Which Powersupply

I have no clue when it comes to powersupplies, I used to just look at wattage and think that was all that mattered, but now I see that it isn't and I dont' know what is better.

Sigma Shark 635watt - $90


OCZ StealthXStream 600 watt - $80

Which of these two would be better at powering a 4870, E8500, 1HDD 7200 rpm, 4 gigs RAM, etc...??? Back in a different thread someone recommended the OCZ instead of a PSU that came with a case i was asking about. If I plan on going Crossfire, then what should I get?
 
what's the max you're willing to pay? i consider corsair, PC P&C, and seasonic PSU's to be the top, but only certain models of antec, OCZ, enermax, and thermaltake are also good. the rest are mediocre or poor.
 
seasonic M12 series 600 or 700w
corsair 620hx
or PCP&C 750w

if there's one thing you should avoid doing, it's being cheap on a PSU. good clean power through strong rails is VERY important to the longevity of a computer.
 
well, budget wise...I'm thinkin $150 max. See, my brother thinks PSU's are pretty much a waste of money once you go above like $100. I kind of have the same opinion, but mine involves over $200, but I don't buy really expensive parts that require that much wattage and stuff.

I had wanted modular, until I started reading more about them and realized that a lot of people actually don't like them a lot.
 
It looks like your mainly looking for budget, which we all are, But lets face it man. These crossfire set ups that we all want love power. Your system would be much more reliable when with a powersupply somewhere along the lines of 750 and up... I myself would recommend that you wait untill they come down in price if you want something cheap and find one close to 1000 watts. WOW I know right? There up there in price right know. You also need to research if your Gfx cards connect to the powersupply directly like alot of the requirements call for now. Let us know what your thinking.
 
well, justin52493x2, the crossfire was something i was MAYBE thinking about. I'm not really a fan of SLi or Crossfire, cause like what other people have said, it's like 1+1=1.5. I personally would rather just buy a newer better card that would out perfrom the crossfire/sli set up. The only reason I would go crossfire/sli is if I have a little bit of money and want an upgrade thats a lot cheaper than buying a new single high priced card. Like right now, I have an 8800gt, I don't know how good it perfroms in sli but i'm sure that a 4870 would be better, (maybe the even same, from some of what i have read), but if I have 2 8800gt's then in the future I have to get a newer better card. As opposed to just buying a new one now, then in the future I have the option of choosing another high card, or just getting the same for crossfire/sli.

Also, I always thought that if you had way more power than you needed than it was wasting the power, and possibly money. Or at least thats whay my bro always tells me.
 
If I were you, i'd go with the OCZ PSU. OCZ is a very reputible brand, and make very high quality products. And I agree with you, X-Fire/SLI is pretty much 1+1=1.5. UNLESS you go with a card that has 2 GPUs in one, such as the 4870X2

MMezna, Yeah, I have gotten many recomendations for the OCZ and it looks for high quality. I believe that is my choice.

A PSU will only draw as much power as your system needs. It's true that a PSUs efficiency drops somewhat at very low loads, but for this to be noticeable at all you'd have to be drawing less than about 1/4 of what the PSU is capable of providing.

agreed, make sure you get a quality unit, not just a cheap one/
