520W psu or more??

520 will be enough. but if u have the money then why not getting the 620 one  

I'm of the "More PSU is Better" and "Too Much is Probably Just Enough" schools of thought, so....  


Regarding the case: Every couple years you will replace and therefore throw out, or sell, almost all of the bits inside as you upgrade. But a good case is the one piece you can be guaranteed to use in build after build. Interestingly enough, you could make the same point about a good PSU. Get a good case.

Also, something to think about: If you like to tinker with your box, a removable motherboard tray is right up there with a topless 20~something barmaid bringing you your cold ones.   *AND* you don't have to tip it!  

Can I get both?

This is a better PS, buy it from PCP&Cs website it's cheaper.
Silencer® 610 EPS12V Power Supply

Newegg's price

Also I just built two computers one with a P182 and one with a P180. There is no noticeable difference IMO.

The 520w is more than enough.

The 450w Corsair is actually plenty to power that system with a 8800GTX.

The 520w gives you plenty of room, but NewEgg is overprices for that model.

The 520w Corsiar is basically the same PSU as the Silencer except for the wattage. They are all built by Seasonic on the same platform.

PSU has enough watts but possibly not enough amps. Look up the amp requirement for your gpu.

Just read the reviews at http://www.jonnyguru.com.
You will see any Corsair PSU has enough amps to power any Graphics card made today.

I saw your post on another Forum and it appears you haven't really settled on the parts your going to get. I would er on the side of caution. Get a 600W+ single rail so you won't have to worry about that as you make final decisions on what to get. It will also give you a little head room for future changes.

All of the Corsairs are single Rail, though the documentation does not reveal that.

How about the sticker on the HX520 in the picture on jonnyguru.com. And the specs in the review for the HX620 on the same site.The 450 seems to be a single rail but that appears to be the only one.

What I think they found was that the label showed multiple rails, but the guts only contained a single rail. The 520 is a good choice and is enough for the system in question.

I'll have to look at that. If so, that is good but also misleading.

Edit: With a closer look at the HX520 and the addendum to the 620 it appears that they are single rail. Kudos to Corsair. I still don't like the modular ribbon cables. I don't believe it is above board for them to be advertising that they comply with the ATX12V v2.2 spec., but no matter.

I found it on Buy.com for $99.99 with free shipping so the price is good. Certainly a better choice than many of its contemporaries.

The 520 is enough for the system in the OP but I think that he really hasn't settled on that long term, based on his post on another forum.

Yeah, there was a discussion about this somewhere else either here or at techware labs. Apparently they aren't the only ones that do it from what I was reading.

I personally would much rather have a single rail, but for some that are new to building it can be a double edge sword.
