Did I buy the right PSU??

rabeetX · Jun 25, 2012

Just wondering if I bought the right PSU.. Cuz I dont wanna skip on this one. Want to hopefully run this system for about 3-4 years..

http://pcpartpicker.com/p/aMya

Its a 700W cooler master power plus: http://www.coolermaster-usa.com/product.php?product_id=2991&product_name=eXtreme%20Power%20Plus%20700W

Dont know if its a continuous one or not or if it matters..

Please help..
Thanks

Nope. That's a pretty crappy psu.

CM Power supplies are generally regarded as junk due to power supplies like the Extreme power line. These units are typically far overrated, underspec'd, have questionable qualities and componenets, and are far overpriced for what they're worth. They are barely better than the generic psu's that blow up on a whim.

In essence, that CM PSU should be called Extreme Junk since its utterly crap

Stick with Corsair, Seasonic, XFX, Antec, Enermex, PC&P, etc for these companies consistently put out quality power supplies that are well reviewed and have a great reputation for stability and quality.

Hi rabeetx,

This Cooler Master PSU is fine. It is not that efficient but it will get you going. It has a single +12v rail which delivers 52A. It also features Active Power Correction. All in all, it will run your PC just fine.

Mention your PC configuration to help determine the effectiveness of this PSU.

Thanks for the info. Just wondering if you were in my place and wanted to save some money on the PSU.. What would you go for? (Keeping it atleast 700W)

rabeetX · Jun 25, 2012

Sorry here is my PC config: (posted this in OP but didnt mention what it was)

rabeetX :

You don't need 700W for that system. A good 550W would do just fine, but here's my recommendation. http://www.newegg.com/Product/Product.aspx?Item=N82E16817256071

As an aside, the one place you DON'T want to go cheap on is the PSU. Trust me.

SmartGeek · Jun 25, 2012

rabeetX :

If I was at your place, I wouldn't have chosen a 700w PSU. I would have gone with a less watt PSU which can deliver solid and continuous power to the system.

Considering your configuration, I would have gone with Antec 550w PSU as it modular, features APFC and the brand is reputable too---

In that case.. you need a very high quality power supply at the 750w+ range from a highly reputable company. I'll find some for you BUT THESE WILL NOT BE CHEAP. YOU GET WHAT YOU PAID FOR.

Corsair TX750V2

lilotimz :

Oh ***..

Thanks for those links. I didnt know i was making my pc from a recipe of disaster..

Good thing I asked you guys.. I think I will go for this one for now:

http://www.newegg.com/Product/Product.aspx?Item=N82E16817151095

thats a seasonic 620W PSU.. What do you think?

SmartGeek · Jun 25, 2012

rabeetX :

So, you plan to overclock and SLI in the future then you need to get a PSU which has a maximum power of at least 750w or more.

In this case, I would recommend this one---
OCZ ZT Series 750w Fully Modular PSU---$110. After rebate, $90---
http://www.newegg.com/Product/Product.aspx?Item=N82E16817341052

This PSU is very good. It is fully modular, has power correction and has an efficiency greater than 85%. This PSU will definitely last for 3-4 years delivering reliable power supply to your system. It is better than its competitors at this price point.

SmartGeek :

$90 will get you a much better Seasonic PSU! [:lutfij:2]

SmartGeek · Jun 25, 2012

rabeetX :

Hey, you wrote that you have bought the Cooler Master PSU. Is it so? Plan to SLI GTX 570, you need to get a more powerful PSU.

rabeetX · Jun 25, 2012

Since Seasonic is getting more votes I will go with this one:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817151094

I think I will stay with just one GPU until about December so that should work for me..

rabeetX · Jun 25, 2012

SmartGeek :

Yes thats the bad part

I am gonna have to wait 1 week now

Send it back.. buy the new one.. wait for it to arrive.. This is messed up

amuffin · Jun 25, 2012

rabeetX :

Same price for more watts

http://www.newegg.com/Product/Product.aspx?Item=N82E16817139020
Still made by seasonic.

rabeetX · Jun 25, 2012

But the Seasonic is modular which is a plus for me.. and 30 watts doesnt mater that much

lilotimz · Jun 25, 2012

But hey. You know that you are getting a very high quality part that will not cause you any troubles at all. You know that it will last for years and years and is one of the few parts that will live build after build.

My dad bought a quality power supply 8years ago for his socket 478 p4. It is still working today and we had no problem with it (i did... i replaced it with a cx400).

THese modern quality power supplies will ensure your computer is fed with appropriate power and protect your computer in case of something happening.

P.s. Seasonic produces many, many of the well reviewed power supply lines other companies sell. Corsair, a well known psu company, uses seasonic in most of its units such as the TXV2,HX, and AX. XFX uses all seasonic units. Antec uses quite a few seasonic designs etc etc.

As long as you get a high quality power supply that can power your computer efficiently and safely; you are safe.

SmartGeek · Jun 25, 2012

rabeetX :

That 520w SeaSonic PSU can't handle GTX 570 in an SLI setup. I suggest you to buy a 750w PSU if you plan to SLI in the future.

Thanks man Seasonic PSU it is! FU cooler master

SmartGeek :

Im gonna buy the 620W for now..

lilotimz · Jun 25, 2012

620w is still pushing it for GTX570 in sli. It'll do it but it'll be kind of close.

An i5 system with dual gtx570 usually takes in around 450-500w under heavy load and dips over 500w at peak load. Gaming load should be around 300-400w but it's still very high. I would not recommend any overclocking at all if you do get the Seasonic 620w unit. It will work but it will be close!

SmartGeek · Jun 25, 2012

rabeetX :

Here is Guru3D's power supply recommendation:

GeForce GTX 570---
On your average system the card requires you to have a 600 Watt power supply unit.

GeForce GTX 570 in SLI---
A second card requires you to add another 225 Watts. You need a 850+ Watt power supply unit if you use it in a high-end system (1 KiloWatt recommended if you plan on any overclocking).

But a 750w PSU will be ideal because I have seen many people running GTX 570 in SLI on just a 700w PSU!

Now the choice is yours!

SmartGeek

rabeetX · Jun 25, 2012

Ok.. I got it.. That means I should be fine for a single GTX 570 with 620W then..

Did I buy the right PSU??
