Recent Power Outtages, Replacement Power Supplies Options

[Timbo]

Apparently, yesterday was an energy emergency day or something, and entire blocks were suffering power outtages, cause of the increased heat and air conditioning 'n such. Apparently, the fan on my video card has stopped working since the blackout, which either means it just got blown out, or the PSU powering it got damaged somehow. Basically, the system reboots randomly without warning when it's engaged in something graphically intensive (Overheating).

I've already ordered a replacement fan to see if that'll fix it, but if not, what are some decent power supplies that would make good replacements? Might as well go upwards of 500W for this one. I've got a surge protector, so I sort of doubt that the PSU is to blame, but who knows.

Also, any other suggestions as to what the problem might be? The data I've gathered seems to point to a busted fan that's causing overheating, but any other opinions would be appreciated. Lemme know what info I gotta provide, if any. Thanks much

Get a backup battery. Surge protectors wont protect against power fluctuations and if this continues to happen you could start to have bigger problems like hard drive failure and such. They cost like $50 and up at best buy. I know this doesnt answer your question, but suggestions are fun

I guess you are in the hill country? The rolling blackouts are expected to continue through this week until the power plants can get into full capacity production. You may just want to leave your computer off for a while.

it's the same shit they pulled in california, we're getting enron'ed

No. They underestimated the usage because I guess they are stupid and didn't watch the weather and see that it was going to be in the high 90's this week.

This happened in Houston before. Power plants do not produce 100% at all times. Instead they limit their production to conserve fuel until they need more output. It takes a couple of days for plants to recover from things like this because it usually blows transformers or generators because of the increased load.

Parts of Houston went without power this afternoon as grid operators shut off service to make up for a shortfall of about 1,000 megawatts caused by the convergence of power plant maintenance season and exceptionally warm weather.

Beginning sometime after 4 p.m. today, officials with the Electricity Reliability Council of Texas, which monitors the grid for 85 percent of the state, turned off about 1,000 megawatts of power. What other parts of the state were affected is not yet clear.

The power emergency occurred due to a combination of factors, according to an ERCOT spokeswoman. April is typically a month where grid operators in Texas encourage power plant operators to schedule annual maintenance since the weather is usually mild.

Temperatures throughout the state have been warm, however, and power demand reached more than 40,000 megawatts over the last few days.

ERCOT officials put out a notice to the media this afternoon saying there was not sufficient generating capacity to reliably serve demand, calling it "an emergency situation."

"Therefore, it is extremely urgent that all electricity customers in the region reduce their use of electricity to the lowest level possible," the statement said.

Recommendations for cutting power use include setting thermostats at 78 degrees or higher, not using lighting, appliances or other equipment unless absolutely necessary for health or safety, and not opening refrigerators and freezers more than necessary

"ERCOT is doing everything possible to return to normal operations. However, if conditions do not improve ERCOT will be required to direct the interruption of electric service to portions of the region," the statement said.

At 3 p.m. today, ERCOT operators made a request to power plants in the service area to provide all the resources they could because of an increased demand in power.

At 4 p.m. ERCOT officials then asked for users with interruptible load agreements, namely some industrial power users who can stop using power on short notice, to make available some 1,150 megawatts of their demand for the rest of the system.

This second step usually takes care of most power demands the state faces, an ERCOT spokeswoman said, but it was not enough. Shortly after 4 p.m. 1,000 megawatts of "firm load" was cut.

Why don't they halt the maintenance and reschedule it when temperature cools off? There's supposed to be a cold front coming in soon. Secondly why not March? It's much milder than April.

Don't you guys remember back when Enron's energy traders were doing this in California? They had some cute excuse for why they didn't have enough power to supply demand and started turning off plants, redirecting power, and hiking rates.

Maintenance on certain things has to be done at certain times and if its essential they usually perform it as soon as possible. They usually prefer safety over an accident. Remember that you are dealing with high pressured gases and electric currents.

Enron was not the main force involved in the problems with California. Instead, it was Reliant Energy. You must remember that Texas is a separate power entity, we don't directly supply power to outside of the state. Instead we supply power to the surrounding states, which in turn use that to redirect their own power.

California was their own problem. Their leaders did not plan ahead for increased fuel (coal and natural gas) costs and in turn their residents paid. Texas was asked to step in because at the time we had excess power that we could redirect to New Mexico.

Not even that much, I got mine for $30 at wally world....

Hey Timbo you may want to check your other fans as well.. chipset if you have one, etc. Might also want to put the video card in a different computer if possible and see if it overheats then. Having your system randomly reboot could suggest your chipset or CPU is overheating though. I've usually noticed when a video card is overheating it just slows whatever game you're playing, and when chipsets/cpus overheat it could cause your system to reboot.
