Yes, I need your guys help fast! My SinTek 600 Watt SLI power supply is dead. What would you guys recommend I get for a replacement?
I want a black sleeved power supply that's between 600 to 650 watts.
Also while I'm on the subject, I would suggest that anyone who's in the market for a high-end power supply to not buy from SinTek Industries http://www.sin-tek.com/sintek_website_v2.1/sintek_v2.1.html
They are the worst for warranties, RMA and phone support. I sent my defective 600 Watt SinTek Power Supply back to them and followed all the motions to successfully process an RMA with them, they failed on all accounts to even answer their phone or even accept the package from FedEx on all delivery attempts. Their website looks all eye-candy but, don't be fooled.
You have been warned!

Look at the tracking to prove it!

Black sleeve I can't do...but I highly recomend the Seasonic 600. It's silent, powerful, and is recommended second to only PC Power and Cooling. Got mine the other day and I love it.

Ahem, PC Power & Cooling Turbocool 510 SLI. I can't believe nobody mentioned this yet. There's also a 1KW version. Nothing comes to close it, I wish I had one lol.

PC Power and Cooling 510/850 or 1KW, these powersupplies have the most stable rails in the industry.

PC Power and Cooling 510, 850, or 1KW are all great, but their fans run really loud 74 dba +

I've heard the 510 personally and it is LOUD. Rumors I've heard say the 850 and 1kw are quiet, but they run around $400-500. The 510 is around $200 if I remember correctly. The reason I went with the seasonic is because...

1. Cheap for the quality ($140 shipped)
2. Whisper quiet
3. Comparable quality to PC Power and Cooling

People hold up PC Power and Cooling to be the end all of powersupplies. I admit, Jakup's 1kw monster is an end all (except for a quad SLI system...I'm sure you'll need two of those for that :D), but I'm under the impression that I have one of the best powersupplies that you can find for under $150.

I might just do that. Or I might just go with Silver Stone again.

Yes the Seasonic is very good also.

In all honosty, the 510 is fairly loud. My 1KW is quieter, but not by a huge amount. It ain't no 5800 Ultra loud, but I would say its the loudest fan in my system by a small amount.

They do throttle depending on the amount of heat though.

I'd highly recommend the OCZ powerstream line of powersupplies. I have the 520W one and it's dead silent. Never had a problem. And it's shiny and the majority of the cables are sleeved. 2 thumbs up :thumbsup: :thumbsup:

Yes OCZ Powerstreams are good too. OCZ Modstreams are not quite as good, but not bad :D

Actually all you need is this:

Extremetech must have read this thread. It addresses this EXACT issue, and was just posted within the hour or so.

That rocks! Thanks for the link and product info! Remember everybody don't buy SinTek products! They will burn you and refuse RMA on their own defective product. They don't offer any kind of support or back their 5 year warranty claim. Please get the word out on SinTek and how they operate.

DO NOT get OCZ Powerstream SLI 600W if you plan on running 2x7800GTX 512. There is a problem with these PSU where they overheat and showdown when stressed and those cards will stress the PSU because I had this problem with my OCZ powerstream 600W and my 2 7800GTX 512s. (takes breath)

I had to return the OCZ PSU and got SilverStone SST-ST65ZF 650W nVidia Certified SLI PSU. Works flawlessly.

There is post I made about this somewhere here I will try to find

I vote for the Seasonic S12 600w. I have the 500w and it's awesome.

Actually, that's a Thermaltake PurePower 680W, which I have. Too bad, no more rebate but I got it while the rebate was still good. It costed $139.xx plus a $25.00 rebate a few weeks back. It's an excellent PSU IMHO.
