Budget 24pin and Dual 12V rail PSU

[apvm]

This is what I got lately

Altho in a retail box but nothing much inside, PSU, power cable, 4 screws and that's it.

Specifications:

For those who don't know the brand, HEC are the PSU to get 10 years ago, the older Antec 300W were made by them.

The PSU has 24 pin power connector, 1 P4 Style connector, 6 4 pins connector for hard drive etc, 1 SATA power connector, and came with a 4 pin to 6 pin convertor for PCI-E video card. Pretty much enough for a modern PC.

The weight is slightly lighter than the Thermaltake 420W which it replaced.

Advantage of dual 12V rail is the 1st 12V rail goes to the motherboard (24 pin power supply) and the 2nd 12V supply the rest of the connectors, this is useful if you have mutiple drives in your PC, for my case 4 hard drives and two optical drives.

After 5 days of non stop operation, I found it is much stable than the Thermaltake and cooler too, the Thermaltake will feel warm after 5 days but this one is cooler, this only means it can supply enough current to my PC without draining too much on the PSU.

Overall, I recommend this one for those who don't have a budget for a $100-200 dollars power supply. BTW HEC is in AMD recommended PSU list.

The newer Thermaltake (TR2) lineup is made by HEC.

12v2 is for CPU only. 12v1 is for motherboard + peripherals.

I would still recommend the Fortron AX450-PN before an Orion.

Thanks for the info but I read it somewhere that the rail thing is the other way around, may be my memory fail me again.

I know about the Fortron but it is hard to find in Ontario and last week NCIX had it on sale but still it came close to $80 including shipping and taxes.

And to be honest, I have an HEC AT power supply still working after 10 years, so for $30 less, I am fine with the HEC.

Single rail is the way to go

Point being, there should be alarm bells going off when an advertised 585w PSU is being sold for so little.

PSU's aren't being built the same as they used to. HEC is still a good manufacturer but even good manufacturer's have varying levels of quality.

For power hungry systems, a single +12v rail is still best.

Point being, there should be alarm bells going off when an advertised 585w PSU is being sold for so little.

Simply because the name is not well known in N. America but it is rather popular in Asia and Europe.

And if you dig deep enough, what you paying extra for some well known brand has little or none to the performance but the cosmetic.

I always do a lot of research before I buy a piece of computer hardware and I am looking for the most bang for my $, for after my 1st computer a Sinclair Spectrum 48k, I learnt that the worst investment is the mighty PC, they are even worse than cars. The 486 66mhz 10 years ago costed me quite a bit but if I still had it, how much does it worth now and I also wonder if it can run the programs I am running now, at least the Honda I bought 10 years ago is still running fine.

Oh btw, if you open this PSU up and compare it to an Antec 480W and check out the made of components like capacitors, you'll be surprised.

12v2 is for CPU only. 12v1 is for motherboard + peripherals.

I am pretty sure you're wrong, if you check out the specifications of ATX 2.01 concerning dual 12V rail.....

"With a dual +12V PSU, you have one separate +12V rail for the motherboard and then everything else is supplied by the second "rail"
That way the motherboard is unaffected by power surges and dips caused by drives spinning up etc."

[apvm]

For power hungry systems, a single +12v rail is still best.

Wrong again, no matter how powerful your single +12V is, the motherboard is subject to possible power surges and dips caused by drives spinning up. You should do more research, the ATX 2.01 Specs require....24 pin, dual 12V rail and power efficiency no less than 75% and some more minor changes.

Imagine your +12V is a water tab, dual rail is like adding a Y connector to the tab, so if you have 12V1=19A and 12V2=20A, your total 12V=39A, the advantage has already mentioned above.

So a big NO to your quote.

Brand name has little to do to up-to-date enthusiast. I don't feel bad at all for owning an OCZ PowerStream 520W costing $159 + tax. Maybe in your opinion, I'm paying $100 more while losing 65W. Stupid me...

Not necessary, the OCZ PowerStream line is one of the top PSU and you shouldn't feel bad at all but if it was Modstream then yes, it will be no better than the cheaper Fortron or HEC Orion.

And I pity those who pay more for those Ultra X connect series, you are actually paying more for the cosmetic but the power supply is simply not up to high performer PC requirements especially if you overclock, Ultra is consider bad in the following thread http://techimo.com/forum/t124252.html

Let me clarify the purpose of this thread....the thread is to recommend a budget power supply that is ATX 2.01 specification and good bang for the buck.

I have one AMD 64 9x280mhz system with 3 SCSI and 4 IDE drives doing mostly video encoding (home video to DVD) stuff 5 days per week non stop and sometimes 7/24, generic PSU couldn't do it, I have had two so call 500W generic burnt out within weeks with another box doing similiar task. As I mentioned before the Thermaltake 420W simply getting too warm after a few days and that was sign that it may not have enough juice to supply the AMD 64 and it was drawing too much current from it. The HEC Orion after 5 days of non stop operation, it doesn't feel uncomfortably warm and I have to say it is good bang for the buck, cost is an important factor to my line of work, I don't want to buy a $200 dollars PSU that half of its purpose I don't use (like supporting an SLI set up) especially when BTX may be coming soon...but that is just me.

Well yeah, if you're talking about ModStream, 12v is worse than 420W PowerStream. Ultra is even worse, no doubt.

I won't use "warm" to describe the health of the psu. It just a matter of airflow. The HEC may be an alternative to the even cheaper junks, but if I am you, I wouldn't risk the 3 SCSI and 4 IDE drive on a $43 psu, not worth the risk for blaming myself for being cheap on the essential, + I don't trust the 585W at all. 9 x 280 depends on if you're on stock voltage, vcore kills.

Although my psu support BTX, I don't think it's replacing ATX any time soon, more like never.

You cannot add up 12v1 and 12v2 and get your total peak 12v amperage output. That is not how it is calculated.

70% minimum under full load, not 75%. 75% is recommended.

You should look at the connectors page and note what is powered by 12v1 and what is powered by 12v2. If you notice, the only thing that 12v2 is powering is the 12v connector, which is what is powering the CPU. Motherboard, molex, SATA, and all other peripheral connections, they are receiving their 12v power by 12v1. Download it here, and look at pages 35-37.

What the ATX12v spec requires and what is actually out there in the real world can be 2 different things. You may have not overloaded an ATX12v 2.01 PSU with dual rails but I have, and it needed to be replaced with an OCZ Powerstream, which is not by definition ATX 2.01 compliant since it does not have dual rails.

[apvm]

No worry about me, I've been playing around PC stuff since the Sinclair Spectrum days and HEC was a top PSU manufacturer during the 386 or 486 or 586 days (can't remember) and I still have an Antec AT power supply made by them, so I think I know what I am doing. As for the heat it was not airflow I am sure since I have my case open, before the AMD 64, it was an AMD Barton, same component except different cpu and motherboard, so I am sure the AMD 64 draw more current than the XP and for my kind of useage, the Themaltake may or may not endue.

Anyway, I did open the HEC Orion and checked out its components and soldering job etc....altho the components are not top of the line but they are acceptable, at least the capacitors are not no name cheapo stuff which may leak or fail completely after extended use ,the heatsink is not just a piece of metal like some no name generic PSU and the general soldering job is OK.

The cost cutting I see is they use a thin steel casing, Taiwanese capacitors instead of Japanese and the heatsink is of lesser weight but still designed to do the job. ( not a piece of bended metal like some real cheapo PSU). To be honest, I don't expect to find Japanese components and a heavy duty heatsink on such a low cost budget PSU but the things I found inside told me it should last quite a bit before it'll fail.

I am not here to debate, I am here simply to recommend something to the people out there who can't afford Powerstream and want something that is affortable and will not burn out in a few months and bring along some of the more expensive components to power up their PC.

No need to justify your purchase here since nobody is saying the HEC ORion is a better PSU than the more expensive one.

The Thermaltake is well known to be the best bang for the buck 420W out there but it doesn't mean the others more expensive ones are worse than it.

Let me repeat myself, I am simply recommending a PSU which is budget and best bang for the buck IMO here in this thread.

If you want to justify your purchase by bashing this one, it'll be like comparing apple to orange and there'll be no point discussing further, I'd suggest we stop right here and right now and to be honest if you have a Powerstream why bother with a budget PSU, it is simply not for you.

Longevity of a PSU can rely on many factors. That said, I don't believe you have owned that particular unit long enough to make a statement on whether it will last or not.

The TT 420w is a 5v based unit, not very well designed for heavy +12v based systems. A dual core P4 with the same amount of drives that you have, and a high power video card, will bring that down to it's knees. As mentioned, it is a good 5v based unit.

I don't believe anywhere that I have bashed that unit. I said that there should be alarm bells going off when a 550w unit is being sold for that price. "Bashing" is a pretty strong word, and I have never said anything negative about said PSU.

You pointed out several statements I made and deemed them incorrect. I have posted the information showing whether they are correct or not. It is not a debate. The facts are there in the ATX12v 2.01 specification, which you referred to several times.

I am merely posting information. I have never said I have bought a Fortron or an OCZ Powerstream.
