Chieftec 450W PSU...(Delta-made apparently)

[memories2002]

Thinking about picking this up, it costs me about 63$. Im not in the USA, so dont say Enhance 5150! My options are L&C 500W (my current l&c 400W is going up to 13,13.2,13.5V on the 12V line!) or an Antec SP 400W for the same cost. Leaning towards the Chieftec..any way to check if its really a Delta?
Ratings are 28/30/14+15. Active PFC.
Opinions?
Edit : Can also get a Vantec Ion2 460W for about $65-70.

L&C is :thumbsdown:

As of last year Chieftec was built by Sirtec

Sirtec also builds Enlight and is one and the same with HighPower, they are the same company.
To the best of my limited knowledge, Enlight, HighPower and Chieftec are good units, much better than L&C.
Quite frankly L&C is pure crap.

Delta PSUs are very good indeed. You might find one in discarded Dell server.

Is Zippy/Emacs avalible in India?

To answer your question. 22 links down this page is the UL certification. Enter the Chieftec's UL number.

Again, as of last year: Vantec was/is built by Topower. According to the European Mod
over at http://www.badcaps.net/ Sirtec rates better than Topower.
Topower is not to be considered a junk builder.
Bad builders would be Youngyear, Powmax(they build Chiefmax and Chiefman ) and ATNG.

Would this dual-12V rail PSU be suitable for my current aging Socket A system, im quoting something i read on the AT PSU thread:

"Socket A board without a 2x2 12V connector:
Do not use a dual 12V rail power supply. One of the two rails on a dual 12V rail power supply is for the 2x2 connector, so your power supply will have a rail you're not even capable of using!
Do not get a power supply with a higher amperage on the 12V rail than on the 5V rail. I know future-proofing is a usually a good thing to do, but typically when a power supply with a high 12V capability is hit with a heavy 5V load, even when it's within spec, there's a thing called "crossloading" that happens. Essentially, your 5V dips below tolerance and your 12V shoots above. Side effects include lock up or even system shut downs due to over or under volt protection!"

I think this is what is happening with my L&C 400W, rated 28/30/20. On load, the 12V shoots up to 13V and I get weird reboots/crashes. Will the same problem exist with the Delta Chieftec?

Never having owned or worked with a Socket A, I can just give a strong opinion.

What you have stated is true. Stick with a single 12V rail and the 5V amperage should
exceed the 12V amperage. However, some Socket A boards feed the CPU from the 12V rail,
most feed the CPU from the 5V rail. iirc.

Crossloading problems can be eliminated by loading the lightly used rail by 1~2 amps.
This can be done with an inexpensive ceramic, wire wound, ballast resistor. They cost
$0.49 here in The States.

Bump!

What more are you looking for, from this thread? Everything that Galvanized has told you is correct. I personally have alot of experience with Athlon XP's, and many, many processors before it, along with their psu's, so I can answer some of your questions.

For instance, here's how to find out who made your psu: link. Since your motherboard isn't one of the newer generation of Socket A motherboards, it powers the cpu from the 5v rail, instead of from the 12v rail.

That means that you need to find a power supply with at least 35 amps on the 5v rail. The 12v rail doesn't need to be strong at all, since it will only be powering your drives and fans; 10-12A should be plenty, unless you have alot of drives (though 15-18A is more common).
