350 watt p4 ready Raidmax power supply. $11.99 with $4.35 shipping! hot!!

[doinmybestatlast]

I've built systems with this PSU many times. My latest ECS K7S5A, XP 2000+, 512 DDR, 40x CD-RW Lite-on, 16X DVD lite-On, neon light, two case fans, etc.

Never a hitch. IMHO, the best low cost PSU to come around lately.

 

[Solema]

I think I might go for the Linkwood 400x PSU. I am running my K7S5A/1800+ with a generic 250w PSU I took from my work a while back and I need the power upgrade. Does anyone have a Linkwood 400w running in a K7S5A?

 

[Caveman2001]

I have seen the good deals on power supplies here often. Well, so called good deals anyway.

I'll point out 2 links that you can read or not read and decide for yourself if this power supply is indeed a good deal.

Buy a Power Supply by the Pound!

Tom's Hardware Informative Power Supply Take

Tom's Hardware suggests to stay away from anything 250W and under. Directron shows the heavier usually the better.

I agree with both.

 

[Nutzo]

These seem to be pretty decent so far.

I replace an old 250 watt (actually a high quality one I've been using for years) with one of these & I was able to overclock my old 750 mhz Slot A thunderbird higher.

The best I was able to do before was (103x9.5) 978 Mhz.

With this 350 watt supply, I was able to get it up to 1035 Mhz (109x9.5) stable in Prime 95. Power was still stable. I proabbly could have gone higher, but the CPU was running a bit warm at that speed.

An extra 57 Mhz, or about 6 %

The seal on mine Raidmax PSU's were also broken :/ Wonder what that actually means?

 

[usual_suspect]

These PSU's are light as a feather. The seals were broken on the two they sent me also. And they shipped them both in one box side by side with no padding between, just clanging against each other the whole way.

My first and last order from SVC I think.

 

[tazmania99]

Anyone got this PSU? I cannot see the back of the PSU in the picture. Is there a on/off switch in the back? I need a 350W PSU for my Dell 4500. But the case design of the Dell 4500 is suck. It doesn't leave a hole for the PSU switch. So if this PSU has a switch, it is no good for my Dell 4500. Can anyone tell me please?

 

[Spongo]

Taz,

I got my two power supplies yesterday, and yes, there is a power switch in the back. The seals on my power supplies were also broken. Crazy.

[Snuffaluffaguss]

My old dell used a different pin out on the power supply, I would be carefull because I don' think you can use a standard ATX powersupply on a dell

Looks like it is the best low cost way to go?

EDIT: looks like MysticMan1 beat me to it

Edit some more.
Just ordered 2 of the Linkworld 400's for $34.
Shipping for 2 came to $8.85, so 2 delivered total $42.85, or $21.43 each.

The two 400w supplies ordered on Thursday the 19th arrived today, Tuesday the 24th. Very fast for ground.
The supplies shipped are labled Green Tech LPK2-25 400w.
3.3v 28A, 5v 35A, 12v 15A, so actually 447 watts, which is better than advertised (5v increased from 30A to 35A).
And the warranty seals are NOT broke!
No switch.

These look like the same stickers as supplies that ship with those $30 delivered ATX w/400 cases listed elsewhere.
Except, model # with one of those case w/ PS states LPK2-30 400w.
Also, the case w/ps has P4 connections and 3 lead legs for 9 drives, where the $17 Linkworld has no P4, and 2 legs for 6 drives.
Last difference is $17 PS adds bottom vent as well as normal front vents.

EDIT: This $17 Linkworld 400w stuff is junk. AVOID!!!!
One of the supplies will not power up system. Fans spin, but not enough juice to get going.

Other power supply did power up system.
Had an old $25 Computer Geeks case with 250w supply in system.
Was running an Epox 8kta3Pro+ with XP1600+ at 150x10.5 or XP1900+ speed.
Worked fine with 250w, with 3.3v@3.52v, 5v@4.70, and 12v@12.72v. But didn't like low 5v@4.70v.
With the brand new 400w junk, I now get 3.3v@3.52, 5v@4.70v, but 12v dropped to 12.48v.
No improvement in 5v line, and worse than 2+ year old geeks 250w supply!

Will report back on how well RMA goes through.

Probably a refurb. IMO this is the only reasonable explanation.

Got Cowbell? Then you're a ding-a-ling playing pocket pool.

 

[zodder]

You guys made me open the package to see if the seal was broken on mine....................and it is. I guess as long as it works, who cares?

To those with a the K7S5A, I have a 250W CompUSA PSU running a 1.2 T-Bird @1.33 using SDRAM and it runs like a charm. Either I got a good board, or , IMHO, the picky PSU thing is overrated.

 

[KennyH]

Anyone else experienced problems with that Linkworld PSU?

 

[WetWilly]

I got one of these a few days ago and, to put it nicely, it's definitely not cut out for use with higher speed/overclocked Athlon XPs. I have a Enhance 300W running in my rig - MSI 745 Ultra, XP 1600+ running at 9.5x190MHz, couple of drives. Under load, the 5v rail drops to 4.7v when running a CPU burn program. Figured the Raidmax 350W was worth a shot for $15, so I got it, popped it in, loaded the CPU burn program. The 5v rail dropped to 4.1v just before the system got unstable. BTW the seal on mine was intact.

This is the second $15 P/S I've gotten that doesn't cut it. I also picked up a Turbolink 420W a little while back. That one drops the 5v rail to 4.5v under load.

High quality AMD or P3 power supply.

$15.99 + fair shipping: 3.3V 30A 5V 40A, 250 watt TCO (specs better than most 400 420 500 watt units).

More info in this Thread on Anandtech, for a high quality PSU.
Link to QUALITY power supply. I'm very pleased with this one.

Got one of those Liteons as well. Definitely better than the Raidmax. However I found that while the 5v rail was a bit better than the Enhance 300W, the 12v rail was a bit worse. Under load the 12v rail would drop to 11.5v with the Liteon. That's with 2 HDD, 1 DVD-ROM, 1 CD-RW, 3 Panaflo case fans and 1 CPU fan.

The 12v line basically runs the motors in an AMD rig, so you should have plenty of juice available. Fans use about 0.1 to 0.3 amps apiece. Each HD wants less than an amp from the 12v line.

Does your 12v line start out much higher than 11.5v under a light load, or is it around 11.5 under any load? If it is steady, but low, there are 3 trimmer pots inside the Lite-On which you could tinker with, at some risk of personal injury or death. I'd leave it alone if it all seems to work ok.

The Lite-On has me at 11.80v on the 12v line. 2-7200RPM 40G RAID + 80G 7200RPM + 3 80mm fans + 60mm on GeForce3 + CDRW in a K7S5A with Athlon 1600+ at 1900+ (150Mhz) and 2-256 PC133 sdrams. The 3.3 and 5v lines have the very stable and accurate voltages needed for a reliable system, and give it good overclocking capability.

Lite-On OC to 150Mhz FSB (1900XP) Motherboard Monitor, average & low & high voltage readings
idle: 3.28 (3.26L 3.28H), 5.04 (4.99L 5.04H), 11.80 (11.75L 11.81H)
Load: 3.26 (3.26L 3.28H), 5.02 (5.02L 5.04H), 11.82 (11.75L 11.88H)
+/- 0.02 volts from idle to full cpu load, just amazingly great!

Does your 12v line start out much higher than 11.5v under a light load, or is it around 11.5 under any load? If it is steady, but low, there are 3 trimmer pots inside the Lite-On which you could tinker with, at some risk of personal injury or death. I'd leave it alone if it all seems to work ok.

The 12v line starts out at around 11.9v and drops rapidly to ~11.5 under full load. I don't think I'll do the personal injury risk thing for a $15 P/S

As an aside, if I sum up the combined shipped costs of the "cheap" P/S I've tried in the last 2-3 months I think I've spent close to what an Antec TruPower 430 would cost with a coupon deal.

Yeah, best not to mess with it if it swings that much (if it were stable it might pay to adjust it upwards). Your list adds up to maybe 5 amps on that 12v line, so it shouldn't drop like that unless there is a very heavy 3.3v 5v load (or a problem). Both of my Lite-Ons deliver steady 11.8v, with an AMD @1900XP and more 12v devices too (RAID etc.).

I just got burned by another DOA Newegg refurb. A $15 Channel Well 420W PSU (245 TCO, lighter and weaker than the Lite-On 300W). $13.45 return shipping to RMA it...

$13.45 return shipping on a $15 DOA power supply? Ouch......... I'm kinda surprised that Newegg doesn't have a better return/exchange policy...

 

[mindless1]

Just a few random comments....

If these PSU are "light" weight, they simply can't deliver their rated wattage? True capacity depends largely on three factors, the size of the transformers, the ability to dissipate the heat (size of the heatsinks) and the filtering caps (as buffers)... There's more to it than that, but this is the easy rule of thumb.

For those of you adding and multiplying all the rail's figures to get a total... it doesn't work like that, any single rail "might" be able to deliver the rated capacity if the rating is accurate, and "maybe" the 12V at the same time, but otherwise these figures are not standardized across manufacturers, they server only as a rough guide to compare PSU from the SAME manufacturer.

As for those of you seeing low voltages on their motherboards, you can NOT rely on the motherboard's reported voltage, ESPECIALLY the 5V rail... More often than not, a low 5V rail is because the motherboard itself is inadequate, not the PSU... you could perhaps try to compensate for a weak motherboard by using a PSU that outputs "out of range", at a value significantly over 5.0V, but any PSU that does this by default (with no adjustments) should be considered defective, not a sign of a better PSU, and this will also slightly overvolt your HDD/etc, making them run even hotter. Put the CPU under a full load, check the 5V rail by motherboard report, then compare to the 5V rail reading with a meter on one of the power connectors. If the reading taken by the meter at the power connector is still above 4.8V while the motherboard reads significantly lower, replace the motherboard.

 

[Oakenfold]

Well the brother in law's K7S5A rig wouldn't deal with this PS.

Will make a good test PS though, can't beat it for that but don't plan on running your main rig on this thing.
The Antec 300 W PP switching series is more up to snuff than this guy.
