700W will be more than necessary.
obviously a good brand psu

No, it doesn't.


Just echoing two of our PSU experts (Phaedrus and Shub), a quality 650W is plenty and will leave room for SLI. Also, I wouldn't worry about things like fans, HDDs, SSDs, etc. They take such a minuscule amount of power that they're normally not even considered. SSDs also use less power than HDDs, just an FYI.

Thread Starter 
Thought I'd post this to clarify my problem that I'm haveing atm.

Quote:
Got a new SSD today and installed it into the system, tried to install windows onto it and I couldnt get it to install, the system got to the first restart and went into a cycle where it would restart get to the loading animation and then restart again.

I though hmmh this isnt right so I unplugged all my HDD and Blu-ray drives, still same problem. Then I thought, ok I'll try it with a different GPU. Put in an old X600 GPU. The problem disappeared. Booted into windows fine and works grand.

I put my GTX 570 into the system and it lets me boot into windows but its really really unstable. Restarts out of the blue if i try and do anything at all on the system.

The GTX 570 has no problems when its not being used with the SSD. If i boot to my standard HDD windows install which isnt plugged in when the SSD is I dont have any problems at all. Sometimes I got the same constant reboot cycle with the HDD but that was due to a damaged DvD drive which I've replaced.
Think thats the PSU guys?

Looks like a nice new 650W PSU is being ordered tomorrow if you think that this should fix the problem

Like most ppl here have said, 650w+ for future SLI. A 700w for more hhds or anything else you ever need.

Are you opposed to spending a little more up front to ensure long term reliability? I would go 750 if you plan to sli, just the extra amperage on the 12v is worth it IMO. When buying a powersupply you should be looking at amps and not watts... Watts can be very misleading, alot of brands use wattage to sell a PSU. For your computer Id probably run what I have now, the Corsair hx750 80+ silver (rebranded Seasonic which rates it Gold). Quiet and very under rated. If you want to save some cash, the Thermaltake Toughpower xt 775 is another great choice.

Not the PSU.

NAND SSDs consume power by the milliwatt, and it's pulled from a completely different rail (+5V, rather than +12V like the GPU and CPU).

Thermaltake Toughpower are ok, though usually poorly priced compared to the competition. If you see a Toughpower for $120, it's safe to assume that there's a Corsair or Antec available for $100-$120 that's better. Not always, but usually.

The PurePower / TR2 line are trouble, particularly those TR2 RX units.

No experience with that line, heard horror stories. But no problems with the toughpower xt.
