What are modular PSU's and which one to get?

post #1 of 11
Thread Starter 
so im wondering what a Modular PSU is. seen plenty of them round but never really wondered what the benefits are. The many members of overclock.net seem to have them in all of there worklogs, gaming pc's and home pc's so they must be good!

1. What are the benifits of the "extra?" cables coming from a seperate spot, instead of the 24pin connector?
2. Can you plug in "Y Splitters" to the extra plugs. for example: 2 molex - to create a 6pin.
3. Is it really worth getting one?

So if they really are as good as i assume they are then which one should i get?
I am in the process of doing a rather major haul.
Case: HAF X.
MB: Gigabyte GA MA790XT UD4P (or better when the bulldozer gets released)
CPU: probablly a HexaCore AMD Bulldozer.
GPU: ATI Radeon 6870. possible CrossFire
RAM: 4GB or 6GB DDR3
Cooler: XSPC RASA RS360 water cooling kit.
HDD: 1 stock 500GB 700RPM (i think)
Possibly a fan controller coming into the mix in the near future.

those would be the components i would be running.
List of power supplies at cheapest retail prices withing my country.
The following prices are in New Zealand currency ($NZ)

Link to list: http://pricespy.co.nz/category.php?k...ev=1#prodlista

id like to keep the expense at below $230

Thankyou in advance guys!

modular PSU gives you more choice on the wiring you want in you're case and improve cable management and thus airflow in the case . it's eay to work with

Sleeving the cable on them is a breeze compared to hard wired PSU.

I assume you could put a Y splitter but most power supply these days have an 8 pin and 2 6+2 pin ( or more )

It is worth every penny to get a good one .

and there's not much diference in performance than a hard wired one

The main benefit of modular PSUs is you can take off what you don't want. For example, I don't run anything off molex cables currently. On my Corsair 450 which was non-modular, I had to route 5 extra lines out of the way for better airflow.

On my Corsair 750 which is modular, I have 5 lines. I have the 20+4 line, the 12v line, two pci-e lines for my video card and a sata line that powers my HDD and my CD-rom. That's it! Every line is used. None of the other lines are needed and they stay in the bag corsair gave me.

Now, I should say the 12v line and the 20+4 line are not modular but I needed them anyway so I don't care.

for your budget, the Thermaltake toughpower 750w is a good bet, but if you can squeeze out the dough i would highly recommend the silverstone strider 850
http://pricespy.co.nz/product.php?p=524875

silverstone PSU's are great quality units and if you do plan on crossfiring in the future you will need at the headroom that the 850 watt unit provides, plus its 80plus silver so it has a decent efficiency rating.

I can get one of those with the bonus "short cable" pack for $100 cheaper (aprox US$60) but its almost 2 years old.

worth it?

Your best options under NZ$230:
http://pricespy.co.nz/product.php?p=416703

http://pricespy.co.nz/product.php?p=424205
I included the 750W just in case, but you would be perfectly fine on a 650W unit. Anything beyond 750W would be wasteful.

I know Antec and Corsair are exemplary. SeaSonic is also a company that stands behind its products but I've never dealt with them directly as I've only owned units made by SeaSonic but sold by different companies (such as my current XFX unit).

I assume your XFX unit runs fine?
also how about this one: http://pricespy.co.nz/product.php?p=312040
