My brother is looking at power supplies for his new build and wants to buy the first one on the list below. I am telling him he needs to get the third one listed. Help settle this disagreement. Which one do you guys suggest.

Thank you.

out of those, yes the last is the best but what is this for, i reckon he would not need that third one and that there are better ones out there to suit his needs.

I am using the first one on the list (APEVIA ICEBERG ATX-IB680W-BL ATX12V / EPS12V 680W Power Supply With 3-Color LED Lights) and have not had any problems with it. But now days people are saying not to use tier 5 or 4 PSU's. But I have had mine for about 2 years now. It has more cables than my brother wants to use, so he wants to go modular.
The following is going to be his rig.

QX6850 3.0Ghz
Zalman 9700
ASUS P5E
4Gb Ballastic PC2-8500]
Sapphire HD3870 512MB
320GB Seagate SATA II
500GB Seagate SATA II
2 x Sony DVD RW AW-G170S
PSU--????????????????
Antec 900
Vista Ultimate64bit SP1

Anyone have any suggestions for a modular PSU with Blue LED's.

He would be fine with the Antec Earthwatts 550w, Corsair 520W, PC Power & Cooling 610W, or Antec NeoPower Blue 650W if he likes the blue LED style. All of those are much higher up the quality tier as well (12v rail is the most important thing if you're searching for reviews).

Slightly OT, but wondering why he's going with the P35 P5K Deluxe? For that price you can almost get an X38, which allows for full speed/electrical CrossFire down the road if he wanted to do that as an upgrade. When a P35 board says it has two PCI-E 16x slots for graphics cards, look closely and it will say that only ONE slot runs at full 16x speeds, the second slot only at 4x - which limits even the 3850.

Otherwise, for P35 boards, I'd start at the $100 range and work my way up for features on the board I need.

Anyway good luck to the two of you with the build!

I posted the wrong motherboard. His is the ASUS P5E.
