ajy0903 Posted September 18, 2008 Share Posted September 18, 2008 Can anyone help me with deciding buying the power supplypower supply ? I live in USA. I want the 850W power supply that support both 4 and 8 pins for 12V cpu power. So, I went to Neweggnewegg .com to check out the power supplies that I want. When I did that, I have seen the customers' review of those power supplies. That made me scared of buying power supply. Cause people had put cons of every single power supplies there are. And all of those power supplies had at least 1 or 2 or more problems with power supplies. Can anyone please help me and recommand me a good power supply? P.S. Should I listen to the customer review of all the power supply products? Link to comment Share on other sites More sharing options...
Kelsenellenelvian Posted September 18, 2008 Share Posted September 18, 2008 (edited) Newegg MAKES you fill out the cons section to.ANyways which PSU's are you looking at?I see some pretty good ones in the 150-200 dollar range.

RJM Posted September 18, 2008 Share Posted September 18, 2008 There is a good thread on deciding which power supply to get over at extremesystems.http://www.xtremesystems.org/forums/showthread.php?t=108088 Link to comment Share on other sites More sharing options...
Zxian Posted September 18, 2008 Share Posted September 18, 2008 Every PSU will have it's manufacturing defects. You're bound to get some angry customers posting about the product.Also - if you're asking these kinds of questions about your system build, you do NOT need an 850W PSU. Believe me when I say it - you don't need that much power. What are the specs of your computer? We'll be able to help you a lot more with finding the PSU that will best suit your needs. My guess is that you won't need to spend more than $100. Link to comment Share on other sites More sharing options...

jcarle Posted September 19, 2008 Share Posted September 19, 2008 Still sounds like you don't need more then then a 450W to 550W power supply. Link to comment Share on other sites More sharing options...
ajy0903 Posted September 19, 2008 Author Share Posted September 19, 2008 Still sounds like you don't need more then then a 450W to 550W power supply.Crossfire/SLI using two graphics card.Each one card requires at least 450-550W for GRAPHIC CARD not the full computer usuage.The requirements you are saying is only use for graphic cardIf you add more, I'm sure you need more.

Zxian Posted September 19, 2008 Share Posted September 19, 2008 That's not true. The recommended power supply rating for various video cards is completely overrated. My system here uses 300W AC (roughly 250W DC) when running at full tilt (CPU and both graphics cards stressed), and it's got less power-friendly components than most systems do. Just because a PSU is rated for 550W doesn't mean that it is quality, or that it can actually produce 550W. I've tested several PSUs that can't run at their maximum power output for more than a minute before turning themselves off.Power supply calculators overestimate the amount of power systems actually draw. Have a look at what some real-life systems draw out of the wall here. Link to comment Share on other sites More sharing options...
CoffeeFiend Posted September 19, 2008 Share Posted September 19, 2008 3. 2x 80GB SATA and SATA2 hdd 4. 1x 200GB SATAThat's a lot of old hard drives (80/80/200). Assuming they each use 10W, and cheap power @ ~10 cents/KWh and average taxes, they cost you about $30 of power per year (not counting possible extra air conditioning during summer).I've seen 500GB drives for $50 a few times before, so the new drive would:-give you 140GB extra space-pay for itself in little over a year in power savings alone (so over 2 years, you'd have 140GB extra for less than $0) -- quicker if power costs more there-make your PC produce less heat, thus making it run cooler, which will also make it quieter as fans don't need to be spinning as fast -- and also due to less drives spinning (and new HDs tend to be quieter too)-less stress on your PSU due to disk spin up (count ~2A per drive)-you'd free up some SATA ports on your motherboard, as well as drive bays (more room for expansion, no need to buy extra controllers, etc)Old hard drives aren't worth using (except perhaps in USB enclosures, for backups and what not). And that's without considering they're mechanical devices so they wear out (older drives are more at risk of failure). New hard drives practically pay for themselves...

cluberti Posted September 19, 2008 Share Posted September 19, 2008 I'm a big fan of modular power supplies, so from what you've got listed here a 625W Enermax MODU82+ would fit the bill nicelyand have headroom for the future (and it's a very efficient power supply to boot).

fdv Posted September 30, 2008 Share Posted September 30, 2008 I'm a big fan of modular power supplies, so from what you've got listed here a 625W Enermax MODU82+ would fit the bill nicelyand have headroom for the future (and it's a very efficient power supply to boot).Here's a few Q's for you about modular PSU's...1. don't you worry that over time the modular plugs would get loose?2. what if in the future you need to replace them because you're rough on them, are they standardized in the industry? Could I buy new modular plugs on their own?(New to this modular stuff... have steered clear out of ignorance of them) Link to comment Share on other sites More sharing options...
MCT Posted September 30, 2008 Share Posted September 30, 2008 1. don't you worry that over time the modular plugs would get loose?the plugs kinda clip in (atleast they do on my enermax PSU) 2. what if in the future you need to replace them because you're rough on them, are they standardized in the industry? Could I buy new modular plugs on their own?yes, i think they r pretty standard.. its actually really beneficial to have one , they r very versitile, u can add/remove unwanted connectors this is good if your into cable management Link to comment Share on other sites More sharing options...
