Cheapest PSU to Last 4 Years: i5-3570k and Radeon 7870

[ROUGHRIDER13]

^title

I will overclock at some point and would like to have headroom for crossfire.

Please note CHEAPEST!

Thanks

Any of those have headroom for crossfire and they're the cheapest with good quality you can find :

I'm USA, was asking because NCIX is a Canadian site.

If you want it to last 4 years, you should get a five year warranty. You will have to pay for that.
Look, I've said it at least 100 times; DON't skimp on the power supply!! You will find other places to save money on your build but don't try to save on the power!!

You want to crossifre with a cheap PSU??

facepalm

No, it's in us dollars, it's the us ncix site(http://us.ncix.com), not the ncix canadian site.

I do not intend to skimp on my power supply. I just don't want anything overkill.

I never said I wished to purchase a "cheap" power supply, I said I wanted the "cheapest" for my needs.

Where do you suggest I can save money elsewhere on my build?

 

[djangoringo]

The ones i recommended, are all quality psu with enough room for two 7870, they're the cheapest in the sense of the best quality/price.

The SeaSonic G Series SSR-550RM 550W will be more than enough for your AMD 7870 and Intel i5-3570K.
Stable voltages, 5 year warranty, 80 plus gold efficiency (you will earn back money and more in 4 years on electric bills compared to bronze efficiency) for a price of $79.99 +$10.18 S/H.

If want the cheapest up-front cost from a repeatable PSU brand than CORSAIR Builder Series CX500 500W will do:

what is your build?

 

[dudewitbow]

http://ncix.com/products/?sku=59615&vpn=P1550SXXB9&manufacture=XFX&promoid=1285

something along the lines of this would be adequate for non upgradable use.

 

[ROUGHRIDER13]

what is your build?

Still working out the specs, but something like:

Intel i5-3570k
Cooler Master Hyper 212+
Some <$100 Z77 Mobo
Some low profile 4 GB RAM
Western Digital Blue 500 GB
XFX Core Edition Radeon 7870
Zalman Z9 Plus
Some quality PSU
Some cheap optical drive
Windows 7 Home Premium 32 bit

 

[djangoringo]

Here's a good z77 mobo under 100$ : http://www.newegg.com/Product/Product.aspx?Item=N82E16813130646&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-na-_-na-_-na&AID=10446076&PID=3938566&SID=

I recommend going with 8GB ram : http://www.newegg.com/Product/Product.aspx?Item=N82E16820147096&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-na-_-na-_-na&AID=10446076&PID=3938566&SID=

You could get the xfx 550w like the one dudewitbow linked, if you don't plan to crossfire the 7870.

Ok so what we know is you want enough headroom to possibly run crossfire/sli. To accomplish that and still leave yourself enough headroom for a possible overclock and to make sure your PSU is not over worked You will likely want something around 700-850watts.

Is that the cheapest tier 1?

Also, what makes certain power supplies better than others? The 80+ rating? There are 80+ Golds on Newegg for the same price as the one the guy I'm quoting recommended, which is 80+ Silver....

I'm confused.

its sorta because the list on eggxpert is slightly outdated. some of the units on the list are discontinued.

Hi,

I`ve also been looking into buy a new psu and was adviced to get somthing from seasonic or xfx core series. Check out the following wesite for reviews


http://www.jonnyguru.com/index.php


what make a good psu?

good quality caps

design

build

I was also told to stay away from carsair which would have been my choice of brands as they have recently changed there suppliers.

corsair doesn't change their suppliers, they have more than 1 provider depending on the specific unit. Most psu brands done even generate the base model for their psus, which they contract another oem to base a model, and make follow up modifications to the said unit. You just have to know which specific unit is good, and which is not. Realhardtechx has a pretty updated list of reviews for several units from several brands which is good to look through, as it tells you information on rail wattage, the original OEM and such.

Hi,

Thanks for the website plenty of info.

the corsair model I was looking at was the tx850 which used to be made by seasonic but now made by ctw which don`t seem to have such good reviews

 

[ROUGHRIDER13]

At this point, I'm mightily confused, so I decided to look at some other i5-3570k/Radeon 7870 builds to see what they recommended. My questions now are:

How much wattage do I need? (Remember I want to crossfire and overclock at some point)

Which 80+ rating has best price-performance? My guess is 80+ Silver.

If I were to find three PSUs, one 80+ Bronze, one silver, and one gold at the same price (theoretically) with enough wattage, would the 80+ gold one always be better?

Thanks, and Merry Christmas.

 

[djangoringo]

Get this one : http://us.ncix.com/products/?sku=62224&vpn=P1750BNLG9&manufacture=XFX&promoid=1285

It's seasonic oem, tier 1 quality psu, 750w plus silver modular(enough juice for two 7870 or 7950 oc+whatever cpu+couple of fans+hdds,ssds,etc).
And it's the cheapest you'll find.
Merry Christmas to all.

I'm confused.

The rating gold/silver/bronze just is a benchmark to show how efficient the PSU is. All it measures is how much power the PSU outputs at different input levels. It has nothing to do with the quality. Quality is determined by design, components used, build quality and warranty. It may or may not be the cheapest tier one depending on sales. It just seemed to be a good buy on the site I looked at.
