Help choosing appropriate power and model for PSU

[Dantwz]

Hi guys! I'm a noobie at DIY computing, and I've been trying to settle on different components for days now. My current choice of components are as below (prices are in Singapore Dollars so no I'm not being ripped-off xD):

i7 3770 + Gigabyte GA Z77X-UD3H ($602)

NZXT Phantom 410 ($155)

Kingston HyperX 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) KHX1600C9D3K2/8GX ($69)

MSI 660Ti Power Edition Overclocked ($489)

Hitachi 1TB SATA-3 7200 HD ($90)

My next problem is picking a PSU - would you guys recommend a ~650 or ~750W PSU? I MAY consider overclocking and a new GPU, but even then - would I require a 750?

Either way, I'm looking at several highly recommended options:
Antec High Current Gamer 750: $149 (quite cheap for this power I guess)
Seasonic X-660/760: $168/$189
Corsair TX-650W/750W: $133/$159

I'm really getting confused by the choices available (especially since the seasonics are gold rated (vs the bronze rated corsairs), and would appreciate some help on the matter.

Oh and if anyone could help me find better components for a cheaper price (the reviews mostly recommend those parts I picked so I'm apparently getting quite a lot out of this system. I THINK), recommendations are highly appreciated!

Thanks very much in advance for the help! ^.^

Hi Dantwz,

Please pick up the TX 650. Its an awesome PSU for a low price.

You do not need a PSU with a higher wattage. I am running my i7 2600K @ 4.6 GHZ along with my 7870 overclocked on a HX 650 along with a Corsair H100, multiple HDDs and 3 additional fans.

You will be good to go.

Regards,
Prashant

On a side note, are you picking it up from Sim Lin? I need to know a good place in Singapore for PC parts.

Taking a trip there for Christmas and building my brother in laws rig there for him.

Thanks in advance.

Hey thanks for the response! Although I was wondering if the ivy bridges consume that much more power than the sandy bridges that I would need a 750W... .__. And why'd you get the HX and not the TX? Thanks >.<

And yeah I'm goin there too! There are quite a few although it's recommended you go to the shops on levels 4 and 5. The lower level ones are notorious for ripping people off and scamming them. My friends say Fuwell is not too shabby, with good service and reasonable prices. Video Pro has pretty lousy service but the prices are sometimes better.

From personal experience (ie following my dad around) - try bringing a pen or highlighter along, and collecting flyers and price lists from as many shops as you can, then picking out the lowest and buying the individual components. Almost all the shops have price lists.
