Power Supply Need Help

czechkozen · Apr 18, 2013

Im planning to buy a power supply that can handle my gaming rig.. is Huntkey x7 900w good enough for my Palit Jetstream GTX 660 ti.? is Huntkey a good brand psu.?

Chairman Ray · Apr 18, 2013

I have never heard of Huntkey before. I looked the brand up on http://www.eggxpert.com/forums/thread/323050.aspx, and it is listed under the following heading:

Tier 5 - Other than the units listed above for any of these brands, NOT RECOMMENDED. Replace ASAP if you have one.

So I would probably take their advice and not buy a Huntkey PSU. If you want a good PSU, get a 80+ certified one by Seasonic, Antec, Corsair, or any of the models recommended on that thread. You only need a 500W one for your GTX 660 ti.

Huntkey X7 is 80+ silver rated from what i heard.. btw can i use a 12v rail with 18A.? to GTX 660 ti.? 660 ti requires 24A..?

dudewitbow · Apr 19, 2013

im going to assume its a unit with multiple rails

edit: after quickly googling it, you should be fine with it. its not as super hjigh end of units, but it still maintains at least 80% efficiency as rated.

czechkozen · Apr 19, 2013

yep. is it ok to use for 660 ti?

dudewitbow · Apr 19, 2013

yes, you should be fine. It couild easily sli it as well. the onyl downside to the huntkey unit is that under extreme watt loads, its efficiency drops off to under compared to mid loads. but its still over 80+

Huntkey actually manufacturers power supplies. No other company uses them as an OEM so that should tell you something right there. That being said that specific model is reviewed as pretty good by Hardwaresecrets.

It's about twice as much power as you need though since a system with a GTX 660 Ti needs a recommended 450w power supply....

You quite literally need a 900w power supply for 3 x GTX 660 Ti cards in Sli.

czechkozen · Apr 19, 2013

is it ok 12v 18A? for 660 ti? 660 ti requires 24A?

Deleted member 217926 · Apr 19, 2013

It has multiple rails. As I said above it will run 3 GTX 660 Ti cards in 3 way Sli.

Deleted member 217926 · Apr 19, 2013

That unit has 4 x 18 amp 12v rails for 72 amps on the 12v rail total. As you said a GTX 660 Ti needs 24 amps on the 12v rail.

I would be careful, you wouldn't want to overload a particular rail, especially from HuntKey. They're not bad, but I still wouldn't trust one in my rig TBH.

JJ1217 :

Are you serious? Do you actually believe anyone would make a 900w power supply that would not be able to power a low end card like a GTX 660 Ti?? What use would that be exactly? There are no 900w power supplies that only are capable of running 4 HD 7770s. You should read up on how power supplies work a bit before posting in a thread like this. Power is distributed as needed.

Shenzhen Chi Yuan Industrial Co Ltd is Huntkey's registered company name.

They act as the OEM of some models for the following obscure brands:

Chill Innovation
Best Buy brands Dynex and Rocketfish
LC-Power
Tacens

@annort3 sorry my bad. i know its minimum psu requirements is 450watts. and 900watts is over for 660ti but i dont have other choice. just this one. because that's the only available here in my local store. what i really concerned about is it has multiple 12v rail with 18A.. i just want to ask to u guys that if i connect the 2x 6pin in my 660 ti with 12v 18a how my Ampere do i have.? i dont know how to compute that im not good at computation in voltages. don't really have time for that. LOL

Deleted member 217926 · Apr 19, 2013

You are FINE if that is the only unit available to you. Ignore the multiple rail thing. It's not important to you. The power is distributed as it's needed.

czechkozen · Apr 19, 2013

ok thank you. i'll connect it as it is...

I did not know that. I thought Rocketfish was Seventeam for some reason. Guess I should look at the Tom's list more. The updated version is actually pretty thorough.

ko888 · Apr 19, 2013

The MSI GeForce GTX 660 Ti Power Edition is the GeForce GTX 660 Ti card that draws the most power from what I've seen.

It draws a maximum of 15.5 Amps from the +12V rail when it's overclocked.

Huntkey are pretty crap tbh.

Wattage is not nearly important as Amps are on the 12V rail, and considering its HuntKey we're talking about, I wouldn't trust them. otherwise we'd all be running Coolermaster PSU's.

coolermasters upper end units are usable units. its the low end ones that are near unusable. this huntkey unit is one of huntkeys upper units.
