Need help choosing power supplies

[Viper27]

My power supply has been giving me fits for a while now.
I've heard my seasonic s12-600W rev. A2 PSU has problems with DFI SLI-DR mobos.
On occasion, the yellow LED under the PCI slots will start to blink and I can't boot until it stops anywhere from an hour to three days later.

If anyone has a good explanation, I'll gladly do my best to fix it, but I think I need a new PSU.
Having said that, it's been a while since I've looked at any, so here's what I came up with.
Let me know what would work best. (i don't do any overclocking)

CORSAIR CMPSU-620HX 620W
http://www.newegg.com/Product/...x?Item=N82E16817139002

ZALMAN ZM600-HP ATX12V 600W
http://www.newegg.com/Product/...x?Item=N82E16817379003

SILVERSTONE DECATHLON DA650 ATX12V 650W
http://www.newegg.com/Product/...x?Item=N82E16817256021

Antec NeoPower 650 Blue ATX12V 650W
http://www.newegg.com/Product/...x?Item=N82E16817371010

Thermaltake W0106RU 700W
http://www.newegg.com/Product/...x?Item=N82E16817153039

SILVERSTONE ZEUS SST-ST65ZF 650W
http://www.newegg.com/Product/...x?Item=N82E16817163108

I know jonnyguru's website gives the Zalman and Thermaltake PSUs both a rating of 9, but I'd like more input.
Thanks

The best 2 you have listed are the Corsair and the Silverstone. Either one of those will have more then enough power for your system.

You don't have SLI-ed 7800gtx's, right ? If not, then go for this one: http://www.newegg.com/Product/...9001&Tpk=corsair%2b520

It's still PLENTY of power for your rig. and will allow you to power a brand new qaudcore system, with a 8800gtx, 4gb of ram, a couple of hd's, optical drives, casefans etc etc. All the other options you've listed are overkill for your rig, because under load your rig won't pull even half the power those psu's can deliver.

My entire system (besides what's on my profile) has one 500GB IDE drive, a 7200RPM SATA, and a 10,000RPM SATA.
Plus I have 4x 80mm case fans (2 with LEDs) and a single 120mm fan.
I also have two lightscribe DVD R/RW drives and a floppy drive hooked up too.
I don't know if this makes a difference at all.

An even better PSU option would be Corsair's new 450VX. Its a 450W unit that offers 33A on a single +12v rails. More then enough power for that system.

http://www.newegg.com/Product/...x?Item=N82E16817139003

Its Corsair's nerw budget line of PSUs. They also have a 550W model. Its a great deal for only $80.

The 450w corsair MIGHT be a little on the low side though when he wants to upgrade, for his current rig it will do just fine though. But if the new 9x00 series draw more power then 8800's * which I hope they don't being 65nm * then it might be pushing it a little, especially if he oc's his rig. I know his rig wont come near 300w right now, and won't hit 400w with a gtx in there, but still. Both are good options, and for future upgradebility the 520hx would be my recommendation.

The HX620 also scored a 9 @ jonnyGURU. Out of the psu's that you listed I would choose the Corsair.

Good point. I do hope that the power requirements drop. Ideally I'd like to see the new PCI-e 2.0 power spec turn out to be a waist. We can only hope a video card will never need that amount of power.

Another vote for the Corsair. :thumbsup:

Corsair 620HX, I love this PSU. Works great in my rig and pretty quite

600+ is overkill. Get a good 500W.
