i heard the xfx 650w xxx psu is also made by seasonic. is this true????

Hey guys, I am getting a new i5-2500K system and I was wondering if I wanted to do overclocking as well as SLI two GTX570 cards, what minimum wattage power supply should I be looking at? (i'm also running two 1.5TB HDD's and a SSD)

I have been looking at a number of different power supplies, keep in mind that I'm trying to get a PSU that isn't too expensive. These are some of the PSU's that I have been considering: (take note, most of these are prices from australia)

Antec TP Quattro 1000W - RM705
Silverstone Strider Plus 1000W - RM699
Thermaltake Toughpower XT 875W - RM567
Antec TP Quattro 850W - RM597
Super Flower Golden Green 800W - RM507
Antec True Power 750W - RM417

The best price/wattage ratio would be the Antec True Power 750W but I'm not sure if 750W is enough power to support my system or not..
The next best one would be the Super Flower Golden Green PSU. It has gotten a 80+ Gold certification but I have never heard of the brand before.
The Thermaltake Toughpower XT looks like a good buy to me for 875W at that price. All the reviews I have read says it is a solid PSU. However, it only uses a single rail which provides 72A which some might say is a bad thing and others might say otherwise.
Anything above that has a big price jump and I would only consider a 1kW PSU if I really really need it..

What do you guys think?

Ridiculous name right! lol.
Do I really need 1000W of power? or is 875W enough?
Apparently two GTX570s will require roughly ~220W x 2 at max load ~ 450W
Assuming 83% efficiency 875W ~ 725W
That leaves 725W - 450W = 275W for everything else. Isn't that enough?

Hi, my rig is using about 3-4 years hardware mostly. Ever since I upgraded my GPU to ATi 4770, I think I may need to get a new PSU.
Any recommendations? I prefer to spend a maximum of RM150 if preferred. I'm not planning to buy to a new PC anytime soon.

Here's my rig specifications:
- Intel Core 2 Duo E6300 @1.86GHz (plan to OC to at least 2.4-3GHz in near future)
- Sunbeam Core-Contact Freezer
- Asus P5B-E Plus
- 6GB DDR2 667MHz RAM (2x2GB and 2x1GB dual-channel, maybe upgrade to higher performance RAM to smoother my OC-ing)
- PowerColor ATi HD4770 512MB DDR5 (used to use HD3650, no issues as mentioned below)
- WD 500GB GreenPower SATA2 HDD
- WD 250GB Caviar Blue SATA HDD
- Sony 18X DVD-RW
- 3.5" Floppy Drive
- CoolerMaster 430W Extreme Power (see link for details)

**My power supply doesn't seem to have the 6-pin PCI-E connector, so taught temporarily using the 2-molex to 6-pin PCI-E adapter which is something like this:


I've read back a lot of pages before to gain further understanding, but I think in the end I have to ask you guys.
Furthermore, I've used the famous power wattage calculator from the front page and it still shows that my PSU should be still able to handle all this, even though it seems misleading.
Feels that I've made a bad choice of PSU in the past, but what's done is done.

The problems I faced now:
1. Some strange (maybe knocking sounds) when I perform a cold boot of my desktop. Possible power surge?
2. After using the computer for some time, the monitor shows some very light horizontal lines flowing downwards (which I've never seen before when using the HD3650).
3. The computer unexpectedly restarted once as I checked from the Event Viewer.

I need some advice from you guys about my problem. If you need further details, I'll discuss it here.

Thanks a bunch.

If I were to OC 2500K + Leadtek GTX460 1GB DDR5, would a 500w PSU do fine?

Hey guys. I'll be getting 2 gtx 580 in a few months time. Whats the most suitable PSU for 2 580's?

I've read that the Corsair HX 850W is good enough but I just wanna be sure by asking you guys.

Thanks, can you help me to choose between

Seasonic Silence PRO 80 500watts RM199
FSP SAGA2 500 Watts 12cm Fan (True 500W Watts *Peak 550W) RM175

? Is FSP a good brand?

Huntkey brand not good?

How about Targan

You can consider the Gigabyte Power Rock 390W which retails for RM85 at Czone and Jayacom.

Thanks for the suggestion, i think i'll grab that one.
