[DEAD] LiteOn 300W PSU $19 @ Directron

[mindless1]

I found those 240W Deltas at Centrix Int'l about 18 months ago. They started out at $14, then $7 each Naturally I bought a dozen of 'em but should've bought more. I keep checking there, hoping for anywhere near as good a deal, but it must've been a one-time event, they haven't carried them since then AFAIK.

I don't know if they're the same exact PSU as those in the Andara system or not... these were ATX12V but very distinctive because they had the entire primary (AC) side mounted on a fairly large second circuit board that was upside down, it's backside visible through the perf'd air intake on the bottom... nothing at all like the 250W Deltas I've pulled out of some Compaq systems.

I bought two a couple of months ago, when the price was $15.00. Both tested good at the time and both are now working in systems (2nd one installed just this afternoon.) I am ordering 2 more for stock.

Be sure to check out the CLEARANCE section for super deals to fill out your order. Mice, cheap as $1. Keyboards, cheap as $2. Case fans, cheap as 40 cents, etc. Look for the NEW|SPECIALS links on the home page, then choose CLEARANCE.

Shipping is not free but is reasonable.

How's the noise level?

<~~ Didn't read through the whole thread.

noise level's tolerable

Is the pcb of the lite-on supposed to face downwards, with the heatsink facing upwards (in relation to being in the computer case)?

I ask because on my case, the screw holes are placed so that the psu's pcb goes up, with the heatsink down, and i think that would kinda defeat the purpose to disappate heat.

 

[mindless1]

It doesn't matter which way you orient this power supply so long as the case accomodates the fan exhaust and you can screw it down. The fan moves enough air that the effect of hot air rising is null, since that air is removed. Most power supplies do have the PCB "upside down", even when they don't have holes on the underside, as with this Liteon.

 

[djkym]

in the long run, do you think having that pcb faced up would make it last less longer?

i ask because i just blew a psu and i was wondering about what i could do to build the most stable system possible.

thanks!

 

[mindless1]

Nope, I think it makes no difference.

This power supply is designed to last a long time, but it isn't "bulletproof"... Primarily you need take the same care as with any other PSU, provide enough case ventilation that it can move adequate amounts of air through it, clean it out every couple years (or whatever appropriate interval) if it's in a dusty environment, and of course put it behind a surge protector (or in locations with very hostile electric lines, a line conditioner).

Oh yeah, I almost forgot... don't leave your window open above the desk so rain can come in, run across the desk till it reaches the monitor cord, run down the monitor cord into the case through the video card slot and down the AC cord into the surge protector. LOL.

The failure mode of your last PSU would have to be analyzed to determine if there's anything else applicable to your particular use/needs.

Overdue for a bump.

The deal is still good and hot. $18.99 + fair shipping for a high quality power supply with strong 3.3 and 5v lines.
Buy 2 for 36.00, or 10 for 170.00.

Or buy it HERE, for $252.00, as a Compaq Proliant server spare part.

The one I put in my mother-in-law's machine in December is still working fine. Excellent PSU.

 

[camlopey]

Does look like a great deal.
Would this be a good replacement for my PC Power & Cooling Silencer 275? Or am I better off Staying with PC P&C?

Like some others have said here, the +12v looks a little weak. The generic 300w "enhance" power supply I have now has 1a more than this one does on the +12v line.

According to the last power supply review article I read, the +12v line is the most important. Or are they wrong?

Scattered throughout this thread are details of the limitations of this PSU, but to sum it up:

Not appropriate for a P4 or Athlon using 12V for CPU (would have the ATX12V 4-pin connector if it uses 12V for CPU). At least two popular websites have articles clearly in err, implying that all Athlons run off of 12V rail when many use 5V... consider YOUR particular motherboard. It "might" work powering such a "12V CPu" if the system had minimal number of HDD, but it's not the right PSU for such a system.

Not appropriate for powering a peltier along with the whole system.

Not appropriate for a half dozen or more HDD. It actually may work fine powering 6 HDD, I had 5 on mine plus 12 fans, but inevitably if you start making claims about hard drives, soon enough someone will come along and ask "will it run two more?"... if you have that much $ and time/data tied up in HDD then spend $100 for a nice 500W name-brand PSU.

All capacities on this power supply are rated for continuous use, not surge... unlike cheap PSU, it should run at full rated load 24/7, for it's full MTBF. Many PSU can only support brief surges at their rated capacity on all rails, "might" be able to supply 70% of that for their MTBF. I have other PSU that are rated as 15A on their 12V rail (like Antec) that are not designed to better accomodate higher 12V loads than this Liteon, but since all PSU aren't rated the same, simply comparing Amperage rating on the label isn't very telling.

The PSU has good voltage regulation, if you did try to overload it, should shut down gracefully instead of exploding. If you try to explode it, you're asking for trouble though... a creative mind can find ways to destroy stuff. Uhhh, make that "destructive mind".

This LiteOn 300W PSU works great. I have the following:

Abit KT7 RAID mobo
XP2100+ CPU @ 1.74V
1 CDRW, 1 DVD+RW, 1 DVD ROM
4 IDE HDs, 1 SCSI 15k rpm HD (Seagate Cheetah 15k.3)
total 3 slabs of PC133 SDRAM (2 slabs 256MB, 1 slab 128MB)
GF4 Ti4200 AGP8x 128MB
Audigy2 platinum
3com 3C905B NIC
Hauppauge WinTV tuner card
LSI SCSI HBA
4 Panaflo L1A's

Even for such a loaded system, the +12V rail is at 11.77V (well within 2% of 12V), +5V and +3.33 V are exactly at spec.

Overall, a steal for $19.

Looks like the end of this deal.
