I get it now,.. even though my computers
don't require that much wattage the only
decent PSU are in the 600W and up range.

Question; even if I open up both the 8500 and 780
computers to get the PSU measurements,I don't see
any online measurements for the PSU?

So how do I know if they'll fit? Also how do I verify
cable length online other than comments?

Robert


I've been trying to place the "standard dimensions", where
the faceplace of the supply fits your PC, into the first
two dimensions. The third dimension is the length. Modular
supplied, where the cables unplug, add a slight bit of length
to the supply. 6.3" is 160mm. You can check your PC
for the length of the current supply and compare.

SeaSonic SS-650KM ATX12V 80PLUS GOLD $91
(+3.3V@25A, +5V@25A, 125W) +12V@54A, ,
??? Modular, no pictures
3.40" x 5.90" x 6.30"

https://www.newegg.com/Product/Produ...82E16817151088

To see the cables, I find a review.

http://www.jonnyguru.com/modules.php...Story&reid=169

Modular, Fully sleeved, colored wires (can't see if coloring is correct)

Modular Cables (each "length" is position of connector, the long portion
being the part next to the power supply. Three measured
numbers represents three connector details. The floppy power
is an "extender" you plug into another cable.)

ATX connector (560mm) 20+4 pin
4 pin ATX12V connector (570mm) 1
8 pin EPS12V connector (570mm) 2
SATA (350mm+150mm) 2
SATA (440mm+150mm+150mm) 3
SATA (540mm+150mm+150mm) 3
5.25" Drive (350mm+150mm) 2
5.25" Drive (440mm+150mm+150mm) 3
5.25" Drive (540mm+150mm+150mm) 3
3.5" Drive (150mm 5.25-3.5" adaptor) 2
6+2 PCIe (580mm) 4

You'll never feel any heat come out of that.
90% efficient.

It does have good reviews.

I'll take the measurements of
the 8500 and 780 PSU,'s tomorrow
with screenshots.

There was one "bottom dweller" I trusted, because
I bought one :-) The inrush was a little high (makes
the lights dim for a fraction of a second), but the
customer reviews had hardly any failures listed.

And at one time, I would buy HEC supplies (Heroichi???).
Which were old-fashioned or traditional designs,
and I never had one of those blow up.

But if you read the Newegg customer comments for some
of them, you begin to wonder if they're a good deal.
Even if only 3% of people write in and give their
"bad" story, maybe that's too much.

I was surprised on one of the questionable brands
I was looking at yesterday, to see a report of "flame"
from the thing. It's been a long time since someone
reported something like that. I've had one smoke
(an Antec CMT one), but that's about as exciting
as it gets here. The smoke would come from
dried-out +5V electrolytics on the output side.
just as the power came on. After they "warmed up"
a bit, the smoke would stop. Eventually, the PC crashed.

And one other thing you look for, is PSUs that damage
other computer components when they fail. One famous
Bestec model, used to put something like +9V on the
+5V rail, and the only thing you got to keep after
that happened, was the RAM DIMMs and the CPU itself.
Everything else was ruined.

Many modern ATX supplies have protections that result
in fewer ruined components. That's why your $90 supply
has a list of those:

Protection: OPP, Output Power Protection (thermistor based???)
OVP, Over voltage protection (prevent +9V on +5V rail)
UVP, Under voltage protection
OCP, Over current protection (maybe 25A per loom)
OTP, Over Temperature
SCP Short Circuit Protection (maybe 54A total measured inside)

Some of those overlap a bit. The OVP is pretty important,
The UVP not so much (except in cases where voltage
sequencing is assumed). That's why UVP is not specified
in the spec.

A google shows you can learn more here.

I did see some of the bad reviews and had
the same thought but I put that against
the entire reviews and it didn't seem so
bad but taken your comments into account
maybe there is something to it?

It does seem to be a good one though.

I've bought some of my supplies during clearance
sales. One brand no longer wanted to do warranty
repairs here, and decided to get out of our market
entirely. And I got a couple supplies while those
were being cleared out. They were a good brand,
so I wasn't particular worried.

Those are the supplies that run my main machines today.

I don't know what the tariffs in 2019 will do to
the price of these things. As otherwise, there should
only be the normal seasonal variation in price.

Hmmm I thought I had Windows Denfender but it's not listed in Programs and Features. and come it think of it , it hasn't come on for a scan in a long
time now? I can't remember if this was manual or not? I do all the other scans and updates.

Well that's weird how it grayed my message

I also wanted to ask you while I was updating
Spywareblaster it has an option similar to making
a restore point. Should I go ahead and do that
as another precaution?

Thanks,

5 3/8 and 5 1/2 might be similar to the
products which are 140mm long (5.51").

3.39" x 5.91" x 5.51"

+----------+ | === cable loom drapes down,
|- LEN --| and you want sufficient

of the DVD drive on the right

Your existing PSU could be a 140mm one.

The one you've selected:

https://www.newegg.com/Product/Produ...82E16817151088

is 6.3" long or 160mm.

That's 20mm or 0.8" longer than before.

The modular cables, the connector body where
it meets the ATX PSU casing, that part doesn't
bend, so the loom sticks back a bit further
than a PSU with a captive cable and a grommet
where the cable bundle leaves the ATX.

I don't think it makes any difference, unless you
can see already it's quite tight with no maneuvering
room at all. It could be 1.25" closer to the DVD drive
connectors than before. At a guess.

If it's modular, you don't have to plug all the cables
in. That's good.

But the cables that do have to be plugged in, they need
to be "folded up" a bit, to take up the slack. In my
current system, this folding deal is quite a nuisance.
The last work I did in the PC, I had to rearrange that
rats nest again, use some cable ties and so on, to
get some finger room to do stuff there. Even with
modular, it doesn't solve all problems.

Some people have custom modular cables made up, or they get
a crimping tool and pins, and shorten the cables to
give a custom fit. You can do that with the old
Molex, but the SATA ones are not amenable to that
sort of thing. (There might be a tool to install
those, but the modern SATA fitting method and
the power ribbon cables, I don't know if I'd want to
try that myself. Don't want a smokefest if
something shorts out.)

My builds don't win beauty contests - I just make
sure everything fits in the case, no fan blades
got jammed, and I'm done. I don't "hide" the cables
behind the motherboard tray or anything. I *never* buy
cases with transparent side covers. Most of the
space in my PCs is taken up by heatsinks.

The Spywareblaster could be making a real restore
point (System Restore). This implies it is installing
newer code for some reason.

Restore points have a copy of the Registry, and
they also capture the state before a program
installation was done. In an emergency, you can
enter Safe Mode and restore to the previous point in
time using that Restore Point.

Now, if this is a restore point internal to Spywareblaster,
I wouldn't know a thing about that. I don't use
that product.

These of course are backups PSU's so I'll just
check the contents of the packages to verify
I have everything.

So it'll fit although close, but as you
say I'll just fold and zip tie the cables
and keep it as clean as possible and away
from the fans.


Thanks,
Robert

How _you_ see it in "G2/1.0" (Google Groups I think), doesn't affect how
the rest of us do - I see all new text in black, but some here may see
it in purple on puce with a Gothic typeface ... (-:

I was thinking about the size of the $91 Seasonic X
,. so I looked further and found this. It says it's
compact, 125 MM.

What do you think?
