Hi all

I would like to know what psu I should get for the following setup I don't want overkill so no 1000w psu reccomendations please I figure 600w shoul be enough but I dont want to be underpowered
i7 2600k 3.2GHz CPU sandy bridge
P8P67 sabertooth or P8P67-M PRO motherboard
1tb sata iii HDD
2x 4Gb 1600Mhz ram
1 Gtx460 1Gb or the 768mb version gpu (will get a second card later in the year) for sli

So I want a sli capable psu for the above setup, I used a psu calculator online and it said 530w (I do want led fans and cathode tubes, not worried about sound cards as
I'll be using 2.1 or headphones for the pc I'd like to try overclocking a bit cpu and gpu
 
Check out the Corsair TX650 or the Antec High Current Gamer (HCG 620). They're both around R850, I 'm ordering my Corsair one today as well.
 
I did some extensive research recently when I needed to buy a new PSU. There isn't a lot differentiating the top tier PSUs.

It comes down to budget, brand preference, if you want single rail, and if you want modular or not.

After about a week's research I decided to go with the Corsair TX650W, it's SLI ready, has 80PLUS, has all the current/voltage/power protection.

Again these things are common in most of the top brands, I suppose in the end this seemed like the best value for money for me.

I maybe should have gotten the HX650W instead, it's modular, which helps a lot, as the cables are nice and long, which can take up a lot of case space, but then again it ~R350 more for that luxury.
 
I've started my upgrade (last night - just waiting for the CPU to arrive) I have the Asus P8P67Pro (damn nice thing!!), OCZ 2X2 gig Reapers 1600mhz, popped into a new case, Coolermaster HAF922. Once my 2600k comes (today I hope) I have a new Coolermaster V6GT for it. As for power supply, going to use my trusty Coolermaster 600w Silent Pro M. O ja, GPU - still running my XFX GTX 280 XXX. Yeah its getting old, but still kicks ass!
 
How is the cooler master PSU? I like the brand, have a cooler master cm690 case, but the reviews of the power supplies didn't seem that awesome.

My 600W Pro M was about R1300 when I got it a few yrs back. http://www.pricecheck.co.za/offers/...ent+Pro+M600+RS-600-AMBA+Power+Supply+-+600W/

Standard 600W is about R700 http://www.pricecheck.co.za/offers/369507/Cooler+Master+RP-600-PCAR+eXtreme+Power+600W/

My PSU has had no issues ... runs quiet & reliably! I had it on a Q6600 OC'd to 3.0ghz, OC'd gaming ram @1066mhz the GPU is factory OC'd, plus the big V8 cpu cooler with 3 HDD's. Its handled that all fine.

I have had the Corsair HX650 for a few years and it is awesome.. Have a AMD 965, plenty harddrives and at one stage 2x 5850's and it was perfect. Modular is awesome to, so neat and easy to work with.

I have also been looking around. ( but still DOF :D )

Please could you explain this single rail thing -- sounds like some kind of electronic fuel injection ..........

As far as the modular thing -- I have seen some of the images but not one that shows the whole story.

It looks like your power cables are all seperate ( except for the main ones which seem to be sheathed ) and then plug into the PSU via the case ?

How many connectors do you get on each cable and how many connectors in total ?

Also looks like seperate power leads for GPU ?????

Seems like a nice way to go -- but for an extra R350 HHHhhmmmm


Never seen one of these fancy PSU so bit in the dark
 
Any decent 600W+ PSU would do with plenty of room to spare. Like the CPU is rated at 95W TDP and the graphics cards are rated at 151W TDP each.

My vote goes for the Antec HCG 620W.

I'm running an i7 940 + 2x GTX 460 1GB cards and my PC has never used more than 540W from the AC input, even with heavy overclocking, with a 90% eff PSU - so the components newer drew more than 490W.
Running 2x GTX 460's in a CM 690 case isn't the best choice, because then the bottom card would sit right on top of the PSU with a very small gap inbetween - I know this, because I have a CM 690 II Advanced myself.

I'm not sure if it's worth it to pay that much extra just for a SLI capable motherboard.
Like you can rather buy an Asus P8P67-M motherboard for ~R1400 and then sell your GTX 460 and buy an Asus GTX 580 DirectCU II instead. PointIT is currently selling a GTX 580 for R4300.

...

Well rails are almost like seperate little power supplies inside your supply, like isolation of sorts.

eg if you were to use one 12V rail for the mobo and hdds and the other for your gfx card, or use both to drive the card (most gfx cards have two plugs for the 12V rails),

different configurations have different adv/dis-adv like if they were to blow (very unlikely) or push out more than 12V (again very unlikely) not all the equipment would be damaged.

This is all to show the prowess of your psu and mostly a marketing tool.

Modular just means the various cables can be unplugged, so you just use the ones you need. For example each PCI Express power connector with its cables will have a plug either side, on for the GPU and one to go into the plugs on the power supply itself. The SATA power cable plugs into the PSU and has 4 plugs for the drives, etc.

Modular PSU's are really nice only if you don't use all the cables. You don't plug in the ones you don't need so there's less clutter. If you're building an SLI or Crossfire system with about 4 or 5 drives, 2 DVD-RAM's, couple of fans, etc, you're probably going to be using all the plugs anyways, so it's not really worth the extra money.

I have a modular (OCZ) PSU now, but since I'm using all the cables anyways, I'm just going for the TX650 un-modular one and saving a few hundred bucks, which I'm putting towards an SSD.

Edit: Also, Corsair's 5 year warranty is not too shabby... Don't know if any of the others offer that.

Yeah the CM 690 case isn't that awesome for SLI, but then again my motherboard isn't that awesome either, the cards sit too close to each other, so they'll be close to each other and close to the power supply.

I had SLI previously, 2x 9800GTs, upgraded to an ATI Asus 6870, after the whole experience, I must say that I prefer to get one beefy card instead of two.

As for power supplies, the Corsair has been awesome, I'm very happy with it, and that 5 year warranty does help a lot. I think on the VX range they have 7 years, but not 100% sure.
 
Corsair. HX650 or TX750. Prefer the 4 x 6/8-pin connectors without the need for Molex to 6/8-pin converters.
