Supermicro-Ablecom PSUs

Re: Supermicro-Ablecom PSUs

So, the Etasis built units you reviewed turned out o.k? I'm trying to understand if this is a general trend these days. In other news looks like PCP&C are coming out with a 700W budget unit with 60A on the 12V!

Jonny, buy it man. Take one for the team!

Also a Seasonic, I see - worth testing in any case...

but ARGH that colour!!

[Super Nade]

Re: Supermicro-Ablecom PSUs

Yes, horrible mud colour. The ripple and other specs on paper are looking good. Now all we have to do is to get Jonny to buy it.

See for yourself:

Got a little jagged during test 4, but that's 539.6W. And never quite 100mV (pretty damn close.)

Not any better or worse than the Ablecom. Really about the same. And certainly not as bad as the OCZ. The OCZ was showing the 100mV on all rails during all tests.

Re: Supermicro-Ablecom PSUs

I like the near flat 12V line you had with the ST60F=YES!

Re: Supermicro-Ablecom PSUs

Thanks for the test Jonnyguru and Supernade!

Thank Jonny, I just bought the unit. He did all the work.

Galvanized, I'd love to see what happens with an XTX CF setup. I've ased a member over at ocforums to loan me his XTX CF card pair. Somebody else loaned me a Prescott and a pair of WD Raptors.

So far I have the following to mix and match:-

3 Opticals
4 HDD's
1 x1800xt
1 7800GT
1 Prescott
1 Opteron
Some DDR2, 1 set of BH5
120mm fans
I'm trying to get somebody to loan me a Cold Cathode setup. He said they draw from the 5V, but I'm not so sure.

Any particular test procedure you guys would like to see?

CCFL's that use the 5V?!?!?!? That's odd.

Re: Supermicro-Ablecom PSUs

Super Nade Dude,

http://www.bgmicro.com/ > resistors > pg.34. They offer 2ohm, 25W ceramic ballast resistors for $0.49 each Do the OHM's Law math. They have 10ohm, 25W also...same price. I bought some just for fun&games. Everyone needs extra bits&bobs around

Shoot! That'll load down a PSU.

[Super Nade]

Re: Supermicro-Ablecom PSUs

That is exactly what I told him. But he insists on that being the case.

Galvanized, I'll pick up some of those high wattage resistors. Going by their price, it should have a tolerence of about 50%. If that's the case, it would suite the tests perfectly.

[Galvanized]

Re: Supermicro-Ablecom PSUs

2 or 10 ohm, tolerence is 5%...Sorry

The quality ain't all that bad.

[jonnyGURU]

Re: Supermicro-Ablecom PSUs

Well, screen shots didn't do the results justice so I'll just have to describe them to you.

Too bad Easyscope II doesn't make movies!

Because I wanted to use dual 12V rail PSU's that could handle a 14A load on each 12V rail, I grabbed an Ultra X2 550W and a Thermaltake TR2470W.

I actually increased the sample rate to make the waveform more fluid.

The Ultra looked like the Coca-Cola dynamic ribbon device. The Thermaltake looked like waves coming up from the Gulf during low tide.

The Mushkin HP-550 looked like a insomniac with cerebal palsy and turret syndrome having a seizure in a bed strapped to a roller coaster.

That's really the best way I could put it you all. Sorry if I offended those with insomnia, cerebal palsy, turret syndrome or those with beds strapped to roller coasters.

[Galvanized]

Re: Supermicro-Ablecom PSUs

So the Mushkin ain't really enhanced

(note to those that don't know...Mushkin calls this Topower built unit Mushkin Enhanced. This has nothing to do with the real Enhance brand )
Sorry jonny, I had too.

[jonnyGURU]

Re: Supermicro-Ablecom PSUs

No problem. Yes... These are NOT made by Enhance and have nothing to do with Enhance. They're simply called "Enhanced."

[Super Nade]

Re: Supermicro-Ablecom PSUs

Jonny, what is your take on their "Rail Fusion" spiel? Is it just marketing BS? Do you see any circuitry inside to back this up?

Enhanced, as in ripple-rich.

As you know, most multiple rails comprise of a single 12V source that splits off separate circuits with a diode and/or VR, an IC, etc. Whatever flavor the OEM wants to use as long as the circuit is isolated from the others.

What Topower uses is just a little inductor coil between each output circuit. So you have two circuits that are isolated from each other as far as EMI goes, but voltage still travels through the coil to the other rail.

It's really strange. Because they say each rail can do 20A. Well, obviously each rail can do more than that since each rail is only isolated by a coil. Obviously they only say that so on paper they can be ATX12V compliant.

The label says the combined output of the 12V rails is 28A. I can put 14A on each rail. If I put all of the load on one rail, I can only do 27A (at 27.5 and up, the PSU trips off.)

Hmm.....

Re: Supermicro-Ablecom PSUs

So, currentwise, it's not multi-rail at all, it's just a single rail which has a few outputs bridged by inductors. And now you say it isn't even able to put out the rated 28A at all, so....

Would you expect a similar scenario to apply to the "44A" Mushkin PSU, also claiming "rail fusion" capability?

And who came up with the "Rail Fusion" line? Sounds too much like something out of my kids' "Dragonball Z" collection for my liking.

For the record, I don't think my judgement of the HP should reflect on the HX series Mushkin PSU. Topower has proven that they are capable of a full range of product quality.

They would charge a bit more for Super Ripple-Rich feature.

Hmm.....

And I was thinking in terms of active relays etc....

Did it trip up in your hot or cold test?
