Ever tried an 80 dew point day at 100F in New England with your window shut?

 

[Deleted member 217926]

No but since you just described June, July and August in Georgia we all have AC. Up north you are lucky to have a window unit or two. There are certainly people here without air conditioning though. Try living with that for over 3 months every year! It doesn't get really cold here though. We might have 1 or 2 days below freezing in the daytime a year and maybe 15 to 20 days when it gets below freezing at night. An inch of snow or less literally shuts down everything for days.

I'm not doubting that it gets that hot, but is the air entering your PSU that hot? :lol:

You would be very surprised how hot it can get in some places.

Can we PLEASE stop talking in Fahrenheit. LOL such an antiquated measurement. 😛 Darn tooten Americans.

45c is 113f. NO computer gets that hot unless it is outside in the sun in the desert.

also 35-40c is NOT a normal "summer day". It is 95-104f.

Umm, you been to Australia mate? I don't run the AC when i'm not home, the inside temp easily getting to between 30 and 40degC is normal (ok 40 is extreme, but over 30 easily), average indoor temp when someone is home is still only 25-27degC with the Aircon on when its 35degC outside - on 40+ or humidity above 60%, evaporative cooling for the house barely works and the temp inside climbs.

It is very difficult to get a stable higher level Overclock here in the summer. Most stress tests are conducted with an ambient of 21degC! And i live in the southern part of Australia where it's "cool" and low humidity, it only gets worse the further North you go.

The more higher end the build here, the harder it gets in the summer, and the more ruthless you have to be with Cooling.

My brain doesn't do Celsius except when I see CPU and GPU temps. Literally every other temperature measurement I see in daily life is Fahrenheit. That's with two 24/7 weather channels and no less than four 24/7 news networks. Well CNN does switch to CNN International from 2am to 4am and I think they do Celsius then. I have to plug Celsius into google to get a number I can relate to.

😀 Think its time the US of A needs to modernize and adopt metric measurements, even the stubborn as hell UK has done it.

 

[Darkbreeze]

We won't do it! And you can't make us! That's why we fought a war. It wasn't to get free of English rule. It was so we didn't have to use the damn metric system. Hee heee.

 

[chimera201]

You people living in cold countries just need to move near the equator in a tropical climate to understand what 'hot' means. I'm from India and the temps are 32–40 °C (90–104 °F) in summer. 35°C is pretty normal here even inside home in summer.

Just not the metric system. US does everything differently. The world plays soccer, US plays rugby. The world plays cricket, US plays baseball. Traffic rules are opposite. I also heard that to open a water tap you need to open it clockwise instead of anti-clockwise. The world's electric grid is at about 230V, US runs at 115V, Japan being the only other exception.

Speaking of which doesn't it look like the PSU manufacturers are using the 230V only as a trick to sell low quality power supplies since most PSU reviewers are American. Is there going to be a Tier 1 230V only PSU?

US plays RUGBY??? You sure about that? :lol:

I think he tried (and failed miserably) to mock american football.

 

[chimera201]

lol. Ok i used the wrong word since it was the word i knew. Gridiron football it's called?

American Footbal is good enough for everyone to understand...

I ALMOST took it personally that you would call US Footbal Rugby, Rugby is a South African Speciality.

We take immense pride in it here.

Traffic rules - most of the planet drives on the right side of the road, as opposed to on the left.
Voltage - Japan is far from the "only other exception" http://en.wikipedia.org/wiki/Mains_electricity_by_country

I'm told this varies greatly depending on where in india you are; it's a big place. Bits of florida or the more desert-covered areas of the US probably hit those temps too.

Just not the metric system.

Given this has lead to a plane falling out of the sky along with a couple of spacecraft, the US is clearly pretty stubborn. Surely that's reason enough to change.

NZ is nuts about rugby too... I'm not.

Traffic rules are opposite.

Most of the world, including Europe, much of north Africa, the Middle East, China, Russia, and the US, drives on the right side of the road.

Highly doubt this one.

Yeah, this is stubborn US too.

If you're already building a decent PSU with active PFC, adding multi-voltage support would cost at most a couple of dollars and allows you to get 80+ certification. No reason to build a high-end single-voltage PSU.

 

[MeteorsRaining]

Pardon my ignorance guys, but am I seeing it right that US's traffic rules and summer temps are being discussed in a PSU tier list thread!

 

[Someone Somewhere]

It appears it started with a discussion of whether it was reasonable to expect a PSU to see 40C+ input temperature. Then snowballed into temperature units and why the USA is so backwards.

 

[MeteorsRaining]

40C+ temps are kinda hot, extreme conditions IMO should not be brought into consideration unless required. Testing does require it, normal usage doesn't.

 

[Someone Somewhere]

I think that's the point of the arguement - there are parts of the world where, if you turned off the AC during the day but left the computer on, it could hit those temps.

 

[chimera201]

Damn I feel so bad now. I wasn't expecting people to jump on my side statement i made. My main question was on topic.

@Someone Somewhere
I am not looking for a PSU. I am just asking the quality of 230V only PSUs in general. Are PSU manufacturers intentionally restricting the input voltage because it doesn't get reviewed? I have seen PSUs from Corsair, Seasonic that are of lower quality with the 230V restriction

 

[damric]

The temperature rating is there because a majority of computer cases still mount the PSU on top and it sucks in hot air from the case.

 

[Darkbreeze]

I think you meant to say a "number" of cases still mount the PSU there, not a "majority". Clearly top mounted PSU's are the exception these days, not the rule.

And I have to add, damn, I wrote a nice long retort regarding the issues my previous post raised and right in the middle of it my system powered off and back on. A power issue. Now the PSU is showing voltages well below what's acceptable so I'm writing this on my laptop. Damn, almost brand new M12-II Seasonic PSU. I hate having to RAM my OWN stuff. That's why I buy good parts, so I don't have to. Looks like maybe I'll be going Tier 1 choices this time around and use the M12 620w for a backup system.

Anyhow, my average summer temp in Colorado is between 90-104 F so you don't have to live near the equator for that. Our water spigots open counter clockwise like the rest of the world and we actually drive on both sides of the road, depending on the time of day and how many drinks we've had. Just kidding.

I have the same temps here in coastal Virginia. And I have one faucet where the hot and cold turn in different directions...

Ok, I know totally OT, but, I think we were referring to spigot directions, not faucets, which quite often have different opening directions regardless of country or brand. Heh.

I think so.
