[DEAD] LiteOn 300W PSU $19 @ Directron

[mindless1]

My LiteOn PSU was delivered a couple days ago, is exactly like the last one i bought from Directron, no complaints at all except that whoever packed my package left several heatsinks loose in the box, causing a few scratches in transit. Scratches and all, it's still a great deal IMHO.

I got mine, I am impressed,
I made a little comparison page of this Lite-On and and Antec True-Power 330watt PS. Also this is actually a 400watt PS that has been conservatively rated at 300watts.

That Lite-on PS looks pretty raggedy. I know these are OEM, but are they really THAT OEM?

The Lite-on is built better than the Antec, oh yes the Antec is an overrated pile of cow dung IMO. I throwing mine in the dumpster and replacing it with another Lite-On.

Sounds good, I am going to try them.....

 

[BentValve]

Hey I found another one that is priced even better.......
Compaq PN- 148789-001 (exact same PS)




Edit: also I found the server it originally went in, check my website link above.

Regular price: $346.00 Sale price: $289.00

Woohoo!
I've been telling people that my rig is running off a Compaq server power supply. Now I can boast of having a $300+ Compaq server power supply in my rig, for the low, low, price of $17 delivered (posted and got in on the 1st Directron deal for these, back in August). Now that is Hot!

FYI: Old LiteOn Deal Thread from August HERE.

That is one old server. Is that three ISA slots I see?

 

[Justin218]

I got in on that $13 delta PSU as well. It's been very good once I got it working. Had to put some resistors on the 3.3 volt line I think, or one fot he lines atleast.

 

[UCDznutz]

think i might have to get this. my k7s5a/2000+ combo has been randomly rebooting. think it might be an underpowered PSU (300W Antec with only about 160w rated for the 3v/5v)

?
looks like 1 ISA, pretty common for a P3 board

Whats the max Athlon Xp cpu you would use with this psu? So how do these handle overclocking the cpu?

Provided your motherboard doesn't use 12V (P4 connector) for the CPU power, you are not limited by the PSU to any maximum speed CPU. On the contrary, there are VERY few PSU which have a higher 5v rating.

The primary limitation of this PSU is it's 12V capacity. Realistically it's limited to 3-4 HDD plus typical compliment of optical drives and fans. In other words, you won't get a better PC PSU for more money, you'll just gain more 12V current, the ability to run more than 3 hard drives or a peltier, etc. With a different PSU you might also gain a fan underneath which could be pretty important in some mATX cases, and the other obvious advantage of the ability to power a P4 or Athlon board with the 4-pin 12V connector.

It will run any Athlon easily, it would even run a dual Athlon MP setup easily. Like Mindless1 said you might have a problem if the Athlon runs off the 12V rail....however I have yet to find a single Athlon Mobo on the planet that powers the CPU via the 12V rail.

This is one stiff puppy, I have loaded the hell out of it and cannot get it to fluxuate in any of rail by more than .03 V , considering .1 V is tolerable then that is low as heck.
I would give you some exact numbers but a friend of my is using my clamp on ampmeter right now.

Basically the only PC this PS is not suitable for is a P4 system since it does not have the 4 in connector.

 

[BalAtWork]

The abit NF7-S can use the theP4 12V power connector...I was wondering if someone could help me figure out if that connector is REQUIRED though for the board to operate?

Also, any ideas on a good power supply with the extra connector for the aditional 12V power?

Quiet is also good...

Thats right, I forgot that Mindless1 had mentioned that the newer Nforce2 mobos are using the 12V connector, in that case this PS is not the best choice.

There are alot of good PSU options for that mobo, although I have no idea which ones would be the most quiet.

 

[mindless1]

Most nForce boards, and a seemingly random sampling of other boards do use the 4 pin connector, but others don't. Newegg.com is a great place to see a picture of the motherboards and look for that 4 pin connector (would be near the mosfets).

If the motherboard uses the 4-pin 12V connector, this PSU "may" work but is not the best choice, and it would likely need a power plug to ATX12V 4-pin adapter. Once you add the cost of the adapter and consider the lower 12V rating it would seem better to use some other brand with a 350+W rating (since most PSU ratings over 300W coincide to an increase on 12V rail capacity).

I have a 8k7a Mobo, XP1700+@1595mhz(1.9v), 256crucial ddr at 145, Geforce2 GTS(200/400), Antec 300w pp303xp, 40gig ibm drive, 1 dvdrom, 1cdrw, sblive!value sound. I have pretty good cooling. I have had this setup for about 10 months so far. In the past month I have been getting a weird problem sometimes when I'm either playing games or using prime95. My screen starts to have weird fuzzy lines across it and something in my system make a low buzzing noise which last for 1-7secs. I noticed while using Prime in MBM5 monitor my CPU would be 43celsius and (+5.00) would go to 4.66-4.68v. I noticed by lowering my voltage from 1.9v to lowest voltage 1.8v that I seen the problem less frequently. Do you think it is something with the power supply? Would replacing my PSU with the liteon fix this?

 

[katka]

Good post, but I would use the spammotel when purchasing from these guys. I use two different e-mail account to prove theory. After I ordered from them I started receiving XXX e-mail. I an NOT saying not to order but just use a disposible address.

Agree. This power is made for server, which means quality & reliability. Some crappy PS's are rated 400W or even 450W even though they only put out less than 350W.

Dell 4550 2.4GHz model has a conservatively rated 250W PS in it.(I think it is more likely 350W)

Would replacing my PSU with the liteon fix this?

First off, are you sure the CPU needs 1.9V @ 1.6GHz ? IIRC the last few XP1600 AGOIA I had would do 1.67GHz @ 1.65-1.7V. Then again, IF your motherboard or PSU is inadequate you might find that the CPU does need set to higher voltage to remain stable.

The easiest way to troubleshoot this is to load the system, duplicating the low 5V rail situation, then take voltage readings with a multimeter on a PSU power plug (or motherboard connector for 3.3V reading). This will tell you if the PSU is folding back, dropping the voltage, or the motherboard is the limitation.

I would expect the "wierd fuzzy lines" to be the video card, usually overheating, o'c, but possibly a dropped voltage (check voltage first). Motherboard monitor could be used to compare to the meter reading, but is no substitute when checking the PSU output. The buzzing sound could be a few things... two that come to mind are a burst capacitor that has dried out, or more likely a voltage drop puts a fan into an RPM range where it resonates (usually with sleeve-bearing fans). IIRC those Antec PP303XP PSU have a sleeve bearing fan, it might be good to replace it with a ball-bearing fan now, before it fails (though this is not to suggest that the PSU fan is necessarily the one that "might" be making noise).

I have one of those Antec PP303XP (which, BTW, is different than a PP303X), and can confirm that it is not as good as this LiteOn in any respect, including 12V capacity (regardless of it's labeled capacity). The Antec isn't a "bad" PSU, but is more appropriately considered a decent value PSU for a P3 system. Here is a look 'under the hood' of that PSU.

If you confirmed that the Antec was dropping the voltage at the connector then this LiteOn would seem an ideal replacement, providing your system can remain cool enough with a PSU that doesn't have the bottom air intake (usually no problem with a rear case fan behind the CPU as per AMD recommendations).

 

[BentValve]

BTW if you get one of these don't be alarmed when you see a little spark when you plug it in, since there is not external power switch I am guessing it pulls momentarly moderate load when you first plug it in.

I hope they have alot of these because I want to grab one more but I cannot order until tomorrow.

It could definatly be a PS problem for him, the PP303XP is significantly more powerful than the PP303X
If it were me I would upgrade that power supply regardless of what I thought the problem was, if nothing else is a good
preventative measure.

 

[JoeFoster]

thanks for the feedback. I have no multimeter. I went and took out geforce 2 gts agp card and popped in a old S3Trio64 pci video card. Now when I run prime95 torture test my (+5.00) is at 4.71-4.73 and I do not get the wierd fuzzy lines I used to get after 5 secs of prime95. I guess it either the geforce 2 or the power supply.


I went ahead and purchased the liteon powersupply.

 

[tommyli]

I went ahead and ordered 2 of these powersupplies after being fed up woth my Enermax 365VE FC... The voltages were very inconstant, to the point where I knew it was going to crash when my +5V line went under 4.3V (happens often).

I don't consider my system very loaded, specs:

Athlon 1600xp @ 2100XP
Dr.Thermal VI77N HSF.
1x 40GB Maxtor Diamond Max Plus 45 7200rpm
1x Gf4MX440 64MB DDR
1X Adda 57cfm 80mm case fan
3x Sunon 80mm case fan
2 of 6 USB ports used.

I hope this is more stable. I'm fed up with BSOD's and loss of data due to constant crashes
