Hi all! Well, when I posted my last thread, I had a crappy Radeon HD 5450. Now I have a decent Sapphire 1GB Radeon HD 5670 graphics card. It still isn't great for really demanding games, so I wnat this: [url]http://www.newegg.com/Product/Product.aspx?Item=N82E16814161333[/url] I have a 500 watt PSU with it being able to handle up to 600 watts (Like turboboost for the Intel CPU's) Will it be able to handle it? - Regular, run-of-the-mill mobo -7200 rpm Western Digital Caviar Blue -Core 2 Duo @ 3.0 ghz E8400 -Case Fan (120mm) -Antec heatsink with fan and LED -About 7 USB Devices -Microphone -2 Sticks of DDR2 RAM (3GB in total) Thanks in advance!
i'm running a Q6600 overclocked, 6Gb RAM, a GTX 570, 3 HDDs, 2 200mm led fans, 3 120mm led fans, 6 usb devices,and a CD drive on a 550 watt. you should be fine. what brand?
Rocketfish
[QUOTE=Smartuy;35868220]Rocketfish[/QUOTE]god no new PSU stat
Well it seems to be fine so far, it's handled everything from my overclocked GPU running Crysis to having 2 HDD's in it at one time and 12 USB devices [editline]8th May 2012[/editline] also do your homework: [url]http://www.hardwaresecrets.com/article/Huntkey-Jumper-550-Power-Supply-Review/989/10[/url] the rocketfish is this with a different label and tweaked for a lower wattage

How so? Does it not handle power well? Because it seems to be doing pretty well and I've used it for a year now. And about the IED, there have been cases of em blowing up? People seem to say its mediocre at best now, not crap like they were. I'll bear it for now, then upgrade to an 800watt Corsair
They tend to use dodgy parts. At any given moment something could blow and your power supply would die (usually in a mildly "explosive" manner). If you lucky, that's the only thing that happens and the rest of your PC is still safe. If not, I see you buying a new PC in your future.

Most every rotgut PSU can output a maximum of 360W, or 288W at 80% load (due to using diodes instead of a slightly more expensive bridge rectifier.) Not every rotgut PSU can get anywhere near here though, because the PSU designs the manufacturers use are from over a decade ago and put more emphasis on the 5v rail, rather than the 12v rail and one of the mosfets ends up burning. The rotgut PSUs also are usually missing most of the coils and caps, which makes the ripple current on the output DC dangerously high, and doesn't filter the backfeed from the mosfets into the mains.

Yeah seriously. I had a coolermaster, which isn't that bad of a brand IMO (but I wouldn't say they are best known for really good PSU's... they are more known for having really top quality affordable cases and heatsinks and stuff), and after 5 or so years (which is a decent lifespan, but not ideal) it straight up caught fire. And by that, I mean last week. When a good quality PSU goes out, usually it simply doesn't work anymore, and your parts are safe. When a meh quality PSU goes out, it can catch on fire, but HOPEFULLY still not fry any of your parts (it's a small fire). Poor quality PSU's will straight up spark, crackle, burn, and/or produce minor explosions, and they have much shorter tolerances/lifespans. There's also a very high chance these PSU's will straight up FRY your system internals, requiring you to get a new computer, and you generally lose everything on your current one. So moral of the story, just do yourself a favor and stick with Corsair. If you want to save some money, I feel like Antec and Thermaltake are also pretty good, though not at the rediculous quality bar that Corsair usually sits at.
would a 430w PSU handle the stuff in the first post? A corsair one

And by that, I mean last week.[/QUOTE] 5 years is a really long life for a PSU. I had a Cooler Master PSU that lasted a whopping 7 years until one day it just shut off and never turned back on. What usually wears out on a PSU first are the capacitors, which can often be replaced and have the PSU go for another 5 or so years. Sometimes parts of the PSU can be improperly cooled (especially if dusty) and heavily loaded areas will start to overheat (biasing resistors, etc.) and those areas burn/explode. The worst PSU damage I've ever had to repair was on an Antec ARIA case. It had a proprietary PSU with shitty Fuhjyyu/Teapo capacitors that caused a zener diode to overheat to the point of actually burning a black hole in the board. I had to do tons of trace re-routing with wire jumpers to make the thing work again, and so far it's not had any problems in the year+ since I fixed it.
Is this PSU good quality? [url]http://www.newegg.com/Product/Product.aspx?Item=N82E16817371004[/url]

The 500W doesn't really fullfill the same purpose as the others. [editline]10th May 2012[/editline] [QUOTE=Smartuy;35896622]would a 430w PSU handle the stuff in the first post?

Heh, while we're on the topic of PSU's, I think I had mine go in a spectacular fashion today. It's been working fine for the past 3 years or so, but my PC runs hot so that probably didn't help. After moving my desktop back to on top of my desk in the hopes of having it run cooler, I got 2-3 blue flashes along with some crackles/pops and now the PC won't turn on. I'm hoping that only the PSU went, since it just came with the case and wasn't anything fancy. There doesn't appear to be any physical damage to the mobo or anything else, mobo capacitors look to be intact, is this good news? I'm gonna take a proper look at it tomorrow with a friend, hoping it didn't fry everything
Just because the capacitors look fine, doesn't mean the motherboard is fine. Usually when a surge finds its way into the motherboard, it takes out the CPU, NB, SB or small logic ICs around the motherboard. Most of the time you can't actually see the damage, the motherboard just won't boot or will just start smoking.
I didn't notice any smoke. Would this affect the harddrive, GPU, etc as well? Or would just the mobo be dead? If it's all gone I'll use it as a chance to upgrade but it still sucks
When I work on computers with exploded CPUs, the part that is most likely to be trashed is the motherboard. The CPU is next likely, followed by slotted addon cards and RAM. For some reason, I rarely see molex powered devices be damaged by a failed PSU. But the only way to really be sure is to test each part with a known good PSU and hope for the best.
