nice price, I will be putting together a video editing rig soon, that will have probably 10 scsi hard drives, so this may be my best option.

Googlegear.com has it for $9 more BEFORE shipping. Which doesn't make it as hot, but if your looking for this PS and don't want to deal with ETW, this is another option.

With 10 scsi drive you would be better off with something that can handle that much amperage draw on the 12 volt line- since most high performace drives can draw 2amps each. Thats 20amps for the drives if they were all running at once. You add the draw from a AMD or Intel chip thats another 8-9amps - then you have misc. draw from the motherboard and other devices. You would need at least 30amps

Then you get into the 3.3v line for AMD boxes and 5v line for other stuff. This Antec 550w is underpowered for your application.

ANTEC TruePower 550
5v=40a
3.3v=32a
12v=24a
All lines equal 530watts as stated on their website and with the high amp rating on the 3.3v and 5v it means the PSU is concentrating on those more and leaving less for the 12v

A better choice for your application is the Enermax EG651P 550w
5v=36a
3.3v=36a
12v=36a
+3.3V & +5V=200W  Leaving the 12v line upwards of 350w

or even the Enermax EG465P-VE FC 460w
5v=35a
3.3=35a
12=33a
+3.3V & +5V =200W Leaving 12vline upwards of 260w

Wow..

I have been considering picking something up from ETW for the last few days, but their reseller ratings are TERRIBLE.

As much as I need a good deal, I can't afford to be ripped off like that.

Most SCSI drives draw current from both the 5V and 12V rails. For example, for the Cheetah 15k.3, starting current is about 1A on the 5V rail and 1.5A on the 12V rail; operating current is about 1A on both rails.

Umm didn't he already say that most high performance drives can draw 2A each? 1A from each rail equals what 4A? No 2A is what it equals.

If I read him correctly, he's saying it draws 2A from the 12V rail.

1A from 5V rail + 1A from 12V rail is different than 2A from 12V rail. First of all, in the first case, you draw a total of 17W, whereas in the second case you draw 24W. Second, drawing less current from the 12V rail is desirable because the CPU these days also draws from the 12V rail.

=P i am bad at calculating these, so i wont' get into the discussion. However what i want to say is that this is a great price for 550W considering i got my True Blue 480 around this price shipped... well around 85 shipped from directon.com back then

If you are going to spend this much on a power supply you might as well go for the best.

http://www.pcpowerandcooling.com/products/power_supplies/index.htm


antec truepower 550 = 32/40/24
pcp&c 425 = 40/40/20

The 425watt is comparable to antecs 550 in specs, and pc power and cooling makes the absolute best quality psu's around without a doubt. Very solid and every last voltage can be finely adjusted. Only downside is the cost, but some of them are decently priced. The make power supplies up past 600 watts if you have the cash, but right after the 425 watt model (which is roughly $135) the numbers skyrocket.

I. Warranty Length
Parts and labor are warranted for three (3) years from the date of purchase. Replacement products will be warranted for the remainder of the warranty period or thirty days, whichever is longer.
I had to RMA this same PSU I bought from directron.com when it was 4 months old.
