After 6 years, my PSU finally died.
I'm looking for a roubust/stable/premium PSU that should last forever(a very long time) - in the 750-850w range. Fancy lights are not necessary.
I have a C2Q, Gigabyte UD3P, 8gigs RAM, ATI 4870, 6 hard-drives, etc.
I'm looking for a PSU that can easily handle this and perhaps a HD5970 or 2x 5870s in CF.
I also live in a tropical area with a high ambient temp, so the psu needs to easily handle high-temps & humidity.
I hope I never need to fuss with the PSU again. Just put in and forget.
By far my favorite would be a Corsair 750TX or 850TX. I have the 750 running an OCed i5 750, two OCed 5850s, a GT 240 for PhysX, a sound card, two hard drives, and 6 case fans on top of the aftermarket CPU and GPU heat sinks... it's a solid PSU.
The "HX" version is just as good but adds modular design for a little more cash. I'd say with an 850TX you'd be rock solid for a long time.
Corsair and Seasonic are two brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models come with a 7 year warranty.
I'd recommend a modular PSU since they help reduce cable clutter.. They are priced a little higher compared to the non-modular one's but IMO its worth it.. Also, its good to have as much headroom when considering a PSU.. A 750W model will surely handle your rig.. Getting a 850W model though will give more headroom and operate nearest to the 50-60 % load level wherein the PSU's are at their utmost efficiency.. The XFX 850W Black Edition, Corsair HX 850, Antec Signature 850 and the Seasonic M12D-850 are the recommended models here..
Actually like Emperus said the XFX 850 BE is a great psu as it is on par with the Corsair 850HX but cheaper by if I remember correctly 25$ Another good PSU is the XFX 750 BE that should easily power a 5970 and 5870CF as it is cheaper than the 750HX But the safest route and for a budget is the XFX 850W BE.
Emperus - just a quick note about load levels and efficiency. The new power supplies are much more efficient across a very large load level so it is no longer necessary to select a power supply for a 50% to 60% load level. My own Seasonic X650 Gold is a good example. It is very efficient over just about the entire load level from 0% to 100%.
I ended up getting the HX0.
Living in Singapore, I can't just order from NewEgg, so I picked from what's available.
I first looked at Seasonic, but it seems they where all 80 Plus Bronze.
Then finally I got the modular HX850. It was only $10 more than the HX750.
This PSU is more than I'll ever need. I hope this will last and I'll NEVER need to un-screw it/ upgrade from the case, ever.
Actually, the packaging is great. A nice soft box for the modular cables and a carry-on bag. I'll never carry around the HX850, but the bag makes a great sack for a telescope-large finder scope.
Thanks again for all the help guys!
