What wattage Power Supply?

Helping me? lol It's really simple. If your system needs more 12V power, then the 12V output is the spec you should be looking at to provide it. If that simple advice is too far over the OP's head, he can ignore it. But it's something that is obviously true, and anyone who spends 10 minutes...

What wattage Power Supply?

True, but that's not what I meant by the numbers not adding up. It does make comparisons difficult though. True, and that's the reason I said the numbers don't add up. The difference is, I realize the numbers are off, but I interpreted them rationally given the context of my statement...

What wattage Power Supply?

In other words, you're concerned with what's factually correct, not what's useful or relevant? Your counterexamples were both incorrect and irrelevant, and if anything just showed an inability to interpret the specs. You're comparing the overall nominal rating of the power supply, rounded off...

What wattage Power Supply?

I compared apples to apples in context. I used the only specs the manufacturer made available, but I never misinterpreted them to come to a ridiculous conclusion like "the power increase on the 12v line alone is more than the total power increase of the whole PS".

What wattage Power Supply?

This is a silly argument. I havent said anything controversial. "The thing to keep in mind" is a figure of speech. In the context of this thread, it means when you calculate the amount of power you need, look at the power output of the voltage rail you'll be using. Big deal. Its a spec...

What wattage Power Supply?

Actually I was replying to akshatv - apparently my browser hadn't updated with posts in between. Well, you seem as much or more interested in being right than me, so I suppose I could say the same to you. But since you brought it up, no he didn't prove me wrong. Check the math and compare...

What wattage Power Supply?

No one cares, assuming it's done correctly. Otherwise you're not getting what you paid for. And no - no one would want a bigger PSU because they're lacking in the 3.3 or 5V dept, and yet that's where Huntkey puts their power, which is the point. That and lots of people buy computers with...

What wattage Power Supply?

Well, usually that's true. Most power supplies operate less efficiently when they're way down in their power range. But I think that's more a question of how much power you want to burn. i.e. a big power supply might cost you more on your electric bill than one operating more within its...

What wattage Power Supply?

Just because this is an enthusiast forum doesn't change the general facts, and doesn't make what I said wrong. The vast majority of power supplies in the world are not that great. Lots of people reading this forum have bought pre-built computers, with no idea of what's in the power supply...

What wattage Power Supply?

Relatively few buy Ultra and Corsair, while Huntkey in its rebranded forms is very common. They're a top supplier and one of the most plentiful if not most plentiful coming out of China. The point being - you should keep in mind how power supplies are spec'ed and designed. Don't assume that...

What wattage Power Supply?

Just because most of the power used is 12V doesn't make my post incorrect - it's still completely correct. And the extent to which it matters depends a lot on the design of the PSU. For example, here are some specs on 2 Corsair PSUs: CS450: the 12V section has a max load rating of 35.5A, and...

What wattage Power Supply?

It's true - there are lots of ways to fudge the specs to put whatever you want on the box when it comes to things like "watts". It was not long after CDs came out that I started seeing speakers labeled "Digital Ready" or "Digital Compatible". That was pretty funny. I think the best thing to...

What wattage Power Supply?

The thing to keep in mind is that the power is split up among the output voltage lines. When you buy a 750W PSU over a 500W PSU, you don't just automatically get 250W more to use any way the PC sees fit. It's available as more current to the various 12, 5 and 3.5V lines, but split up. It's...

Processor Brand Survey for Marketing Class

Interesting, since AMD is obviously in the game. It puts a rather ironic spin on dealcorn's opinion that the results would be skewed because this forum would be too informed. Probably more people here saying "monopoly" while at the same time probably more people here who are even aware of AMD...
