks with no issuses.


from the Asus news room: Unlike the SLI solutions by other manufacturers, the EZ Plug supports the 20-pin standard, which is still currently the mainstream. Users who want to upgrade to the latest SLI platform, can save the extra cost on a 24-pin power plug. In addition, a LED light issues friendly reminders when the EZ Plug is needed to ensure the graphics cards can run at full power without compromising system reliability.

That sounds awsome but I don't want Sli and I think thats the only NF4 board Asus offers ATM? Whens there Ultra due?

That the only mobo brand with that?
