What PSU for this build?

I'm building a desktop but I seriously do not know what PSU to buy. Already bought everything else except the PSU. I'll try to be concise as possible.


Case: Cooler Master HAF 932

Motherboard: Asus Sabertooth P67 B3

CPU: Core i7-2600k

Video Card: (2x) MSi N560GTX Ti/OC Twin Frozr II

RAM: (4x4) 16GB RipJaws X DDR3 1600 PC3-12800

HDD: Western Digital 1TB Caviar Black

SSD: Crucial M4 64GB

Blu-Ray Drives: LG Black

Fans: (1x) 50mm Evercool Fan
(7x) 120mm CoolerMaster Red LED Fan
(2x) 120mm Corsair Fan
(1x) 140mm CoolerMaster Fan
(1x) 230mm CoolerMaster Red LED Fan

Liquid Cooling: Corsair H100

PCI: Linksys Wireless-G Adapter



I'll most likely study the principles of overclocking and overclock the CPU. I'll also most likely get fan controllers and memory card readers.


EDIT: A friend of mine is willing to sell his Corsair TX850W for $80, should I buy it?

You could probably run it on a quality 650W. 750W would give you a little headroom and not stress the PSU as much.

That being said, you're not going to get a quality 650 or 750W for $80. Corsair PSUs are great and that's a downright AMAZING deal on a exceptional PSU, I'd take it in a heartbeat. You won't need another PSU for years.

Something has changed. I am going to opt instead for an XSPC Rasa 750 RS360 using 6 Scythe Gentle Typhoon on a Push/Pull system. Do you still think 850w would still suffice?

I think that if you want to go with watercooling, then you want a custom loop. No real point in getting one of the pre-made kits.

I'd use the H100 over a pre-made kit. It will be plenty for you. And yes, the HX850 for $80 is a steal, and more than you need.

H80 has also been tested on the front page, and was an exceptional performer. All the other all-in-one liquid coolers have been beaten by high-end air heatsinks for the same price. IMO go with the H80 or H100, but you don't need anything that powerful for a cool running processor like the 2600K.

I do not mean to be rude but is 850W still enough if I add 6 more fans and a pump?

Fans and pump are a negligible increase. The pump is maybe 10-30W while fans, vary significantly but are also generally low powered. You can see for yourself the exact increase by looking up the specs for the pump and fans.

A quality 750W PSU will be fine.

Apologies. For some reason, only the first part of your statement registered in my mine. BTW though, it's TX850; regardless, it's still a steal.
