Re: Wanna see a power supply with GOOD Fujhyyu caps??

Well, K-Lite came with mpc-hc and that didn't quite work out, so for now VLC will be fine. However, i've never had any trouble with k-lite, that is, until now... Will try to reinstall it and see how it goes. Btw, i tried a 720p mkv in VLC and it works fine.

Re: Wanna see a power supply with GOOD Fujhyyu caps??

Try CCCP and WMP or MPCHC, VLC is much more CPU demanding than the other on my laptop. The result is lagging video in VLC compared with smooth play in the other two. Probably due to it's own codecks.

Old ATX Fortrons also had these extra AT cables. Anyway, if it's running fine from two different PSU's, you could even take two somewhat decent PSU's (again Fortron, these are very common here in Czech Republic so I expect similar situation in Romania) and somehow solder the two 20pin connectors together into one, e.g. using the 20pin extend cable.

Two Fortrons? Yeah that could be doable. I will however try to get by with a single PSU. On the 7th i go back home, it shouldn't take me more than 3-4 days to build and test the booster PSU. I have decided on using my 555-based controller, the protection will simply be a crowbar circuit which shorts the output if voltage reaches 5.30v. Since i will be generating 5v from 12v, the current draw at short circuit should be enough to trigger short circuit protection of the Xilence PSU without blowing up the switching transistors of the booster PSU. I will be using 3 motherboard mosfets in parallel. Each of them is rated for 60A, so 3 of them shouldn't even need much heatsinking to switch ~10A. The output will be rectified by a SBL3040 since i have one around anyway.

But nice OC, really. I personally have to voltmod my TUSL2-C, it's not stable during sommer and I am actually on maximum voltage in BIOS now. Are you able to play Full HD now? I have no problems playing 1920i on Pentium M 1,8 GHz so you should be able, too.

I'll try HD content now. I had trouble playing XviD because the K-Lite Codec Pack did not install properly this time (no idea why), but i installed VLC and now everything is as smooth as possible, and a regular DVD rip movie doesn't take up more than 10-15% CPU.

Such a machine would be nice for one casemod I have in plan, it'll also probably solve the problem with Full HD playback cause I did not succeed with OCing Athlon XP on A7N8X-E Deluxe due to memory instability. Now it's still not enough to play it without lags...

Re: Wanna see a power supply with GOOD Fujhyyu caps??

Here the pix: http://img828.*************/g/dsc00753v.jpg/ As you can see, very very good transient filtering stage.. NOT, 4 diode treatment (don't care about that however, Europe is 230 volts), and Fuhjyyu caps. Works just fine however...

Since you are taping +12v which is already filtered I'd think a simple one chip LDO +5v VR with a low ESR cap on OP would be fine.

A linear regulator? I think that'd be close to impossible.

If you're going to mod the PSU, wouldn't it be easier to just install a second schottky diode on the 5v rail (if the PSU has a spot for it on the PCB, of course)? Two SBL3040's in parallel would theoretically give you 60A capacity. With decent heatsinks they should deliver 30A no problem (150W). Every once in a while, you may find a SBL3040 on the 5v rail in those "chinese firecracker" PSUs .

It isn't the diodes, it's the transformer. The Xilence isn't a gutless wonder, my problems are due to crossloading ie no load on the 12v rail.

How low does it go? If it's not under 4.75v, then it's still in spec. Use your multimeter to check and not the onboard monitors because those are inaccurate most of the time. Perhaps excessive ripple on the 5v rail may be causing your issue (I had a Maxtor hard drive not spin up due to bad caps on the 3.3v/5v rails. The other hard drive in that computer spun up fine).

REALLY low. Think 4.49v measured.

Also, weren't those PIII Tualatins something like 30 Watt TDP each? If so, that's 60W for the CPUs alone, which isn't a whole lot really. Still better than most signle core P4 . Perhaps with the video card and everything else, you may be pulling ~150W on the 3.3v/5v at max load.

Yes, but a P4 uses 12v as its power supply... Anyway, update. After doing the VID mod (which i will post pictures of shortly), the system became even more unstable. Reason? The already low 5v rail fell under 4.5v... However the kind guys at Asus left me an extra power connector on the board, with one 5v rail, two 3.3 and three grounds, which happened to accept an AT cable... I had one in my junk box, so i wired it to my secondary PSU (yes, the one with the Fuhjyyus), plugged it in and hoped for the best.

And what do you know, perfect stability at 146FSB, which is 1.53GHz. Awesomeness.

Re: Wanna see a power supply with GOOD Fujhyyu caps??

I'm experienced enough to build a buck converter that supplements the 5v rail with power from 12v, besides, i got lots of motherboard mosfets around, and some synchronous buck converter controllers (like the ones that regulate CPU voltages) as well. I think i can use those for 5v

The PSU with the Fuhhjyus i use to power my hard drive since i got this new motherboard because with the CPUs both running at their rated frequency and voltage, the 5v rail goes so low that my hard drive spins down.

Th3_uN1Qu3; I second Behemot's sugestion
Use the European eBay sites instead, like .co.uk or .de
And search for items in the European Union
You will then not have to pay any import tax since the item is bought within EU's borders...

Re: Wanna see a power supply with GOOD Fujhyyu caps??

You can buy something on eBay in Germany (or Poland, Austria, Belgium), I'd say most people won't have problem with sending any goods to other EU coutries.

e.g. Enermax EG301AX there are several of this.

Re: Wanna see a power supply with GOOD Fujhyyu caps??

You need to read up on what the various versions of ATX specs mean then look for the correct PSU for a 5v heavy system.
It's not that hard when you look for the right spec PSU.
.

Try finding one in Romania. I have to work with what i have available (okay, the Tualatins and various other P3-related stuff i got from the US, but shipping was a nightmare), so i'd rather not go thru that again. It's hard to find a power supply that adheres to the old 5v-heavy standard except the chinese firecrackers.

I found some Super Flower PSUs here but none of what you mentioned unfortunately.

I think i can use those for 5v. If not, my custom 555-based controller will probably be called to the rescue again, but it needs to be updated with some protections. In any case, i still have to get home to use my scope.

Re: Wanna see a power supply with GOOD Fujhyyu caps??

The 5v rail on the Xilence is rated for 27A, it's hard to find a PSU with more than 30A on 5v, so not many options here.

Super Flower-two fans:
SF-400P02: 38 A
SF-430 A02: 40 A
SF-480 A02: 42 A
SF-530 A02: 48 A
Super Flower-one fan:
SF-400P01: 38 A

They also have much better build quality than Xilence.

If you look at similar PSU's of the same age (Enermax, Chieftec, Thermaltake), you'll find they have also more than 30 A@5 V and sometimes close to 40 A, too.

Re: Wanna see a power supply with GOOD Fujhyyu caps??

Because i can't find one suitable for this computer. In my main C2D rig i have a Seasonic SS-500HT, i don't run junk PSUs unless i have a good reason to.

The main PSU of this dual-PIII is a Xilence 420W so that's decent enough as well. However, due to severe crossloading the 5v rail sags and there's nothing i can do about it right now. The PSU with the Fuhhjyus i use to power my hard drive since i got this new motherboard because with the CPUs both running at their rated frequency and voltage, the 5v rail goes so low that my hard drive spins down. The 5v rail on the Xilence is rated for 27A, it's hard to find a PSU with more than 30A on 5v, so not many options here.

Most of my testing equipment, including my scope, is at home, so i can't really do much right now. When i get back home i will build a buck converter that will take power from the 12v rail and pump it into the 5v rail, so that i won't need this secondary PSU anymore. But until then this is the only solution. I could use some resistors to load up the 12v rail so that 5v goes up, but it's hot enough in here as it is.

Re: Wanna see a power supply with GOOD Fujhyyu caps??

Blasphemy!
Referring to the "F" brand and mentioning "good" in the same sentence should be grounds for banning on this forum

Anyway, just as Rubycon may once every millionth batch they manufacture make a dud, likewise the F brand may actually manage to make a good batch which does not fail catastrophically in 3 months every millionth batch or so...

Oh, and just because it is not bulging doe not mean it can not have failed already, you realize that aswell right?

Re: Wanna see a power supply with GOOD Fujhyyu caps??

That ATNG I posted has 250W combined on the 5v and 3.3v rail. Just the other day there was anther one on ebay from the same seller I bought it from for $8.20. It either ended or someone snatched it up as I can't find it now. The only thing about that power supply is you would need to do a recap to it. Also the fan runs at a constant 12v.

Re: Wanna see a power supply with GOOD Fujhyyu caps??

Oh dual I see it now I want such a system one day, but I'll probably start with old dual Pentium Pro or something...oh yees...

Better grab one while they still exist. I have a high-end C2D system at home and two midrange gaming laptops, but this computer i have here at my grandparents' place is the system that impressed me the most. In 4 years, ZERO crashes or BSODs. The Windows install held thru countless component changes. So imagine my frustration when the HDD went awry yesterday due to not enough power... Oh well, radical mods coming up and will be posted here among other places.

A little birdie told me that there exists such an animal as a dual socket 370 board with DDR memory slots. If you find one of those, my hat goes off to you.

I'll post pics of that power supply in about an hour.

Re: Wanna see a power supply with GOOD Fujhyyu caps??

my thought exactly. it will blow up, it hasn't yet, but it will. and when it does, it might take the rest of the system with it to computer heaven... 18v on the 5vsb is not good...

A hard drive don't need no 5vsb.

@ Behemot: Dual 1.4GHz PIII-S (not Celeron, the real deal with 512kB cache), see, i said dual. Two CPUs eat more power than one... Asus CUV4X-DLS, 4x 256MB SDRAM from my old BX board but now i can use up to 4x 1GB (!!!), voltmodded Radeon 9800 Pro 256MB, Silicon Image Sil3112 PCI SATA card + Western Digital 320GB, VIA 4-port USB 2.0 card, Lite-on DVD writer. A4Tech wireless kb/mouse, and a huge ass CRT - IBM P275. Also all my fans are running off 5v or 7v, so that plays a role as well. The only component actually using the 12v rail is the video card with its extra power connector, but that does nothing when i'm not gaming.

As the CUV4X-DLS mobo i just got on Friday has an AGP4x slot i will be getting a HD4670 1GB AGP. Grand Theft Auto IV on a Pentium III, can you believe it?

[Behemot]

Re: Wanna see a power supply with GOOD Fujhyyu caps??

Well, long story short (this is something for a later occasion), i needed a secondary PSU to run the SATA HDD in a dual PIII Tualatin system that is *extremely* 5 volt heavy. So heavy, that after buying a mobo that would run the CPUs at their full 1.4GHz, there was not enough 5v juice left to run the hard drive anymore!

Interesting. What are the specs? I made system with Celeron 1,1@1,46 GHz Tualatin (voltage on max, voltmod planned for future) and FX 5200 for older games, it runs just fine on 300W Fortron.
