1300+ Watt Platinum PSU's?

post #1 of 58
Thread Starter 
I currently have an Antec HCP-1200 running my setup in my sig. I think I may be straining it quite a bit. Pulling 1500-1600-watt from the wall. With that much strain on the PSU I figure it is most likely around 85% efficiency using around 1330 watts. According to JhonnyGuru the HCP-1200 is a great PSU and gets around 87% efficiency at 1200 watts.

Was hoping to get into the 89% range while using 1300-1400 watts. Is there any PSU that can do that? I have an email in with Antec about their HCP-1300 Platinum to see if that is going to release anytime soon. Really the only PSU I can see that currently is available that would do close to that number is the Lepa G1600 which does 89.2% efficiency at 1276w. That is pretty impressive and Johnny loves the Lepa (especially for only a Gold rated PSU):

Anyone thing the EVGA NEX 1500w would be able to put up as impressive efficiency numbers as the Lepa G1600? What about the Antec HCP-1300 Platinum? According to Johnny the HCP-1000 Platinum earned an 89.3% efficiency at it's max load of 1000w, so that looks promising for the 1300 Platinum. Plus I think those are Delta units which are top of the line. If the Lepa G1600 is doing about the best you can find I will just go and buy that now.

The Lepa actually shows better efficiency than the new Corsair AX1200i at 1200 watts load. Any thoughts/recommendations or any PSU's that I should also look at for my 1300-1400 watt 89% efficiency goal?

I THINK there's a 1500W Platimax, don't quote me on that though.


EDIT: http://www.google.co.uk/products/catalog?hl=en&client=firefox-nightly&hs=qGE&rls=org.mozilla:en-US:unofficial&q=1500w+platimax&um=1&bav=on.2,or.r_gc.r_pw.r_qf.&biw=1920&bih=978&ie=UTF-8&tbm=shop&cid=9361402601070105561&sa=X&ei=PVoxUPDBDoLQ0QXb5YDgDA&ved=0CDoQ8wIwAA
Only 220VAC it seems which is a damn shame. You'll probably need a transformer.

EDIT 2: Enermax's website designer needs to be fired. I want to see if it's 220VAC only!

EDIT 3: It is 220VAC only. Get a transformer. Oh wait, that makes it under 89% efficiency.

220 only! What the.. I know 220 is better than 110 for efficiency but they are limiting their market quite a bit there.

But ya those posted numbers are great is because it only runs at 220 which gives higher numbers to begin with. Transformer would waste any gains. Looking for the best 110 unit. wink.gif

I think for 110v that Lepa G1600 is going to be hard to beat at my power levels.

Yep, as I noted.


http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story2&reid=301

This one's a bit lower, but OklahomaWolf's in Canada so all testing should be 110V. He's probably going to sell a fixed version here, with all soldering done perfectly.

Oh man I see that the Lepa doesn't have a power switch. Who doesn't put a power switch on a PSU?!? Seems silly to have to pull and insert a power cord while working with your hardware.

Now you have to use an antistatic band eek.gif oh noes

I have the lepa 1600 and I have no problem running quad 7970. I didn't overclock them yet because I just built my rig and trying to figure out an eyefinity problem.

I bought it from OklahomaWolf.

Edit: Just read...YES the lack of a power switch is annoying especially with watercooling wink.gif But I can easily live with it.

How do you like the build quality?

Its the same thing as an Enermax, except for the power switch. I really like it. It is very small too. It was perfect for my needs.

I need to point out that sometime under stress it does a small tickling sound just like Coil whine from a GPU capacitor. I only hear it if my head is close to the PSU and this never happen.

Stick to the HCP 1200, you're not "straining" it, it's perfectly capable of dealing with such loads.... and currently there's no unit on the market that would return similar electrical performance at the loads you're using it. The G1600, while an excellent unit, will only offer you marginal better efficiency over the HCP, nothing else... and really that's not worth a ~300$ investment.
Wait for new product launches, there's the SuperNOVA 1500 from EVGA, the HCP 1300 from Antec, the Silencer MKIII 1200 from PCP&C (which will most likely overload like a champ, in good Super Flower tradition) and others.
