I would imagine your PSU will handle it, if it is 400w or above it will be ok.
What people do not realise is that components actually use LESS power now than they did a few years ago, yet people panic about their PSU power and because the market is pushing closer and closer to 1000W and above as standard people think they need that sort of power to run dual and quad core CPU's.
You don't mate, if your not running any heavy card then a good 400w will be ok, but if your pushing a GTX then get a 500w just in case you need to push lots of usb devices and extra hard drives in there at some point.
What is the spec of your current PSU?
Also your into copter sims, I have no idea how demanding thery are but best bang for buck is the 8800GT 512mb which can be found for about £140ish. If they are not too demanding then maybe a 8600GT for about £50 will do you.
Their latest PSU is the PurePower PST520W. W00073 being equipped with Active PFC,
This new PSU promises a steady flow of power at 520W, and uses a P.S.T. so that its cords are arrayed in a manner allowing thus a more effective air flow in the PC case.
Features
The PSU main features are exposed below:
- Ingenious Modularized Cable Management and Power Station that allows you to arrange cables easier and smarter.
- 5 .25” P.S.T fits any 5.25” driver bay and offers various connectors for all peripheral devices
- Mini P.S.T offers convenient output for devices and accessories at various locations
- Blue LED around 5.25” P.S.T socket to illuminate your system
- Rubber Sleeved Cable increase air flow and decrease clutter inside the chassis
- Active PFC, improve energy efficiency and reduce current load on AC delivery systems
- Protection against Over Power, Short-Circuit, Over-current, Overload, and Over-temperature
- Safety / EMI Approvals: CE, CB, TUV, FCC, UL, CSA, and CUL certification (For Active PFC). FCC, UL, CUL, CSA certification (For Non PFC)
- Dual 6-pin PCI-Express connectors for High-end VGA card

and the helicopter sims I think a 256mb 8600 would be fine, so maybe the 512mb would be better, or go dual sli
