Are modular PSU necessary?

Which one should I get?

Non Modular
CompUSA.com: Thermaltake ToughPower 750 Watt ATX Internal Power Supply Unit - W0117RU - Computer Upgrades » Power Supplies

Modular
CompUSA.com: Thermaltake ToughPower Cable Management 750 Watt Power Supply Unit - W0116RU - Computer Upgrades » Power Supplies

Note: Disregard the price as I wont be paying that much for it after discount.

the defining difference between a modular and a standard PSU is the fact that you can add/remove PSU cables as necessary. i.e. rather than having an extra chain of say four molex connectors you can remove that cable. it only really aids to make cable management an easier job.

edit: may also advise against a thermaltake PSU. the toughpower series isn't "bad" per-se, though their are probably better PSUs out there at a better price-point.

What hardware are you goint to run from it?

If you're going to use a single CPU and video card, I'd suggest a Hiper Type-R 580W

I have that power supply, powering an Athlon 64 X2 4600+, an 8800 GTS, 3 x 120mm fans, a water pump, 2 hard drives, and a DVD burner
