Ultra X3's 2000W Modular PSU - Page 6

post #51 of 72
ok, first off never change the breaker size in a panel and leave the wire. Wire size it rated by amps. #14 wire is only rated to 15 amps. #12(yes smaller number=bigger wire) is good for 20 amps. So if your have a 15 amp breaker thats the reason. If your go above the rated amperage the insulation melts off and it WILL start a fire. Don't just switch out breakers.

Second your higher voltage household item run on what's called a 2 pole breaker. This uses both phases of the 2 phase system. Basiclly two breakers tied/made as one breaker. This makes both phases feeding the object go off if one of the phases trip. If your 2 pole breaker says 15 amps on it it does not add up to 30 amps. If either phase goes over 15 amps the breaker will trip.

The typical wiring in a house will very greatly by the age of the house. Most older house 20+ years alot of your general pupose outlets will be 15 amps. It's still not upcommon though as people try to be cheap. Smaller wire = cheaper = lower amps. The typical Hot water tank and dryer use a 30 amp 2 pole breaker. Stove is 50 amp 2 pole . IF electric furnace that will vary more, see alot of those at 60 amps 2 pole though. Gas furnace is sinple pole 20 amp though. Hot tub 50 amps 2 pole. In the USA those are the typical sizes

The typical household panel has 30 spaces and is good for 200 amps. Now you can fill all 30 spaces with 20 amp breakers and that is just fine. That's could equal 600 amps though oh my gosh. Well in reality people don't use all there available outlets/ run everything at the same time. Most people use about half of there panels amp rating at the most.

Honestly I don't know what experience some people have but I'm an electrian and don't just give advice cause you think you know. This isn't a game and you can get seriously hurt thinking you know what your doing.

ALso, the standard household outlest will melt at the 15 amps and I guarantee 98% of houses have 15 amp outlets, not 20.

well, I just skimmed through it and it isn't that good. The explanations about wire size are decent but there table for ampacity per wire size is completely wrong, at least according to the National Electrical Code, which governs most everything electrical in the USA

is your looking for that ampacity of wire this is the table Linky

That's kind of what I was thinking. I think that this is Ultra's attempt at showing the performance market that they don't suck as badly as we think that they do.

Now this is simply insane and wrong. The world is experiencing a power shortage and it's this reason it's doing so.

Instead of forcing by public demand that hardware vendors cut the power consumption of products, we have vendors trying to cash in with another "My Johnson is larger than your Johnson" deal.

It's not speed that counts if there's a brown or blackout. It's not scores that matter when the k/w price jumps from 8 cents a kilowatt to 16 in summer peak times. It's not bragging rights that count when the AC has to cool off the heat produced by 60A videocards (the hidden cost no one talks about in operating these heaters).

Power consumption for PCs don't need to go higher, it needs to be halved -- 200w is too much when laptops show us it IS possible to run a decent PC without a furnace.

AMEN, AMEN, AMEN!!

We recently installed a large electric water heater (going solar eventually) and it needed a 30A circuit for itself (#10 copper). 1500w refrige operates on it's own breaker, too. Microwave (800w) can't share the same circuit with another appliance if in operation on a standard 15A (#14 copper), without tripping.

These monster PSUs are going to burn down homes, as nowhere do they tell folks to check their home wiring to ensure it can handle the current.
