Choosing a good PSU

[chanuka3949]

Hi, I'm planning on buying either a Sapphire R9 280, Zotac GTX 960 or a  Asus GTX 760.

 

Here are my Options

 

FSP Aurum S 500W - http://www.fsp-europe.com/aurum_s_500.php

Seasonic SS500BT - http://www.seasonic.com/pdf/datasheet/NEW/Bulk/PC/ATX/SS-XXXBT%20Active%20PFC.pdf

FSP Hexa + 550W - http://www.fsplifestyle.com/product.php?LID=1&PSN=1002

 

Both FSP PSUs are Haswell Compatible but the Seasonic ins't. Would that make a huge difference in energy saving.

 

Targeting to use the PSU for more than 5 years.

 

Which one is the best option. These are the best options in my country. And online shopping is not an option

 

Thanks in Advance

you don't, strictly speaking, need one of these "Haswell-ready" PSUs to build a Haswell system. Corsair told us that it "fully expects" motherboard makers to let users disable the new low-power power state in the firmware. Cooler Master went even further, stating that, to its knowledge, "all mainboard vendors" will disable the new low-power state in their boards by default. In other words, you may never encounter any issues even if you pair a Haswell platform with an incompatible power supply.

 

Note the "may" and "expect" and other weaselly phrases.bet hedgers

Many Shops are bad in after sales support. So the warranty doesn't mean anything, therefor the PSUs listed are the only ones sold(that could deliver enough power) by good shops.

Technically, none of them should be "Haswell-Ready" due to the extreme testing methodology of Intel. Regardless that extreme test is highly unlikely in the real world, and you should not need to worry.

 

Between those three, I would forget about the Hexa. Between the Aurum S and Seasonic BT OEM unit, it would go for the Aurum S due to higher efficiency, a FDB fan, and its longer 5 year warranty. The OEM version of Seasonic tend to come without a power cord and uses lower quality caps than it retail counter part as well.

But this site show that it uses "Capacitor used is brand nippon Chemicon with SMQ type size 400v / 270uF 85ºc". Isn't that a good Cap ?

That's the primary cap.  In the secondary side, it uses Teapo which is acceptable, but the Aurum S does used full 105C Nippon Chemi Con.

[chanuka3949]

The other products in the aurum gold series use 105c japanese caps. But they don't use them on the aurum s series PSUs. Can't find the link but saw that there are capxon or teapo caps. They don't even advertise that they use japanese 105c caps on the aurum s 500.

The AS-550 uses 105C NCC KZE on the secondary side. There seem to be a Rubycon (Japanese) in there as well. They don't advertised them on their site either on the 550w model. I did made a mistake, however. The Aurum S does not used an FDB fan but rather a sleeve bearing fan.

 

Up to you. They are both budget oriented power supplies, but one has better caps and efficiency, while the other has a better fan. Both of them are group-regulated, so don't except great voltage regulation off of either of them.

I will choose Aurum S 500
