More Information

This is what im building:
 
2x 8800GTS OC
 
Q6600 OC
 
7200.11 500gig HD
 
4gig ddr2-800 ram
 
XFX 780i Motherboard
 
7 120mm case fans
 
DvD Burner
 
 
Basically i want a PSU thats in the 750w range, that will guaranteed run these w/o a problem.
 
I also want it to have no LED's.
 
Money is a huge object here lol. $150 give or take is what im willing to spend off newegg (before rebates)
 
I'm planning on getthing this:
 
http://www.newegg.com/Product/Prod [...] 6817171024
 
it has everything i want, and it comes in a combo deal w/ my case. The only problem i have with it is that its a T4 psu.
 
There is a gamexstream  out there that also has everything i want in a PSU, except its a 700w, and it has a blue LED...
 
http://www.newegg.com/Product/Prod [...] 6817341002
 
IF i could disable the LED, and the 700w would be enough i would rather go with that since its a higher tier PSU.
 
 
Thansk in advance for the advice

I don't think that gamexstream has enough PCI-E connectors to do SLI. Try and get something from as high up this list as possible: http://www.tomswiki.com/page/Tiere [...] ngs?t=anon

im told single rails are horrible for SLI. Puts too much strain on the PSU on bootup or something along those lines

the gamexstream has 2 6 pin pci-e connectors. if i wanted to SLI a card that need 2 6 pin per card, 750w wouldnt be enough, and ide need a new PSU anyway.
 
i think the best a 750w can do is dual 8800GTX, and that really isnt a big step up from dual 8800GTs's. unless i can get a significant performance increase from an upgrade, i wont upgrade it... So if i was to ever upgrade video cards, ide need a new PSU.

True in some cases but to be fair you aren't leaving yourself with a large amount of high quality options with a budget of $150. At the moment the coolermaster you selected probably looks like the best option if you want to have more than one +12v rail.

Oh yes sorry I forgot the 8800GTS only requires one PCI-E connector so the gamexstream would do, although you don't want LED's

so they saying in that link that the rails act as circuit breakers, i get that. So would a single rail PSU put any parts in my machine at risk?

 

i just find it hard to believe that i get some people saying single sucks and some say multi suck...

 

would single or multi rails effect overclocking at all?

 

i honestly never had a single rail PSU so i dont know what to expect.

Get the PC P&C Silencer 750 PSU, it's a top tier PSU at a ridiculously cheap price. Cooler master has a reputation for junk PSUs i.e., tier 5. The larger ones are supposed to be better but I wouldn't buy one.

 

Single rail is far better. You do need to be more careful because of the higher current limit but you don't have to worry about rail balancing. Where did you hear that single rail gets overloaded on boot? I call BS, it's exactly the opposite. Do you have a link? The higher current limit won't damage any components, they will only draw the current (amps) that they need to run. Just be careful not to short anything out when you build, which you need to do anyway if you care about your rig. A lot of PSUs are going single rail because it is better. Many of them advertise multi rail and they are really single rail. here is a little blurb from PC power about PSUs. Power Supply Myths Exposed!

 

And here is a ranking of PSUs Official XS Tiered PSU Manufacturer Brand Listing Phase III.

 

If you don't buy the Silencer 750 you are making a very big mistake. That's cheaper than what I paid for my Silencer 610.

 

That 750TX PSU is also a good PSU with an astounding price, so I guess either one.
