I'm flirting with buying a PC_Power and cooling deal

It's not really stupid as they are the best PSU's available, but I doubt you really need something like that so ya I suggest just getting an OCZ Powerstream 520w.
 
sleeving is stupid its eye candy tha tis all if u even try to tell me the cables stick close togather and makes better airflow i am gonna reply with zipties.

edit: i recommend ocz modstream 450w its modular better than sleeving.

Due to their look, convenience, and cost savings for manufacturers, modular plugs have become a popular power supply feature. Unfortunately, there has been little or no discussion of the impact of this feature on overall performance and reliability. The fact is, modular plugs limit power by adding to electrical resistance. The voltage drop can be as much as would occur in 2 feet of standard wire. Worse yet, modular plugs utilize delicate pins that can easily loosen, corrode, and burn, creating the potential for a major system failure. That's why pros specify uninterrupted wire!

That's one of the most ignorant things I've ever heard. Do you even know what the voltage drop is in 2 ft. of standard wire? Let's pretend this standard wire is the worst 20-gauge crap, we're talking a resistance of 0.02 ohms (0.02V per amp). With good wire, it's more like 0.001 ohms, so the voltage drop should never even reach 1/100th of a volt.

So, even according to PCP&C's own sales hype, modular plugs will not affect the voltage even as much as the 0.5% voltage tolerence in PCP&C's most expensive units.

:thumbsup:

i would recomend the modstream for a mid end system, if you are going highend get the power stream...also a lot of places offer sleeving for you when you buy it...

There might be some truth to that statement, but remember, your quoting from a company that is trying to sell you THEIR power supply. They will tell you anything in order to accomplish that. Any electronics tech worth his pay could prove that to be an exaggeration.

This quote pretty much sealed the deal. I will NEVER buy a PSU from this dishonest company. Anyone who knows anything knows that connectors are 10x more expensive than just straight wire runs.

Ummm....maybe if they first smothered the connectors in peanut butter would this make a noticeable difference.

Thank you for ending a completely moronic paragraph with a bang.

You're right... the voltage drop along 2 feet of wire is so small it couldn't possibly make a difference could it. :disgust:

So lets have a look:

OCZ Modstream 520

Zero Load: 11.44
Test One (367W): 11.94
Test Two (302W): 12.46
Test Three (430W): 11.64
Full Load (520W): 12.28

That's an absolute abortion, now have a look at the Powerstream:

OCZ Powerstream 520

Zero Load: 12.1
Test One (368.5W): 12
Test Two (298W): 12
Test Three (488W): 11.96
Full Load (539W): 11.95

The voltage on the 12V on the powerstream dropped as little as .05 while the Modstream dropped .36...

It's within OCZ's specs.. but way out of PCP&C's +-1%.

What are you getting at. We're talking about voltage drops from straight wire runs vs adding a connector in the loop. A proper way of analyzing this would be to measure the voltage at the source and then at the end of the wires.

PC Power and Cooling convinced me with that bit of marketing. I'll never buy one now.

Correct, while the modular connections would have contributed to those numbers, it's not clear exactly how much unless measurements are taken before the modular connector and at the other end of the wire.

I know you're being sarcastic, but that's absolutely true.

Obviously you know very little about electronics, and you're making yourself look dumber.

I never said I liked OCZ. I never recommended their power supplies. I simply said that your PCP&C propaganda is totally bogus.

What I want to know is how those numbers relate to modular connectors. Are you really so ignorant that you think the connectors are the only variable between those two tests?

I mean, was that a typo or are you actually trying to be deceptive? They put a 620W Full Load on the first PSU, not 520W. Obviously a 520W PSU will with a 620W load will perform a little worse.

 
I mean, honestly, didn't you notice that the website you're quoting gave a much higher rating to the PSU with modular connectors? It's a better PSU, and it actually held up pretty well under the ridiculous load.

Oh, you're right... it was 620W, my bad.

You call that holding up well. 😕
I've seen Antec PSU's run 150W over spec and still keep rails FAR tighter than that.
