Hello, i'm looking for a good quality psu for my first build and as i'm a newbie and my knowledge is pretty much limited to playing games i would like to hear your suggestions.
I'm on a budget here and therefore can't really afford the most epic supadupa psu's out there.

My budget is ~100 dollars

It should run GTX 580, i5 2500k, and a few hdd's

I ain't gonna overclock my system(mainly because of the lack of knowledge) and i ain't gonna add another 580 but still... some room would be nice

The case is going to be fractal design define r3

Modular or non modular?...does it matter?


Thanks c ya
 
Solution
yes the modular is a big advantage, it will limit your cables inside, more cables blocks the airflow, if your psu is modular you will only connect what you need.
non modular looks messy and will cause bad airflow. there are many good and bad psu out there, the cheap ones usually are generic ones, and the branded is good but the price is too much. one that best balances the quality and price is the FSP. its the best in terms of price performance ratio. buy the FSP everest 800w,
best for your 100usd.

I researched PSU’s before I built my new PC, this one is the one I chose. It had very good reviews and was a decent price.


Corsair 750w Professional silver

The TX is a bit lower in performance but a very good PSU

Conclusion from his review

The Corsair TX750W is one of those power supplies that everyone dreams of having but until now this caliber of performance was far outside of their budgets. This power supply completely bucks the assumption that the most stable power supplies are reserved to those few who have over $200 to spend on a single upgrade. Not only does the TX750 offer performance which is head and shoulders above some highly-regarded 850W units but it is priced at a mind-boggling $150. Even though the price will make you initially wonder at the quality of Corsair’s new offering, the tests prove that a new bar has been set in the price / performance category. All the greatest performance numbers wouldn’t mean much if the company providing the product left you high and dry without a warranty or tech support. Corsair comes through here as well with a 5-year warranty along with an active support forum and quick technical support.

antec earthwatts 750W Modular 80+ silver PSU, $90:

Could someone please clarify this.
"During the Transient Load tests each time the 12v rail was loaded directly that 12v rail fell like a bird out of a nest with a peak change of ~450mV. This is horrible. (I tried to think of a better way to say that but it just "sucked.") To make matters worse, even an unloaded 12v rail that was not part of the same pairing of 12v power components dropped by ~200mV when another 12v rail was loaded. That is just plain ugly. So while an overall decent unit in our standard load testing, the Transient Load Test for this unit are a serious let down."
 
For a single GeForce GTX 580 graphics card system a 600 Watt or greater power supply with a +12 Volt current rating of 42 Amps or greater and with at least one 6-pin and one 8-pin PCI Express Supplementary Power Connector is recommended.

The The Corsair Enthusiast Series CMPSU-750TXV2, that you have linked to, with a 62 Amp current rating on its +12 Volt rail exceeds the recommended specifications so it gives you plenty of headroom. This model also uses Seasonic as the OEM.

jonnyGURU.com's test review of the Corsair TX750 V2 750W is here :

Another letdown of the Antec EarthWatts EA750 is that the +12V ripple and noise are close to ATX limits. High electrical noise and ripple is not a good thing as it rapidly degrades capacitors by overworking them.

Its modern equivalent is the Antec EA-750 Green and it's more efficient and resolves the high noise and ripple issue. It also has a higher maximum combined +12 Volt current rating.
 

Great choice.

Hardware Secrets was able to draw 931.2 Watts from the XFX PRO750W (P1-750S-NLB9) when they performed their overload test to see the maximum that could be pulled from that power supply.

I have now chosen the XFX XPS Black Edition 750W as my dream psu.

I can get it for a reasonable price - it's cheaper than the corsair tx750 even though it's semimodular :eek:
The vomit green fan is pretty interesting :heink: , but because my case has no side windows i think i can live with it...

But anyway, thank you for all the info and guidance :)


Peace out :hello:
