Power supply

K

Ken

I want to build a PC the function of which is only for storage at home.
I want to purchase a reliable power supply but I don't really know
what that means. Over the past 20 years, only one power supply has died
out of perhaps as many laptop and desktops combined.

I already have 4 drives that total about 1.1 terabytes. I will have a
3mHz cpu, no sound, no high-end video, and only a CD-Rom in the system.
I think that 450 watts should allow the system to pull without problems.

What advice does anyone have for me?

Thanks

400W should do it. Look for fortron/sparkle or Seasonic. In fact, a 380W
Seasonic should work fine. -Dave

Could be OK but to be on the safe side I'd check the HDD manufactures
specification. The maximum 12VDC start up current is always listed. The sum
of these should be about the capacity of the power supply.

Would that allow for another drive or two?

Yes. The drives only pull significant current when they are spinning up.
It is unlikely you'd have more than 2 spinning up at once, so add as many as
you want. 380W should still do it. The catch is, don't cheap out on the
power supply. A 500W Deer for example, would choke on that system. -Dave

Buy a brand name supply, not the cheap and nasty generics, especially if
you want to have some margin of upgradability. Power supplies differ
greatly on how much they will actually put out on the 12V rail, and the
cheaper ones tend to be poorer for that. As with most things, you get
what you pay for. I use Antec in my systems, a budget brand name.

Regards,

Ari

I'm going to die rather sooner than I'd like. I tried to protect my
neighbours from crime, and became the victim of it. Complications in
hospital following this resulted in a serious illness. I now need a bone
marrow transplant. Many people around the world are waiting for a marrow
transplant, too. Please volunteer to be a marrow donor:

Like Deer, Powmax, Achieve, or Codegen?

I know you don't mean any of those, but there's really
no such thing as a generic supply because everything
sold, no matter how bad or how cheap, has a brand
name attached to it.

You need the brand new Antec 450 watt power supply I have for sale on Ebay
right now! ;-P

But seriously, I run Seasonics and Antecs and think they are great. Seasonic
when it's got to be good (my machine). Antec when it's got to be cheap, but
dependable (father-in-laws machine). 400 to 500 watt will run almost
anything but the most ridiculously tricked out boxes.

Reliability is going to be high on the list, as it will be powering a
large amount of storage. I have used Antec in the past with good
success. My question, I suppose, is whether it is worth spending the
money on a supply like PC Power and Cooling or whether there are some
reliable brands for less. If so, what are the brands I should look at?

Other equally good brands include Delta, Lite-on, Etasis, Astec,
NMB-Mineba, Zippy-Emacs, Win-tact, Seasonic, and Fortron-Source. In
the US, only Seasonic and Fortron are easy to find on the retail
market. Fortron is unbelievably cheap and is sold under several
brands, including Fortron, Sparkle, Hi-Q, PowerQ, Powertech, and Trend
-- look for model numbers starting with FSP.

Almost as good are Enermax (AKA Wavesonic, Cooler Giant, Casemart),
Channel Well Technology A-series or B-series (sold most commonly as
Antec TruePower and SmartPower).

If a PSU isn't strained by the load, about the only things that will
make it fail are excessive heat (fan stops) and bad capacitors.
Apparently electrolytic capacitors vary greatly in quality, with some
Taiwan and Chinese brands being terrible and Japanese brands being
among the best. I believe that Seasonic, Delta, and Lite-on use only
Japanese capacitors. Channel Well uses Taiwan Fuhjyyu, which were
affected by the counterfeit electrolyte scandal of a few years ago.
Enermax seems to use lots of PC-Tur, a Taiwan brand that apparently is
reliable (another is Taicon, affiliated with a Japanese capacitor
maker) and never affected by the scandal. In Fortron-Source I've seen
lots of Taiwan Teapo, also found in PCP&C PSUs.

Few websites do legitimate PSU reviews, that is, reviews where the PSUs
are made to put out at least their maximum watt and amp ratings. Some
of the rare exceptions are:

Decent PSU reviews are rare. Almost all are at:

www.jonnyguru.com
www.slcentral.com (done by Jonny Guru)
www.hexus.net
www.silentpcreview.com
www.tomshardware.com
www.xbit-labs.com

Disregard reviews that don't load down the test units to at least 100%
full power, i.e. each unit's rated maximum power, rather than simply
use a computer as the load. Also disregard trivial voltage accuracy
ratings because it doesn't matter that one PSU maintains voltages
within 0.5% while another deviates 3-4%.

You don't need to spend big $$$ on PCP&C to get top quality. Other
great manufacturers include Zippy-Emacs, Win-tact, Etasis,
Fortron-Source (Hi-Q, PowerQ, Powertech, Trend, Sparkle -- look for
model number starting with "FSP"), Seasonic, Lite-On, NMB/Mineba, and
Delta. Of these, about the only ones readily available at the retail
level in the U.S. are Seasonic and Fortron, and Fortron is an
unbelievably low-cost bargain.

Also very good are Channel Well Technology A- and B-series (identical
to Antec TruePower and SmartPower), Enermax/Wavesonic/Casemart/Cooler
Giant,

If you want something that will last forever, look for one of those
brands with Japanese brand capacitors inside, some being Delta,
Seasonic, and Lite-On. Enermax uses lots of Taiwanese PC-Tur brand
caps, but I haven't heard of this brand having problems with premature
failure, and apparently they avoided the counterfeit electrolyte
scandal of a few years ago. PCP&C uses lots of Teapo caps, and I don't
know how good they are, but apparently they were never among the worst.
Antec uses lots of Fuhjyyu, except for their NeoHE series (produced by
Seasonic rather than Channel Well), which did use bad electrolyte.

PCP&C are worth every penny and I have been using them since they have made
there way to the market and I have never had one fail. You get what you pay
for when it comes to a top quality power supply and it is the heart of or
system.

Yes, 380W Seasonic is an excellent choice. Another advantage to
Seasonic is that it is more efficient that almost all the other power
supplies out there. That means a cooler running power supply and real
savings on electricity. The latter being especially important for a
server that is on 24/7.

Not even batteries?
You get what you pay for when it comes to a top quality power supply

And at the heart of PCP&C power supplies are Teapo capacitors, not the
best brand.. For what they charge I'd expect Rubycon, Nichicon, Sanyo,
or Chemicon capacitors, which are found in lower cost Seasonic and
Delta supplies.
