400W psu problem

[lakshitharxx]

Hello.. I am currently using a Cooler Master 400W PSU.. Here is my rig..

Core i5 2400 3.1Ghz
Asus P8H61-MLX mobo
GTX 550 ti
4GB Kingston DDR3 x 2
1 Hard Disk
1 DVD Writer
120mm Cooler Master LED fans x2
120mm Cooler Master regular fan x 1
( NO pci cards, Not overclocked )

My rig is currently running fine without any problem..

I have two questions

1. Is my psu sufficient to add one more 120mm LED fan and one SSD?
2. If it is not can i at least add one 120mm LED fan?

I used extreme power supply calculator and it says

Minimum PSU wattage - 277W
Recommended PSU wattage - 327W ( With out fan and SSD i am going to buy )

Minimum PSU wattage - 283W
Recommended PSU wattage - 333W ( With fan and SSD )

With that setup I recommend using 600W or more. Calculators can be really of Both low and High. But 4GB ram that CPU and a massive GPU like that needs alot of wattage.

 

[lakshitharxx]

Ram is 8GB ( 4GB x 2 ) and PSU is enough for this specifications.. I want to know that can this PSU handle LED fan and a SSD?

 

[FinneousPJ]

Yes, it can.

 

[lakshitharxx]

Yes, it can.

Both SSD and LED fan? I am going to buy a fan on tomorrow and SSD in next week.. So isn't there anything to worry about?

No, nothing to worry about. An SSD and an LED fan are minimal additional power. If your system is stable now, it should still be stable after adding those.

But you are approaching the limit on that PSU - if you put anything further in, I would upgrade your PSU to something bigger and a better brand-name.

For a system using a single GeForce GTX 550 Ti graphics card NVIDIA specifies a minimum of a 400 Watt or greater power supply that has a combined +12 Volt continuous current rating of 24 Amps or greater and that has at least one 6-pin PCI Express supplementary power connector.

Total Power Supply Wattage is NOT a crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important.

What is the model of your Cooler Master 400W power supply?

Elite Power RS-400-PSAR-J3/-PSAP-J3, combined +12 Volt continuous current rating of 23 Amps.
Extreme Power Plus RS-400-PCAR-A3/-PCAP-A3, combined +12 Volt continuous current rating of 23 Amps.
Real Power Pro RS-400-ASAA-D3, combined +12 Volt continuous current rating of 25 Amps.
GX Series RS-400-ACAA-D3, combined +12 Volt continuous current rating of 30 Amps.

The Elite Power and Extreme Power Plus series are Cooler Master's low end junk and don't even meet NVIDIA's minimum specified power supply requirements to power a system with a single GeForce GTX 550 Ti. The biggest problem is actually the very high electrical noise and ripple on the output rails that will rapidly degrade the electrolytic capacitors on your motherboard and graphics card's power circuits.

I think it is Elite or Extreme one.. I bought PSU included cooler master casing.. I bought another fan today and system is stable.. Will there be any future problems? Should i upgrade my PSU?

You should probably upgrade your psu...

If you are wanting to keep costs as low as you can, this is a current good deal:

http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026

However there is limited upgrade-ability with that unit.

That is of course if you can get newegg where you are. What is your budget/country and we can give you a more specific recommendation.

I am from Sri Lanka.. I bought my PC just two Weeks ago.. So i can't just throw away two weeks old PSU unless it is absolutely necessary.. If I should buy a new psu i can afford like 8000 Sri Lankan Rupees ( =70US Dollars ).. My Current System is stable and i wont do any upgrade ( except a ssd ) for at least 1 year.. What should i do? Should i really need to upgrade my PSU now? ( No newegg )

It's only a should and not a necessity.

You can probably run it now without too much damage to your components, and just upgrade at a later time. Perhaps when you add the SSD.

That means it could damage my components?

As ko888 said it *can* damage the capacitors on your card. It can depend a lot on the specific unit you have, and what its power output is. In general the low end Cooler Masters are not good.

That's not what I said.

I said it will degrade the electrolytic capacitors because that is what high ripple on the DC output rails do. It may take a few months before you start to notice the side effects but it will happen.

I have decided to buy a new PSU..

1. http://www.corsair.com/power-supply-units/gaming-series-power-supply-units/gs600w.html

2. http://www.silverstonetek.com/product.php?pid=294&area=usa

3. Antec 450W PSU which i don't know the exact model

These three are affordable.. Corsair one cost more but it is in stock.. Silverstone one is out of stock and it will be restocked after two weeks but it is 13US Dollars cheaper than Corsair one.. I don't like to wait 2 weeks until silverstone arrive as you mentioned my current psu will damage the components.. Also I don't want to buy a cheaper psu and face the same problem again..

1. Should i wait two more weeks and buy the silverstone psu? ( because 600W is more than enough i want and why should i spend 13US Dollars more )

2. Is 450W enough for me? Antec is a good brand?

 

[lakshitharxx]

Corsair - 97US Dollars
SilverStone - 84US Dollars

 

[lakshitharxx]

Guys please i want to know this fast.. because i am going to buy a one tomorrow..

 

[FinneousPJ]

I'd get the Corsair.

 

[lakshitharxx]

I was thinking about the same.. Casing is cooler Master elite 335 and can i mount new psu into that?

The Cooler Master Elite 335 (RC-335) accepts standard ATX PS/2 form factor power supplies.

The Corsair Gaming Series GS600 (CMPSU-600G) is a standard ATX PS/2 form factor power supply so it will have no problem fitting into that case.

 

[lakshitharxx]

I bought a Corsair 600W.. Thanks guys..

Awesome, at least now that's one less thing to worry about. It's going to power your next GPU upgrade easily, too.
