Power supply recommendations Wanted

Hi,
My power supply fan recently quit and it overheated and died.
Actually it was kind of weird, the system was on most of the time 24/7 for the last few years. We had a power outage the other day, so I unplugged the pc at the power supply, I noticed the power supply felt unusually warm by the fan. I didn't plug the pc back in till the next day and it was dead. I checked the power supply internal fuse and then had the output checked locally and there was no output and the fan wasn't turning freely. So most likely it was on it's way out.

The brand & model of the power supply is a Seventeam ST-301HR 350W

This is the case I have. http://www.chenbro.com.tw/usa/product/product_preview.php?pid=74

I am looking for a replacement power supply and want to upgrade to a P4 power supply that is backwards compatible for 20 pin connector boards as that is what I currently have, and since I plan to upgrade to P4 in the near future.

So far I haven't seen to many power supplies that have 20"+ connector wiring, most seem to be 12" & 14". If you look at the case I have you will see why I need 20" connector wiring.

After not finding a power supply today I thought it would be best to find a power supply forum. That has brought me here as the members of this forum have more knowledge about power supplies than I do.

I am looking for a 400-600w ATX P4 backwards compatible power supply that has 20"+ connector wiring and is reasonably priced. around $40-50. I need 6 HDD connectors on it with the rest of the P4 and normal connectors along with preferably 2 sata connectors. I have seen some supplies that have 2 separate 12v lines. Do they work on a regular motherboard? If so I think a dual 12v would be best if its available for what I want to spend.
also 2 ball barring fans would be preferred.

I would really appreciate your recommendations on which power supply would be the best buy for what I have to spend.

Thanks,
DataCom

My system currently has:
2 HDD
ATX ECS motherboard
1 cdrw
1cdrom
1 tape backup
1 floppy drive
8 case fans

will be upgrading to P4 Multithreading
adding a dvd burner
 
It's a bit old, thats why I am upgrading to P4 3.0 +
currently it's a:
MB: ECS K7S5A
CPU: Duron 650 overclocked to 950

Thanks,

Cheap, but Good Power Supplies! http://www.hardforum.com/showpost.php?p=1027898523&postcount=7

Pick one fron the "quote" area at the top, these are designed for older systems. ;)

My #1 recommendation is:
$68.00 & shipping [24-pin ATX, includes 20-pin adaptor]
VANTEC ION 2 VAN-460N ATX12V/ EPS12V 460W
Output +3.3V@28A; +5V@30A; -5V@0.5A; +12V@30A; -12V@0.8A; +5VSB@3.0A

because it can handle anything from P3's & Durron's to A64 & P4 SLI. ;)

Thanks for the help, I am looking in those now.

I just ran accross a Enermax EG465AX-VE FMA power supply 460 watts
for under $40.00. it was used for about a year.

Are these good PSU?
Does that sound like a fair price?

Thanks,
DataCom
 
That is an EXCELLENT power supply. Single rail and lots of juice on both the 5V and 12V so it's good for your old system AND a future upgrade.
 
Which is these is better?

Enermax
EG465P-VE

Enermax
EG465AX-VE FMA

whats the difference between the P and the AX?


Thanks,
DataCom
 
yes I prefer the 20+4 pin modular


does either of these of that?
is that what the P or AX means?

Enermax
EG465P-VE

Enermax
EG465AX-VE FMA

Thanks,
DataCom

update:

EG465P-VE is only a 20 pin

EG465AX-VE FMA still unknown
 
I have been looking for a power supply, trying to get the most for my money :)

anyhow I was looking at the 400w and up since I am upgrading to a P4

I found this and it appears to rather nice for a 350w. is 350w to small for a P4 3.0?

SPARKLE ATX-350PA ATX12V 350Watts Power Supply,24pin & 4pin, SATA ±10% of 115Vrms/57~ 63Hz, ±10% of 230Vrms/47~ 53Hz, manual selection - OEM

http://www.newegg.com/Product/Produ...C-Sm4rterDe4ls&ATT=Power+Supplies#DetailSpecs

has 12v dual rail supports P4 and is reasonably priced
it isn't listed with dual 12v but the pdf says it has them. http://www.sparklepower.com/pdf/ATX-350PA.pdf


any comments on this?
 
If it's dual rail, then that's a bad idea for your current Duron situation.

You'll only be using the 12V1 rail as the 12V2 rail is specifically for CPU... assuming your CPU is powered off of the 12V2, which all boards today are.. but yours is not.
 
well this is getting to be a pain. I've looked at over 50 psu and haven't found one that meets the specs below.
I'm still looking for a 400w + psu for around $50.
that has:
20 inch connector lines.
Dimension: W150 x H86 x D140 (mm).
Number of Connectors: 20+ 4 Pins Main Power. P4 +12V CPU. Aux Power. 2 Serial ATA. 6-8 HDD Power. 2 FDD Power. 2 Fans Monitor. prefer dual 12v rail if possible.

I just said; you don't want dual 12V rails for your Duron.

Why 20" cables? I have a recommendation if you can use 16". The ATX, SATA, 2x2 and PCIe are 16" and the drive Molexes are a good two feet long on an Ultra V-Series 400W. It's got a single 12V rail (20A), plenty on the 5V for your older system (30A), 2 SATA, PCI-e, 20+4 and a very quiet 120MM fan and sells for $39.99. No fan monitor connector, but I always thought those were pretty silly.

I am upgrading to a P4 3.0 in the near future, so I don't want to buy a psu based just on my current setup. I want a psu that will handle the upgrade along with what is currently running.

Which is next to impossible. The suggestion I made is good for a Pentium 4 too as long as you're not running SLI (it only has 20A on the 12V and one PCI-e connector.) Other than that, I think your expectations are a little unrealistic. Almost anything made these days is going to have dual 12V rails, or is going to be more expensive (like an OCZ Powerstream.. that would be PERFECT for you.) or it's going to be something "old school" and not have the 20+4 or SATA.

I need 20 inch cables based on the server case I have.

I see the case, but still don't see why you'd need a 20" ATX and 2x2 connector.

But I'll take your word for it. I guess I'd just have to see it in person.

You, sir, have "painted yourself in a corner." ;)

You've got a case that requires long cables, an unrealistically low budget and you're trying to buy a power supply for both modern and antiquated standards.

I'm sure your dream power supply is out there somewhere. :)

EDIT: Like I'm seeing a bunch of SPI/FSP power supplies that would be perfect for you, but they only have 15A on the 12V (like the FSP400) and that's just not that much. :(
 
isn't a Duron cpu 5v based? If so what difference does it make on the 12v rails?

I bought that case 5 years ago.
I bought that case for 2 reasons. It should handle all future upgrades, not saying it will.
however the psu wasn't designed for such as it couldn't possibly be.

the case is split in half and has the power supply on the rear bottom right side where the mb is on left side of the divider in the center of the case with openings in the divider at the top and bottom in the middle. so either opening I use, the bottom or top opening a 20" mb cable is needed to get to the mb. The top opening is best as it keeps the wiring away from the mb.

I understand what you are saying, my original question was if it was possible and if so which psu is available for 50.00.
 
Yes, the Duron in your board is 5V powered, so having a 12V2 that doesn't do anything isn't a big deal since it'd only be used for the CPU anyways... but such power supplies also have very little on the 5V rail. What I call "rob Peter to pay Paul."
