Whats the best ps for mcx 462-ut

[fatcat]

This is my first thread here, although I have been doing alot of reading & gathering of information forn this forum.
I am setting up a new water/pelt cooling system & it is finally running. I have a mcx 462-ut waterblock/pelt with a Mean Well S-320-12 12V power supply.
I was reading a thread in which Player0 was talking about the
S-320-12 being under powers for the job.

Does anyone know what a better power supply is & where it can
be obtained on the net ( usa/ canada) ?

hmm i think 320 is OK, but if u want more power fully supply u can get meanwell s-350-12 with 29A on 12v. that's whati got

Hello and :thumbsup: :thumbsup: Welcome to LiquidNinjas :thumbsup: :thumbsup:

It appears Yaboc has already answered your question so I'll leave it it that :)

[fatcat]

yaboc, where did u get your meanwell s-350-12 ?

[Player0]

If you have a quality ATX powersupply with the proper power rating for the 12v rail (at least 33a or higher) then you can run the peltier right from that without the additional powersupply.

The meanwell 350 series is new, so you might not find them through cooling dealers, but you can do a google search and find some reputable places, or use Meanwell's dealer locater.

The 320 series has enough power to run the peltier as well though, but the 350 will be more stable.

My point about the 'underpowered' part is actually the voltage. Running the peltier with a 12v powersupply is only using 75% of the peltiers potential. A 15-16v powersupply would be best, although it needs to have a much higher amper rating.

thanks for the info Player0. This 320-12 puts out the heat, good thing I have it sitting on top of my pc. I was just wondering if a bigger ps would resolve that heat issue abit.
Oh by the way, nice change of pics . . hehehhe

[Player0]

Yeah, it might help stay a bit cooler, the 350 that is :)

hey fatcat i can't tell you how hot it gets as i 'm still waiting for the pelt for my cpu block. i got mine off ebay but it's cheaper than S-320 because there's only 2 year warranty on it instead of 3 (s-320)

Running the 226w pelt at more than 12v will definitely get you more cooling capability. Just know that you'll need very very good water cooling to handle it. If you have only "good" cooling the heat generated from the hot side of the pelt running at 15v can be overwhelming.

I used to run my Meanwell S 320 at 13.2v by adjusting the dial at the back of the PSU which allows for +/- 10%. I found running the S320 maxxed at 13.2 worked best for me in the long run. I tried a 15v and it was just too hot and my water temps went too high...I ended up with no gain over the 320 and sent the 15v back (it was very expensive).

lets say i had was using the Swiftech MCW50 for my gpu and the Swiftech MCW5000-PT for my cpu and i had a swiftech mpc600 pump, with a thermochill he120.3 radiator. Could i then run it effectively at 16v?

[Player0]

Its all about pump. Id say yes, definitely, with that set up. The main problem with pelt clocking is the waterblocks themselves. You want high-flow and high-pressuer on those pelt waterblocks to get decent results.

[mdzcpa]

You never want to run the 226w at more than 15v.

You can certainly get away running the 80w and 226w (at 15v) on the same loop with the cooling you have. However, your fans will have to be loud and push some serious cfm. In addtion, unless you keep the water temps at a sane level, your mcw50+T will struggle.

Looking back at your post, you say mcw50...not mcw50+T. Don't do it. Rule #1 of pelts...never mix pelted and non-pelted blocks on the same loop. In your example the water temps from the 5000PT will be far too high for the mcw50 to be effective.

[wfarid]

oops i forgot the T sry, they are both gonna be pelted

[wfarid]

so i couldn't do it with like 3 silent fans that have like 23cfm each?

[wfarid]

correction i meant 76cfm (he120.3 takes 120 mm fans, i forgot about that)

[mdzcpa]

Three low cfm fans won't cut it with the 226w at 15-16v plus the 80w TEC. When you go TEC, it's very hard to keep it quiet. There's just an incredible amount of heat.
