the evga g2 1000w is a bit over budget i said i can only go for $150 or less, money is very tight and i need more money for other stuff as well. do you think my rig can last without failing and play all games just fine for the next 5 years when i am in college.

and also the g2 1000 is $149.99 plus $6.99 i can't get that its a bit over budget right now: http://www.newegg.com/Product/Product.aspx?Item=N82E16817438010&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-PCPartPicker,%20LLC-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=3938566&SID=

the 1000g is a $10 cheaper is that any good?? http://www.newegg.com/Product/Product.aspx?Item=N82E16817438019&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-PCPartPicker,%20LLC-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=3938566&SID= 5 year warranty is alright for me

also can you include shipping in the cost and no rebates, and i also only prefer newegg and amazon for buying. any other better choices please let me know asap, any brand is fine as long as it will not fail or blow up and work. and thx for the help so far
 
Since the G2 is out of reach, The GS is the next best model. The XFX isn't bad, but the GS is also seasonic built, and comes with a better warranty. PCPartPicker part list / Price breakdown by merchant

Power Supply: EVGA 1050W 80+ Gold Certified Fully-Modular ATX Power Supply ($143.99 @ Amazon)
Total: $143.99
Prices include shipping, taxes, and discounts when available

I would buy a GQ unit, over a G1. They are still FSP built, but are better built units.

If you can afford it, GS. If money is too tight, the GQ will be ok.
 


wow this psu is just perfect and gives an extra 50 watts my only concern is, the cables look a bit short do you think it will work fine in the build, and everything will reach just fine??, and also do smaller psu's heat up faster because of limited space and smaller fan. if those 2 issues are solved, i may just get the gs. and this psu also matches the build perfectly to and 7 year warranty is sweet, sure the 2 290x's will do great on it. and thx for the help btw

lastly another issue is i also looked at the antec high current gamer 900w psu, it got tier 2 on here and pass from johnnyguru: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=211

but a fail from hardocp: http://www.hardocp.com/article/2011/02/15/antec_high_current_gamer_900w_power_supply_review/9

i don't just get it. help, i may get this psu for another build i am doing because the color matches it just good and doesn't antec make the best psu's for ages, and the gq looks kind of bad so i am avoiding that, the price is good tough and the gs's size is kind of bothering me, do you think i will get any issues when building
 
I was just saying on another thread, I really wish they quit having "certifications" based on efficiency solely. They should have voltage regulation certifications. Ripple certifications. Japanese capacitor certifications. If they created bronze, silver, gold, platinum, and titanium based on actual quality, the PSU world would be a better place. Companies would actually care about quality, and new PC builders when seeing a Gold PSU will actually and immediately think, "must be good, it's gold" will actually be right for a change.

Not to mention it's a joke the efficiency certifications are done in a 23C environment.
 
The chinese are improving on cap quality - there's still absolute junk out there, but there's also decent stuff. Good chinese polymers could also be considered equal to (or even superior to) japanese electrolytics. Blanket stuff like that doesn't help.

Honestly, the best thing that could be done for getting rid of crap PSUs would be for the US to ban the sale of electrical gear that isn't properly UL listed (or equivalent; the US doesn't have a single certification program like most of the rest of the world).

Other thing I'd like to see is an ATX v3 with tighter regulation, ripple, and efficiency, and standardised (though still optional) modular connectors. More power on the +5VSB and maybe some kind of +12VSB or +20VSB for USB PD or cellphone charging, too.
 
I know the polymers are longer lasting, but I'm still fond of Japanese electrolytics. If the Chinese capacitors were as good quality, all the OEMs would ditch the Japanese capacitors and save money by going with the Chinese. Mindless of what is said on Jonnyguru, that right there is enough evidence that Japanese should be used. I wouldn't purchase one that uses a primary filter capacitor anywhere other than Japan. Even secondary capacitors, I like my Japanese, though I wouldn't mind polymers from other countries. But electrolytics for sure Japanese.

Until I see actual factual data that proves the Chinese capacitors are just as good, I'm going to stick with my belief in the Japanese. And the U.S. does need better regulations on this stuff. And I agree, a revised ATX spec would be nice.
 


But they're not as good. As I said, I want proof of their equal quality. Take a Chemi-Con primary filter capacitor and a Jun Fu. Which one would you choose?

I wish they did tests. A bunch of electrical engineers should get an assortment of similar capacitors from different brands and countries, and run extensive scientific tests and see which ones leak first.
 
Tomshardware should do an article on different capacitors and test them. They could put strain on them and expose them to great heat. Then see which ones die first and how long it takes. Though realistically a test like so could take years.
 
Then again you can just trust good old physics. If there were capacitor reviewing sites that actually took the capacitors, used professional equipment to measure things like the thickness of the outer sealant, and did other in-depth studies, perhaps hearsay on capacitors would be gone. I don't know too much about capacitors other than how they generally work, but you can take something like a power supply and judge its quality based on its internals, so why not take a capacitor from a power supply and judge it based on how it is built?

I'm quite sure that another factor in capacitor quality is the dielectric substance used inside. Something like the chemical properties of the substance could be analyzed.

To quote Torres:
The two main problems with electrolytic capacitors are the use of a bad sealing and the use of a bad electrolyte. A bad sealing will make the electrolyte to leak or evaporate. And a bad electrolyte can do lots of stuff, the most common ones being vaporizing at a temperature lower than the temperature printed on the capacitor label (making the cap to swell or to explode) and corroding a cheap sealing material and leaking.
Japanese capacitors are notoriously known by their above-the-average quality (good electrolyte and good sealing), while Chinese capacitors have the bad reputation of using cheap electrolyte and cheap sealing, what can lead to the problems we explained. Solid capacitors are also immune to the above problems as they provide the best possible sealing.

Maybe instead of advertising Japanese capacitors, PSU manufacturers should start advertising solid caps. Maybe all solid caps except the primary? I don't think that'd work though because solid capacitors can't store as may charges.
 
Turkey, I own an Asus p2b-b2 with a genuine pentium II 350. As of today, it's seen 18 1/2 years of abuse from OC, storage, freezing and cooking in garage heat in Florida and winters in Tennessee. And yet it still works. Now all that wouldn't mean much except that motherboard contains not a single Japanese capacitor. Personally I think that's testament to a great mobo, but point is, there are several US, European and even Chinese made caps of both polymer and electrolytic types that are every bit as good as the Japanese, but aren't part of the 'hype' that Japanese are good, rest is junk. You say you could care less about the voluntary efficiency certificate because it's a gimmick used for sales etc, yet you have succumbed to the exact mentality. Instead of Gold is good, bronze crap, its Japanese is good, rest crap.
 
I think a lot of it is hard to reverse-engineer. Telling the difference between two electrolyte formulas could be difficult. Predicting which will be better is far harder, especially given it's all mired in trade secrets. Just because it's got e.g. more alcohols doesn't tell you if it would last better or worse.

Plus opening the cap would destroy the seal, I imagine.
 
Grr but I just wish we had actual information. It's all just about what people say. You have people 2014 and prior, even the reviewers on Jonnyguru, scoring against any Chinese cap. Now they all love them. As I said, it's all just daresay. I wish there were actual studies done on this stuff. Everyone says different stuff. Everyone has different experiences. Who to trust?

Opening the cap would destroy the seal, but that'd be the purpose of the capacitor review.

Also, why are solid caps only small? Why can't they be larger?
 
A website and forum devoted to capacitors you say?

http://www.badcaps.net/
 
I've been to that site before! Basically a lot of people ask forum questions about capacitors is what I got from it.

Hey, this is cool. A capacitor in another capacitor's shell. Sort of like... secrets capacitor!

OK, I'll stop the whole inception theme now

As for the US laws, we need a lot more than just PSU regulation
 
See, this is why I am actually highly considering doing electrical engineering instead of computer. I'm going into "Computer and Electrical Engineering" but after my 2nd year in college I have to pick one or the other. I'm starting to lead toward electrical. Laws of electricity exist without computers. Computers do not exist without the laws of electricity.
