HEC 425W PSu specs

[Ned Flanders]

Given the constant talk about power supplies I thought I'd list the specification for the HEC 425W PSU I've just installed as the specs are not listed on their website

HEC 425VR-PT
425W Peak (350 normal - on PSU label)

On Box

+3.3V 35A
+5V 37A
+12V 17A
-5V 1A
-12V 1A
+5VSB 2A

On PSU

+3.3V 20A
+5V 33A
+12V 15A
-5V 1A
-12V 1A
+5VSB 2A

all +/- 5%

Specs on PSu label match specs on back for HEC-350LR-PT...

Voltages are better than when I was using a Starnet/VIP 350W power supply - most notibly my 3.3V which would frequently dip below +/- 6%.

8 Molex connectors
P4 + half AT server connector
Overvolt, overpower and short circuit protection
Has CPU fan connector lead.

I wouldn't be surprised if some other manufacturer rebadges it so hopefully this will be of use to someone

Can you test voltages with a multimeter ?

And most importantly can you overclock any further ?

Hmm...
I have a HEC350LD-T at home lying around... I'll take a look at it.
It's a fine PSU, good for overclocking... but it was just plain loud.

Haven't had a chance to try overclocking any further but I don't think the PSU is the limit. Currently running Tbird 1000 (AVIA) @ 1400 (140FSB) with Nanya CAS 2.0 DDR. The CPU was bought sold as seen (3 for £10) and has noticable scorching on the sticker underneath ... maybe I should change my name to Lazarus

I'm most worried about my SCSI RAID card crapping out and hosing my system

The main reason I changed the power supply was the 3.3V rail. Usually it was about 3.18V on boot and never reached 3.20V. MBM would give me alerts on a heavy Medal of Honor (sic) session or multiple 3DMark2001SE looping.

With 2 x10k rpm U2 SCSI drives (occassionally 3), Geforce 3Ti 200 (heavily overclocked), Santa Cruz Sound Card, LAN card, MegaRAID 200 SCSI RAID card, 2x CDROM + several cooling fans I reckon I need a good, powerful PSU

Found the PSU... my 350w matches the yours on the label. BTW, it is rebadged by Antec for their 350w model.

I have a HEC psu too. You can find them in newegg under COMPUCASE CORP....

Welcome to our Forums, Ned Flanders. Never thought I'd meet you in person!

If you paid for a "425" Watt PS, it's time to send it back. The specs on the PS are good, maybe a bit better than usual for a 350W PS.

But it sure looks like you may have paid for a 425W PS, but received a 350W PS.

An SPI Sparkle 350W is $42 at Newegg, atm. If you paid ~$75 for this "425W" PS, it's time to say "foul play!"
