Please recommend a psu for my new rig

[comp999]

Hi, I am getting a new rig, could someone please recommend some power supply model numbers/ wattage to me from this list: corsair (tx750 bronze, hx650 silver, hx750 silver, hx850 silver, ax750 gold), cooler master (extreme power plus 650, silent pro 850w, silent pro 1000w) or seasonic (x-750, x-650)?

The specs are:
i7 3730k(no overclocking for the time being, i will change the psu when i am going to oc)
Kingston Hyperx Genesis 16 gb ddr3 1600
Kingston Hyperx 3k 240 gb
500 gb hdd 7200 rpm
dz77sl50k motherboard
galaxy nvidia gtx 670
dvd writer

Why will you change the PSU when you decide to overclock? Buy it right the first time and you won't have to worry about swapping it out later. That said, a good quality 500W can power your specs but if you want some headroom for future additions or upgrades, you can consider a 650W as well. The Seasonic X-650 on your list would be my choice.

Thanks, so if the seasonic is not available when I am ready to buy, would the coolermaster silent pro 850 or the corsair hx650 or hx750 be good alternatives?

Also is 650w enough with overclocking?

650W is plenty for overclocking with your specs. There's the Corsair AX650 which is pretty much a rebadged X-650. The Corsair HX line is very good too.

EDIT: This is news to me but looks like the HX line have all been uprated to 80 PLUS Gold. http://www.corsair.com/en/blog/hx-gold/

With only one 670, even a 500watt is fine for overclocking. A 650watt will power TWO of those 670s with overclocking.

 

[comp999]

Just one more question, other than the 2% extra efficiency and the processor plug more modular, is there a difference between the ax750gold and hx750silver?

Where are you buying?

Your motherboard does not support SLI so you will be limited to one graphics card, therefore a 650W-750W power supply is overkill. A 500-550W power supply will easily handle an overclocked Ivy Bridge CPU and one GTX 670.

 

[comp999]

Umm in my country they do not have new gold hx750, only the silver hx750 but they have the gold ax750, coolermaster is the really popular and is the common one here but no one in this thread is recommending it so I am going with corsair. That list above is the availability in my country basically. So basically my question is silverhx750,goldax750 or bronze tx750?

 

[lehtv]

Are you buying online? Link?

What 500-550W units are available?

HX750 is a silver unit, not gold. Not that it matters, the efficiency is above what you need anyway. 80+ Bronze is fine.

 

[comp999]

uhhh for 550 watts only coolermaster extreme power plus is available, btw what is wrong with buying the coolermaster silent pro 1000w?

 

[lehtv]

Available where? You seem to be browsing a website to know so quickly what's available. Please link to that website.

Extreme Powers Plus line of PSU's are crap, don't buy them.

A 1000W power supply would be ridiculously overkill for a rig like yours, it wouldn't benefit you in anyway. If anything, it'd have a negative impact on power quality and efficiency when the system is idling.

 

[comp999]

The corsairs are in a price list they gave me, no I am not buying online

 

[lehtv]

OK. If they really don't have any decent 500-600W units like Seasonic S12II/M12II 520W, Antec Neo Eco 520W, Antec HCG-520W, Antec Earthwatts 500W, Corsair CX600 V2, XFX 550... go with HX650. I'm just trying to help you avoid paying too much for something you don't need. A good quality 80+ Bronze 500-550W unit would be ideal.

 

[comp999]

wait they have the cx600, but no cx600v2, thanks a lot for all the help guys, how do i mark this thread as solved?

 

[lehtv]

Silent Pros are good. Extreme Powers are not.

CX600 is good quality and relatively affordable. It's worth buying if TX650 is either unavailable or considerably more expensive. The V2 is only a minor improvement over the older design, nothing to worry about. Rated at only 480W of +12V, it's similar to less budget-oriented 500W units, but 480W is more than enough for your setup.

 

[comp999]

Thanks, a lot lehtv i ended up buying the hx750, because they ran out of stock for everything else.

 

[lehtv]

I suppose that's the reality of living in Sri Lanka... At least you're covered for any future rigs you may build, enjoy

I'm confused about why you edited out the link. It's no problem linking to stores here

 

[comp999]

Yea, anything that the people here don't normally buy, you will never find it lol. anyway thanks for your help and I will enjoy the rig, lol
