anyone used these before, or have it currently?, which one is the best quality here for the price?
haha,, all free shipping

I have an Antec NeoPower 550 and I have found it to be great. I have heard good things about Corsair however.

I have three 520HX power supplies and they have run cool and flawlessly. Previously, I had an Antec Neo 480 which ran way too hot and raised the interior case temperatures, even with the 120mm fan. I also like the modular design of the 520s. There are also better deals out there on the 520s.

Good luck!

I have the NeoHE 500w which is pretty similar to the NewPower 550, both modular, both of SeaSonic build, and my g/f has an Earthwatts in her desktop, which is also SeaSonic built. I've heard great things about both Corsairs, however, but they are more expensive. Given the pricing, I would go with the Earthwatts unless you want modular, then go with the NeoPower. The Corsairs are nice if you have the money to spend on them, but if you are on a budget, the Antecs are great quality for the price.

man this is hard... im about to get neopower 550, since im on a budget

NeoPower's overkill unless you're going SLI/CF

True, you could get by just fine with a NeoPower 430W or a Corsair VX450 if you want to go even cheaper. Even the 380W Antec Earthwatts would run the setup in the sig you have listed, but the 430W Earthwatts would offer some more future-proofing for graphics card upgrades. You may also want to look at the 470W PC Power and Cooling Silencer.

I run a e2160 @ 3GHz with a 8800GT on an Earthwatts 380 (only one PCI-E connector). No problems so far, and at $15 AR, seems like a good bet. You can occasionally find them for $5 AR.

43 people gave that first one a rotten rating. Wouldn't touch that one. I have one of those corsair 520 modulers.

2 640 cards in sli, 2 hd's, dual core chip 4gig memory, 2 dvd r+wr, Sound card, physics card, and some other non essentials. Handles it all without a burp. Looking at the 750 model for next build.

im not going to have SLI settings, in my rig. just one graphics card, 2600pro OC
i know that this card needs min of 400W,

Both brands are good, but Corsair's are typically better. For the price, I'd get the 550VX from buy.com for $60AR shipped. You can save even more using a 5% off coupon.
550VX 5% Coupon

Your 2600pro will NOT need a minimum of 400w. That card + a quad core + RAID + 1-2 PCI cards will come close to 400w.

thats what i found on the HIS website, but i now there are some extras in 400W, it is under 400W,

Before x-mas I was running a free AR Ultra PSU. After deciding that my other components were too valuable to disregard this aspect of my system I put that on my gift list and was given a Cooler Master extreme power duo 650. I can only assume it was defective as it sounded like a plane, so I decide to get a different one. The first thing I did was pay the $1.99 at eXtreme Outer Vision to use the PSU calculator (there is a lite version, but the paid one also gives you the recommended amps). Here is the result I got for my system:

Motherboard: High End - Desktop, CPU: Intel Core 2 Duo E6600 2400 MHz Conroe, CPU Utilization (TDP): 85% TDP, RAM: 4 Sticks DDR2 SDRAM, Video Card 1: ATI Radeon X1950 Pro (since changed to 8800 GT), HDD 10,000 rpm: 1 HDD, SATA HDD: 2 HDDs, DVD-RW/DVD+RW Drive: 2 Drives, Floppy Drive: 1 Drive, PCI TV Tuner - Cable: Yes, Fans
Regular: 3 Fans 120mm; Keyboard and mouse: Yes; System Load: 90 %; Capacitor Aging (+ W %): 20 %.

Recommended Wattage: 408 Watts
Recommended Amperage: +3.3V = 8.0 A // +5V = 20.7 A // +12V = 23.1 A

While you cannot use this to come up with your exact figure, it definitely showed me I had did not need as much power as I assumed I would.

I ended up treating myself to the Corsair 520HX and am extremely happy with it. It is VERY quiet and I like the modular cables. My only (very picky) peeve is that the sata cables only have two connectors each, which meant I had to run two cables to my hard drive area to connect my 3 hard drives. If you can swing enough for this you will not be disappointed.

so fianally, which one should i go with? i will not care about the money, if the psu is safe and i can bet my hardware on it

If money is no issue, then go with a Corsair HX520 if you want modular cabling or VX550 if you don't care or want it. The Corsairs seem to be overall a bit better then the Antecs, even though I would feel safe with any of them.
